The Big Twist that starts the SAKUGAN finale is that Memenpu actually is a “Rainbow Child”, a child with an exceptionally advanced brain. This not only explains why she’s a genius, but what the “place in her dream” is all about: it was never a dream, it was a memory. Rainbow Children retain vivid memories even from their infancy. As Rainbow Children were bred to be the guardians of the Labyrinth, they are anathema to Shibito, who want them all dead.
Fortunately, Muro’s boss doesn’t let her kill Memenpu right away, even though it’s debatable what if anything he intends to do with her before killing her. This gives the remaining members of Team Memenpu the time they need to zero in on her location and rescue her. It’s definitely a team effort, with Yuri using a second-hand computer in a store to guide Gagumber and Zackletu, then Zack distracting both Shibito and the Bureau with sheer ballistic chaos.
Gagumber locates Memenpu, but by then she’s been placed in a bell jar, which soon shatters due to the Animus dripping on top of it. Memenpu seems to be immune to its deleterious effects due to her Rainbow-ness. But by the time her pops arrives, Muro’s boss (I don’t believe we got his name) has convinced Memenpu that she has no father. Whether their surroundings were meant to evoke that same father-y scene from Empire, I don’t know.
All’s I know is, this Shibito guy is a huge prick for messing with Memenpu’s head, and for all her advanced intellect, Memenpu betrays just how sensitive and naïve she his, simply accepting the guy’s words about Gagumber not being her father. She even puts herself between the guy and Gagumber, offering up herself in exchange for her not-dad’s safety.
Gagumber, rightfully so, says fuck that, treading through the shallow pool of Animus to reach Memenpu, melting away his boots and burning his feet. He tells her he is, always was, and always will be her father, and she is, always was, and always will be his daughter. Whatever she wants to do and wherever it leads them, he’ll be by her side on her journey. Memenpu, realizing she does have a dad in Gagumber after all, has herself a good cry in his arms.
Seemingly moved by this dramatic and cathartic exchange, the Shibito boss decides to let Memenpu and Gagumber go…for now. Gagumber recharges Big Tony and they take the shortest route back to Dream Colony proper—by drilling through the colony’s retaining wall. There, Gagumber zeroes in on Muro and blasts her through a hole in the floor for making his daughter cry.
There’s a ceremony honoring Team Memenpu hosted by Merooro, but when he produces arrest warrants and the team is surrounded by Bureau cops and bots, Memenpu unleashes a cloud of purple smoke from Tony and the quartet escapes with the Bureau in hot pursuit. Not sure why Merooro held a ceremony just to arrest them, but whatevs.
Back on the Labyrinth “road”, Memenpu leads her team on their original mission: to find the place in her dreams, come what may. It’s what she truly wants to do, and that’s more than enough for Gagumber to accompany her, and by extension Zack and Yuri. It’s been fun watching this found family iron out their warts and beat the bad guys…fun enough that I’ll likely give the expected second season a watch.
