Also known as:
Loyal Knight of the Fianna
First Spear of the Knights of Fianna
Diarmuid Ua DuibhneWP (ディルムッド・オディナWP, Dirumuddo Odina?), Class Name Lancer (ランサー, Ransā?), is the Lancer-class Servant of Kayneth El-Melloi Archibald in the Fourth Holy Grail War of Fate/Zero. He is a chivalrous servant who wishes to do his best to serve his Master and obtain victory within the war for the Grail. He shares a bond of mutual respect with rival Servant Artoria, wishing to face her in an honorable duel to the death.
The son of DonnWP, foster son of Aengus ÓgWP, and first spear of the knights of Fianna. He is known as Diarmuid of the Love Spot (ディルムッドの愛の黒子?), due to a magical love spot granted to him by a young girl. Any woman who gazes upon the spot instantly falls in love with him, which eventually leads to an encounter with Grainne, the bride of Fionn mac Cumhaill. Gráinne, having fallen in love with Diarmuid at her wedding party, placed a geis upon him to run away with her.
It has been said that, even while at large, Diarmuid stuck to his fidelity to Fionn and did not lay a finger on Grainne. They were pursued relentlessly by Fionn, but after much blood was shed, he decided to recognize their marriage, granted Diarmuid a proper title and land, and welcomed them back as subjects.
Sometime later while hunting with Fionn, Diarmuid was fatally injured by a Demon Boar, the reincarnation of his half-brother. Fionn, who had the ability to transform spring water in to a powerful healing agent was with him, so he had no fear of death. Fionn only needed to walk a few steps to the nearby spring, but with jealousy and hatred towards Diarmuid on his mind, he spilled the water twice. By the third time he went to scoop water, Diarmuid had already succumbed to his wound.
Diarmuid is regarded as a remarkably handsome young man with quirky long hair combed backward in a rough fashion that has a strand hanging down his face. He wears a dark teal outfit, similar to that of Cú Chulainn's. due to their shared Celtic mythology.
Irisviel instantly notes that his features are capable of sweeping a woman's heart at a glance. It is described that the bold features of his face are the high bridge of his nose and his valiant eyebrow. His hard cut mouth marks him with a stoic air, but his eyes seem make his gaze even more brilliant. Takeuchi considers his charm point to be his droopy eyes and button of a mouth. He has a strong, attractive manly scent that rises from him.
She soon realizes his elegant air of beauty is somewhat unnatural. Even though his features are considered handsome, much of it comes from his spiritual power charming women due to the curse of his beauty spot.
Diarmuid is an extremely proud and noble knight who wishes to serve his lord to the best of his abilities. The geis laid upon him by Gráinne was taken by Diarmuid as a test of his pride. He never once blamed her for forcing it upon him, and he truly admired her ability to throw away her pride, title, and future for the sake of her love. He was constantly distressed by the fact that he betrayed his lord, and even as he died while Fionn did nothing, he did not blame his lord for his actions. Diarmuid believed that despite the cruel twist of fate that led him down this path, the days spent with his lord and his love were used to the fullest.
Diarmuid sees the Grail War as a miracle that will allow him to regain his pride as a knight by fighting noble battles and delivering the Grail to his Master. He sees no use in wishing upon the Grail, as simply being summoned has already half-fulfilled his greatest desire. If Diarmuid appreciated Kayneth's talents and experience, then Kayneth would have treated him with a much softer attitude. To Diarmuid's disappointment, Kayneth doesn't believe him in the slightest and constantly looks down on his pride as a knight. He constantly berates Diarmuid, believing that Diarmuid plans to betray him and take his fiancee, Sola-Ui Nuada-Re Sophia-Ri, by using his magical spot. He is also a coward who constantly make demands that would have Diarmuid betray his code and win by all cost. Despite his Master's distrust and lack of character, Diarmuid remains extremely loyal, though he fears that Sola-Ui's attraction to him will eventually cause him to betray his Master once more. He happens to be a submissive man as he constantly took abuse from his Master while offering little resistance to stop it.
