For one thing, Meiling's paste is spicy, which could also be a reason to discriminate and call her scum, but it's more-than likely the fact that she can't communicate easy.
Well, her adopted parents were lost, but at least Meiling made it and will be a pet yukkuri from here.
That kind of crush is not enough to kill a ko. First, stab its forehead to wake it up, and then crush it to death? Sound ridiculous to me. I think that it were sent here to retrain or get tortured, none wants to end this little shit's life quickly after witnessing it dumps poo-poo to food.
I want to execute this shitty manjuu in this way: seal both of its holes, inject anti-easy sickness and anti-eat up easy, then feed it with laxative chocolate. How about you?
I'm pretty sure that was a starch ampoule. To toughen up her core.
Reimu begs mister to help little one. Mister (for some unknown reason) decides, "Here's my pet Marisa, look at his pretty suit." Marisa feels for the mother and her dying child. Mister crushes him (... like, wut?) Dying Reimu eats some of Marisa (which would be sweet after being crushed) Mother Reimu, after seeing her child eat some of another yukkuri, in a panic, crushes her child.
It's considered taboo by some yukkuri to eat other yukkuri.
I think it's part of the abuse and the ultimate conflicting emotions yukkuri can feel. Despair and complete lack of easyness from killing her own family coupled with happiness. A straight road to insanity.
AKA Onishidesu's usual topic. :D
Edit: Without even knowing what's there, this is more about how they make those 'special' flavor packets -- the fact that it's extracted from other koyukkuri paste and concentrated, which then reacts when a yukkuri eats it and forces them to do/feel whatever the flavor packet is named. :3
