One-Punch Man Wiki

Bushidrill (ブシドリル, Bushidoriru) is the A-Class Rank 4 professional hero of the Hero Association and a disciple of Atomic Samurai.


Bushidrill has the look of a typical Japanese samurai from the Edo Period. His garb consists of black hakama worn over a black kimono. He has thick black eyebrows and a goatee, and his hair is tied back in a ponytail.


As the oldest member of Atomic Samurai's disciples, Bushidrill acts as the more mature and wiser of the three. He tries to persuade Iaian that fighting Garou singlehandedly would be reckless. He is also quite serious since he scolds Okamaitachi for dancing around when she is happy to eat sushi, as well as when Okamaitachi falls for a handsome monster.

At some point in the past, Bushidrill and his teammates fought Child Emperor and lost.

He, Iaian, Okamaitachi and Kamikaze go around killing every monster they can find until the Association calls them in.

Bushidrill, Iaian and Okamaitachi encounter Do-S and the mind controlled mercenaries.[6] They battle but are interrupted by Sweet Mask. Sweet Mask calls for the swordsmen to leave the battle to him. Initially they leave the monster to Sweet Mask but distrusting his uncompromising nature, they return to battle Do-S.[7] Bushidrill confronts Sweet Mask about his killing intentions on the brainwashed Narinki's Private Squad but is rebuffed. Iaian convinces Bushidrill to drop the matter and they prepare to bring Narinki's Private Squad back to safety.

The sword heroes encounter Devil Long Hair, and Okamaitachi becomes infatuated with the monster, much to the annoyance of Iaian and Bushidrill. Bushidrill and Iaian tells Okamaitachi to snap out of it, reminding her that their role is to lighten their master's burden. Okamaitachi attacks with her Air Blade, but Devil Long Hair stops it with his hair, shocking the swordsmen. Devil Long Hair counterattacks, but Bushidrill manages to stop the attack before any harm was done. The Demon-level monster then extends his hair toward Iaian and Bushidrill, and the swordsmen prepare for battle.[8] After a prolonged battle, the three swordsmen defeat Devil Long Hair by cutting off his hair.[9]

Bushidrill, Iaian, and Okamaitachi pursue a monster down the halls of the Monster Association base. The monster enters a vault and breaks the tank holding the Monster Association executive Evil Natural Water.[10] Unable to slice the monster's liquid body, the swordsmen are thoroughly defeated.[11]
