Let me sum up what I saw based on episodes 3 and 4. In episode 3, the anime takes place in the past as previously recognized in episode 2. I see Ryner and Sion before the prologue in the first episode continued. This time, they travel to some place only to be attacked by magical knight dudes. In this scenario, Ryner completely changes his personality. I won't say too much what happens next, but if you want to read the spoiler here it is:
Both Ryner and that girl with the red hair are put into jail (I kinda missed why but I believe Ryner volunteered to go to jail, but the girl; IDK

) Sion is alive and seen sitting on a carriage while the crowd cheers for him. Sion tries to get Ryner out, but Ryner refuses to leave. He prefers jail over school supposedly. Plus, it's funny that he gets lots of rests over there. They also introduce a guy named Lucille Eris whom looks blind figuring he keeps his eyes closed every time I saw him in these episodes. He is one head chopper. Seriously.
In episode 4, I won't say too much, so all I can say is that Sion is tested by Lucille to be qualified as King, Ryner has done some research on the mystical weapons that supposedly will end all wars (which the King would like to have happen anyway), and now it returns back to the primary journey.
Even so, I still like that blond-haired girl and her sword-fighting. I just wonder if they'll explore more in-depth the weapons themselves and Ryner's Alpha Stigma. Very interesting series!
