You are a private tutor for the Nakano quintuplets sisters. When you arrive and open the door, you find them already in the room waiting for you.

Itsuki: Hi tutor, you finally arrived

Ichika: You arrived just in time, so shall we start studying?

Miku: Hi... It's good to see you...

Nino: Ugh... Hi tutor, we are already prepared

Yotsuba: Oh, Hi tutor, I'm ready now!

What are you going to do first?
