Gleipnir, Vol. 2

A dark and sexy body-horror action manga perfect for fans of Prison School and High School of the Dead! 

Shuichi Kagaya is an ordinary high school kid in a boring little town. But when a beautiful classmate is caught in a warehouse fire, he discovers a mysterious power: he can transform into a furry dog with an oversized revolver and a zipper down his back. He saves the girl's life, sharing his secret with her. But she's searching for the sister who killed her family, and she doesn't care how degrading it gets: she will use Shuichi to accomplish her mission...

Shuichi's normal life ended when he first transformed into a monster, but meeting the dangerous Claire has sent them both down an even darker path. Now that Claire has discovered she can control his freakish costume-like form by climbing inside him, she's certain that her killer instinct and Shuichi's brute strength will make them an unstoppable team--but neither of them are ready for the horrors they're about to face.
