Shuuichi's smell pulls him toward people the way gravity works, he has no choice, no control, and every instinct screams at him to stay buried instead. The series knows exactly what it is: fanservice as narrative permission slip, letting you watch him transform into something that shouldn't exist while the mystery of what he actually is unfolds underneath. By episode four, the action sequences stop being excuse and start being consequence, and you realize the show spent its early awkwardness building something genuinely strange.

Shuuichi Kagaya is a high school student in a dull small town who hides a strange secret: at times he turns into a monster, a furry dog-like creature with a zipper down its back and a huge revolver. He has no idea where the power came from and wants nobody to find out. One night he transforms to carry a classmate, Claire Aoki, out of a burning building, but he loses his phone at the scene. Claire tracks him down, and when he denies everything she shoves him off the school roof to force a transformation. She takes a photo and uses it to pressure him into sharing what he knows about monsters, which turns out to be very little. Claire is hunting for her sister, who also became a monster and killed their family, and she means to use Shuuichi to find her. They soon learn that others are chasing answers too. The series is an action mystery with supernatural and ecchi elements, adapted from a seinen manga by Takeda Sun.
