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


The majority of healing at the estate 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 Tanjiro, Inosuke, and Zenitsu recover after their battles on Mount Natagumo.
