Question I didn't understand, Futaba, Noriko and Sana, do they remember their "happy events" but prefer to pretend it was just hallucinations or did they really forget?
If the answer is yes to the first one, then they are already advanced, managing to maintain the memories of other dimensions and are strong candidates to reach the roof in the next updates, if Yes for the second alternative, it is already average because at least they experienced the supernatural world, but unfortunately they do not remember.
And now that Yumi is alive in the reset, is there any new theory that justifies which girls can join the apocalypse squad group?