Diarmuid adheres strictly to the codes of chivalry and upholds his pride as a knight to the fullest, steadfastly believing in honor during battle. While being pursued by the knights of Fionn, he refused to fight against his former comrades. Despite having been presented with several chances to kill either Artoria and Kiritsugu, he refuses to do so due to the circumstances with which he can do so are against his code. During his battles with Saber, he attempts to provide for the fairest conditions possible. His code and pride also forbids him to ignore evil. During the Caster crisis, he even goes as far as to fight alongside Saber, acting as her "left hand", after she suffers the crippling wound from Gáe Buidhe in order to be able to face her in battle again in the future. He is willing to go so far as to destroy Gae Buidhe, so as to allow Saber to use her Noble Phantasm to destroy Caster, simply because Caster himself is a great evil that has to be wiped out, despite the fact that he himself has nothing to gain from it.
Lancer is summoned by Kayneth El-Melloi Archibald in the fourth Holy Grail War instead of the Rider-class Servant, Iskandar, whose catalyst was stolen by Waver Velvet. The contract formed with Lancer is unique in that while Kayneth holds the Command Spells, the energy to materialize Lancer is maintained by Sola-Ui, Kayneth's fiancée. Lancer, on the orders of Kayneth, actively makes his location known in order to entice a battle, while Kayneth hides his location. Saber and Irisviel von Einzbern answer this challenge, and eventually Lancer attains the upper hand by successfully striking her with Gáe Buidhe.
Before their fight can continue, Rider interrupts the battle, then followed by Berserker, and Archer. Once Berserker begins to attack Saber, Kayneth orders Lancer to join him and finish her off. As it is against Lancer's code of honor, Kayneth uses a command spell to force him to attack. Rider, who holds similar values of honor to Lancer, decides to force Berserker to retreat, and threatens to face Lancer with Saber if Kayneth doesn't back down. Lancer is later berated for his actions, though Sola-Ui cuts it short by criticizing Kayneth for not actively participating. Lancer stands up for his Master, who is irritated by Lancer because he believes that Sola-Ui has become infatuated with him. Before the issue can be addressed, their base, Fuyuki Hyatt Hotel, is attacked by Kiritsugu Emiya and Maiya Hisau, who destroy the hotel's foundation and collapses it around the three.
When Kayneth and the other Masters are offered a reward of extra Command Spells for defeating Caster, Lancer is sent to kill off the magic-wielding Servant, who at the time is engaged in battle with Saber. With Saber's help, he is successful in dispelling Caster's monster army with Gae Dearg, but abandons his duel with her in order to rescue Kayneth from Kiritsugu. Rendered bedridden and unable to perform magic, the injured Kayneth is forced to hand over his remaining Command Spells to Sola-Ui, whose infatuation with Lancer has escalated to near-obsession. Lancer is uncomfortably disturbed by how his current situation resembles his past life.
Lancer plays a key role in defeating Caster, when the Servant summons a giant monster to wreak havoc on Fuyuki City. He willingly destroys Gáe Buidhe in order to remove the enchantment inhibiting Saber's abilities, allowing her to employ her full power and destroy Caster.
Lancer returns to the last location where he and Sola-Ui were supposed to meet, only to find Sola-Ui's severed hand. Lancer returns to a displeased Kayneth, apologizing profusely for failing to protect Sola-Ui. He tries to ease Kayneth's displeasure by informing Kayneth that Sola-Ui is still providing Lancer with mana, meaning she is still alive. Kayneth remains furious and openly mocks Lancer, on top of threatening to use a Command Spell he obtained from Risei Kotomine to force Lancer's obedience.
Saber and Irisviel later confront Lancer to finish his duel with Saber, but both are unaware that Saber's Master, Kiritsugu, had already formulated a plan to eliminate both Lancer and his Master. They have an equal battle for a time, though Lancer is unsettled by the fact that Saber is simulating the injury from Gae Buidhe. He believes it is out of pity, but she corrects him in that fighting with honor is the only way to draw out her true strength.
The battle ends when Kiritsugu, holding Sola-Ui and him hostage, coerces Kayneth into using his last Command Spell to force his Servant to commit suicide; Lancer is thus forced to drive Gáe Dearg into his own chest. The shocked Servant realises that he has been fatally betrayed by his current Master, just as his former master Fionn had caused his death during his first lifetime. Enraged with his one wish being denied again for others', especially his Master's personal gain, Lancer dies cursing the Holy Grail, Kayneth, Sola-Ui, Saber, Kiritsugu, and the world at large for his fate.
