Shibuyaverse

There was no one Tendo Subaru despised more than Yamasaki Shoko, a gyaru bitch and his bully ever since elementary school.  When strange portals appeared across Japan, portending the end of the world, he finds an abandoned and crying Shoko sitting on a bench in the park on his way home.  Wracked with guilt, he invites her to his apartment to spend the night, and finds that he can't get rid of her!  But she's not unreasonable.  Shoko knows nothing is free, and she's ready and willing to pay... with her body.
