After six years of separation, Himenokouji Akito reunites with his twin sister Akiko and they live together once more. However, in the meantime, Akiko had developed a serious case of brother complex, with romantic feelings for Akito.

But this is only the beginning of Akito's troubles, since Nikaidou Arashi, the student council president of his new school, vice-president Nasuhara Anastasia, and Sawatari Ginbei Haruomi, who followed Akito all the way from Kyoto, all move in with him one after the other.
