ミラノコレクションA.T.
Ibushi made his debut in Dragondoor on its debut show on July 19, 2005, taking part in Taiji Ishimori's babyface team along with Milanito Collection a.t. and Little Dragon. They were pitted in a handicap match against Aagan Iisou (Shuji Kondo, Takuya Sugawara and Yasshi), but they were defeated. Ibushi then teamed up with Ishimori to take part in the Aquamarine Cup tag tournament, beating at the first round a team of Aagan Iisou (Toru Owashi and Shogo Takagi) but being eliminated at the second by another (Kondo and Yasshi). After wrestling in the short-lived promotion for some months, Ibushi did a special apparition in its last show, figuring as a new member of Italian Connection (Milano Collection A.T. and Berlinetta Boxer) under the name of "Ibushino", in parody to Yossino, to defeat Aagan Iisou.
