オープン・ザ・ドリームゲート王座
2005 brought about a major resurgence in his career. He opened the first show of the year on January 9 by pinning CIMA in a six-man tag match. Then, when he appealed for a shot at the Open the Dream Gate title, held by Masaaki Mochizuki, he was given a January 14 singles match with Milano Collection A.T. as a hurdle, and he defeated Milano after four years of losses to him. He failed to win the Open the Dream Gate title in the February 6 match. He spent the remainder of the year garnering high-profile victories, as well as two Open the Triangle Gate Championship reigns with Genki Horiguchi and Dragon Kid, and when Magnum began to move down a different path with his Renaissance project, he named Saito the new leader of Do Fixer. Saito then won a feud with CIMA, and in December he won the inaugural King of Gate Tournament. His momentum continued right into February 2006, when he beat Magnitude Kishiwada to win the Open the Dream Gate Championship and became the ace of the promotion.
