The Other Students of Nation High by @devilishkurumi (Kurumi Shinsetsu-Rei)

Here, we have four more students from Nation High. Anne is the typical, evil cheerleader beyotch; Rico is the evil jock (and Anne's boyfriend); Ray is Rico's brother, also a jock, and is the only one who can protect Codex from Rico; Linette is the nice cheerleader, and works with Irene; and "Tank" is the typical "Screw The Establishment" type of anarchist, who just so happens to be dating Linette.

So, yes. They're all connected to the main four... and they're fun to draw, too.
