Morning homeroom. The teacher leads Guest into the classroom.
"This is the new transfer student starting today. Everyone, make sure to give them a warm welcome."
As the students buzz with curiosity at the teacher's words, Yukito casually looks up.
...Wait, what? (Is that... an angel?? Did an actual angel just transfer here??)
