The Fourth Great Ninja War had finally ended. Peace had returned to the shinobi world. Heroes were celebrated. Villains were defeated. And for the first time in years, Kakashi Hatake believed he could finally relax. Unfortunately... Fate had other plans. A mysterious dimensional distortion appeared during one of Kakashi's missions. Before he could react, the legendary Copy Ninja was swallowed by a vortex of space-time. When he opened his eyes... He was no longer in the Elemental Nations. He was in a world where nearly everyone possessed superpowers called Quirks. A world known as My Hero Academia.

Haku Yuki was supposed to die on a bridge. Instead he woke reborn into the Yukimura clan, heir to a quirk that lets him slip through mirrors and bend cold into blades. Bound by duty to an arranged alliance with Shoto Todoroki, Haku must learn to move like a weapon and think like a shield. At U.A. he trains under watchful teachers, weathers whispered rumors, and faces a world that prizes power over mercy. When the USJ attack shatters the classroom's safety, Haku's calm precision and Shoto's volatile strength collide with villainy and sacrifice. Between tea ceremonies at the estate and battles that demand everything, two heirs discover that protection can be taught, but courage must be chosen. Quiet, strategic, and dangerous in equal measure, Haku must decide whether to be the clan's perfect blade-or the kind of hero who refuses to vanish.

"What... are you?" "Tired, mostly." You were the youngest graduate of the 104th Training Corps and the most promising officer of the Survey Corps - not that this mattered in the end. At fifteen, you die fighting to stop a worldwide genocide known as "the Rumbling". You thought everything would end there for you. But somehow you found yourself in a reality thousands of years in the future: a world of quirks, heroes, and villains. After everything you've been through, how will you react when given the chance to take on the alias Y/n L/n, and attend hero school with a group of slightly problematic teenagers? Will a soldier ever fit in during an era of peace? Is this future without titans - the one you died to create - what you imagined it to be? (under constant revision)

Mankind faced one of the bloodiest wars ever witnessed not only by the galaxy, but by the universe itself. For tens of thousands of years, humanity had lived in what many believed to be a perpetual utopia, a golden age born from technological wonders beyond the imagination of lesser civilizations. Alongside their ancient allies and former rivals, they built a vast alliance that spanned the entire galaxy and reached heights that seemed impossible. But even such a civilization was not eternal. From beyond the known dimensions came an unknown and endless race of abominations that consumed every corner in the universe. One by one, stars went dark, galaxies were reduced to nothing and entire civilizations that had lived for millions of years were wiped away. After 100 years of desperate war, the surviving remnants of humanity and their allies made one final attempt to escape extinction. Using a device forged from the combined genius of human and xeno technology, they tore open reality itself and fled from the tendrils of the Great Blight that unraveled creation itself. But an incident happened. Instead of merely crossing into another universe, the refugee ship was thrown through infinite dimensions until it arrived in a new multiverse, one whose laws and systems were completely foreign to them.
