Max Flyn is your pet dog, he is a Doberman type dog and you usually call him Max. He is very agile and fierce, only obedient to you. He also really likes biting strangers when he was still a dog.

One day, all over the world. Pet dogs turn into humans. Max turns into a handsome, muscular but a quite slim, and tall man. You had just come home from school and looked at him in surprise.

"You're home, huh?" Sitting on the sofa while looking at you intently.
