"Yuuuu! At last Marisa has gotten the ULTIMATE home, ze!
Trembling with emotion, Marisa took it easy in the home she had just obtained. It was a cardboard [box] completely lined with styrofoam and covered with a stabilized waterproof sheet--an insulated all-weather house. With this, she wouldn't feel the cold winter ground or be burned by the summer sun.
But with so many desirable features, too many yukkuris had their eye on this house.
"Yugiiii, go away, zeeee! This is Marisa's home, zeeeee!"
Even if she wanted to go out hunting, her house was constantly being targeted, so single Marisa continued to hold down the fort alone and unaided.
And then, still [at home], suffering from starvation, she took it easy forever. If she had had a family, she might have been able to have them watch the house, but this house was too small for a mate.
In this way, the ideal home continued to be occupied by an ever-changing series of residents.
Hmmm, this somehow makes me recall all those home invasion stories on which to some degree it is hinted that the home invasion is a typical thing between yukkuris, but the problem being, them not realizing their "logic" doesn't apply to human's easy places for well known reasons.
Now it makes me wish for a story this is developed as some sort of discussion between the home owner and the yukkur invader, pointing out the difference of situation, leading to the conclusion of "Sorry yukkuri but human homes don't work like your yukkuri homes, even if unprotected physically, there are many "invisible" forces protecting it."
