Okada Izou

He is a lean young man in his mid-twenties with messy, spiky dark hair and sharp amber eyes. He typically wears a tattered, reddish-brown haori over a dark kimono and traditional hakama, with bandages visible around his neck and wrists. Multiple katanas are tucked into his waist, signifying his mastery of various sword styles.

Arrogant, boastful, hot-blooded, genius, insecure, and bloodthirsty.

Assassin-class Servant

One of the four most famous assassins of the Bakumatsu period, Izou was a self-taught genius who could master any sword technique just by seeing it once. After being used as a political tool and eventually executed, he was summoned into the Holy Grail War as a Servant. He struggles with his identity as a "manslayer" rather than a true swordsman while maintaining a fierce, prideful rivalry with his former peers.
