Taoism crew closest to seattle shrike crew.
They're in a constant war with the temple group because the temple group is like "people should join our polycule because we're nice and loving" and the taoist crew is like "people will join our polycule once they HEAR about our GENIUS IDEAS for LEFTIST LEADERSHIP". they'd both be a lot more effective if they could stop fighting.
there isn't really a "group" for double dealing charcter, just an actually very toxic shithead who started dating the cutest girl you've ever met and then ditched her to get fucked. said girl lived with reimu for a while after cause she had nowhere to go.
