Atomic Samurai

Kamikaze, better known by his hero alias Atomic Samurai, is the S-Class Rank 3 professional hero of the Hero Association and one of its most powerful members, a swordmaster and part of the Council of Swordmasters.

Arrogant, condescending and often jocular, Atomic Samurai refused to even shake Saitama's hand upon meeting him, dismissing him for his low rank at the time. He's notably sensitive about being called middle-aged, yet cares deeply for his disciples, pushing them to keep improving — insisting his disciple Iaian continue training in swordsmanship even after losing an arm. He strongly dislikes being seen as weak, nearly losing his composure when Sweet Mask claimed superiority over him, though he humbles himself readily around people he genuinely respects, like Bang.
