Is it worth it?

So I’ve finished the anime, and I’m craving more.

It’s not often I watch something and I’m sad about it or left wanting more, Castlevania, Castlevania nocturne (a blessing the second season came out and now I’m sad again) but like those are the only 3 shows that made me feel that way.

So the question is, is the manga worth it? I’ve read from other Reddit posts it isn’t as detailed as the LN, is the LN worth reading? I’m really wanting more and season 5 just started being animated in September of 2024 so I can’t imagine it’ll be done for quite awhile.

Question 1: I heard that Ainz found out who brainwashed shalltear and he got super angry and the emotional suppression couldn’t keep up with his emotions. I would love to know if this is in the manga or LN.

Question 2: Where to read both the LN and manga for free preferably.

I don’t care about spoilers I just love the lore of the series and would love all the super cool moments, but mostly would love to know where to read it.
