Slayburg

Grimhilde's hero. The King of Heroes.

An incredibly power individual who, in a single hit, ejected the Black Valkyrie Sigrune out of the heavens and struck through the outer shell of Yggdrasil.

He is probably a Takeuchi prototype for Kishima Kouma from Tsukihime. Personality-wise, he is very similar to Kouma as well as Berserker from Fate.
