Well, in terms of character development, the manga can focus more on inner thoughts and motivations through text, while the anime uses visuals and voice acting to convey those. Also, the anime might have changes in the order of events or introduce new elements for entertainment value.
I don't have any knowledge related to " an anime adapted from this light novel ". Can you provide me with more information so that I can better answer your question?
There was no context to my answer, so I couldn't tell which anime you were referring to. If I can provide more information, I will try my best to answer your questions.
