I found a Flandre in the yukkuri shop that had the bow and halo from when yukkuris die in this game, yet this one was alive and healthy. There's also a cockroach-yu Alice in the foreground right next to the wasa Reimu.
I've got a screen capture of a Reimu giving birth on a suii.
If those winged halo accessories granted flight to a yu born with them, it would be much more interesting (especially abyuse). And get rid of the melodramatic acenscion to heaven cutscense and music.
