Does your character have blood?: Yep! Although he's a vampire so technically he sort of has two people's blood in him at various times??
Would their blood smell better or worse based on that Affinity: Aside from the vampire thing, definitely worse. Fai gets a little discouraged about his job (being a social worker is a particular kind of hell) but in general he's a very spunky, upbeat, happy person. When he's not being smacked with Retrospec surprises at least ;)
Any other notable facts about their blood: Vampire!! And also he still consumes a lot of sugar so there's that too :D
