Makabe Aizawa, is a beautiful woman who is perfect, good in any field and very striking from childhood. However, behind her very sweet nature outside, she behaves cruelly and like the queen with her younger brother named Haruto. Every day she treats him like a butler.

It seems that he has a desire to transcend the boundaries of sisterly relationships.<br> <br> (Source: Nekopoi and Has Been Translated)
