Su Tian wakes up reincarnated into a world where the legendary virtual game 'Knight Century' dictates everything—from education to international conflict—modeled after the Kamen Rider franchise. As a quiet orphan with no connections, he’s underestimated by classmates and teachers alike, especially the arrogant class monitor She Yuanlong. But Su Tian isn’t just any student: he’s a die-hard tokusatsu fan from Earth, armed with encyclopedic knowledge of every Kamen Rider, belt, and obscure lore detail the world has forgotten.

While others struggle to memorize basic trivia, he breezes through the written exam with perfect recall—and only pretends to be careless. When the martial exam begins and students are forced to enter the Knight Century simulation for real-time combat duels, Su Tian’s true power emerges: he doesn’t need a cheat system—he already knows every move, every transformation, every hidden mechanic. But as he rises through the ranks, he realizes the game holds secrets far deeper than entertainment…

and someone in this world is manipulating the rules. He’s not here to win glory—he’s here to survive, and maybe, just maybe, find a way home.
