The Ryuo’s Work Is Never Done! Vol. 6 (Light Novel)

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. 6, Yaichi is able to defend his title as Ryuo and becomes the youngest in history to be promoted to 9-dan. Moreover, his two apprentices become Women's League players. Everything seems to be on the up, but then New Year’s arrives and brings tons of new problems with it!
