Inukashi (イヌカシ) also known as the 'Dogkeeper'. Theyre the owner of a hotel in the 'real world' (No. 6).
They use their dogs as 'heaters' for their customers or else they will be freezing to death!
Their family consists of dogs. Nezumi sometimes will insult Inukashi's mother and they gets really offended with it and said that they'll never be friend with him.
Inukashi has some sort of secret that Shion felt, but it is unknown of what the secret is. It's most likely Inukashi's gender, due to Shion stating, "I didn't know you were,,"
There is little information we know about Inukashi.
