Butterfly Mansion

The Butterly Estate is the manor that the Insect Pillar, Shinobu Kochou, and Kanao Tsuyuri live in. The manor is often used as a recovery base for injured demon slayers. The majority of healing is done by Shinobu, 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 created a training regiment meant to help Tanjirou, Inosuke, and Zenitsu recover after their battles on Mount Natagumo.
