Takuya Sugawara
Along with most of his Toryumon class, Sugi joined the Dragondoor promotion in July 2005. He was introduced in a vignette by top babyface Taiji Ishimori, who described him as a close ally carrying the genes of Último Dragón. As such, Sugi appeared as , a character wearing a mask and suit patterned after Dragón, very much like the wrestler Dragon Kid from rival promotion Dragon Gate. In his first match, Little Dragon teamed up with Ishimori and the rest of his allies, Kota Ibushi and Milanito Collection a.t., in a losing effort against the popular stable Aagan Iisou (Shuji Kondo, Yasshi and Takuya Sugawara). His next and last high level match in the short-lived promotion would be at the final event, fighting with Ishimori against Stoned (Kei Sato and Shu Sato), being defeated after an intervention by Kagetora and Maguro Ooma. Dragondoor folded down shortly after.
