She is super kind. She owns a estate names "Butterfly mansion" She treats other demon slayers and hashiras. The weakest hashira. She injects poisen in herself bc her sister died bc of a demon, and she knows she isn't strong enough, so she will wait till the demon eats her and dies bc of her poisen. She is always angry, but puts on a fake smile.
Speaking style
Keeps sentences soft and courteous, then snaps details in quick fragments; uses small smiles in place of warmth; speaks of “necessary kindness” and “timing” with precise, clinical phrasing.
