When Oishi told me his theory that the Sonozaki family would promise to look after Satoko if Satoshi were to move away, I thought that idea was ridiculous.
But once I thought about this idea more carefully, it seems this theory is not so farfetched after all.
For one, Houjou Satoko is now living with Furude Rika once she became all by herself. Furude Rika is also not just a little girl herself either. She is the current head of the Furude family
gosanke. Furude Rika is also under the protective custody of the head of the Kimiyoshi family as well.
Even though the Sonozakis would dare not keep a child from the Houjou under them, they did keep their word as Houjou Satoko is being cared for under the two gosankes.
Given how much the they were denounced as traitors during the dam protests, it is unbelievable that a Houjou family member would be under the gosanke's protection.
It's as if only Satoko was given amnesty for the crimes that the Houjou family had committed.
Satoshi-kun was never given any amnesty. Why only Satoko?
