Seiji Aino Husbando

Seiji is a more-or-less level headed individual, trying to please all the women around him without hurting them. He, like all the others except for Guri, are minor angels as Guri made them all into a relationship together. As a result, they are all effectively immortal (But they still feel pain) and if Guri fails to do her job all the people connected to her this way will cease to exist altogether.
