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 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.
Bushidrill, Okamaitachi, and Iaian are waiting outside discussing about Garou's hero hunt, while their master Atomic Samurai is attending a meeting with the Council of Swordmasters. After Atomic Samurai killed the monster Haragiri, Atomic Samurai then declared they will strike the Monster Association.
He, Iaian, Okamaitachi and Kamikaze go around killing every monster they can find until the Association calls them in. They soon return to the Hero Association HQ where they are informed of the Monster Association hideout in Z-City. Okamaitachi decides to leave to take a shower when Sweet Mask shows up. While Okamaitachi was enamored with Sweet Mask, Sweet Mask quickly dismiss the inadequate members.
He and Okamaitachi save Gearsper from monsters.
Bushidrill, Iaian and Okamaitachi enter the Monster Association HQ.
Bushidrill, Iaian and Okamaitachi encounter Do-S and the mind controlled mercenaries. 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. 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 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. 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. After a prolonged battle, the three swordsmen defeat Devil Long Hair by cutting off his hair.
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. Unable to slice the monster's liquid body, the swordsmen are thoroughly defeated.
The three swordsmen are then swallowed up by Pig God, who found them and consumed them, and manages to bring all three of them up to the surface and regurgitate them without any noticeable injuries.
