Haikyuu: Serve of Destiny

Riku Amagami, a jaded 25-year-old prodigy in the corporate world, dies in a tragic elevator collapse. Just as he fades, a mysterious voice offers him a second chance—in the world of *Haikyuu!!*. Now reincarnated as a high school first-year at Karasuno, with no volleyball skills but the body of an athlete and a mysterious system in his head, Riku must navigate rivalries, friendships, and love—particularly with the elusive and beautiful Kiyoko Shimizu. As he rises through the ranks, he’ll discover that volleyball in this world is far more than just a game—it’s war, heart, and destiny.
