1st story: Wang Liu Mei, Louise Halevy, Saji Crossroad. 2nd story: hard to say, such deformed characters, Louise can be recognized thansk to the hair, male os probablu Saji, the other female I have no idea. 3rd story: Wang Liu Mei and maybe Setsuna?
I hate it when artists deform the characters to much it's hard to figure out who is who. Sigh.
