There are a lot of relatively small but interesting details that are noted about characters throughout the story, but aren't often shown in their bios. For example, last names. Forgot for the longest time that Luna has a last name. Does Yufine have a last name? What about Alencia? While some names are simpler to recall (Angelica Angelus), many are not, especially if they have been out of the story for a while (Silkyria Eyu La Safaye). It would be nice to have it reflect in the in-game bio rather than relying on memory or a wiki search. Also, if they have a birthday (does Orbis' calendar match ours?), adding that too would be nice. Probably not something a lot of folks care about, but would be nice to see added to their character bios.
