In part 1 (anko3756), Anon visits his fellow abuser friend, a nutty female foreign exchange student named Mariisia Reemyun. She has an elaborate yukkuri clan set up in her yard, where four privileged families imprison ten other families in cubicles in a ditch and exploit them as "livestock-yus".
For a snack, one of the privileged Marisas demands that the "Food Number Four" livestock family give up one of their own. The family cries and resists, so Marisa burns the father's eyeball with a red-hot cigarette on a stick until the family gives in and puts one of their children into a box attached to a pulley. Marisa hoists out the screaming little Reimu and eats her alive.
Reemyun explains that she encouraged the privileged yukkuris to think of ideas, and then she gave them the tools they needed, but otherwise, they exploit the livestock-yus on their own. Most of them were resistant to the idea at first, but since they're former gold-badges slated for destruction that she rescued from the Factory, they're obedient to her and easy to convince. The livestock-yus are selected from strays that she captured in the park.
Next, Anon witnesses a "clothes-changing." A little Marisa and Alice tell their parents that they want new accessories (Marisa because hers is damaged from hopping, Alice because she wants a new one for Autumn). The livestock-yu children with the nicest accessories are kept separately and fed well. From that group, Alice and Marisa choose the two with the accessories they want. Their parents force the livestock-yus out, then father Marisa takes their accessories while mother Alice stabs them between the eyes with a toothpick. The little ones cast off their old accessories and eagerly take the new ones. The parents stomp and stab the livestock-yus to death, then dump their bodies into the pen of Food Number One family as food.
Food Number One is the oldest of the livestock families, and they've gone so insane, their pen has to be partitioned to keep them from eating their own children. After eating their meal, the parents start refreshing, while the little ones cannibalize each other. Disgusted, the family above decides that it's time Food Number One was culled. Some other privileged yukkuris carefully seal off their pen with a plastic board, then they lower in a hose and pump water into the pen. When the family has completely dissolved (except for their accessories), they open the pen and let the gloppy, creamy, bean-pastey water flow into the livestock-yu's main square as dinner for the other livestock-yus.
In the Food Number Two family, they're begging for bitter grass or garbage and demanding to be freed. The Food Number Three mother and child are madly gobbling up the dead-yukkuri glop while the starving father begs them to stop. In Food Number Five family, the father Marisa cries as she forces herself to eat the dead yukkuris, and her family cries and apologizes as they eat her feet. And in the Food Number Four family, who recently lost one of their little ones, Mother Reimu urges reluctant Father Marisa to eat and survive for their little ones' sake, in the hope that someday they'll be free. (However, the narrator says that Reimu's sense of self-preservation shows that she's scum.) Various dramas like these are taking place among the various livestock-yu families.
Anon asks Reemyun what she'll do with the privileged ones when the livestock-yus have all died out. She considers moving them into the livestock pens and starting over, or seeing what happens when they're are released into a stray clan in the park.
As the privileged yukkuris exchange happy declarations of love with each other, Anon and Reemyun go inside for tea. Reemyun announces that she's decided what to do...
Anon decides to spend the night. He and Reemyun have dinner at a restaurant, and when they come home, the yukkuris are in the middle of dinner. They've pulled out the Food Number Eight parent Marisa and four little Marisas. Parent Marisa screams that she doesn't want to die, while the little Marisas variously offer themselves for refreshing, say that this is wrong, beg for their lives, and gibber incoherently.
The privileged yukkuris work together to butcher the parent Marisa--shaving off her hair, peeling the skin off the back of her head, cutting off her head, and dividing her up according to each family's preferences--some like hair marinated in bean paste, some like the skin, some like smashed teeth mixed with bean paste. In Marisa's intact lower body, they discover a mammalian pregnancy, so they give it as a special treat to the privileged children, who eagerly gobble it up (and also rape one of the fetuses). Meanwhile, in addition to their preferred dishes, the privileged adult couples each take one of the little Marisas. One couple consumes their Marisa by sticking straws in her eyes and draining her dry.
At this point, the yukkuris see Miss and Anon coming by, so they all stop to politely greet her. Reemyun tells Anon that she enjoyed setting up this clan, but now that it's complete and she's shown it to Anon, she's bored with it. She speculates that part of the fun of making something is destroying it afterwards. Meanwhile, the yukkuris have gone back to their own affairs, carrying on an after-dinner rape of one of the livestock-yus.
Early the next morning, Reemyun assembles the sleepy yukkuris. She asks one little Marisa who claims to be the strongest what she would do if her family were in danger, then kicks part of the family into the livestock area. Bent on revenge, the livestock-yus start tearing parent Marisa apart, rape one little Marisa (even to the point of biting a hole in her forehead to rape), and chomp up little Reimu and spit her out, saying she tastes like scum. The "strongest" little Marisa begs Miss to save her family, but Reemyun tells her to save them herself like she said she would. Meanwhile, the mother Reimu has fainted in terror.
The partially-chomped up parent Marisa asks Miss why she's doing this. Reemyun asks her what she has in common with the livestock-yus--if Marisa answers correctly, she'll let her be one of the masters for a while longer. Marisa says that she's special, and the livestock can't take it easy. Reemyun says that's the wrong answer--the correct answer is that they were all chosen as samples for her experiment. Paradise is over.
The privileged yukkuris all start begging her to spare them. Reemyun offers them one of three choices: 1. They can leave now and go live in a clan in the park, or whatever they like. 2. They can trade places with the livestock--but they'll be fed, and allowed to have children, and the livestock will be forbidden to eat them. 3. The option Reemyun personally recommends--They can stay, and Reemyun will create a new level above them in the hierarchy. She might populate it with scum, or with bodied scum, or maybe with niceheads.
The yukkuris stop. They can't go back to living as strays, and considering everything they've done, it's unthinkable for them to go into the livestock pit. Only the third option is unknown. Their bean-paste brains begin imagining the best outcome--that they'll be elevated to the higher level later.
i know tis is old but why hasn't anyone notice that this girl looks like the bastard child of hakurai and kirisame i mean her first and last name are really close to reimu and marisa
