Sudou

Sudou is a bully and leader of his gang of dirty teens who attends Lights gamou prep course. Even though he breifly appeared he did have some lines. He went up to another student and started harassing him for 20 yen to go to the arcade with. Light thought about killing him but then decided not to due to the fact if its someone to major the cops might keep it secret for a while and he needed a result right away to prove if the death note worked. Then he just said its not worth it because a guy like him nobody's going to notice. He first appeared in chapter 1 in the manga and the first episode in the anime. He has possibly been seen in minor cameo appearences while light's in school.
