Would a character's species affect the outcome of some of these? Because... Uhh... Koishi, being a youkai, is literally a kind of spirit or demon. Though that differs from a 'ghost' as Koishi was never mortal. As a satori, she IS made of the remains of corrupted mountain gods.

What would this do exactly? I'm sure Koishi isn't the only non human whose species may affect results but I can't really speak for anyone else.
