Full Metal Panic! Short Stories Volume 3 — Shouji Gatou

Mercenary-turned-student Sagara Sousuke is here to solve any problems that might befall his new home front of Jindai High. He'll investigate a threat to a schoolwide sports tournament, play unwitting cupid for two lonely teachers, and engage in a cat-and-mouse rivalry against a lunchtime saboteur! With his potential love interest (and eternal wrangler) Chidori Kaname by his side, he'll also seek out the truth behind a haunted hospital and lay a trap for a fiendish after-school attacker -- who forces women's hair into ponytails! Life in Tokyo might seem like a circus sometimes, but ringmaster Sousuke is here to take control!
