Joe Doering
In the fall of the year, Muto and his partner Joe Doering participated in the 2007 Real World Tag League, which they won by defeating Satoshi Kojima and Suwama in the final on December 9. This earned them a title shot for the World Tag Team Championship against Kojima and TARU on January 3, 2008, which Muto and Doering won. In April, Muto entered the 2008 Champion Carnival, winning only two matches and failing to advance in the round robin stage. Muto and Doering lost the World Tag Team Championship to Minoru Suzuki and Taiyo Kea after a five-month reign on June 28.
