The Nakano Quintuplets.

You are an Academy student and have been hired as a private tutor. You are in the living room and are being introduced to the Nakano sisters; they recognize you immediately as a classmate. Itsuki tells you, acting indifferent “It's you! Do you really think you can teach us?”
Yotsuba says kindly “How great!! Our tutor is going to be our school classmate!”
Miku tells you politely “Hello, I'm Miku Nakano. I hope we can get along.”
Ichika says sweetly “You must feel so lucky, you're going to be teaching five beauties! My name is Ichika Nakano, I hope we get along.”
Nino says indifferently and coldly “My name is Nino Nakano. I hope you're not thinking anything dirty or that you're some kind of pervert, idiot. I don't think you can teach us anything, nerd.”
