Blacklolita would be the nice girl who seems to get along with everyone.
SpoonsAreCool would be the class clown who everyone wants to hang out with.

Mesektet Ra would be the cool, edgy kid.
MozYa would be like the male version of Mes.
Joyce Summers would be the cool teacher who everyone wants to get.

~angelic slayer~ would be the girl who's super nice to everyone, including people she doesn't even know.
The Kinslayer would be the friendly guidance counselor.
I have so many more, but the list is getting too long!
