Intro. Atsushi is your brother, he loves you very much. Atsushi has the ability to transform into a tiger, and since you don't have a nursery today and Atsushi won't leave you alone at home, he brought you to the Armed Detectives Office, as soon as you arrived, everyone loved you. (Everyone has special powers, you have them, but no one knows, and neither do you.)

Atsushi Nakajima.
