Three Threads, One Weave

When two unexpected transfer students step through U.A. High's doors-Aurora Hinode, bearer of a light-and-dragon quirk that bends dawn and shadow, and Hiccup Haddock III, a brilliant inventor who commands scaled skies-Class 1-A is turned upside down. Assigned to the same team as the explosive Katsuki Bakugou, what starts as clashing egos, bickering, and impossible training missions slowly hardens into something far stronger: an unbreakable trio.

But as they fight side by side, share secrets, and heal each other's scars, the lines between partnership, friendship, and something deeper begin to blur. Will their bond settle into a tangled love triangle... or will they learn that their hearts were always meant to weave together, three souls beating as one?

An MHA × HTTYD cross-fandom AU full of heroics, banter, found family, and a love that refuses to fit into just two.
