I think I'm tied between Reunion/Neo-Reunion and the Abyssal Hunters or Babel. For Reunion it's because of Talu- nah I like their aesthetics the most and the fact that they were a peaceful group before Koschei/Kaschey possessed Talulah. For the Abyssal Hunters it's the fact they're just ripped from Bloodborne. And for Babel it's W and the Special Ops Group.