Einzbern Consultation Room
Lancer appears in the Einzbern Consultation Room, a metafiction segment analyzing the story, that takes place after he dies and becomes absorbed into the Holy Grail. Lancer has amnesia due to the mental trauma caused by the various events of the Holy Grail War, only remembering certain key parts that gloss over his misery. He enters the dojo believing it to be a school of martial arts that he can challenge, but he is told by Irisviel von Einzbern that they provide consolation. Student 0, temporarily falling under his curse, consoles him on not being able to remember his Master and his wife, telling him to forget his painful past, including his relationship with Grainne. Though she convinces him that he must have died nobly in combat against Saber, Lancer wishes to progress a proper and noble Grail war to a romantic relation with Saber. Irisviel, acting as an agent for the Grail's corruption, brings back his despair by making him remember the true nature of his death before being fully absorbed.
Lancer appears as an unlockable character in Fate/unlimited codes. To unlock him, you have to unlock Saber Alter and Leysritt. To make him show up, you have to get at least three KOs with supers (if game is set to best of 3) before reaching stage 5. Beat Zero Lancer and continue clearing arcade to unlock him. He is known as Zero Lancer (ゼロ・ランサー, Zero Ransā?) with the title Loyal Knight of the Fianna (忠誠なるフィアナの騎士, Chūseinaru Fiana no Kishi?). Unlike the other characters, he lacks any sort of story mode.
He notes that it is an undeserved honor to receive the chance to take up arms again, saying that he will not let the chance go to waste. Should he defeat Saber, he exclaims that it was the conclusion he had sought, and that he is thankful for having the opportunity to challenge her once again. He also notes that it is an unbelievable honor to face Lancer, a memory he will cherish deeply.

Fate/Accel Zero Order
Diarmuid challenges Artoria Pendragon to a duel at the wharf. He goes there ahead of her and Irisviel, but he becomes trapped in El-Melloi II's Unreturning Formation. When the stone maze is disabled, he is left confused and confronts Ritsuka's party. El-Melloi II asks him to calm down while revealing his True Name and explaining they're not Kayneth's enemies. Diarmuid leaves with Kayneth after the latter agrees to meet with El-Melloi II later tonight.
Meeting with El-Melloi II later that night, Kayneth and Diarmuid are both convinced by him that the Archibalds created Chaldea's technology thanks to Kayneth's leadership. They then accompany Ritsuka's party to Gilles' hideout in the sewers. After Gilles is killed, Kayneth and Diarmuid leave for the church to retrieve an additional Command Spell.
Eventually, they meet with Ritsuka's party again. El-Melloi II convinces Kayneth that the war is a farce created by his family's enemies, the Trambelios, in collusion with the Tohsakas, to lure him away from the Clock Tower and increase their influence over the Association. Diarmuid is ready to accompany his Master to London to stop the Trambelios, but Kayneth, but Kayneth orders him with a Command Spell to stay and continue the Grail War for his family’s reputation. He then lends Diarmuid to the group for that purpose.
The group meets up with Kariya later then disrupts the discussion between Artoria, Iskandar, and Gilgamesh to kill Gilgamesh. After Gilgamesh perishes, however, Lancelot attacks Artoria when Kariya collapses from expending too much magical energy. The group helps her fight Lancelot, but Iskandar soon stops the fight. He warns her and Diarmuid that they'll be his enemies if they ally with El-Melloi II. Diarmuid considers defeating Iskandar on Ritsuka’s order, but El-Melloi II reminds them they’re only allowed to defeat four Servants. After Iskandar leaves with Kariya and Lancelot, EMIYA arrives to kill Irisviel. EMIYA is defeated in the ensuing fight, and he is convinced to join the others and go to the Grail's cavern.
There El-Melloi II explains the Grail's corruption and is initial plan to safely dismantle the Grail. However, the plan was changed to destroying the Grail directly with the failure to recruit Iskandar. After defeating Hassan of the Hundred Faces, the group moves on to Grail's chamber, where they defeat Iskandar. After he disappears, though, El-Melloi II is ambushed and rendered unconscious by Lancelot, now Zouken Matou's Servant. The others kill Lancelot, but that, unfortunately, triggers the Grail's activation. Zouken uses Irisviel's magical energy to hasten the process. A figure resembling Irisviel called Black Iri then emerges from the Greater Grail and proceeds to devour Zouken. She then goes to devour the group, saying five Heroic Spirits aren't enough to fill her. Artoria and Diarmuid hold her off while the others escape.
