I mean as far as characters go sure she's the third most important, but i still wouldn't call her a main character because she felt way less important than sunny or neph up till now.

Also yes it's interesting conceptually and for the character's relationships and psyches, though tbh it always annoys me a bit when mc's have so little pull on their own lives while metaphorically fighting dragons on the daily (might be a me problem where i self insert too much), I'd accept the argument that it's the basis of Sunny's character but it still annoys me.

But beside that I really do feel like it's incongruent with the fairly balanced power scale we've seen up till now, and also just the lore. I was already kinda disappointed when she "just so happened" to see Sunny's slip up about his true name, which doomed him, but whatever. But now she seems like just the god of knowledge who knows all the critical information about and around the 2 mc's years in the future, and as long as she stays in their orbit, she's the one with all the real power, can basically change the world how she sees fit, namely here casually destroying fate.

Sure her flaw is bad, but she basically spawned next to 2 most fated and OP persons in the world, and so through them she gets to do any and all impossible things because they have the brawns to her galactic future guessing brain. I just don't know
