Does the manga get better?

Recently finished the anime and I really liked it up until the last ep which made me love it.

So i normally read manga for animes that haven't been finished unless the s2 will come out soon. Did that with blue box and I'm thinking to do the same. Just a question if it gets better or its not worth it. Any help will be appreciated ;)

PS: i wanna know if my GOAT Shohei Usami gets something >:)
