The Evangelist had a lot more to do with how the Tokyo Empire was established than they previously thought. I think it’s safe to say this arc did a lot to flesh out the world of Fire Force. We know now some huge secrets that no one else was supposed to figure out. Back when we learned the Woman in Black was inside powering the Tabernacle it was safe to assume that the First Pillar was inside Amaterasu doing the same.

Hence why she manipulates the Adolla Link users, her anger at humanity for using her as a sacrifice is massive.

Time to find out what exactly the Holy Sol Temple is hiding.
