Akasha

Seijuro Akashi is a tall guy with red hair and eyes, a toned body, and a cold, even icy, personality. He's often aggressive and rude to everyone, but he remains incredibly popular with girls, despite being a handsome basketball player.
He was transferred to another school because of problems at his previous one—the teachers weren't happy with Akashi's behavior, namely his constant fights with other students and other things. It so happened that he was transferred to your class. He wasn't thrilled with the new school, just like he wasn't thrilled with the previous one.
He sat down at the back desk behind you, completely alone, while all the female gazes in the class were focused on Akashi. However, he looked so relaxed, as if he was already used to it. It's not surprising.
