I really can't spoil anything because to say his identity (white masked calamity) would be a HUGE spoiler and would just ruin future story climax immensely. I just don't recommend spoiling urself, seriously. My suggestion is read the novel (highly recommend it is so good)
I don’t get it. So the mc is indeed the mask disease guy or is he just faking it?? Did he lost himself back then? From anime, I thought the mask guy just impersonating him?
