You know, I think chunnifag hero has a point. They ARE NPCs, you couldn't get this contrived otherwise. Skyrim aah tier writing. There's no point to this story, our "hero" was summoned for reasons and thus far meanders about doing ??? with no goals, aspirations, or anything to define him other than a one note character.
I'd get it if the author wanted to a medium to draw ecchi, but at this point just draw hentai and be done with it.
