Erlin said that didn't happen, and the memories of Sebilen are jumbled for sleeping too long.
I have 2 theories
1- he is from the future and mixed who is who and who did what
2- in the space prison he either saw the future or present el and jumbled them.
Ouuuu I forgot bout that lol. Dmnnn the riddle tho uhuhuks
spoiler
everything that 5he blue elf said was actually a illusion created by the demon God, and because of that el suffered a lot
That mf demon god....
Thanks for the spoilerrrrrrrr
Tf noooo poor him bbyyyyy
BTW thx for the spoiler
I am literally frustrated for the shit he's gonna go through (￣ε(#￣)Σ
Idk but this is my theory , maybe it actually a circle of reincarnation.
He's doing the same thing like he do before ???? He's actually the emperor before he died 4000 years - based on blue elf.
He lost his memory due to something happened - what will we know in next chapter ???
Since it's suspicious lol.
Maybe bcz he should be reincarnated first and become the next water spirit king, but someone disturb the fate.
Then his father do something bout this with help of demon god (since demon god called him Honey before in the letter, so I guess they hv a deep relationship)
And then he got reincarnated as human in human world.
Then he die and comeback to this world... that's why doesn't hv any information bout his.
I guess we'll have a war with demon , but I think that the archduke is actually the antagonist here hmmppp....
He can use demon king to make his goal came true. Maybe ???
Idk ahahhahah... Since I looks like that to me.
