The next major arc will prolly feature nirei's FULL backstory with hints of sakura's. Then after maybe sakura's full backstory will be revealed. Finally, it will be suo's turn, which I'm guessing is close to the conclusion of the series.
(I have reasons and theories as to why, esp regarding the meaning of their names and the symbols used in the story, but its too long lol)
The other side characters backstories will most likely happen in the middle of, or after nirei's and sakura's backstory, but def not after suo's.
