Haru made a serious mistake when he laughed at Ryu. Now he has to find a way to make amends. Shimazu Haruhiro is having trouble keeping his demon half under control. Unfortunately for him its gained the upper hand and done some things that he now regrets: like making fun of Ryu then laughing at him. The damage has been done, now Haruhiro must figure out a way to mend the damage he’s done and get back into Ryu’s good graces or risk the demon part of himself taking over for good. Ryu’s been hurt by every man who’s ever promised him kindness and love, including the one he wants most in all the world: Shimazu Haruhiro, his sensei and lord. Made fun of and laughed at by Shimazu-sensei, Ryu’s had enough of such meaningless promises. It’s up to Ryu’s sister, Kazue to try and bring them together because even she can see how much Shimazu-sensei and Ryu want one another. But how can one girl overcome the pure stubbornness of a hard-headed brother while trying to balance the dangers of the road and their frequent battles with demons?
