Aritake Deigo has decided to move out and go live on his own no matter the cost. The reason for this is that he can no longer stand living with his family anymore. All he wants is to find a place to live a miserly life of self-loathing. While talking to an apartment agent, he encounters a strange blue-haired girl carrying a snake statue. When he starts hearing a faint voice come from the statue, he grows curious and touches it. A blinding flash of light ensues and he loses consciousness. Upon waking up, he finds out that he has been possessed by Lyssa, the Goddess of Madness. As a result, if he doesn’t live a life of happiness, he will be taken over by the Goddess of Madness and die!

Sakura Aki is a penniless high schooler who likes to cook and does other “unmanly” things. His grandfather and father are disciplinary on gender roles and beat up Aki everytime he does a thing that women would usually do, like cleaning. When his father leaves him absolutely broke, and with his grandfather realizing Aki’s “unmanly” flaws, he sends him to live at one of the dorms at an all girls’ school that he runs, a school where distinguished young ladies of the country attend, the Hanayashiki – Flower Estate-, to teach him a lesson. He meets Kitahiro Renge, a girl with un-ladylike manners and a meat loving obsession. An encounter that’s going to save Aki Sakura or just another problem in sight?!
