1. Using strays (preferably scum) 2. Having at least two yukkuris for each session of abyuse. 3. Use of daily tools for abyuse 4. Making them suffer over a long time 5. Disposal according to society rules
Listing the merits of each, we then get an example of Mr. A. He came home to find a family of five (Parent Marisa-Reimu, Ko Marisa-Reimu, baby Reimu) in his messed up house. He quickly grabs a box and chucks them inside.
As he heats up a frying pan, he asks which one of them is the easiest. The parents know that humans are uneasy and tell their children to stay quiet, but the Koreimu answers, and gets her feet fried. Leaving her on the table, he asks for the next one, and gets Komarisa. He works his way through the family, until all of them are crippled.
He then asks which one of them wants sweets, but fearful, they don't reply until he shows them the carton of orange juice, saying that he will only give one. The baby Reimu replies first, and gets a tasty spoonful. As the parents beg their derisive child for some, Mr. A fills up a cup, and when the baby Reimu demands more, he drops her inside, where the family can see her trying her best to stay afloat.
He asks who else wants orange juice, but they just squeak. He picks the first Koreimu, and drops her on top of her little sister, who curses her sibling as she gets forced beneath the surface. Due to the healing properties of the orange juice, the yukkuris inside don't break up so quickly, suffering for a long time.
Next, he asks Reimu if she's pregnant, and goes to check even though she denies it. She struggles, and he purposely misses with a knife, getting her left eye and her tongue, blaming it on her struggling. That's when the Marisa interrupts and apologizes, saying she'll clean up the poop that her children did. Mr. A grabs Marisa's hat, and uses it to wipe up all the poop before putting it back on her. Because of that, she gets angry at her drowning children, and puffs up.
A quick slice into her cheeks with the knife causes Marisa to scream blubberingly. Mr. A concludes that Marisa cannot take it easy because of children, and moves to cut out Reimu's children. One of them breaks up, and he throws it into Reimu's mouth, forcing her to eat it. He crushes a few of the other babies by dropping Komarisa on them.
While Komarisa is staring at the crushed babies, Mr. A sticks one of the babies into Reimu's destroyed eye. Marisa screams, and he offers her a way out: kill Komarisa by turning the tap that would fill the box with water, and she would be spared. She hesitates, and he tells her to kill Reimu instead, switching the two around.
Marisa finally makes up her mind, and sends water down to end Reimu's life. Mr. A sets Komarisa's hat on fire, and she dies when it spreads to her body. Mr. A then points out that he would only spare her if she killed her child, not Reimu. That's when Marisa realizes that he never had any intention of letting her live in the first place.
Smiling, Mr. A asks Marisa. "Marisa, how would you like to die?"
The story then ends by saying that it's important to inflict regret and despair on yukkuris in abyuse, and asks everyone to come up with their own way of abyuse.
