Life has been nothing but Ls for protagonist Koichi Hirose. Back in college, his first-ever girlfriend dumped him outright, and he ended up dropping out altogether not long after. Now he’s just trying to hold down a job to make ends meet, but for some reason, every company he joins goes under... So when his latest hard-won job vanishes overnight (again), he heads to Akihabara for some aimless daytime distraction... No savings, no career, no girlfriend. Where did it all go wrong? He sighs into the crowd, then to no one in particular— “...I sure could use a little love right about now.” In that moment, only feet away, Mami Mamiya is searching too.

And so the story takes a demonic turn. Tempted by fate and a mysterious invite from Mami, Koichi hitches a ride with her to her remote mountain home. Little does he know that he might never return...

After years of self-imposed isolation, a human male is just what Mami’s village needs to reacquaint with the outside world! Even touching succubi, however, can be lethal to the average joe... Not our Koichi, though. This boy’s built different. With the village’s blessing, let the succubus sessions begin...
