A short post for this since apparently it managed to take the 1st place of Kono Light Novel ga Sugoi! 2017’s Best Light Novel category.
Ryuuou no Oshigoto! is a comedy and shogi light novel written by Shirow Shiratori (author of Nourin) and illustrated by Shirabi. Three volumes have been released so far and it seems to be positively received in Japan so far.
“Yaichi Kuzuryu is the youngest shogi champion in history—the ‘Ryuuou’.
And this is Ai Hinazuru—a girl who asked him to become his disciple.
Being too young for his title, Yaichi is going to revive his shogi through a passionate disciple…
Wait, Ai-chan is 9 years old? She is an elementary school girl! And… is she going to live with Yaichi? All night until the morning? What? Officer, can we have you here, please! A comedy about shogi-holic live-in disciple.”
Will put this on the list next time.
