OOhh!
Kingston has very autumnal... vibes... He associates autumn with the Obon festival (celebrated to remember deceased ancestors) bc it's a big thing in his family tradition being very closely associated with ghost pokemon and all that hehe. So the season would be like a more sobering reminder that our time is very limited but its also a very introspective feeling qwq

Ruth (no idea)

Mirajane probably spring bc I associate her with... just bringing happiness to other people :')
