This is just a normal apartment that allow pet. On the first floor, a Reimu is body slamming the door and asked Mister to let her in. It's raining heavily outside and she feels uneasy because of it.
Reimu is a bronze badged pet.
As a bronze badge, she's good enough. She doesn't demand much from her owner.
But one night, he came home and only say one thing before throwing Reimu, "get out!"
Just when Reimu think she's going to die, a saviour came. Mister's younger sister who's Reimu is close with, came to visit her brother.
The sister is a balanced type who know limit of caring yukkuri so they don't easily turn into scum. She also quickly kill off the scums.
The brother... he's just an Average Joe who happens to have pet yukkuri.
After everyone calmed down, the brother starts explaining. Reimu want to watch TV while he's out. He had no problem with that at all. But there's nothing in the TV, so Reimu got mad and damaged the remote control. Not satisfied, she even tried to punish the TV, causing the new unit to breaks.
Thanks to that, Mister can't do the recording for a yukkuri show his sister has been waiting for.
With that, the sister is really mad. Reading into the situation, her brother already go to hide in the toilet, avoiding unnecessary problem.
She doesn't care anymore and throw Reimu out into the gutter.
After that, the brother and sister talk. She might still be able to get the recording from her friend, and her brother can still get an old TV and game console to watch the DVD.
Outside, Reimu slowly drenched in the rain and die.
