七都坂 慧生

"You can do whatever you like. I'm Hime-chan's ally."

The second son of the Nanatsuzaka family who owns a temple in Kyoto. He seems to have a blood connection with Seike; after all, he has eyes that have "received the blood of God". He seems fussy, but is actually pretty sold. He specializes in exterminating ghosts but can also deal with youkai.

He has a friendly personality, and has a habit of hugging. When he sticks to Kuro, it earns the anger of Mashiro and Yuu.
