For years, college dropout Koichi’s life has been nothing but Ls.

So when his latest hard-won job vanishes overnight (again),
he heads to Akihabara for some 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.
This pink-haired succubus is on the hunt for a human connection…

And so the story takes a demonic turn.

Tempted by fate and a mysterious invite from Mami,
Koichi hitches a ride to her remote mountain home.
Little does he know that he might never return.

Or will he…?

Koichi is shocked to learn that he’s in no ordinary human village.
He is now in a succubus sanctuary of sorts, hidden from human eyes.

Why Koichi?

After years of self-imposed isolation, a friendly human is just
what Mami’s village needs to reacquaint itself with the outside world.
The succubus race, 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!
