VolleyGod System: The Last Benchwarmer

Kazuki Shōra (16), an ordinary high school student from the small town of Ikaruga on the outskirts of Osaka, harbors a secret: he's the eternal benchwarmer of his school's volleyball team. Brushed off as someone who "lacks presence" by his coach, and part of a team that keeps losing in regional tournaments, Kazuki has spent most games watching from the cold sidelines — earning him the nickname "Number 0" from the spectators.



Despite never missing a day of solo training, his chance to shine never came. Until one fateful night — the final night before the school's old gym is set to be demolished. Amid the silence of his intense, lonely practice, his body finally gives out. Just then, a transparent blue screen flickers into view.



“VolleyGod System detected,” the message reads, offering Kazuki a life-changing choice: “Do you wish to become a main player with abilities beyond human limits?”



Without hesitation, Kazuki accepts. Instantly, his first challenge appears: “Complete 1,000 jumps within 30 minutes. Fail, and access will be permanently revoked.”



This isn’t a game. It’s a high-level AI athletic enhancement system — a long-banned military-grade project from the Reiwa Cyber Initiative, shut down after the infamous “Human Limiter Collapse.” Every challenge is physically real. Failure means permanent lockout, and injuries carry lasting stat penalties.



Now, with just 7 days, Kazuki must rise from the bench or lose the system — and his dream — forever. Can the “VolleyGod System” transform the Last Benchwarmer into a true volleyball god? Or is Kazuki destined to return to the sidelines once again?



And most importantly… who's really behind this system — and is Kazuki the only one using it?
