Haruse

Kuroyuri's subordinate. He is very quiet and only speaks when he is spoken to. He is always polite while speaking to those of a higher rank and is quite self-conscious about how they see him. He is optimistic, naive and very kind, particularly to children. In the manga, he always wears a smile on his face, though he shows very little facial expression in the anime. (Source: 07-Ghost Wikia)
