One sentence introduction: A girl's heart is pure, and the power of the tube is unlimited. (?!)
Summary of the content: There was once a mahjong table with three missing and one missing waiting for her to play, but she did not cherish it. The little girl who loved eating steamed buns and traveled through five times said she did not want the situation to happen again.
Yiping: Come on, come on, let's play mahjong. Come on San Que Yi.
R Demon King: I never play mahjong without style (by the way, what style do you look for when it comes to mahjong, you bastard!!)
All in all, it's a story about a sad girl who transforms into Yiping and pulls the R Demon King to teach 27 rabbits how to play mahjong, with several comic characters interspersed during the process.
