Class 1-A is expecting a normal training camp. Or at least as normal as anything involving U.A. can be. Instead, they're introduced to y/n: a sixteen-year-old international exchange instructor from China with a résumé that sounds completely made up. Honorary military sergeant. Disaster relief specialist. Decorated youth leader. Hand-to-hand combat instructor. Apparently, governments trust them. Pro heroes respect them. And for reasons nobody can explain, adults keep saluting them. The problem? Y/n looks like an ordinary teenager. A very ordinary teenager. A very ordinary teenager who apologizes when people walk into them. Class 1-A quickly decides there's no way the stories are true. Then they watch them disarm a combat instructor in less than ten seconds. As the summer camp continues, the class begins discovering that behind y/n’s medals and reputation is someone carrying far more responsibility than any teenager should. Meanwhile, Denki Kaminari finds himself increasingly fascinated by the mysterious teen everyone seems to admire. Unfortunately, the more Denki learns about y/n, the harder it becomes to tell whether he wants to be their friend— or hold their hand.
