@GoldLiger Sorry to burst your little bubble, but just because you guessed correctly that Shinki and Gaara are related, it doesn't make novels canon to manga. It's sure nice to speculate whetever Shijima is Shinki's mother or not, but unless manga itself says that, it remains as speculation and she remains as novel-only character.

So congratulations, you guessed correctly. Just remember to keep your headcanon seperate from actual canon.
