ウルティモ・ドラゴン
In 1991, he signed with the Mexican Consejo Mundial de Lucha Libre (CMLL) promotion. In CMLL, he adopted the Último Dragón mask and persona. "Último Dragón", which means "Last Dragon" in Spanish, was initially a gimmick that saw Asai claiming to be the last student taught by legendary martial artist Bruce Lee, whose nickname was "The Dragon". The gimmick was later dropped, but the name remained. Late in 1992, Misteriosito was turned into "Último Dragoncito", a Mini-Estrella version of Asai. During the same period, Asai also signed with the Japanese WAR promotion, and due to co-promoting, he was able to wrestle for NJPW. In Japan, he became IWGP Junior heavyweight champion twice, and in Mexico, he held various titles. In later years, he wrestled for AAA.
