Man-etsu

Man-etsu was a Maho-tsukai.

Maho-tsukai
Man-etsu was a powerful shugenja, with shapeshifting magic, and the skill to bind an oni. She owned a serie of cursed artifacts, as an origami crane, a kimono embroiled with dragonflies, a fan decorated with a Hummingbird, and the infamous Butterfly Hairpins.

Fall in Love
Man-etsu took the guise of a geisha to seduce a Shosuro lord, intending to kill him and assume his position. She fell in love and gave up her dark magics to live with him, and they bore a daughter.

Death
Her oni escaped her weakened control, and Man-etsu sacrificed herself to save her family.
