I almost called these guys the four horsemen... but they really aren't LOL
One day, these guys will get full character art, but for now, they're just busts. They are all minor characters in Someone to Watch Over Me.
In the meantime, I'll type up some brief bios:
Guignard (top right) - Childhood friend to Crissa, an Earth Magist (he uses plants to attack people). He's typically someone who is afraid of his own shadow and often needed saving by Crissa, but during his time in the Legion, he becomes a bit of an asshole (kind of the opposite to Forseth's personality).
Bertoly (top left) - Bertoly is an Ice Magist who befriends Guignard after being put into a unit with him. He's very friendly and very kind. (He initially has a crush on Crissa, but sort of backs off because he enjoys the friendship).
Gin (bottom left) - An Electricity Magist, Gin is all but nice. He's a brute, cocky, and self-centered individual who easily became the top of his unit from the get-go. He's often paired as Crissa's sparring partner because of the Water vs Electricity matchup. Gin befriends Guignard at some point and tries to become his wingman.
Asynthope (bottom right) - Asyn is a Poison Magist and a Second Lieutenant in the Alliance. He had previously been friends with Guignard prior to joining the Alliance, and remains such after he became an initiate. Asyn is typically a quiet individual, but is quite the force to be reconned with, hence his quick promotions.
