Kingston's initial team: Mercedes, Cooper, Vespa (and i forgot the rest) were named after car brands... and his current ghost team were named after ghibli characters: Calcifer, Sophie, Kohaku, Moro, Eboshi

Ruth's team: Mila, Aquilla, Faelan, Lyall (just naming them what sounds nice)

Mira's team: I have no idea YET, I might name them after classic book characters QWQ
