A man who hates house yu found a bodied house Yamame when spraying yu-cide between the furnitures. At first he thought this is a fairy, after all her shape resemble small human with puffy skirts.
He let the Yamame stay as his pet inside an insect case and give Yamame what she wants for her house. He still doesn't trust Yamame totally, but Yamame seems cute and nice, so he also want to let her take it easy in his house.
First it's Mister Bed, her own Mister Bed she take from her old house behind the furniture. But Mister throw it away immedieatly. It's the old socks he thought is missing for a long time and stuffed inside it are old tissues you don't want to know what he wipe with it.
Every night, he heard "yu... yuu..." voice, so he thought it's Yamame. But the next day, Yamame said she always sleep when it's dark dark. If "night" is when Mister is sleeping, then Yamame is also sleeping.
Yamame saw yukkuri behind the furniture, but Yamame will clean it up for him. It's been a while since Yamame had sweets sweets.
At first, Mister still hasn't connect the dots, but he soon understand when screams of yukkuri echoes in the house. He peeked inside and saw Yamame capturing and crushing the house yu making their nest inside.
As long as there's a hole, house yu will return no matter how many times you kill them. When he took Yamame into the box, he removed their natural predator.
After immobilizing them, Yamame stacked the yukkuri to a pile and sits on them. Then she came out from behind the furnitures with many white lumps. She tore open one of the sticky ball to show Mister, showing the face of a Reimu frozen in fear inside.
After that, Mister make it so Yamame can go out as she like from her box. He doesn't worry much because Yamame likes cleanliness. She won't make mess in the room or shit everywhere like house yu. Yamame also likes her home, so she stayed inside most of the time.
Thanks to that, the pest house yu is under control.
One day, Mister saw another Yamame and told Yamame about it.
Yamame told Mister she has to go. It's something told to her by her mom (or maybe she inherit from her paste).
Mister let Yamame go and feel lonely afterwards.
He has found the hole used by house yu to enter, but he never sealed it in expectation that Yamame will return again one day. He just kill the invaders.
When drunk one night, he called Yamame.
Yamame returned, but she's already weak. Yamame is happy to meet Mister, but now they have to part forever.
Inside her skirt, hundreds of small Yamame came out. They're Yamame's offspring and they know Mister.
After a while, most of the offsprings are gone their own ways. Only five is left in Mister's home and he let them stay in one of his empty cabinets. From there, everyday they hunt of house yu and other pest insects.
As he has promised, he will take care of Yamame.
