Haikyuu: I Grind To Beat My Genius Twin Brother

【You have gained +0.1 Grind Points for surpassing Yuuki in service aces.】 【Warning: Target is increasing training intensity. Adapt or fall behind.】 When I, Yuma Kikuzawa, got hit by Truck-sama and woke up in modern Japan, I thought I’d landed in the wrong isekai. No swords. No magic. Just... volleyball? But all hope wasn't lost. I was reborn into a sports dynasty with a twin brother, and even better—I had a cheat: the Grind King System. The mission? Surpass my twin in every aspect—training, performance, dominance on the court—and earn points to boost my abilities. Seemed easy enough. Until I realized something horrifying. My little brother Yuuki... is a volleyball monster. He spikes like a cannon, sets like a genius, and trains like he’s trying to kill himself—with a smile. And somehow, he’s still polite enough to call me "big bro" while crushing my soul every single day. Now, I'm stuck grinding harder than ever just to keep up. Every serve, every receive, every drop of sweat counts. Because if I can’t beat my prodigy twin, I’ll be stuck in his shadow forever. And this time around, I refuse to be second best. ___________________________________________ To read 40 advanced chapters you can visit my Patreon:"https://patreon.com/Excaliburs''
