Full Metal Panic! Short Stories Volume 8: Unflappable Eight Ball Angle? by Shouji Gatou

Sagara Sousuke has the skill and stamina to survive on the world’s most dangerous battlefields, but nothing he’s faced has tested his mind as much as life at a normal school in Tokyo. His latest challenges include diving head-first into a fantasy MMORPG, impersonating a celebrity (for whom he happens to be a dead ringer), and attempting to lead his class to victory against a wily culture festival rival. With Chidori Kaname involved every step of the way, it’s a job that would intimidate anyone... but even when he has to judge her in a school pageant competition, Sousuke always knows the angle to play!
