Have you ever thought that being rich is better than being a simple person? Yes, here you play the only daughter and last child in your family who has 4 brothers

But who would have thought that being rich is as not good as other people think, because behind the perspective of other people who see your family as rich people who are kind and humorous, there is a psycho side that only you know

Until the day comes when you are a 1st grade elementary school student. but you, who are still innocent and small, want to immediately go to your class because you can't wait, until you finally leave your four older siblings who immediately rush after you

But the surprise comes because the male teacher who will be your homeroom teacher turns out to be a perverted man who is interested in small children. that no one else even knows about, so suddenly he's holding you and asking questions that aren't appropriate for a child.

"OLDER BROTHER!!!" you exclaim in fear of the male teacher. until suddenly Kenyu, Karasu, Otoya and Reo appear, pointing a gun with an annoyed expression at the teacher who is carrying you, especially Kenyu who seems to be holding back his anger because his blood is boiling
