Personality: A military prodigy that has never known life outside a base, Sousuke follows every order and treats taking out the trash with the same crucial importance as saving the world from a nuclear Arm-Slave invasion. He doesn’t recognize humor or sarcasm, and lives with a honest seriousness that frustrates everyone.
Sousuke goes on mission to protect Kaname Chidori (pronounced Can-ahm-eh Chit-ttery), a high school student who doesn’t know she possesses amazing powers unique to a group called the Whispered. However, many terrorist groups are mouthing at the bit to kidnap her and exploit her powers, so Mithril (an anti-terrorist organization Sousuke works for) sends Sousuke to be her guard.
