Wow, and here I was thinking the Head Doctor was an illusion. But we've seen his face now so it appears he is a real person. These cliffhangers are killing me lol
Maybe it’s toru but something could “ trigger” his transformation. (Like the pursuit actives his stand and then divides him in two people)
Maybe it’s also Mitsuba father, remember that we don’t know much of her.
I think josuke it’s going to kill all higashikata clan
