its not that. theres a couple of clues that makes me think that its in the past, and that tokio sensing 2 ppl to come and rescue them is just a red herring or a misdirection.
1. the gun the girl MC has, was shown to be a prototype or something newly developed in either 1 or 2 chapters ago when they showed it off on some targets at the school. if its a brand new developmental product, then theres no way the girl MC would have gotten and held onto it for so long already.
2. they saw the symbol on the button/ring on the desolate building this chapter, hinting that the organization that used that symbol has been defunct for some time. you can make the argument that maybe it was an abandoned building or maybe it was just a side office and they moved somewhere else to redevelop but it certainly didn't feel that way, with the way the story has been progressing.
3. the fact that the MC and the MC in the school have the exact same face: why is that? that twin telepathy shit? its never been explained. but with the new information that the girl MC in the school had gotten pregnant, it seems (to me anyway) likely that they are leading into that the traveling MC in the present, is the son of the girl MC in the school.
