Michel Nostradamus is one of the Einherjar set to fight in a future match of Ragnarok.
He is regarded as the "Legendary Prophet" (世紀の予言者, Seiki no Yogen-sha). He has also been described as the "Most Obnoxious Man in the History of Humanity" (人類史上最高に不愉快な漢, Jinrui Shijōsaikō ni Fuyukaina Otoko) by Brunhilde. Because he once destroyed the Bifröst, Notradamus became the only human who's been thrown into Tartarus ever.
Appearance
Nostradamus takes the form of a small and short boy with long, pink and blue hair, and green eyes. He has a feminine appearance.
He wears clothes of rich men from his time period.
When smuggling Göll into Tartarus, he wears a black cape .
Personality
Nostradamus has a goofy, whimsical, excited yet easy going personality. He likes to pull pranks and do things for the simple sake of annoying others (such as wearing Brunhilde's clothes or lying to Göll that he foresaw the Gods winning Ragnarok).[1]

Michel Nostradamus destroys part of the Bifröst just out of sheer curiosity
He is also highly inquisitive to the point of obsession, being that he even destroyed the Bifröst for no real reason, but just out of pure curiosity to know what would happen if he did. He can also be seen as quite cheeky and quite brazen, as he doesn't even care about the consequences of his actions and acts natural and childish.
Brunhilde even told Göll that this personality makes him the most irritating Human in all of history, and that the only reason she brought him to Ragnarok was because Nostradamus is an important and key player in the Humans' victory against the Gods, and even claims that if it weren't for that, she would have sent him back to Helheim with a smile on her face.
Nostradamus does show seriousness when the situation is grave, researching Gleipnir after he was informed about Odin's plan to break the seal and ressurect Yggdrasil. [2]
Abilities
Overall Abilities: Even among the humans who were summoned to Ragnarok, who are considered the strongest humans in history, Michel is considered one of the strongest among them. As the man who nearly destroyed the Bifröst and the only one in all Humanity to be cast to Helheim, Michel Nostradamus is considered by Brunhilde to be her "Wild Card" against the Gods (which is also the only reason she brought him to Ragnarok despite his completely irritating and unbearable personality). Brunhilde even considered using Nostradamus, alongside Qin Shi Huang and Leonidas, against Poseidon in the third match of Ragnarok, this one who was considered the "God among the Gods" and the "Zeus of the Seas". According to Brunhilde, Nostradamus is strong enough to kill the guards and escape from Helheim whenever he wants.
Physician Profeciency: Nostradamus is proficient as a physician, as Odin asked him to be Siegfried attending physician.[2]
Golden Age: As a Human soul in the afterlife, Nostradamus possesses the appearance and skills that he had during his Golden Age, the age in which he was at his peak.
