My Hero Academia Crossover

In the darkest corners of Marseille, where hope sinks faster than a rusted anchor, an overdose should have been the end for Jean Valéry. But for this broken Navy veteran, death was only a doorway. He awoke with another soul burning within him—that of the Black Sea Alchemist, the failed guardian of Atlantis, whispering of ancient magic and the vengeance of the deep. Every corner of the Old Port is now his laboratory, every drop of polluted saltwater an ingredient for deadly potions and poisons. Fractured memories guide him, while a raw and dangerous alchemical power demands release. But Marseille is not only a haven for crime bosses. Deep within its murky waters, an ancient power has awakened, demanding accountability for the failures of his past reincarnations. To save the city, he must first seize it from the grip of the underworld. To atone for the sins of the past, he must become a monster in the present. This is not a story about the rise of a hero. This is a story of transmutation—how a broken man is melted down in the crucible of magic, malice, and destiny. The question isn't whether he will survive, but what he will become afterward: an unbeatable crime king, or a protector damned by the sea?

Now that the monsters are getting stronger, and the Darkness is awakening, the world would need to be saved again.

A man known as the Dark King, who had formed an alliance with the Demon King, was plotting to conquer the earth and turn it into the center of rebellion against the Celestial Beings. Fang Yun’s master then entrusted him with a mission to search for four sacred relics that would later be forged into a single sword of unimaginable power. With this sword, Fang Yun would one day face the Dark King and the Demon King.

Kai Gibson has always been ordinary—too ordinary for a city like Harborview, where power, influence, and fear rule every street corner. After losing his father under mysterious circumstances and struggling under crushing debt, Kai is pushed to the edge of survival. But everything changes the night he’s ambushed behind an abandoned mall and a strange surge of energy awakens inside him. With the rare ability known as Tactical Insight, Kai begins to see the world differently—patterns, threats, weaknesses, pathways to victory even when the odds are against him. Suddenly, the once-weak young man becomes a rising force in Harborview’s underworld. But Kai’s evolution comes with a price. Every step forward drags him deeper into a web of enemies: street gangs, corrupt elites, hidden organizations, and people he once trusted. Betrayals strike from unexpected places, and Kai learns that the attack that awakened his power wasn’t random at all—it was planned. Now trapped between shadowy forces that want to control him and others who want him dead, Kai must level up faster than his enemies expect. Each chapter pushes him through higher stakes: • deadly ambushes • shocking betrayals • growing supernatural abilities • strategic face-slapping comebacks • climbing from the lowest rung of society to a position of unstoppable strength As Kai climbs, he uncovers the truth behind his father’s death, the origins of his new power, and a hidden war brewing beneath the city’s neon lights. To survive, he must rise. To win, he must become more than human. And to uncover the truth, he must be willing to face the darkness inside—and the monsters hiding in plain sight. Harborview will remember the name Kai Gibson… whether it wants to or not.
