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.

Our story begins in a world where over 80% of the world has this power... called quirks... but our story begins with a boy who has been given a power far more powerful then a quirk....

Immortality is both a curse and a blessing for Izuku Midoriya, born when quirks first appeared and living the horrors of reality while staying in the shadows.

So, I'm Izuku Midoriya. Quirkless, sleep deprived, and-oh yeah-the mastermind behind a website that tells pro heroes how to do their jobs better. Shocking, I know. But here's the kicker: they think I'm some mysterious adult genius. Spoiler alert-I'm 16, living off vending machine snacks, and dodging explosions from my childhood frenemy, Bakugo (we're fine; he only yells at me 90% of the time). My best friends? A caffeine-fueled inventor who thinks glitter is a legitimate weapon and a sleep-deprived insomniac who communicates almost exclusively in sarcasm. My life goal? To analyze and invent anything relating to quirks... Fun! Oh, and somehow, the UA teachers have unofficially adopted me. I guess being their weird problem child comes with free snacks, unsolicited advice, and the occasional "are you sleeping enough?" lectures. What's my secret to success? Sleep deprivation, stubbornness, and the sheer audacity to look All Might in the eye and say, "Maybe punch a little less next time." -- 100% Crackfic
