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.


As a Heroic Spirit, his music magic derived from Orpheus and according to legends, it has a deep affinity to Solomon's magic. He usually attacks with music magic that assumed to be a mediation sound.[1]

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.

He is a genius of miracles and a child who is loved by Muse, the Goddess of art. Protection of the Music God (False) (音楽神の加護(偽), Ongakugami no Kago (Nise)?) is a personal skill with the blessing of the Goddess.[1]
