Character from One-Punch Man by ONE & Yusuke Murata
Atomic Samurai's top disciple — an A-Class swordsman who lost an arm to a monster and kept fighting, because his master would accept nothing less.
Iaian is Atomic Samurai's strongest disciple and a high-ranking A-Class hero. He lost his arm during the Monster Association arc and continued fighting. He is loyal, skilled, and the kind of secondary character who shows the audience what 'strong' looks like when Saitama isn't around to redefine it.
Lean with light hair and an eye patch. He wears samurai-influenced armor and carries a single sword. After losing his left arm, he adapted his fighting style to single-arm techniques.
