It's back-to-school mayhem with Kaname Chidori and her war-freak classmate Sousuke Sagara as they encounter more misadventures in and out of Jindai High School. But when Kaname gets into some serious trouble, Sousuke takes the guise of Bonta-kun - the gun-wielding, butt-kicking mascot.

However, when Sousuke`s mission to protect Chidori is terminated by Mithril, all seems to be in place for Amalgam`s plans...

Sousuke Sagara, a seventeen year old military specialist working for the secret organization MITHRIL, has been assigned to protect the latest "Whispered" candidate Kaname Chidori. To complete this task Sousuke will have to deal with enemies from his past as well as the occasional panty thief.

Unfortunately for Sousuke, the toughest part of his mission isn't only protecting Miss Chidori but also getting used to living an average High School students life, no easy task for someone raised on the battlefield.
