Ryuuou no Oshigoto!

Sixteen-year-old Yaichi Kuzuryuu became the youngest player ever to win the prestigious Ryuuou title in professional shogi, only to fall into a humiliating slump almost immediately afterward. The pressure of being called an undeserving champion weighs on him until nine-year-old Ai Hinatsuru arrives at his home and reminds him of a promise he barely remembers: if he became Ryuuou, he would take her as his apprentice. Ai's extraordinary talent is obvious, but teaching a child who may one day surpass him forces Yaichi to look at shogi differently. As tournaments, rivals, and other gifted young players enter their lives, master and student push each other forward, discovering that protecting a title and nurturing someone else's future require very different kinds of strength.
