Berserker (バーサーカー, Bāsākā?) is a Berserker-class Servant summoned by Ritsuka Fujimaru in the Grand Orders of Fate/Grand Order.



Berserker's True Name is Tamamo Cat (タマモキャット, Tamamo Kyatto?), one of the Tamamo Nine. After Tamamo-no-Mae underwent a millennium of training and attained divinity, she cuts off her other 8 tails when she returns to her one-tailed form. Each of her tails is left a portion of her divinity and becomes a Heroic Spirit.[1]


Compared to Tamamo-no-Mae, she has more muscles than the original and is a little heavier.[1]


She is the crystallization of Tamamo's more pure and sincere aspects. She is something like a wild cat that one cannot tell what it wants to do, nor what sort of mess it will make. As a dignity of a wild beast, once someone is served as a "lord" (主?, reads also as "owner"), she devotes her allegiance until the end. After forming a contract, Tamamo-Cat will turn into a guardian beast that wants nothing but to be helpful to her master (主人, shujin?, reads also as "husband"). Once things become like this, protecting the Master, the happiness of the Master becomes foremost and Cat stops thinking about her own joy.[1]

As a Berserker, it is basically difficult to come to a mutual understanding. However it is hard to call it a maddening since Tamamo-Cat had little reason to begin with, but nobody is really mindful for the circumstances are similar. Occasionally she surprises the people around her by muttering suggestive words. She shows no interest anything but tasty things, fun things, everyday fully enjoying a hunting lifestyle according to her whims.[1]


Fate/Grand OrderEdit

Septem: The Eternal Madness Empire Edit

Tamamo Cat materializes on the Shaped Isle, along with Elizabeth Báthory, after Stheno materializes there. They're made her to test out her so-called "Hero's Cave" before the arrival of Ritsuka Fujimaru, Mash Kyrielight, and Nero Claudius. Cat was supposed to come out of the chest at the cave's end as the final trick following the chimera. That never had happened though because she apparently ate it. After the group complete her cave, Stheno introduces Cat and Elizatbeth; they have difficulty understanding Cat's nonsensical speech. She asks her why she didn't come out of the chest, but she deduces what happened when Cat responds nonsensically. Neither Cat nor Elizabeth help fight Caligula when he arrives on the island to kill Nero.

Singing Pumpkin Castle Adventure ~Mad Party 2015~Edit

Summoned by Elizabeth using a fragment of the Grail she found in Orleans, Tamamo Cat is recruited as a maid. After Ritsuka Fujimaru, Mash Kyrielight, Kiyohime enter the castle, Tamamo Cat expresses her doubts that Ritsuka is the last fool to come, though Elizabeth is confused by her strange commentary. She is then asked by Elizabeth if all the prepartaions for her grand entrance are finished, to which she answers that all the food has been cooked. After the group had defeated Mata Hari and Carmilla, Tamamo Cat states that the group is suffering when Elizabeth asks her.

Eventually, Tamamo Cat is confronted by the group in the castle's banquet hall. After threatening to sharpen her claws on Kiyohime's kimono after mistaking her statement of her suddenly appearing as an unwanted compliment, she sends monsters at the group. After the group defeat the monsters then her in battle, Tamamo Cat mistakenly believes that she was victorious. However, after Kiyohime points out that she lost, she decides to lead the group to Elizabeth. Tamamo Cat then leads the group to where Elizabeth is, which to the group's surprise is Ritsuka's room filled with Halloween decorations. After Elizabeth reveals that the event was an elaborate scheme to give Ritsuka a personal concert by her in their room, Tamamo Cat tells the group to voice their opinion on the foolishness of Elizabeth's scheme. She then calls forth some monsters for the ensuing fight after Kiyohime becomes enraged by Elizabeth's scheme. After the group defeat Elizabeth, Tamamo Cat notices Ritsuka convulsing slightly from Elizabeth's singing, and asks the others if they're okay.

SE.RA.PH. - Deep-Sea Cyber-Nirvana, Epic of Remnant: ExtraEdit


In her interlude Overflowing Wildness, Tamamo Cat tells Ritsuka that she wants to go to hunting, and proceeds to have Mash join them by threatening Cath Palug. After rayshifting to the Shaped Isle, the group is attacked by a pack of werebeasts. After the group slay the pack, Tamamo Cat proceeds to go into the forest to catch salmon in its river. However, at the river she encounters Asterios, who has claimed the river as his territory. Tamamo Cat then proceeds to fight Asterios with the others after she mistakes him for five-star beef. After the group defeats him, Asterios retreats, which saddens Tamamo Cat since she wanted to be friends with him. However, she quickly changes back to her usual happy disposition now that she can catch salmon. Proceeding to exit the forest, the group find themselves in a large plain, where they're attacked by David, who has mistaken them for sheep thieves. After David retreats after being defeated by the group, Tamamo Cat ask Ritsuka to stop her should she get out of control. Then, after taking one cattle, she reveals that the salmon and the cattle are the ingredients for the dinner she plans to make for Ritsuka. After Ritsuka and Mash express their surprise at Tamamo Cat's ability to cook, the group return to Chaldea, where she serves Ritsuka a large variety of food items.

Other appearancesEdit

  • Caster Female ending part 2

Along with the eight other Tamamo Nine members, she appears in Caster's ending in Fate/EXTRA CCC.


Tamamo Cat's Noble Phantasm is Opulence of Sun and Shine and Catnap.

Mad Enhancement: Tamamo Cat's Class Skill. It increases her parameters by one Rank, but most of her reason is robbed in return. However, it's hard to call this maddening, as she didn't have much reason to begin with.

Shapeshift: A Personal Skill, that allows her to change her appearance into foxes and badger spirits, that are affiliated with Tamamo-no-Mae. Tamamo-no-Mae showed restraint when using this skill, but Tamamo Cat does not, as she has no self-restraint, self-respect or self-control. Only self-destruction.