Unfortunately, she and Diarmuid struggle against Black Iri, but thankfully the others return to assist. Artoria recognizes Waver Velvet (who joined the group) has become a Servant, which unbeknownst to her resulted from becoming Zhuge Liang's temporary vessel. After the group destroys Black Iri, Diarmuid hopes to meet Ritsuka's party again, suspecting it'll be when the world's at stake before disappearing due to the Grail's destruction.
Summer Event: Chaldea Summer Memories
Diarmuid and several other of Ritsuka’s Servants are accidentally rayshifted to a remote island where they’re unable to contact Chaldea. He agrees with Fionn that the men should act discreetly with so many beautiful girls around to avoid troublesome incidents, noting that his liege understands himself well. When Cú Chulainn asks if the Fenian Cycle always begins with a skit, Diarmuid apologizes for his liege's behavior. He claims Fionn is only eager to deepen the bond with all the Servants here.
Fionn is the first to notice Blackbeard wash ashore when the latter returns from observing the island. Diarmuid thinks Blackbeard is someone who drowned at sea and drifted to shore. He considers giving him proper burial until Blackbeard regains consciousness. Blackbeard explains their location is still unknown, and it's nearly impossible to escape by ship. He then disappears in rage, cursing everyone for trampling on his dearest wish. Diarmuid strangely feels a deep affinity for him. After Scáthach alters the female Servants' Spirit Origins to give them swimsuits, Diarmuid denies Fionn's accusation that he'll use his Love Spot to his advantage.
At some point, Fionn, Diarmuid, and Cú Chulainn founded a secret village for the men.
When the crops are destroyed, Fionn uses Fintan Finegas to determine the culprit is a four-legged beast. He and Diarmuid then stand guard. But during their watch, they're both gored by a demon boar.

Final Singularity: Solomon
Valentine Event The Bountiful Chocolate Gardens of Valentine
Diarmuid helps plant cacao trees to produce more chocolate, even though it unnerves him that is's for the “evil” ritual of Valentine's. He nearly criticizes Semiramis for it until he sees one of her dove familiars. Cú Chulainn orders him to make scarecrows with the materials he got from the warehouse before leaving.
Later, Diarmuid, Cú Chulainn, Vlad III, and Karna find themselves unable to harvest cacao plants crossbred with mandrakes thanks to its scream. Semiramis told them the plants must be harvested today, as they'll likely wilt by tomorrow. Cú Chulainn go gets Nero Claudius and convinces her to sing by saying music helps plants produce a greater yield. With Nero's song countering the screams of the cacao mandrakes, and their ears protected by runes, the Lancers are able to her harvest the plants. Everyone soon finishes and Nero leaves, satisfied that she could help. Karna however points out that they have another field to harvest. Cú Chulainn leaves to go get Elizabeth Bathory.
Twin-Spear of the Rose
Diarmuid confesses a portion of his Noble Phantasms' power is sealed. Romani Archaman deduces Diarmuid sealed his Noble Phantasms himself either due to an error in the summoning or a subconscious effort. He, therefore, suggests diving into Diarmuid’s mental landscape to solve the issue. While Diarmuid rejects it, Ritsuka accepts it and the group enters Diarmuid’s mental landscape.
There, led by Diarmuid, the group partially undo the seal on his Noble Phantasm after defeating the guardians of his mental landscape, the seal on Diarmuid’s Noble Phantasm is partially undone. Afterward, they proceed to Fionnl‘s castle. There the Knights of Fianna explain that Fionn is waiting for Diarmuid elsewhere.
After defeating the knights, the group confronts Fionn in the forest where Diarmuid died. Fionn accuses Diarmuid of being unable to truly get over his regrets and resentments over his death. He then reveals himself to be the manifestation of his resentment. Diarmuid defeats Fionn and accepts he holds some resentment towards him. Thanks to his decision to hold onto something precious to him, his Noble Phantasm is completely unsealed.
- Lancer was featured in Chariot Man: A True Tank Man (戦車男, Sensha Otoko?), a parody film of Densha OtokoWP. Lancer is the son of Sola and Kayneth and the older brother of Waver Velvet, he loves his sister. The story is expanded in TYPE-MOON 10th Anniversary Phantasm comic. Diarmuid was insulting Iskander's lack of gift knowledge when Waver was gifted with a Saber figure. The discussion came to an end when Waver dived to save the figure. Diarmuid still doesn't approve of their relationship. He accidentally trips but he was saved by his mother and his mother was saved by his father.
