whoa yeah damn u rite
like asta and yuno could be twins born from the reincarnation of tetia's child(ren like she could have been pregnant of twins damn her belly was way too big for just 1).
that could explain why yuno was able to control his possessed body immediately because he got back his original soul which was reincarnated from a baby which couldn't control his consciousness.
tetia had wind magic and licht sword magic.
also when patri finally possessed william it could have been a trigger for asta and yuno to be born
nice theory
Sorr I dont understand asta's part
while I admit that Yuno could be Litches son I somehow believe Asta isn't the wizard king I think Asta is the demon itself whom was called upon by the elves and to stop him the wizard king sealed his magic in those swords and that's why he doesn't have any magic, But if they do go with the twin theme hmm it worked for Toriko and Starjun maybe here too...
What chapter is this again? Their past?
Litch and the first magic emperor were best friends. Teita's the sister of the first magic emperor. I support that Yuno is Licht's son with Teita and Asta's the son of the first Magic Emperor. And could be with an elf too - Licht's sister perhaps.
But it could be asta as well. That's why he doesn't have any mana because of what happened.
It's just, the first magic emperor became the first magic emperor is because he defeated the demon. So the incident with the elf came after that.
How many years have passed from that time? Time travel? aaaaaaagh (╯°Д °)╯╧╧
