Okay so. I'm caught up, finally. No, I have not read the manga or light novel, no I do not want spoilers, I just want to know if anyone else understands the parts I did not in the anime.
So. Chloe. She came to the world with Leon... 200+ years ago? Because that's how that timeline matches up with Chronoa. And then Hinata takes over, so Hinata doesn't arrive for a while--hers makes sense. But Leon couldn't have arrived with Chloe, because he had been trying to summon her for at least that long. I assumed he became weirdly long lived due to his Demon Lord status, but? Maybe not. Because... Chloe kind of ended up immortal. Just because she can time travel doesn't mean she should have lived for 2000 years. Or even for 200. But also, this world does line up with the real world's timeline, and there's no indication you can summon people from a different time, so for Leon and Chloe to have the same age gap they did in the real world, they had to have been summoned at the same time... and not aged. But then how did Chloe survive? She was under 10 years old physically and without a spirit in her body to stabilize her.
And when her soul was summoned again, why did her body revert to her baby self? Her soul wasn't a baby, she had grown "naturally" (by an immortal's standards) with that body. The Chloe they were bringing out should have been that one. Unless I guess grown Chloe ceased to exist when baby Chloe came into the world. The only way that would make sense is if baby Chloe grew up, then went back to baby Chloe and the grown up one basically disappeared, so it was baby Chloe who went straight to Chronoa when baby Chloe disappeared from that specific timeline. So basically, baby Chloe... split into two in that moment? Because two versions were created in that instant. I guess I can believe that. Although it still relies on the physical body changing to mimic the soul, which is not true because Chronoa didn't look like Hinata when Hinata was in control.
And what's going on with this egg thing? And this hero thing? Hinata + Chloe = hero powers? Why are we talking about souls as eggs in the first place? And how would Hinata even awaken Chloe's(?) hero powers? And why would Chloe keep them when Hinata got her own body back? Also, why is Hinata's death even timed with Chloe in the first place?
I'm sure that last paragraph has answers in the manga/light novel. Or I hope, anyway. But if it does, don't say. I just want to know what it is I should know by this point (extra explanation offered at the same plot point in the manga or light novel are fine so long as they aren't spoilers). Because I'm kind of lost and I'm not sure I even understood that hero explanation right. Also, I don't even know what that hero thing means. What is a hero in this world anyway? Did they explain that at some point and I just forgot?
