Caster (キャスター, Kyasutā?) is a Caster-class Servant summoned by Ritsuka Fujimaru in the Grand Orders of Fate/Grand Order.



Caster's True Name is Wolfgang Amadeus Mozart (ヴォルフガング・アマデウス・モーツァルト, Vorufugangu Amadeusu Mōtsaruto?), he is a musician and one of the world's leading genius composer. He is a person from the 18th century, his musical sensitivity is up to abnormal and as an unwavering prodigy, he left behind many musical pieces in posterity.[1]

He was also devoted to the world of the magic. There is a legend which Mozart had connections with a certain secret society that still exists.[1]


He had been called the prodigal child when it comes to performances of piano and stringed instrument, having been invited at the age of 8 to perform for the Empress of Holy Roman Empire, which had been dominated by the House of Hapsburg, Maria Theresa. At the age of 14, he had managed to write out of memory the polyphonic music that had never been taken out from the Sistine Chapel of Vatican for a hundred years just by hearing it once. There are even anecdotes where he put out a composition without corrections, revisions, or even a rough draft.[2]

The child beloved by God. The marvelous genius. Even in Germany and Austria later years of the musical world, where it is said that no figure able to surpass Beethoven could be born, he is a special, unparalleled, perfect existence, extolled by the many geniuses there starting with Brahms.[2]

In his childhood, he was invited to the palace in Vienna and met the girl who shined the brightest: Maria. In other words, the tragic princess Marie Antoinette. When he was still a mortal, he died earlier than Maria. If he had lived, he would not allow her to end in such a cruel outcome from the Guillotine.[1]

Mozart was friends with a fellow musician, Antonio Salieri, who even taught both Mozart's protégé, Sussmayr, and his own son, Franz Xaver Wolfgang Mozart. However, after Mozart's death, Salieri was accused by some to have killed Mozart, a baseless rumor that eventually spread across the world.



A supreme holy man with complete and utter sincerity when it comes to music.
As a human, he only does what he himself wants to do, without understanding or comprehending the feelings of others; a really problematic guy who lives only according to his whims. Due to the music that he plays is that of the highest quality, his character is of one that does not think of people or a relation with them; a personality that raises a certain kind of image in the eyes of the people. Namely, a man like that of the devil.

The person himself is fond of talking with people comparatively, jokes in particular. Generally, his jokes are ones related to music, hard to be understood. The ones that he REALLY likes, the dirty jokes, are intentionally sealed (because his beloved Marie told him to). Still, occasionally he blurts them out anyways.[2]

His music was always devoted to one woman. Secretly, he is delighted to be in the same attribute as his beloved person.[1]

At first, he regarded the Master as someone with a little bit of something in terms of magic, but practically none in terms of music. But as the level raises, he began to hold an interest in him. "Now that I listen to it, it's not bad of a rhythm. No, it's not his voice. Not his words. But his existence." But in the end, it's nothing more than an interest. He realizes that he possesses an inhuman personality, so he wishes to put some distance against those close to him precisely because they are close to him.[2]

His wish upon the Holy Grail is "happiness for Marie Antoinette". For her, shining as she arrived at such a cruel end, to listen for the greatest of piano performance that the current him could do.[2]

Fate/Grand OrderEdit

Orleans: The Wicked Dragon Hundred Years' War Edit

Mozart appears as an ally to Ritsuka and Mash. When Ritsuka, Mash and Jeanne are being overwhelmed by Jeanne Alter's Servants in La Charite, he, along with Marie, suddenly arrives and uses his Noble Phantasm, Requiem for Death to repel Jeanne Alter's Servants, allowing the group to escape.

After the group set up camp in a forest, Marie and Mozart introduce themselves as stray Servants, though he criticizes Marie's infatuation with Jeanne. After Marie agrees to join the group, Mozart cautions her since neither of them have the combat experience of the other, and that their opponents are powerful. Then after Jeanne theorizes that the Holy Grail summoned him and Marie to combat the reversal of causality of the Grail having a holder before the Holy Grail War even began, Mozart again cautions Marie that they may meet more enemies. Later that night, he and the others fight and kill Saint Martha, who tells them to go to Lyon where they'll find a dragon slayer who can slay Jeanne Alter's dragon.

The next day, Marie gather intel about Lyon from a nearby town while he and the others wait outside since Jeanne's presence will terrify the citizens. Marie reports that Lyon was destroyed a while ago, yet despite that they decide to the town to search for the dragon slayer that protected the town. While searching the town, Mozart and the others eventually encounter and kill The Phantom of the Opera. Romani then warns them of a dragon and three Servants coming towards them, but Marie and Mozart stand to fight while the others go rescue the dragon slayer from the town's castle. After the others rescue the dragon slayer, Siegfried, Marie and the others encounter Jeanne Alter and her dragon, Fafnir, who is then commanded to burn them all. But Marie and the others are protected from the dragon's flames by Jeanne and Mash, before they then escape when Siegfried's Balmung causes Fafnir to retreat. While escaping, they encounter a French army being attacked by wyverns, and there, he helps Marie and Mash repel Sanson. After the group kills Lancelot while Carmilla and Sanson escaped, he leaves with the rest of the group.

