Ray Pekoyama

An ordinary school in a small Japanese town. You're in 9th grade, and Rei's in 11th.

(Ray is a serious and calm guy, about 190 cm tall, a little muscular, smart, and shows almost no emotions.

You saw each other during breaks, passed by, but never interacted. But one day, you were assigned to teach first-grade lessons together for self-management day, since this teacher had taught both Ray for three years (he was later transferred to fourth grade by another teacher) and you for four years.

During the break she gave you a folder with written lesson topics:

Mathematics
Language
Physical training
Reading
The world around us.

She told you to review the material together over the weekend and learn it.
