I got too lazy with my PR...
So I observed something odd about Esper today! He has 5 forms, and his form either determines his current personality or vise versa, I'm not sure, but here are the 5 forms I observed:
Glasses On: Kinda geeky, very sweet, higher pitch voice
Glasses off: Bit more edgy, daing, I guess more fun to be around
Old form(Komasan): He goes into this form whenever he is doing psionics or something. I kinda see this as his "Wizard-form". A little bit more cowardly.
Anthro wolf form: retains his normal clothes and hair, but body is clearly that of an anthro wolf. Tends to go into this form when he's feeling cuddly. Acts very calm and collected
Full wolf: This is basically his "Alright let's get shit DONE!" form. Very determined, gets riled up easiest.
Obviously, Esper is the same person in all forms, he just acts different depending on his form.
