Izuku and Shinso are twins to the powerful villain, AFO/Hisashi, a hero killer, Stain, and someone who's considered human but at the same time, considered a Nomu, Kurogiri/Oboro.
Two people have heard of the twins, Inko and Toshinori Yagi. Inko was not capable of having children of her own, which is probably why she originally stole the two twins. Izuku would stand up for his twin, despite his twins' protest.
When Stain woke one day to his sweet angles gone, he whimpered loudly, making his other child, Tenko, come in and rush over to him. He asked what was wrong and his papa told him in a shaky voice that his twins were gone. Now, Tenko, was upset and vowed to find them.
When the others found out, they went to look for the twins. That search will never stop until those two were found. Izuku had lost his spark when he was ten. He was also very innocent unlike his brother. He tries to not infect his brother with it though. When the twins were about 14, Toshinori's old friends were coming. More specifically, Hawks and Midnight.
When Midnight and Hawks get to the house, they were hit with an omegas scent. And they were just at the door, not inside. Hawks knocked, a male omega who's spark was gone answered. That was already a red flag for the two heroes.
What happens when Izuku and Hitoshi find their mates? Hitoshi wanting his brother and himself out. What about when Izuku saves a hero from a Nomu? The said hero he saved, one of his mates? What if the hero tried to follow him but lost track of him and his scent? What will the villains do when someone took down the Nomu and realize that they seem familiar to the said villains? What if Izuku saw his other mate in the shadows one night? What if he got away from that soulmate as well?
In a world where heroes are the law-and execution is their justice-being quirkless isn't just a disadvantage. It's a death sentence.
Izuku Midoriya once believed in heroes. He studied their moves, dreamed of saving lives, and clung to the hope that one day, he'd prove the world wrong. But hope is fragile... and the world is cruel.
Betrayed by his idol. Beaten by his peers. Abused at home. When society's "protectors" make it legal to kill dissenters, Izuku becomes their perfect target. And when the people he loved most turn their backs, he runs-bleeding, broken, and ready to disappear.
That's when he meets Shigaraki.
Offered food, shelter, and something more dangerous than a quirk-purpose-Izuku is reborn as Null, a shadow in the dark with a vendetta against the very society he once worshiped. With the League of Villains at his side, he will expose the rot beneath the hero's smile, dismantle their false justice, and watch the world that rejected him burn.
In this brutal reimagining of My Hero Academia, alliances are fragile, morality is a weapon, and the line between hero and villain no longer exists. The question isn't whether Izuku will get his revenge-
It's whether anything will be left once he does.
