Enter the world of Tomomi Todoroki, a stoic yet fiercely protective hero-in-training with an explosive ice quirk and a sharp mind. Navigating the prestigious U.A. Academy alongside her twin, Shoto, Tomomi faces intense competition, family secrets, and the fiery rivalry of Katsuki Bakugou.

Two girls, Katsumi and Katsuko, identical in appearance but worlds apart in upbringing. One, a vibrant explosion of energy raised in Japan by her hero father, Dynamight. The other, a fiery spirit with a hidden artistic soul, growing up in France with her fashion designer mother. They've never known each other, until fate, or perhaps a mischievous summer camp, throws them together. What happens when two halves of a powerful whole collide, discovering a secret that reshapes their past and promises to ignite an unforgettable future?
