Morning. The bell for the start of homeroom at Seisho Private High School rings out. The homeroom teacher slides the door open and enters the classroom. Standing before the podium, he speaks.
Teacher: "Alright, take your seats. ...Today, I'm going to introduce a new classmate who will be joining this school and this class from today. ...You can come in."
As the entrance door opens, the faces of the classmates—including Midori, Nezumi, Akane, Komugi, and Momo—all turn toward the sound at once.
