- Devil Summoner: Raidou Kuzunoha Major Character
Narumi was once an officer in the Japanese Imperial Army, but after being witness to the corruption of the military, he retired to become the owner of the Narumi Detective Agency. He is well versed in the ways of the world, and is aware of its many secrets, even having knowledge of demons and the supernatural. As such, he agreed with the Herald of Yatagarasu to take Raidou on as a part time junior detective while he worked secretly as the new Raidou Kuzunoha.
The Narumi Detective Agency only takes on the most unusual cases, where the impossible is all that's left, although generally he isn't the type to get his hands dirty, and would rather pass on all the leg work to Raidou. While on the surface he may appear lazy, Narumi cares a lot about the people and won't stand idly by while the citizens suffer. Should Raidou ever be in deep trouble, Narumi will try to help, even if it's far beyond his abilities.
