Synduality takes a pause in its present-day narrative to tell two separate stories of yore. First up is a recording of Pascale both telling and showing Kanata, Mystere, and Noir the story of how she, a child of Amasia, went up to the surface to explore the real world with her Magus by her side, soaking everything up.
She didn’t believe Magus were merely computational dolls, but had the potential to become just as “real” as humans. She carried a journal containing a list of things she wanted to do, from tasting real grass to smelling the real sea and witnessing a real rainbow, all with her companion, student, and friend Mystere in tow.
When they located a signal up in space, Pascale had Mystere hack into it. On the same carrier wave Mystere used to access Histoire, Histoire send a signal back: Noir. Pascale never told Mystere, but Noir wasn’t just her safe mode alter-ego, but an independent entity, eager to learn and absorb information, albeit with no body of her own.
Pascale was pursued by Ideal, and in one scuffle, she is seriously wounded. Rather than give Mystere or Noir up, she has Mystere return to her unconscious safe mode in the museum where Kanata would find her several years later. The recording of Pascale regrets that she had to lie to Mystere, but urges her to see through the dream they shared of reaching Histoire. Mystere is understandably emotional, wanting so bad for the recording to be interactive.
As for Kanata, Pascale asks him to take care of her “girls,” and he fully intends to. But first, they locate Pascale’s grave under a great tree, and pay their respects. It’s then when Noir runs her hand down her chest and suddenly asks, “Where’s Ciel?”, heartbreakingly unaware that Ciel sacrificed her life so she could live. Like Mystere with Pascale, Noir lost someone precious to her in Ciel, but must keep moving forward.
The second story, is that of Macht, told while he and Schnee are just chilling in the present day. Macht, Licht, and Weisheit were all elite Coffin pilots given equally elite Magus. Weisheit got Ciel, whom he immediately started to treat and use as a mere tool, while Licht and Macht formed more human bonds with Mouton and Schnee, respectively.
Weisheit decided that the only way to reach Paradise, i.e. Histoire, was for all the youths to rise up against the adults who were administering them. That meant dirty work had to be done, and Weisheit had Ciel do a lot of it. Macht fell in line, as he believed in Weisheit’s dream, but Licht didn’t, and was imprisoned and marked for elimination.
There’s a clear parallel between Pascale and Licht/Tokio in that neither got much out of staying below ground in what remained of Amasia. They also felt that Magus were more valuable as friends and companions than as mere tools or weapons.
When Mouton sprung Licht, Macht had one more chance to choose a path: to go with Licht to the surface, or remain with Weisheit. We know which he chose, but judging from Schnee’s consistently forlorn tone both in the past and the present, you get the feeling she wishes he’d chosen differently.
Even so, once her “Lord” made his decision, she dedicated herself to him until the end, and he started donning his black mask. That mask symbolizes both his embracing of Weisheit’s darkness, and averting his eyes from the reality that it’s not too late to change his (and Schnee’s) path. He can still side with the good guys.
