Shadow Rising: My Hero's Awakening
18 parts Ongoing Description
Izuku Yagi was born the twin brother of Izumi Yagi, Japan's "Chosen Successor" to the Number One Hero, All Might.
She inherited One For All.
He inherited... nothing.
Quirkless. Weak. Forgotten.
While Izumi trained under the Symbol of Peace, Izuku was left to watch from the shadows, told over and over that he could never be a hero.
Until the day a Gate opened in Musutafu.
Until the day he stepped inside - and died.
And then... woke up.
Now, bound to a mysterious System that turns his life into a series of deadly quests, Izuku gains the ability to grow without limits. His strength, his speed, his skills - all can evolve beyond the boundaries of any Quirk.
But with power comes enemies - both human and something far worse.
In a world where heroes and villains battle for dominance, the real war lies beyond the Gates, where monsters, shadows, and ancient rulers play their own deadly game.
Once the weakest twin, Izuku will rise - not as a hero blessed by the light, but as the ruler of darkness.
And this time, the world will remember his name
If you want, I can also make you a detailed character profile for Izuku Yagi as Shadow Monarch, including his abilities, personality changes, and relationships in this crossover. That would make the worldbuilding way stronger.
