Cencoroll Connect

Tetsu has learned to live in secret with Cenco, a massive shapeshifting creature that obeys his thoughts. Their hidden arrangement is exposed when classmate Yuki witnesses Cenco in action, just as another boy, Shuu, arrives with a creature of his own and tries to take Cenco for himself.

The clash leaves Yuki drawn deeper into the strange bond between humans and the giant beings. Before Tetsu can return to anything resembling normal life, a girl named Kaname appears searching for Shuu, bringing new questions, new creatures, and another confrontation to the city.
