There is a Reimyu koyukkuri in a city yukkuri clan. According to what the clan members say, her parents "went to the park to get Refreshed! so they can "give little sister for the Little One" but on the way they got run over by huge Suii and take it easy forever". Anyway, Reimyu understand one thing, her parents are not returning anymore.
Reimyu then stay with her mother's mother, an old Reimu who can't hunt anymore and got food shared by other clan members. Little Reimyu is stupid and messy, their neighbour Alice who share them food doesn't care anymore.
A thing Reimyu loves is to hear her grandmother's story. When grandma Reimu is still her size, she live in a big room, having sweets sweets everyday and have a Mister Human who let her take it easy.
Reimyu loves this story and dreamed to have a human slave one day. But no human came to pick her up, even though she's so cute.
Finally, Reimyu decided she will go to the human instead and found a human in the park.
The human hear Reimyu asking to be taken as pet and picked her up. On his hand, Reimyu saw another Reimu all bruised. The bruised Reimu is a shithead, but he think Reimyu is just stupid. This human hate Reimu yukkuri.
Back in the clan, Alice asked grandma Reimu to stop telling her story. She's no longer a pet and those stories could make the kids get the wrong idea about human.
But grandma Reimu herself still wondered, when her Mister Human will come to take her back.
