Inukashi

イヌカシ

Inukashi, also known as Dogkeeper, is one of the residents living outside No. 6. Raised by a dog, they now operate a hotel where they rent dogs to tenants, enabling them to stay warm during winter. They also participate in an information trade. They share a strong bond with dogs, especially the one that served as their mother, going so far as to attempt to kill anyone who insults her memory.
Although their relationship with Nezumi appears antagonistic on the surface, the two have grown somewhat closer since Shion's arrival.
Inukashi's gender remains ambiguous throughout the series.
