anko3694: "Shtway Weimu Wantsh to Become a Pet Yukkuchi"
A (rather self-centered) little stray Reimu, suffering in the heat of summer, wants to become a pet yukkuri and take it easy. She asks her mother how she can do that, but Mother Reimu doesn't know. Mother Reimu decides they should ask a pet yukkuri.
The next day, they ask a platinum-badge Yuka-nyan taking a walk with her female owner in the park. However, Yuka-nyan is trained not to speak to strays, and anyway, she doesn't want them interrupting her flower-viewing, so she ignores them, angering the Reimus. Yuka-nyan's owner asks her if she's all right, and she says she's fine, just a little unable to take it easy at being spoken to by dirty strays. The stray Reimus get even angrier.
To show the Reimus what a pet yukkuri should be like, Miss asks Yuuka-nyan what makes her take it easy, and Yuuka-nyan says she feels easiest when Miss is taking it easy. The Reimus don't get it, and they rant and rage at Miss. Yuuka-nyan asks if she should punish the stupid scum yukkuris who've insulted Miss, but Miss says she's fine, and suggests they go home to eat toast and honey. Miss's parting words to the Reimus are to tell them that a pet yukkuri must be able to make others take it easy.
The Reimus gloat that since anyone can take it easy just by looking at cute little Weimu, she's sure to become a pet yukkuri.
Several days later, a dead parent and child yukkuri are dumped in the park's yukkuri disposal bin with their flap-flaps, hair, and teeth yanked out, their eyes gouged out, stab wounds and burns all over them, and their faces contorted in agony. And whether it's that Reimu parent and child or not, nobody knows.
