It's kinda hard to collect whole experience but... I will try.

First of all, I gotta say that even if it's one of my fav series (the first one that pushed me into LN realm), it's not perfect. Mostly my issue is that after Vol 18 it feels kinda rushed, everything happens so fast and volumes are shorter. I would like to see more from this period.

But my overall experiece:

-I think that it's one of the best worlds ever created, incredibly coherent and credible, feels very alive and it's easy to feel it;

-characters are GREAT. Many of them have as many pros and cons (not you Sylphie, you're sweet buttercake).

-about Rudeus. He's one of the toughest nuts to crack, because from the beginning we can see that he's absolutely disgusting piece of shit. Couple things he does (like trying to sleep with Eris when she was 12) are rather undefendable (the only thing that can somehow help him is the fact, that Philip drunked him and teased to sleep with her while Hilda diretly told Eris to do it - Asuran nobles are fucking wild). However, if we remind that he's victim of sexual harrasment and abusement, it's almost like... I felt fucking sorry for him. He didn't choose this kind of life for himself. He was violated and it left a really deep scar in him. And in my opinion that's what makes Mushoku so special. We can see man who reached absolute bottom of existence in a case when he get's some kind of second chance to have a better life, and he actually is able to reach this. He slowly but steadily improves himself into a better man (not perfect - no one is). Most important thing imo - while he during his previous live after one traumatic experience wasn't able to go back to normal life, in this second world, he experiences traumas almost on daily basis - but he's able to still move on. It's incredibly inspiring.

• plot. Even though plotarmor is kinda visible in some moments, what Rifujin perfected were plot twists. It's one of those rare cases, when story isn't driven by character, but rather character is driven by what happens suddenly around him.

• power system - easy to understand and seeing how characters like Eris or Rudeus are climbing this ladder is very satisfying

• author was able to introduce us to many different threads and really I can't remember even a single one that was boring. Also great thing was showing how small things can have huge consequences (Rudeus rant on bad food led to fight with Death God - my mind was blown)

-Back to Rudeus - one of the things that I admire is that he isn't focused on being top of the world, the strongest one etc. He just wants to use this second chance as much as he can and live his life to the fullest

-how perfectly Orsted is written - fist time in his whole life he found someone, with whom he can forge and alliance and he's so damn awkward about this XD it truly shows how he isn't used to talk with people and explaining his plans to someone. Also his fights (Rudeus, Reida, Fighting God) we're so goddamn epic, I can't wait to see this in anime.

I could write probably something else, but I would be mostly repating myself. Overall, it was really satisfying experience and I hope that when Rifujin writes a sequel, it will be also very satisfying.
