Tsuzumi Mansion

The Tsuzumi Mansion (の) is a large house controlled by Kyogai located in the south-southeast. It is the titular setting of the Tsuzumi Mansion Arc.

Description
The Tsuzumi Mansion is a large house with numerous corridors and different rooms. It was originally Kyogai's home while he was human and has been his base of operations since transforming into a demon.

Each room is controlled by Kyogai's Blood Demon Art in different ways. They can be flipped different directions or anyone inhabiting them can be transferred between rooms. While Kyogai's Blood Demon Art is active, running around the hallways of the mansion will only lead someone in circles.

Inosuke describes the hallways of the house as cramped and narrow while most of the rooms appear to be large and spacious enough for Kyogai's ability to be effective.
