Butterfly Mansion

The Butterly Estate is the manor that Insect Pillar Shinobu Kocho, Tsuguko Kanao Tsuyuri, and assistants Aoi Kanzaki, Sumi Nakahara, Kiyo Terauchi, and Naho Takada live in. The manor is often used as a recovery base for injured Demon Slayers.

History
The majority of healing at the estate is done by Shinobu Kocho, though there are also attendants known as Kakushi who run errands and assist in watching over the injured. On top of this, there are others who live in the estate that are not Demon Slayers, but offer training regiments to facilitate the recovery process and help the injured Demon Slayers reach top condition again. For example, Aoi Kanzaki creates a training regiment meant to help Tanjiro Kamado, Inosuke Hashibira, and Zenitsu Agatsuma recover after their battles on Natagumo Mountain.
