桧山 太陽

Born on October 19, 1989.
He's a talented student that wasn't supposed to attend Sakura Junior High School, but because he had a fever on the day of the entrance exam, he failed it and was forced to attend Sakura Junior High School instead. He has lost sight of the reason for going to school due to bullying during his first year, his family environment, and the pressure of those around him, and as such has stopped attending school. Despite not attending school, he still has the highest grades in class, so he has remained a shut-in in his room without any problems, and he only communicates with his mother through emails. He's email pen pals with his childhood friend and classmate Tsukiyama Misaki, and they get along well, even walking to school together when possible, and Taiyo sometimes shows signs of having special feelings for Misaki.
