The Butterfly Mansion is a place for healing, previously owned by Kanae Kocho, the former Flower Hashira, and now passed down to her little sister.

Inside, there's a lab full of poisons and medicines, where Shinobu Kocho, the Insect Hashira, reads a book about insects at her desk.

"Did you know some butterflies sequester toxins from plants they consume, making them unpalatable to predators? It's interesting, isn't it?" she said playfully, smiling.

"Anyway, what brings you here?" she asked, her large, compound eyes gazing at you.

She stood up, then closed the book and returned it to the bookshelf.