- He was featured in Mysterious Planet An Sa Ra (不思議惑星アン・サ・ラ, Fushigi Wakusei An Sa Ra?).
Lancer is called Diar-something-kun (ディルなんとか君, Diru-nantoka-kun?) in Fate/GUDAGUDA Order.
Diarmuid is an extremely accomplished spearman, capable of skillfully using two spears of different lengths with blinding speed and agility. Diarmuid has exceptional speed, the highest rank possible for a Servant, and a high Strength rank, though the rest of his statistics are much lower. Although his basic parameters are not particularly high, he excels at using battle tactics designed to trip up enemies stronger than himself. In particular, he is the natural enemy of those Heroic Spirits which rely on the power of their Noble Phantasm to fight. He obtains no geographical boosts from the cultural sphere around Japan, and due to his greater mana supply from his Master, he is stronger than Cú Chulainn in terms of pure firepower. Should both of them fight in Ireland, Cú Chulainn would gain an edge over him. Although Lancelot was a powerful enemy against all other teams fighting in the Fourth Holy Grail War, Diarmuid would have an advantage against him due to compatibility. Also qualifying for the Saber class, it is likely that it was Kayneth's original expectation to have summoned him in that form.
Diarmuid has amazing warrior prowess as seen in his fight with Artoria, where despite having his back turned to her and not seeing her, he was able to put her completely on the defensive, with no opening for a counterattack. Even when he resorts to utilizing just one spear, which is not his preferred style, he is still able to fight Saber without being at a disadvantage. In addition to his close-quarters combat prowess, he is confident that he is able to hit Caster's grimoire from the shore of the river with his lance if he can glimpse it for just a moment. This is a throwback to his legend, where he used the same lance to strike down a flying witch after he was in great pain from having been hit with poisonous darts.
Depending on his strategy, he could have won the entire Fourth Holy Grail War or suffer a humiliating defeat at the hands of Hassan of the Hundred Faces. While he usually follows the codes of chivalry during the War, it would be possible to have him to use underhanded tactics to have a better chance at claiming the Holy Grail. Convincing him that Heaven's Feel is filled with filth instead of an honorable battleground with other heroes and avoiding contact with Saber to keep him from awakening his Chivalric Pride would allow him to utilize Gae Buidhe in a hit and run strategy. Briefly engaging opponents in order to land precise hits with the spear and then retreat would become the main form of attack. He would not directly engage them, allowing him to cripple his opponents one by one by repeatedly attacking them. The other tactic would involve manipulating or taking advantage of Team Berserker in order to let Berserker defeat other Servants and fight him in the final battle.
- Magic Resistance (B Rank): Cancel spells with a chant below three verses. Even if targeted by greater magecraft and Greater Rituals, it is difficult for them to be affected.
- Mind's Eye (True) (B Rank): Capable of calm analysis of battle conditions even when in danger and deduce an appropriate course of action after considering all possibilities to escape from a predicament. He is extremely insightful, as he is capable of leading Saber, whose Instinct skill allows her to avoid danger, into a well thought out trap. By utilizing her lack of knowledge of Gáe Buidhe, he made Saber believe that he had simply abandoned it, and later managed to lure her into a position where he could freely kick it towards her.
- Love Spot (C Rank): A spell (curse) inherent of one's facial features which is cast as soon as the target looks at the user's face; a Mystic Face. Enchants those of the user's opposite sex with magical energy. It is because of this curse that he is known as "Diarmuid of the Love Spot". A woman who confronts Diarmuid gains a strong love affection for him. Effects are similar to those of Charm-type Mystic Eyes. Avoidable with the Magic Resistance Skill.
- Knight's Strategy (B Rank): A battle methodology in which one grasps the flow of battle and induces the opponent to make a mistake, even without being a match for him/her in strength. A Skill not for self-strengthening, but to invite a check failure for the opponent. Consists of composed observation powers to wager on a momentary chance of victory.
His Noble Phantasms are his twin spears, Gae Buidhe, a spear that makes any wounds caused by it unhealable, and Gae Dearg, a spear renders magical defenses powerless by piercing through mana. He keeps them tightly wrapped in amulet cloths from their tips to the handles, sealing their abilities and acting as a counter-measure to avoid revealing their names by hiding the shafts of the weapons. Their abilities begin working immediately after undoing them from their bindings.
