At UA University, strength speaks louder than words. Y/N has spent his entire life chasing one thing: someone who could actually keep up with him. Then he meets Mirko. The fast, fearless, and absolutely infuriating rabbit. UA quickly gives them a nickname: The Rabbit & The Monkey. Neither can admit it, but they've finally found what they've always been searching for; a rival who refuses to lose. As competitions turn into late-night training sessions, heated arguments become effortless banter, and mutual respect slowly grows into something neither of them expected, one question remains... What happens when the person you've spent so long trying to defeat becomes the one you can't imagine living without? Because sometimes...The greatest victory isn't winning the fight. It's meeting your match.

In a world where power defines worth, Izuku Midoriya was born with nothing. No quirk. No potential. No future. At least, that's what everyone believed. Mocked by classmates, dismissed by heroes, and crushed under the weight of expectations, Izuku spent years clinging to a dream that the world had already rejected. By his final year of middle school, even he had begun to accept it... until the impossible happened. A system interface unfolded before his eyes. Stats. Skills. Missions. Gacha's [Dragon Ball System Initialized.] Inspired by the legends of Dragon Ball, the system grants Izuku something far beyond a traditional quirk. Every battle makes him stronger. Every technique learned becomes his own. From basic martial arts to godlike abilities, his growth has no ceiling, no limit, no rules.

When a dying alien transfers its armor to Izuku Midoriya, he becomes the new host of Tech Jacket 49-C-a weapon of galactic power. With the cold, tactical AI Helix as his guide, Izuku finally has the strength to be a hero.
