Or persona fans

I would have gone with Touhou

Notably, Fates actually cut out a step entirely by doing this to Hisame in the localization itself.
(Their argument is that in the original script he had basically no personality. 1: No I don't want "punched up" scripts I want authentic authorial intent. 2: Was this actually an improvement? Was it really?)

Touhou has an excuse in that most of the characterization amounts to a handful of dialogue lines said before a boss battle and that’s it. Fans fill in the blanks.

And some become canon because mainline books run with it

Eh, that doesn't really apply anymore. At least for most of the cast. There's enough expanded universe material out there that we have a pretty good idea of what most of the major players are like.
