蝴蝶忍

Butterfly Ninja, a character in the manga "Demon Slayer: Kimetsu no Yaiba" and its derivative works, is the insect pillar in the Demon Slayer Corps. Butterfly Ninja's parents died at the hands of evil spirits, so Ninja hated ghosts very much since he was a child. The former Butterfly Shinobi was a competitive and angry woman, but after her sister Kanae was killed by a ghost, Shinobu began to smile all the time like her sister.
