I WOULD FORCE MYSELF TO APP A GIRL SOMEWHERE but I actually would try Toki from Amatsuki and possibly Rufus from FFVII. Idk, it's been a while since I've had a ping to app a girl. If I did pick girls though, prooooobably...idk. Namie/Anri from Durarara and Lirin from Saiyuki.

A CHARACTER YOU WOULD APP IF THE SETTING DIDN'T KEEP THEM FROM JOINING (you know, like how kids wouldn't fit in Aather because of the level of trauma and such).
