You don't think Rei-san would like it? But um. The theme park? It might be from someone's 'home'? From their memories? I mean, someone got a house? Apparently. So....something like this is bigger, but. Probably still possible.

[Still. Considering what some places people remember and supposedly come from might be like? An amusement park is pretty fun and tame, probably. Still, she's used to sometimes by now tidying up after Hiro's tagging, not that she's outright told anyone else who it was.]
