Are you saying next level from Light Novels ?? There isn’t one imo. In MOST cases of Japan / China LN’s are the start of a “thing” like it would be this novel starts then it gets adapted to a manga and then an anime. Or a anime or manga without the other but normally the LN is the source material from my experi.The reason why it is sometimes hard to go from LN to anime or manga is the LN “expresses” more from fights to locations to inner monologue and emotions. They can just use more descriptions for the things than manga which is stuck to drawing and anime which the budget is just insane and they can’t express it all honestly. There are some that do it well but not all.
What I have done personally is read manga or watched anime first. I then look to see if there is an LN and then I sit down and read it. More things will be explained and gaps will be filled. Sometimes it is good to start on LN and then watch an anime to see the artists ability to bring the work to “life” in a way.
