A Returner’s Magic Should Be Special

I was actively reading a few years ago, but then stopped since it got dropped from MangaDex, and now I want to pick it back up again. I’m looking for a summary somewhere, if there is one, since I can’t invest the time to reread from chapter 1. Or if anyone’s goated enough to summarize some stuff for me, I’ll try to list what I remember.

S1 + Minor S2 spoilers below:

I remember a good chunk of what I read up to, it’s mostly the details of the world/character relationships and motivations that I struggle to remember. Basically season 1 is Desir returning to his student life, assembling his team, and then clearing their year one exam. And then I think I read the first arc of season 2? Something about the team returning to Romantica’s(?) home kingdom for some reason, and at the end Desir defeats some big monster that mask guy summoned using dragon magic but it takes a big toll on him. Then I started the next arc where they got on a flying ship or something but I’m willing to reread the start of that, I just need context up until the end of the kingdom arc.

Things in particular I’m struggling to remember:

-The overall background of the world and shadow worlds

-The magic system of the world, something about being two-ring or three-ring mages?

-The five people Desir knew from his previous life, their current status, and their current relation to him (Adjest is with him, I think he met with Zod and became his apprentice?)

-The different kingdoms

-Other background characters (I remember the blue moon party being a bunch of noble pricks, that’s pretty much it)

Anything anybody can tell me would be greatly appreciated! I really enjoyed the series when I was reading it and I’m interested in catching up now, especially with the anime announcement.
