Full Metal Panic! Invisible Victory

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.

This series is set about two months after the events ocurred in the Tuatha de Danaan at the end of the original series. Mithril becomes aware of a secret organization that has technology able to counter the ECS (Electronic Cloaking System) mode. This organization, known as Amalgam, also has "Black Technology", obtained from "Whispered" like Kaname Chidori, and like the other intelligency agencies, they intend to obtain more. However, when Sousuke's mission to protect Chidori is terminated by Mithril, all seems to be in place for Amalgam's plans... Like many of its fans know, it is based of the FMP novel "The End of Day by Day."

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. And while he struggles to continue living as a normal teenager, Sousuke also has to deal with protecting his superior officer Teletha Testarossa, who has decided to take a vacation from Mithril and spend a couple of weeks as his and Kaname's classmate.

A "director's cut" version of the first Full Metal Panic! television anime series.
