Saito would go on to form his own stable, Dark Agents, with Takashi Sugiura, Masao Inoue and former Heisei Ishingun stablemate Shiro Koshinaka. He awarded himself the GHC Great Happy Christmas Championship in 2004, a title that was defended only once a year, on Christmas Eve. He would also challenge for the GHC Heavyweight Title on two separate occasions, in 2004 against Kenta Kobashi and in 2005 against Takeshi Rikio.
