Do you ever wonder how Nasu would write some of the characters from Apo/FSF/Case Files/other spinoffs not written by him? You can interpret this question as either "what if Nasu included them in a future work for whatever reason" or "how would this look if Nasu had written it in the first place," whichever you find most interesting. If the question is too broad, just pick your favourites.
Not really, because most spin-off characters are built up from the foundations of characters Nasu wrote, so I feel like I've already read Nasu's versions of them.
