[@Lmpkio] Once upon a time, I thought I could make Miyu relevant. But then I learned the golden rule of the nexus "The Strong get Stronger". There was no room for someone starting weak to advance fast enough to catch up. And I also learned that all the cool unique powers I had in mind for her to learn were actually just basic level angelic magic that everyone in my faction had access to, but didn't use because they had better stuff. There was no way to become the "Angel of Unity" in the same way that Juno is the master of Gravity and Space, or Ciel is the master of Stars.

Also, as I said last time, it's foreshadowing. If you want your proper appellation, make your own summary.
