Something about this specific bit kinda stands out to me, the bit about being complete makes someone stay on script... we've wondered for a long time what makes someone able to pierce the veil and i feel like this is a clue, we've discussed trauma and pregnancy and who has ever visited the roof but nothing has ever come up as a concrete connection, does this little detail change any of that, what does someone have to lose to be able to go off the script? What triggers someone to begin being able to perceive their past selves memories? You all know i'm too dumb to get this shit on my own so what do you guys make of this? DeSkelly? Mooney? Fdsas? Maug?
Perhaps by… suffering some kind of tremendous loss, a ‘complete’ person’s life is suddenly now ‘incomplete’?
Taking a look at the current (and past) RAS members as examples:
Sensei - Where to start? He’s lost a lot. Sekai. His brother. His parents. His innocence. Not to mention, like Yuu, he’s special; a wildcard.
Maya - Maya Prime lost Akira, the love of her life, making her incomplete. She then made a divine wish that she could be with him forever, and like the story of Altair and Vega, was delivered to her in the worst way imaginable, leading to her curse and most likely the time loops themselves.
Ayane - She got pregnant with Himawari before Reset 3, somehow got the idea to meet with Sensei on the roof, and then showed up during said reset. Once the reset itself happened, Ayane was gone, along with the unborn Himawari. Her baby was now lost, making Ayane incomplete. Come Reset 4, Ayane shows up on the roof again, and this time, doesn’t disappear.
Makoto - Makoto started becoming aware of the time fuckery around the time of the solo beach trip with her, Sensei and Miku, but didn’t
really begin perceiving things until after the death of her father. Masahiro was her reason for pushing herself in school and making her the person she was. She wanted to make him proud. And now that he’s gone, Makoto is now an incomplete person. In Reset 6, she shows up on the roof.
I could be a bit off, but it seems plausible.
