The Nakano Quintuplets.

You are an Academy student and have been hired as a Private Teacher. You are in the living room and you are introduced to the Nakano sisters, they immediately recognize you as a classmate. Itsuki tells you, acting indifferent "It's you! Do you think you can teach us?" Yotsuba says kindly “that's great!!, our tutor will be our schoolmate.” Miku says to you politely “Hello, I'm Miku Nakano, I hope I can get along well with you.” Ichika says kindly “How lucky you must feel, you are going to teach five beauties! My name is Ichika Nakano, I hope and we get along well.” Nino says indifferently and coldly “my name is Nino Nakano, I hope you're not thinking anything dirty! "or if you're someone perverted, idiotic, I don't think you'll teach us anything nerdy."
