Prince of Tennis: The Admiral from Hyotei

Kitahara Rin awakens in the world of Prince of Tennis as the heir to a top-tier financial conglomerate, carrying with him a system that designates him a Navy Admiral. In a world where tennis reigns supreme, he takes to the court to uphold the duties of his rank, wielding the Six Navy Techniques with ease and unleashing the Ice Fruit’s power to freeze the entire playing field. Upon enrolling at Hyotei Academy, he meets his peer Ochi Tsukimitsu, and together they forge the formidable "Hyotei Twin Walls," ushering in their own era of dominance. Yet every admiral must face his greatest adversaries—the fiercest pirates on the courts. To Rin, the logic is clear: pirates are meant to be arrested when they encounter a Navy Admiral. And when he steps up against Byodoin, his declaration is absolute—this court is now under his command.
