Full Metal Panic! Invisible Victory

Nine months have passed since a teenage soldier began secretly guarding a girl named Kaname Chidori. During this time, a military organization has effectively countered threats from a rival group, but this success has only intensified the opposition's resolve. A man named Leonard Testarossa visits Kaname and another individual, signaling the start of more aggressive actions, including interference with global communications. Because of her unique status, Kaname is a primary target for the opposing group, making it impossible for her to maintain a normal life at her high school.
