Magnum TOKYO would take over M2K, eventually transforming it into Do FIXER after Yasushi Kanda retired due to neck problems. Like all of his stablemates, he served as a backup dancer for Magnum TOKYO. During this time, Yokosuka formed a long lasting tag team with K-ness (formerly known as Darkness Dragon), and continued to establish himself as a choker. He and K-ness would make it to the finals of the inaugural Rey de Parejas Tournament in 2003, but lost to Dotti Shuji and Brother Yasshi. Also in 2003, he captured the UWA World Trios Championship for a third time that year in May with Genki Horiguchi and Ryo Saito.
