Yaichi Kuzuryu is a 16-year-old prodigy shogi player and the youngest person ever to attain the title of Ryuo (Dragon King), which is only awarded to the strongest players in the world of competitive shogi. One day, a young girl named Ai Hinatsuru suddenly shows up at his doorstep expecting to become his apprentice. Turns out, he made a deal with her at the Grand Championship game that if he won he’d become her coach, but since then he totally forgot! He reluctantly agrees to hold up his end of the deal, but his reluctance soon turns to excitement after he realizes her hidden talent for the game.
In Vol. 2, Yaichi begins secretly coaching another girl named Ai at the request of the chairman of the Shogi Association. However, things get heated when his apprentice Ai finds out!
