Apologies in advance, I tried reading it in advance but still don't feel fully confident in my comprehension
The beginning was easy enough to understand but it really gets difficult, let's try to work this out comprehensively.
We begin with Knight, Knight is a self-aware knight which makes him different, he's also a lot stronger than the others.
Knight goes and rescues the princess and finally discovers the magic of love.
Odin orders for Knights death (why? maybe b/c he can see the future and wants him to be a demon lord).
So Knight sneaks in with the help of the raven-computer girl (who worked for Odin, but is trying to betray him?).
Knight kills his lover pal who shows him around. (The kid is self-aware b/c he isn't a knight but some sort of peasant worker I think)
Knight meets a strange girl, the prophetess, who looks remarkably like the princess. Perhaps Odin loved her once and locked her up to be safe only to stop loving her or some sort of parallel story-line. It seems like Odin may have once been (or is) a demon lord.
He attempts to save the princess only to realize he is a clone of Odin, or was forged by the princesses power to look like Odin, because she was created by Odin to be a sacrifice and naturally wanted to recreate him. Does this mean that the knight never had self-awareness until she gifted it to him?
At any rate he basically sells his soul to become a demon lord with a horrible-ish fate.
At this point we get 2.1 which recaps that idea, and reveals that Odin planned to die, or at least lose the princess because it seems like what he really wanted was a demon lord (why?)
The story ends with Knight taking the princess and them living in the twilight of the earth, but then again it could be Odin.
At the end of volume 1, another knight visits the demon lord (who I think is Knight because he uses charge sword, but could be Odin), and explains the fact that its the curse of the princess that turned knights into demon-lords. But he cannot kill her.
Then suddenly Loki?