Toshiyuki Shirai (Animator Director) first debut in episode 16. His young and vivacious pen draws Lancer and Saber's lively battle, as well as the anguished expressions on Lancer and Kayneth's faces. He said the plan for Lancer's scene was to have him turn into particles of light and fade away. But since he was the type of person who would have cursed everything as he died, Toshiyuki changed it so that he would be enveloped in black mist and crumble away. Even though it was a last-second change of plans, he said it was thanks to the staff who churned out terrific elements, it ended up being a memorable scene.
Creation and Conception
He was a rare character to write for Gen Urobuchi because he normally views beautiful characters as either evil or stupid as an ironclad rule following that, if a man is too beautifully formed, his life would become truly miserable.
Kinoko Nasu carefully picked out the tragic Celtic hero. It surprised him that Urobuchi, who faithfully followed the beginning of Fate/stay night's story where Saber beaten the Lancer at the start of the story, but he also copied its ending where Lancer committed suicide.
He was designed by Takashi Takeuchi as having the manner of an English rocker.
Takeuchi calls Lancer as the faithful dog while Kayneth the stubborn man.
Hikaru MidorikawaWP (Voice actor of Lancer) said Lancer had quite a few of scenes, but he was struck by the scene where he curses them as he dies (episode 16), and by the way he's shown as being so vigorous in the first half of the episode. He was so lively that when he's forced to kill himself, you feel sorrier for him. Midorikawa thought his suicide scene was handled delicately. There's an illustration for that scene in the original (the TYPE-MOON VERSION). But they presented it differently in the anime. Midorikawa was really impressed at how well they pulled it off. Midorikawa wished that they allow Lancer and Saber to go on fighting forever as Lancer seemed to be enjoying himself.
Toshiyuki Shirai said Lancer was really popular at Ufotable, with his, "I'm glad I met you!". He was nicknamed "Sparkling Lancer," and the day after he finished the keyframe art, copies would be posted at the animator's desks, and some of the girls even added world balloons that made him say "My Master!"

Comment for Diarmuid
Takeuchi: At the time and place where I finished reading the first volume, as I thought "Uh-huh, like this", I was able to create the character's form. His clothing definitely has the manner of an English Rocker (a greaser).
Urobuchi: For me, who has an ironclad rule that beautiful people=evil or stupid, he is a really rare character for me. But I really thought that if a man is too beautifully formed, then his life would truly become miserable.
Takeuchi: Everything is best in moderation. He comes from the same Celtic mythology as Cu Chulainn, so his costume design follows the same lines.
Urobuchi: Celtic bodies! For some reason, as it moves from the time of the Gods to the time of Mankind, simplicity is consequently lost and parts increase; what a wild thought!
Sola-Ui: Lord Derry...
Kayneth: Sola-ui? Sola-Ui!
For no reason whatsoever, there are a large percentage of messy hairdos in Zero. [Takeuchi]

 Fate/Zero material - Encyclopedia: Diarmuid Ua Duibhne [Servant], p.100
Diarmuid Ua Duibhne [Servant]
The Lancer class Servant of the Fourth Holy Grail War, summoned by Kayneth El-Melloi Archibald. A hero of the Fianna, spoken of in Irish mythology. The story of his tragic love affair with Grainne would later become the model for the story of Lancelot and Guinevere. It's no wonder that the Berserker of the Fourth Holy Grail War has such bad compatibility with him!
In battle, he wields two Noble Phantasms: the Crimson Rose of Exorcism (Gae Dearg) which temporarily nullifies the effects of magical energy, and the Yellow Rose of Mortality (Gae Buidhe) which inflicts cursed wounds that cannot be healed by any means.
His basic parameters are not particularly high, but he excels at using battle tactics designed to trip up enemies stronger than himself. In particular, he is the natural enemy of those Heroic Spirits which rely on the powers of their Noble Phantasms to fight. Depending on his strategy, it's even possible that he could have won the entire Fourth Holy Grail War (or suffer a humiliating defeat at the hands of Assassin).
Out of all the Servants in the fourth war, he had the second-worst compatibility with his Master. Though, if his very first opponent had been anybody besides Saber, he might have been able to fight in a way more in line with his Master's expectations. For you see, it was Saber's serene beauty and grace which kindled the flames of chivalry within his heart. Also, while he was summoned as a Lancer this time, and therefore carried the twin demonic spears Gae Dearg and Gae Buidhe, his legends also speak of a pair of demonic swords: Moralltach and Beagalltach. So, there was actually a decent chance he could have been summoned as a Saber. Or rather, that's probably what Kayneth was hoping for…

Kayneth El-Melloi Archibald [Person's name]
Kayneth demonstrated genius level talent during his time as a student. He was the youngest lecturer to grace the podium of the Department of Evocation in its history. His skills were not only in research, but also politics. Due to his great lineage, he had extensive connections. He was expected to form the greatest faction in the Clock Tower.
