Musical-Chairs Fun with Baby Yukkuris
It's made of three parts: anko2315, anko2316, anko2317.
Summary (of all three parts):
A very long story in which an abusive Mister forces the seven children of a home-invading stray couple to play musical chairs with death as punishment for the loser. He promises that when one child remains, he’ll let her and her parents go free.
To the parents’ dismay, their children become increasingly scummy as they fight over the chairs for their lives.
Along the way, the mother Reimu sacrifices herself to make a deal with the Mister, but he weasels out of his promise.
In the final round, three koyukkuris are fighting for a single chair, and the one on the chair gets her skin ripped off by her two sisters pulling her braids in opposite directions. Mister declares the skinless koyukkuri the winner and presents her to her father before she dies.
Still desperate to save his children in any way he can, the father Marisa offers up his life in exchange for one of his children’s. Forced to choose between the two, he invites the little Marisa into his mouth, bites her in half to give her a quick and merciful death, and tells Mister that he has chosen the little Reimu to go free.
Now thoroughly scummy, the Reimu hurls insults at her father as she leaves, and as Marisa and Mister watch, Reimu ignores her father’s warnings, hops into the street, and is run over by a car.
Before she dies, Marisa can only despair and regret her decision to ever leave the mountains.
Despite all this, the Mister is disappointed by the lack of thrill he got from this abuse, and decides that abuse feels better when it’s a yukkuri that he’s cared for and raised himself.
