STORY


College dropout Koichi’s life has been nothing but Ls, so when his hard-won job evaporates 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 kindness right about now.”

But in that moment, feet away, Mami Mamiya is searching, too. This shy she-demon is on the hunt for a human connection, and so Koichi’s story takes a supernatural turn...

Tempted by fate and an unsolicited invite from Mami, he hitches a car ride to her remote mountain abode. Little does he know he might never return. Or will he...?

Koichi is soon shocked to learn he’s in no ordinary village, but a succubine sanctuary, hidden from human eyes!

After years of self-exile and isolation, a son of Adam is just what this hamlet needs to reacquaint itself with the outside world. Demon contact, however, can prove lethal to the average joe...

Not our Koichi, though. This guy’s built different.

MAIN HEROINE


Mami Mamiya
Voice: Yuki Kitaohji

Mild and meek with a jealous streak.

For all her shyness, Mami’s powers are almost second to none. At first, she wasn’t too sold on the idea of befriending mortals, but for Koichi, she’s willing to make an exception. In truth, the two have met once before—at a summer festival years ago—and she’s been hoping to reunite ever since...

“Apparently, part of the plan was that I’d get to meet my father. If that was even possible... Guess I’ll never know.”
