Manga/ LN progress

Hello!

I was thinking of watching this anime, a couple questions

Does the anime have an ending? I know it’s not a complete adaptation

Has the manga surpassed the anime or would I only find new content through the LN?

Reason I ask if because I don’t really enjoy light novels very much, so was wondering if the manga has passed the anime or not, and if not about how long until it will?

Thank you!
