In a world where mythical creatures reign supreme, the Bakugou and Todoroki families are two of the strongest Dragon clans in existence. Katsuki Bakugou, a fierce Fire Dragon, and Shouto Todoroki, a rare Fire/Ice hybrid Dragon, are caught in a tale of rivalry, self-discovery, and unexpected companionship. As political tensions rise between the Dragon lands and other territories, alliances are tested, friendships forged, and love blooms in unexpected places. With a looming threat that endangers all kingdoms, everyone must unite to protect their world.
Adding complexity to their bond, Katsuki and Shouto discover that they were part of an arranged marriage pact between the Bakugou and Todoroki clans since birth. The pact is set to activate as soon as Katsuki, the younger of the two, turns 18. This revelation forces them to navigate their feelings amidst their rivalry and the growing threats.
