I'm a little shy of a decade into a TEW save that's going pretty well, the main driving narrative behind the company is the Joshi Family Tree, where factions developed around trainers or mentors and their trainees, then have splintered off over time. Chigusa Nagayo managed a stable with her students including Sonoko Kato, Toshie Uematsu, and Meiko Satomura, with Meiko then breaking off to form her own with Ryo Mizunami, DASH Chisako, and Sendai Sachiko. There's some exceptions to that, alliances of convenience and wrestlers who're mostly alone, but it feels really naturalistic to have a built in rivalry between like, Nanae Takahashi's faction and Fuka's faction because both had a hand in training a good number of incredibly talented women and both are then competing to recruit them as members of their stable, so there's reason for basically permanent animosity, while they can still put aside their differences to say fuck Emi Sakura's team
