Her outfit combines a long dress with a long-sleeved top. Two arches of hair sweep upward and divide at her neck, held in place by pins set to either side of her head, and a single bold spot marks each of her cheeks.

Personality

Though born male, she lives with the heart of a maiden. She shares a warm friendship with her fellow disciples Iaian and Bushidrill, yet her tendency to fall for good-looking monsters, and for attractive men such as Sweet Mask, wears on their patience. Sushi ranks among her great loves as well.

History

Atomic Samurai takes on pupils only after they clear his apple-cutting trial, a test that reveals how a person has lived, and Okamaitachi earned her place that way. Together with Iaian and Bushidrill she waits through her master's council meeting before the three storm the Monster Association. Inside they clash with Do-S and the mind-controlled mercenaries, briefly leave the fight to Sweet Mask, then return, and later pool their blades to bring down the Demon-level Devil Long Hair. Chasing Master Joe deeper into the base, the trio is finally beaten by Evil Natural Water, only for Pig God to swallow all three and spit them back out unharmed. During the Neo Heroes era they honor their fallen and look on as Atomic Samurai fails to goad King into a duel.

Ranked near the top of A-Class, she is a fierce fighter whom Fubuki reckons would sit in S-Class were it not for Sweet Mask's gatekeeping. Her prized Air Blade slashes the air into an enormous blade of wind, a technique Bushidrill likens to the work of gods, and she reads the flow of the wind to sharpen it further. Her senses run keen enough to detect killing intent and strike without opening her eyes.
