Ultimate Synergy | Bakugou x OC

Transferring into Class 1-B was supposed to be Kiari Hoshino's fresh start, a chance to master her volatile Kinetic Battery Quirk alongside a supportive crew. But when U.A. High initiates a mandatory three-week Joint Synergy Program, Kiari finds herself paired with Class 1-A's most explosive, hot-headed student: Katsuki Bakugou.

He thinks she's a loud, reckless extra. She thinks he's a arrogant hothead who needs to learn how to fight alongside a partner without blowing up the campus. But as their teacher-assigned evaluations force them to rely on each other's greatest strengths, they realize their Quirks make them two sides of the exact same coin. Can they refine their wild power into ultimate synergy, or will they level the training grounds trying?
