After losing a match to Takeshi Minamino, the two allied themselves with Takayasu Fukuda and formed Los Salseros Japoneses, a salsa band stable.

Los Salseros Japoneses and Sailor Boys traded victories, but the former managed to capture the promotion's main title, the UWA World Welterweight Championship, in a three-way match among the members of the team themselves, which was won by Minamino.

Los Salseros Japoneses continued their run at Michinoku Pro Wrestling, with Hanai and Fukuda winning the Futaritabi Tag Team League 2004 upon their debut.

Sakai also joined El Dorado Wrestling, where he started teaming up with Shuji Kondo's Aagan Iisou stable in an attempt to become a member.

At the end, Ken would lose a match to Sugawara which stipulated that he could not even occasionally team up with them, so he abandoned his aspirations and became freelance, not allied with any stable.
