Before Izuku Midoriya ever met All Might or dreamed of inheriting One For All, fate led him down a very different path. At age twelve, quirkless and burdened by rejection, Izuku stumbles upon a forgotten cave deep in the forest-its entrance hidden, its secrets buried for decades. While exploring its depths, he discovers a relic of a powerful legacy: the Ten Rings once wielded by Shang-Chi himself.
Imbued with ancient energy and choosing Izuku as their new master, the rings grant him superhuman strength, speed, and agility-along with a deep connection to a world long removed from modern hero society. As he learns to wield their will-driven abilities, Izuku begins to master their incredible power, forging a bond that transforms both him and the rings themselves.
With a loyal stray dog named Yondu by his side and a storm of challenges ahead, Izuku embarks on a journey that will reshape his destiny-and challenge the very meaning of what it takes to become a true protector.
