Asa-senpai, that's what I also was thinking about all the way, you're right on Gaku pulling a Madoka by becoming a nameless concept that cannot be percieved or remembered by anyone but one person, whose recollection of her being this particular human allows her to "invite" Gaku in her realm and interact with her, just like Rebellion!Homu. And if Urobuchi hasn't read this, that'd be just a coincidence, but that one of a greatest scale among literary coincidences of al time.
Moreover, what has been possessing my thoughts also is how this manga is not as much a quantum mechanic-inspired science fiction, as a philosophical study researching the concept of self. As in, self-ness, or Ichkeit, as Hiedegger called it. Thus, Manabu is most probably the Existenz that realised its Ichkeit, transcended the Sein ( being) but could not transcend other existences, as they all realize their own selfness through percieving Sein - and each's perception differs from the others, thus they are unique and on top of that parallel existences.
Aside from existentialism, this manga touches upon the problems researched by (post) structuralistic works, by trying to define the nature of individual perceptions of reality, but instead of tying it with language realm, explains it through physics.
