Armed with a hidden "Professional Tennis System" that makes him a genius in mental power tennis, Tatsuki plans to keep his abilities secret and enjoy a peaceful school life. But when he alone perceives a looming health crisis threatening the radiant star he admires, everything changes. To protect the light he looks up to, Tatsuki must emerge from the shadows—even if it means revealing his true power.
