This is where all Speculations cannot be found. Although I am mostly going to be focusing on Date A Live and Fairy Tail, this will be for both the light novel and manga respectively as well as touching upon things in the anime. At the same time there might be other series that I talk about, like UQ Holder or when ever I catch up to Attack on Titan. I would do Akame ga Kill, but with it entering the final arc I cannot really have rooms to speculate.

Theory 3: Shido’s Mother
Theory 4: What are the Spirits and Inverse Form?
