>>29161513nta, but let me repost a list of Mori's connection with some amount of crossover with Holos:
Kokorobeats is followed by A-Chan, Marine, Aki, Fubuki, Mel and 'Noel'
for FT you already mentioned RBC and Mel, but there's also Koro-san and Fubuki (who posted pics from FT events) + now Okayu is getting two song tracks made by them
there's also ill.bell who posted how proud he is of working with Mori in the past - who in turn is followed by Suzy, RBC and has ties with 'Kanata'
rapbit, who had 'Mori' as a special guest in his events and attended her sololive is followed by Polka
and there are obviously the PPP animators who work with FT who are followed/in contact with all of the above and people like Choco, Ayame or Sora
