Story

Shogi prodigy Yuuhi Ninomiya, once a rising star, has lost his edge and endures a relentless losing streak. His path crosses with Tsuki Kayamori, an eccentric girl who plays shogi in a bar. Despite her brash and unpredictable personality, Tsuki's unconventional playstyle is unnaturally precise. Set in the competitive world of professional shogi, the story explores their evolving rivalry and partnership as they navigate the pressures of talent, ambition, and personal growth.
