Fukamasa retired almost immediately after T2P closed, and Sugawara spent most of his time back in Mexico while Mori wrestled in Toryumon.

This team would continue for some time, but all the members of Aagan Iisou were fired from Dragon Gate on December 31, 2004, for controversial and mostly unexplained reasons.

In this promotion, Aagan Iisou was put in a feud against Taiji Ishimori and his home army, but Dragondoor's short lived existence impeded any development.

Around this time, Sugawara's allegiance to Aagan Iisou was tenuous, and Gamma capitalized on it to persuade him to join his Stoned stable, which acted mainly in Michinoku Pro Wrestling.

The UWA World Trios Championship was then vacated, and Sugawara allied with Toru Owashi's faction "Animal Planets", although did not officially join them.

Sugawara won the vacant UWA World Trios Championship for the second time with Toru Owashi and Nobutaka Araya by defeating the Hell Demons Braman Shu, Brahman Kei, and Go.

Sugawara and Fujita hold the record for the longest NWA Intercontinental Tag Team Championship title reign of 399 days.

He teased reuniting with Anthony W. Mori and reforming the Royal Brothers, but instead joined up with top heel stable Real Hazard.
