There are two families of Yukkuris living together, one Marisa-Reimu pair and one Marisa-Alice pair, both with about 4 kids each. The Marisa's are sisters.
One day anon comes to the forest with his assistant to do an experiment. The yukkuri family greets him without any sense of danger and then begin asking for sweets. The man tells them that there are sweets right there, but the yukkuris look and can't see any. Of course he is talking about the yukkuris themselves. They start calling him stupid and moving towards him but suddenly a deep yukkuri voice shouts "stop moving" and the yukkuris confusedly stop.
Anon has had his assistant use the special item which anon has invented, a microphone that mimics the sound and reproduces the ultrasonic waves of Dosumarisa and can be used to brainwash/control yukkuris.
They yukkuris start freaking out because they cant move, and anon gets his assistant to separate the two families. They still haven't realized that the humans are the ones controlling them. Using the machine he forces them to be quiet.
He then goes on to bring out a whole bunch of uneasy looking stuff. One is a rough wooden log covered in splinters with a crack going through it. Calling out a komarisa, he gives her a sweet and asks if she can go through the tunnel. "Impossible! Marisa will get ripped apart! Funfun!" "Its okay if you get ripped apart, just go through it" He orders the little komarisa to go through it. She screams at her footsies to stop as she crawls towards the crack.
He then let's the yukkuris talk again and they futilely tell the komarisa to stop. She is unable to and squashes herself into the tiny gap, causing her to pop and lose one of her eyes in a fountain of anko, dying painfully. One of the little koreimus passes out.
When she comes to, anon is drilling the yukkuris on what just happened. They still do not realize anon is the cause and think Marisa did it to herself. Again he tells the yukkuris that they are sweets, and if they want sweets they should cannibalize themselves. Angry at the things he is saying and that he isn't giving sweets, the yukkuris demand he leave their easy place.
He orders all the koreimus but one to eat the parent Reimu. He also gets the partner Marisa to eat its komarisas.
