I don't know if you count this as a book but I've caught up in the nanatsu no taizai manga. :kappa: What's your opinion on the manga?
I haven't read that manga, nor have I really read any manga other than the Angel Beats one. It's interesting and I'd highly recommend that one to anyone who liked the anime addoptation.
Technically it's not Manga, but I do recommend Tower of God. I've been waiting for the weekly chapter update, in which they are thankfully very consistent in, for over a few years now. Started reading it shortly after the first timeskip. It's a high action with HUGE world and very in-depth character building and crazy storyline. Even after all these years the main character just only managed to give another dude a small cut, and this dude had one of his hand tied behind his back and didn't even draw out all of his power. And oh, there's a lot more stronger people than this dude! So there is also still a lot of growth potential in this story. It's a Korean webtoon and since a few weeks they adapted it into a Japanese anime also, I saw the first few episodes and noted they left some things out, but if you don't wanna read 480+ chapters and just wanna watch, you can pick up on that instead.
