Anon has an interest about yukkuri. Specifically, it's yukkuri's ability to inherit the instinct, basic knowledge and character of their parents. With this, baby yukkuri is arguably had higher specs than any other creature. Ever since they are born they can already speak, move and jumps.
Utilizing this trait, he want to create a better yukkuri. True, scum are born of scum, but wouldn't the same thing happened to the nice ones ?
For first experiment, he will try making yukkuri with genetically strong maternal instinct. For that he choose Reimu type.
First, Reimu is raped.
Yukkuri usually don't like children born out of rape. Even the Reimu type with strong maternal instinct is not excluded.
In the first stage, the parent Reimu and resulting baby Reimu and Marisa is put into an aquarium with two level of height. The food is given only to the mother and the children can only eat when feeded because they can't go up on their own.
Of course, Reimu never feed her babies.
Next, Reimu is put in a cage and food is given to the babies. Reimu can't eat unless the children bring it to her.
But as revenge of their treatment, the children never feed Reimu, instead they keep attacking their own mother until she dies.
Seeing that, the man took out Reimu in disappointment. His experiment is not progressing at all.
The children say they will be a good parent. They will raise their children, not like that shitty mother they have. This is exactly what he wants. By giving them harsh life, he will make the children grow strong desire to be a good parent, to the point they will even raise children born out of rape.
But those are empty words. This Reimu used to say the same thing when she's a baby, and she's already the 10th generation in his experiment.
Reimu argued, it's because she's raped. She want to have children with big sis Marisa whom she spent their difficult childhood together in the aquarium. If it's with Marisa, she will take care of the children, lick them, rub with them, sing with them.
Anon then asked if Reimu didn't realize it. The children are all Reimu and Marisa. She's raped by her own sister, if not there will be Alice children instead of Marisa. Reimu remembered, the Marisa babies' hat does looks like big sis Marisa.
He cut the Marisa's hair and give them hairband, then with strong aphrodisiac turns them into raper. He didn't use real raper Alice because he doesn't want their gene to be mixed in.
But his experiment has failed. Instead of making children with strong maternal instinct, it created children with strong adoration to child raising only. Without having any real care from their parents for generations, none has any knowledge left about how to raise their children.
Well, this is just an experiment to kill time anyway.
