I'd feel bad for the little Reimu, but I actually find Patchy's method of teaching her kids kinda funny. Teaching through example without risk to the students... GENIUS!
K, can we get some juice here now? Little Reimu is taking this badly.
My rather more sinister interpretation is that Patchy captured the koReimu specifically to be the guinea pig. The koPatchy and koMarisas are her own kids, and she wouldn't want to risk them. It would explain why koReimu is crying out for Mwommie to save her if Patchy isn't her mother.
I actually wrote a little short story inspired by this... seeing as the Marisa told Reimu to be obedient, I imagined that the Reimu was a kidnapped pet and eventually mister came looking. I threw it away after I wasn't satisfied with it, though.
I don't think that it will survive, i mean, burning pain may actually mean it's a form of spicy mushroom, if something like that exist, and spicy = sure kill for yukkuris.
I dunno if i can approve of this method of teaching, oh well, they are yukkuris, doing something like this is not weird or out of place, actually, now a days, is weirder or strange to see yukkuris being nice and taking it easy.
Damned yukkuevilution. . .it's because of you we don't have nice things! TT3TT
you know I think I saw this sceen in a story, except a pissed off yuuka mother showed up, killed the mother, beat the crap out of the father and stuck all of there children on sticks
