He then heard a voice, and he went further inside to find and he found this altar with a sword invented on stone.

He woke up to be in the presence of the Number One Hero of the world and The number one hero of France.

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.

Years ago, Japan faced a catastrophic event when mysterious dimensional gates appeared across the country. These gates were connected to a dimension known as Mato. However, through these rifts emerged terrifying monsters called Shuuki, which laid waste to villages, plunging the nation into chaos. Japan was on the brink of collapse until a miraculous discovery was made. In the attempt to fight the Shuuki they discovered strange peaches that could grant supernatural powers to those who consumed them. However, there was a catch: only women could harness these powers. This revelation led to a significant divide between the sexes, reshaping societal roles and prompting the formation of the Anti-Demon Corps, a specialized force tasked with combating the Shuuki. With the power of the Peaches, the women of the Anti-Demon Corps pushed back the monstrous Shuuki, forcing them into retreat and stabilizing the situation. Yet, the gates to Mato still opened intermittently, and those unfortunate enough to be caught within them were stranded in the otherworldly dimension. To address this ongoing threat, the Anti-Demon Corps established bases within Mato itself, dedicated to rescuing trapped civilians and maintaining a fragile defense against the ever-present danger. However, everything changed when armor individuals started showing up in Mato killing the Shuuki. If that wasn't shocking, they were also assisted by mechanical beasts. Their sudden appearance left the Anti-Demon Corps in awe and confusion. Who were these armored warriors, and why did they fight against the Shuuki? The mystery surrounding them sparked intense interest among the leadership of the Anti-Demon Corps, who saw in these warriors a potential game-changer a hope that could finally turn the tide in humanity's fight for survival.
