Okamaitachi has been seen wearing a long sleeved sweater and a long dress. Okamaitachi hair consists of two upward arches split at the neck with hairpins on each side of the head and two large dots on each cheek. Okamaitachi is physically male but a maiden at heart.
Okamaitachi is good friends with Iaian and Bushidrill, though his habit of falling for handsome male monsters annoys his teammates. This habit also extends to handsome men as well, seen when Okamaitachi admired Sweet Mask's looks. He also loves sushi very much.
As a disciple of Kamikaze, Okamaitachi 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 Okamaitachi, Iaian and Bushidrill fought Child Emperor and lost.
Human Monster Saga
The Blizzard Group Arc
Super Fight Arc
Okamaitachi, Iaian and Bushidrill 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.
Monster Association Arc
Okamaitachi, Iaian, Bushidrill and Atomic Samurai hunt through the mountain to look for the Monster Association's hideout and killed any monsters as they came across. They soon return to the Hero Association headquarters 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 dismisses the inadequate members.
Okamaitachi, Iaian and Bushidrill encounter Do-S and the mind controlled mercenaries. They do battle, but are interrupted by Sweet Mask. Sweet Mask calls for the swordsmen to leave the battle to him. They leave and encounter Pig God eating The Great Food Tub and decide to take another route.
The sword heroes contunue to fight monsters and encounter Devil Long Hair. Okamaitachi becomes infatuated with him, much to his teammates annoyance. Bushidrill and Iaian tells Okamaitachi to snap out of it, reminding him 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.
The three swordsmen work as a unit, rushing in and cutting Devil Long Hair's hair as fast and as effectively as possible, and manage to defeat him, although they admit it was a difficult opponent, and had they not worked together, they surely would have lost. But Okamaitachi, Iaian, and Bushidrill are attacked by Evil Natural Water, a Dragon-level monster, who defeats all of them and badly injures them, knocking Okamaitachi and Bushidrill unconscious. 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.

- Air Blade (飛空剣, Hikūken, VIZ: Flying Sword): the technique taught by Atomic Samurai to him; by cutting the air, this technique creates a huge blade of wind.

- Okamaitachi's name is a portmanteau of okama (おかま), which means Homosexuality; kamaitachi (鎌鼬), the sickle-wielding yōkai who rides on whirlwinds and inflicts sharp, painless wounds; and itachi, often called Iaido (居合道), is known as a Quick-draw stance in the art of Bushido.
- The origin of Okamaitachi's hero name comes from Okamaitachi's heavy use of the Air Blade technique and being an okama. This confirms that Okamaitachi is in fact a male, although he is referred to as a female in dialogue.
- According to Bushidrill and Iaian, he has idol fantasies.
