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


Bushidrill has the look of a typical Japanese samurai from the Edo Period. He has his hair bundled up into a topknot, a goatee and very prominent, but slicked eyebrows.


As the oldest member of Atomic Samurai's disciples, Bushidrill acts as the more mature and wiser one 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 he is happy to eat sushi, as well as when Okamaitachi falls for a handsome monster.

As a disciple of Kamikaze, Bushidrill was recruited after an apple cutting test. As Kamikaze has the ability to tell how a person lived their life by cutting with a sword, he only recruits disciples if they pass his test.

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

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 them that their role is to lighten their master's burden. Okamaitachi attacks with his Air Blade, but Devil Long Hair stops it with his hair, shocking the swordsmen.

The demon-level monster then extends his hair toward Iaian and Bushidrill, and the swordsmen prepare for battle.[6]
