Kodaka, Shuhei Yamaguchi (the executive in Akatsuki that greenlit Tribe Nine I think), and Katsunori Suginaka made a doujin circle Neo Neon Tribe to continue Tribe Nine's story. It says they are sanctioned by Akatsuki so there shouldn't be any problems legally for them to do this even if they don't own the IP. I'm not sure what exactly is Katsunori Suginka's involvement in Tribe Nine though. I don't remember his name coming up before
