wat

a dopple maybe?

It might be philosophical, or somethin'. Like Alice and an aging Marisa remembering the past?

yeah, its like a time spell or a flashback. the band on marlisa's hat is purple and here hair is white, so she must be an elder now...

I actually got the impression it was just Reisen in Marisa's clothes...

"That's how the days of youth flew past," hmm?

I think Alice and elder Marisa are looking at their daughter fly around.

If that was the artist's intention, adding Alice flying in the sky would have helped imo.

It's obvious Marisa aged seeing her hair which is not completely white but... from the way she stands and how her arms look, she didn't age a bit. Not a wrinkle or nothing.

to me, it looked like the one flying is Cho-Marisa