Arriving at an abandoned fort, Mozart and the others discover from Siegfried that he has been cursed. But, Jeanne is unable to remove the curses due to their multiplicity, so he and the others split up to search for a saint to help remove the curses. Mozart travels with Ritsuka, Mash and Siegfried to Thiers, where they encounter Kiyohime and Elizabeth arguing, much to his annoyance. After they repel an enemy assault, and after dealing with Elizabeth and Kiyohime, the group learns of Georgios from Kiyohime. Contacting Jeanne, the group confirms that she and Marie have contacted Georgios, but then discover that they're under attack by Jeanne Alter. The group tries to leave to aid Jeanne and Marie, but another enemy assault prevents them from doing so. After Jeanne and Georgios rendezvous with the others, Mozart learns from Jeanne that Marie sacrificed herself so Jeanne and Georgios escape. Putting off her sacrifice herself as something Marie would do, Mozart goes off somewhere until the rest are ready to leave. Later that night, Mash talks with Mozart, who gives her some insight into human nature. He then has a conversation with Jeanne about Marie, which ends with Mozart thanking Jeanne for granting Marie's wish for a friend.

The next day, the group decide with a frontal assault on Orleans with Mozart saying he'll distract the wyverns. Later on the battlefield, he and the others are confronted by an insane Sanson, but Mozart's words insulting his infatuation with Marie returns Sanson's sanity. Deciding to avenge Marie's death, Mozart kills Sanson with the help of Ritsuka and Mash. Later with the others, he chases Jeanne Alter back to Orleans when she retreats due to Fafnir's death. Eventually reaching Orleans, Mozart stays outside the palace with Siegfried and Georgios to deal with the wyverns; complaining with them about Elizabeth's Noble Phantasm. Then, as the Singularity collapses after Ritsuka and Mash retrieved the Grail, Mozart commends Ritsuka for a masterful performance before disappearing.

Salomon: The Grand Time TempleEdit

Mozart is one of the "Orleans" Singularity Servants summoned to aid Ritsuka.


In his interlude Symphony of the Heroic Spirits, Mozart is kicked out of a tavern when refused to pay for his drink, which he believes he shouldn't pay for due to his musical talent. Having his instruments taken from him until he pays, Mozart with Mash goes to defeat bandits who've been attacking merchant wagons. After being paid for capturing the bandits, Mozart pays his various bar tabs, then afterwards he goes off to have dinner.

Anastasia: The Permafrost EmpireEdit

Mozart was one of the Servants summoned to the Russian Lostbelt during the world's death throes, however he is gone by the time the Shadow Border arrives.

He was brought before Ivan the Terrible and convinced to keep the Tsar asleep with his music, which he agreed to on the condition that Antonio Salieri, should he appear, be allowed to kill him. Mozart was able to continue his performance for two months straight, playing piano and the entire orchestra as required, and even eliciting praise from Ivan for his lullabies. However, the harsh environment and sheer exhaustion proved too much for his frail Spirit Origin, and by the time Salieri appeared before him, Mozart admitted that he felt worse than when he died of illness.

Salieri vehemently refused to kill him, as it would "make the rumours a reality", so instead, Mozart placed a curse on him: forcing Salieri into "being Mozart" and taking his place as court musician for a time. He reflected on how he had the world's greatest monster dreaming to the sound of his music and the responsibility and power that implied, before fading away.


As a Heroic Spirit, his music magic derived from Orpheus and, according to legends, it has a deep affinity to Solomon's magic. Amadeus is the magus of music. It holds the literal meaning, as well as an exemplification of him being a prodigious musician. As a Caster, he establishes attacks with musical magic using sound as a medium.[2]

According to Mozart, he was a possible candidate for becoming the Demon God Amdusias as he is from one of the 72 magus bloodlines that would become agents for the Demon Gods. However, he sold his soul to music rather than to demons, with someone else becoming Amdusias instead.

Caster's Noble Phantasm is Requiem for Death.


His Class Skill is Territory Creation (Rank B).

Protection of the Music God (False) (Rank EX): Originally, this is a Skill indicating being given the divine protection of Muses, the goddesses of music. It is the capacity to recognize and identify any and all sorts of sound, and it makes it possible to perform a prodigious musical performance. In addition, it also grants a plus correction on the usage of musical magic. Amadeus is able to display this Skill and effect equals to it with his own ability by means of his natural pitch sense, talent, and effort.

Appreciation of the Arts (Rank B): Comprehension in regards to work and object of art. Should he take a look on a Noble Phantasm that possesses an artistic anecdote, there is a high chance of figuring out its true name.

He also holds the skill Eine kleine Nachtmusik (Rank EX), based on one of his famous compositions.


Creation and ConceptionEdit

PFALZ is the character designer for Wolfgang Amadeus Mozart.[1]

Comment from IllustratorEdit

"During the initial stages, I have him concealed with mantle just like Jack-chan, and tries to give off the feeling that as he opens his mantle the clothing themselves looks as if it becomes a glorious opera stage. Which is why there are parts that imitate stained glass and curtains. Like how one would understand from seeing the drawing of his last ascension, with large influence from the movie Amadeus at first I put up a design that blends in various of homages, like Amadeus' father's clothes, or his form when returning to the requiem, but midway I went with emphasizing his arrangement, so it feels like the original prototype design has mostly been removed."[2]
