[New novel "What's Wrong with Playing Volleyball with a Lucky Charm?" No romance, highly recommended, daily updates. "Who Plays Volleyball Like This?" is a completed BL novel. 80% anti-piracy rate, anti-piracy period 72 hours.] Keita Takaraya is a genius, but unfortunately not a basketball genius. In his first and last official middle school game, he was crushed 10-96 by the Generation of Miracles, ending his basketball career. Watching his nephew, who had changed and declared victory was the most important thing, he felt increasingly distant from their initial love of basketball. After the game, a confused Keita Takaraya didn't know what to do. Just then—[Keita Takaraya, do you want to become a stronger person that no one can match?] [You possess volleyball talent!] The sudden system pulled the confused Keita Takaraya out of the abyss of failure and denial. Talent? Could he, who had been denied basketball talent, really have this potential? "Then what should I do..." Keita Takaraya wanted to know if only the strong deserved to love sports, so he accepted the system's training. ————————Aoba Johsai High School. Keita Takaraya diligently trained according to the system's instructions and even joined the volleyball club. At the orientation match, the upperclassmen expected another uneventful entrance exam, but… Keita Takaraya, claiming to be just a rookie, calmly stood in front of the net, tossed the ball, took a run-up, jumped, and finally—a full-force strike! The volleyball flew straight towards the libero like a cannonball. Seeing the unreceived powerful serve, everyone was shocked. "Are you a human gorilla?!" The King: "Weren't you supposed to be a completely inexperienced rookie?! I hate geniuses!" Reading Notes: 1. Contains original settings and OOC (out-of-character) elements. The protagonist is the squad leader's uncle. 2. A crossover between Kuroko's Basketball and Prince of Tennis, not just Haikyuu!! 3. The protagonist is a genius and will grow stronger over time. 4. The system is not very useful; it only provides the protagonist with a reason to play volleyball. 5. I am not a professional volleyball player, but I will try my best to include matches. 6. The protagonist will experience a ZONE-like state. The synopsis is serious, but the content is somewhat silly. Theme: Passion never ends, sports never stop.
