When a yukkuri says "eat up easy!", their body will be split perfectly in half, effectively killing themselves.
It's intended usage is for when a family is having starvation problems (usually due to being underprepared for winter). By performing eat up easy, a parent (or a big sister) can sacrifice herself and thus her children can survive off it's paste. Unfortunately this usually just delays their death by 1-2 days as the koyukkuris will have nobody to hunt food for them afterwards. Also worth noting is that eat up easy is generally the only instance where a non-predator yukkuri will tolerate cannibalism.
Recently eat up easy has also been used as a method of suicide, for then a yukkuri is undergoing extreme amounts of suffering (physical or psychological) and wishes for the sweet release of death. Unfortunately for them, an experienced abyuser will make sure to use anti-suicide preventions before performing long-term abuse so these sometimes fail.
A yukkuri will automatically split in half once it successfully utters "eat up easy!"
Intentions doesn't matter, a yukkuri who doesn't intend to die will still split in half if it's tricked to say "eat up easy!"
The yukkuri needs to utter "eat up easy!" perfectly and so even if the yukkuri wants to die if it can't utter those words perfectly then it will never split.
So, you want to perform a long-term abyuse but want to prevent your victim from commiting suicide? Well there's 4 ways to do it:
- choose a koyukkuri victim: Koyukkuris speak in a slurred manner and thus generally will never be able to utter "eat up easy!" perfectly
- make them slur: for adults, you can artificially make them speak in a slurred manner by cutting, stabbing, or ripping off their tongue
- make them mute: In rare cases, a slurring yukkuri might still be able to utter "eat up easy!" perfectly by accident. If you don't mind not hearing their wonderful screams of pain, muting them via sealing their mouth is a surefire way of preventing it.
- anti eat-up-easy drug: if all else fails you can just buy a drug to prevent it from mister factory
A good long-term abyuser will always make sure to prepare an eat up easy prevention method on top of the anti-anti-yukkuritis drug.
