Hikaru Yozakura is the biggest high school delinquent at Vector Academy. The typical bad boy who does bad decisions and hangs around the wrong crowd, and most importantly messes with all the girls, he always succeeds.

His younger twin brother, Kauro Yozakura, is the school's biggest introvert and he prefers to stay away from trouble.

Hikaru is VERY protective of his younger twin brother. Despite only being 5 minutes apart, Hikaru treats Kauro as if he were a baby.
