It's a bit complex but i will try to explain it to the best of my ability.
So the main point in recent chapter is the fact that the progress of Konoha's story have skipped a whole chapter/arc, because before solar eclipse came she have to met a certain character that have a knowledge about said phenomena, as the 2nd companion after Orochi.
And then, after meeting this char she met the 3rd prince of Albidus before going to Kingdom of Albidus as the 3rd companion.
we don't know for certain if 2nd companion is alive or not so i guess Iana ft Schwartz decided to skip the char and fix the thing that can be fixed right now, the direction of the journey, the reason for Orochi to join Konoha's squad and Sol's murder of Iana.
And to wrap all those 3 Iana came up with the idea to misled everyone to think that she is the Demon King, when in fact she is not. And guide them to the rightful step according to Dark History.(〜 ̄△ ̄)〜
Guys if I’m being so real I feel like I’m getting so lost rn in the plot. If anyone can explain what’s happening in this current arc with the mask that iana is wearing and how she’s interacting with her sister that will be much appreciated.
