And then a helpful anon sings "mun~ch mun~ch happiness", and the Reimu chews, singing "munch munch" before she realizes she just ate her kids and starts screaming.
I wholeheartedly love yukkuri violence, but cute ones like this should really be left untouched to counter balance the ever growing amount of goru, feet burning and the oh-so-lovable screaming.
Just say take it easy and it'll reply, swallowing or chewing its children. 2-3 of them needs to be sent to the factory or they'll simply eat out the local environment. It should be the ones determined (after vigorous oniisan testing) to become annoying farm invading manjuus that are sent.
you got me wrong(or i wrote it in a wrong way), what i meant is, they are part of the ecosystem(if they are wild living yukkuris), so they shouldnt be taken out of it
They're an invader specie, like rabbits to Australia. The average spawn time is a week for three+ yukkuris. Growth to adult hood can be a month depending on food. Take out the yukkuris including the flandre types, they can't keep population down, some are even killed by defending yukkuris. You need to send in the kimemaru types that hunt and destroy yukkuris, even with oniisans the yukkuris still breed very quickly since they take time to torture only a family.
^The problem is that yukkuris are an invasive species, and as such disrupt the ecosystem. You yourself allude to them doing this when you talk about them "eating out the local environment", since, outside of remiryas and flandres, they don't have any predators and are free to breed at ridiculous rates and consume as they please, driving out everything else. The only thing that really keeps them in check are humans killing them in large numbers, and at the rate they breed, it isn't enough.
As far as the ecosystem is concerned, they're worse than pests; they're serious threats.
^ The Yuka type so far seems to help plants grow, don't want an over abundance of them as that might lead to favouring of plants over insects and other wild life.
There was one strip where oniisan tortured a family of reimu and marisa that don't invade farms or eat out the local environment. Regrettable action but had that family spread it, they would have been more acceptable. However they breed to fast to be vigorously tested for the good behavior yukkuris to be returned the wild. After certain stimulation the alice baby became the rapist and the flandre baby became the evil yukkuri eating type.(based on the yukkuri alice hardship artist) So it was probably the right decision to kill them off or simply remove them.