He did not participate in the Holy Grail War due to necessity or duress, it was merely to add a splash of "martial prowess" to his life's story. That was it. Although he did not severely underestimate the Three Founding Houses, he did boast that Lord El-Melloi could overwhelm them by skills alone.
The reason Kayneth brought many dangerous Mystic Code had nothing to do with research, but for entertainment value. Kayneth had talents not only in Spirit Evocation, but also in many fields of magecraft. He was really a man of many talents like Gennai Hiraga or Cao Cao.
Kayneth even considered the Heroic Spirits ---- Servants, to be part of his stock of Mystic Codes. Because he never acknowledged the humanity of Servants, he did not understand Diarmuid's loyalty even until the very end. As a result, he effectively lost through self-destruction.
However, Diarmuid was not choosey of his Master, he would acknowledge anyone who would accept his loyalty. As a result, he did not understand Kayneth as a person either. If Diarmuid really appreciated Kayneth's talents and experience, then Kayneth would have treated him with a much softer attitude.
To Kayneth, unable to bond with his Servant was the second most unfortunate event at the worst. The most unfortunate event by far was encountering Emiya Kiritsugu. Although as a mage, Kayneth won by an enormous margin, as a killer, he was miles behind Kiritsugu. It was inevitable that Kayneth would lose in a melee such as the Holy Grail War. Because of Kayneth's sudden death, his many valuable research accumulated in the Clock Tower was unorganized and left unattended. Although they were almost lost, the most useless formal student suddenly appeared to save the day. He had an unusual talent of "could not put magecraft to practice, but ingenious in the reinterpretation of theories and classification of systems". This student eventually compiled a tome named "Lord Kayneth's Encyclopedia of Arcane Secrets", which laid the foundation for the flourishing of House El-Melloi and its descendants.
By the way, in the Fourth Holy Grail War, the following strategy would insure the absolute victory of Team Lancer:
- Kayneth must not let his Servant recognize such things as honour on the battle field or knights' pride. He must let Diarmuid realize that the Holy Grail War was merely dirty chores that needed to be done.
- In order to fulfill the previous item, Kayneth must avoid any contact between Diarmuid and Saber with his best effort.
- In combat, Kayneth must prioritize securing an exit. In a battle, missions would be considered accomplished if Diarmuid scored one hit with Gae Buidhe. Repeat this tactic, and exhaust all hostile teams.
- Capitalize on Team Berserker. Team Berserker was a powerful enemy against all other teams, but Lancer had an advantage due to compatibility. It would be optimal to let Berserker destroy the other teams and reach the finale. He could then be defeated at that point.
- Kayneth must not let his Servant recognize such things as honour on the battle field or knights' pride. He must let Diarmuid realize that the Holy Grail War was merely dirty chores that needed to be done.

Master Session 002 - Lancer Side
Midorikawa: Lancer had quite a few of scenes, but I was struck by the scene where he curses them as he dies (episode 16), and by the way he's shown as being so vigorous in the first half of the episode. He was so lively that when he's forced to kill himself, you feel sorrier for him. I thought his suicide scene was handled delicately. There's an illustration for that scene in the original (the TYPE-MOON VERSION). But they presented it differently in the anime. I was really impressed at how well they pulled it off.
Yamazaki: I bet that if we'd applied ourselves, we would've been the favorite to win the Holy Grail War.
Midorikawa wished that they allow Lancer and Saber to go on fighting forever as Lancer seemed to be enjoying himself.

Gen: Among Fuyuki's local specialty of Servants, we carefully picked out the tragic Celtic hero, have him commit suicide through a Command Seal to ensure the ingredient's freshness. Our restaurant's main chef is very confident in and highly recommends this Lancer dish. There's nothing better than hearing that you enjoyed it.

Nasu: That also surprised me, it's something to be admired. Please understand the power of Urobuchi Gen, who faithfully followed the beginning of Fate/stay night's story. But... to think he also copied its ending! That person really is a demon! (Biting a handkerchief while crying)
