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 is 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 Okamataichi for dancing around when she is happy to eat sushi.

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.

Trivia Edit

  • Bushidrill's title is a portmanteau of bushido, the samurai warrior code, and drill.
  • The origin of his hero name comes from the way his sword strikes that pierce like a drill and from his appearance like that of a stoic and imperturbable samurai.[1]
