Full Metal Panic! Vol. 7

Lunches are disappearing and clothes are being torn to shreds in the halls of Jindai High! Sosuke decides to take the investigation into his own hands, but he gets sidetracked by the discovery of his own hidden talent - synchronized swimming! This underwater soldier can impress everyone in his swimming trunks, but how will he measure up to Kaname's grandfather, an ex-military man with twice the experience of his granddaughter's protector? Sosuke might be acing it as an undercover student, but the jury's still out on his military performance in Full Metal Panic! Volume 7.
