There's always the scent of Tea in this place. 

A character fascinated by monsters. 

While he is a therapist,

He's only agreed to see those who want his help. 

In the past he had tried to help someone who didn't want help

but it appears it only drove them further.

Away from that if you can find him, he buries himself in medicinal baths and the smell of incense is present on his body. 
He seems to be a nightmare plagued by a mysterious illness.
No one is quite sure what kind of physical ailment it is...
