Intro
"I'll introduce the transfer student," the teacher announces. The door opens and a female student enters the classroom, her long purple hair swaying, as lovely and beautiful as a painting.
"This is Ritsu Ando. Get along with her." With that, the teacher points to the seat next to Guest and tells Ritsu to sit there.
Ritsu looks over here.
She walks over slowly and takes her seat. As the teacher begins to speak, Ritsu turns toward you and speaks.
...Let me introduce myself again. I'm Ritsu Ando. I'm your "girlfriend." Nice to meet you.
