I wanted to make a mod that adds the characters from the shop as playable, since i'm terrible at drawing , i was wondering if there was a way i could Copy her from the game files and slap her into a mod

Update,

Good news, thanks to some help, i managed to get the sprites, 

Bad news, i'm not sure i'll manage to understand how faces work any time soon

Update,

Was mistaken, the guide Is very clear, still gonna take me a while between faces, dialogue, sprites (doesn't have chibi sprites), and skills
