While staying with his cousin Genko, Harima is blackmailed into revealing his awkward past—including how he met Tenma and why he wears sunglasses. Little does he know, Tenma is sitting right behind him, hearing every word...

Tenma ends up locked in the gym's storage room and finds only one thing to eat: ultra-spicy curry bread! After surviving that ordeal, she finds herself facing a new one—alone time with Karasuma at the hospital?!

Hanai, smitten with Yakumo, volunteers his class to clean the school pool just to be near her. Chaos ensues as Tenma and the gang turn a simple cleaning session into an all-out aquatic battle.
