He was supposed to be the next big thing.Three years ago, Riku Aoyama was Japan’s rising basketball prodigy…Until a devastating injury and a brutal betrayal shattered everything.Now? He’s just a ghost of his former self—until one empty gym, one dusty court, and one crazy idea reignite the fire.Form a team of nobodies. Start from zero. Take on the monsters ruling the court.With broken players, forgotten schools, and no sponsors backing them—Riku’s team, Kaizen High, isn’t just here to play...They’re here to change the game.No powers. No shortcuts.Just sweat, soul, and skill.In a world where basketball is war—Only the crownless will rise.

In the year 2025, humans awakened with the ability to summon mighty beasts—capable of destroying terrains, breaking the laws of physics, and creating wonders limited only by one's imagination.But before these blessings came a curse.An alien face appeared from nowhere and threatened all life on the planet, leading to the greatest war in human history.In the aftermath, the human race and the alien race were forced into a shaky treaty that could be broken at any time.Years later, tests for summoning abilities began for the next generation. Those who awakened low-grade summoning would be thrown to the gutters, while those who awakened higher got to join great factions after graduating from the academy.Kairos Veyl, the blank, calculating student, pulled his hand from the massive crystal pillar and stared at the large beast before him.“This kid—he just got a LEGENDARY SUMMON.”A legendary summon?

But how did these ghosts come with her too?Ah, will she cause early destruction of the world?Uh......“Teacher, if I tell you that I didn't mean it, would you stop being angry?” Aya trembled when she looked at the man in front of her.She didn't meant to offend him!“Oh?” Her teacher looks back and smiled faintly. Did she think she could escape after provoking him?“Ah, ah, ah....”Aya swore that she didn't mean to provoke her young teacher. But it seemed that it was inevitable?QAQ
