Masato Yoshino
At the beginning of 2007, he was briefly affiliated with the Wrestling Society X company that was run by MTV. He and Masato Yoshino were a tag team known as Team Dragon Gate, despite the fact the two were in rival stables at the time; Horiguchi was still aligned with face stable Do FIXER while Yoshino was in heel stable Blood Generation. They would only win an exploding cage timebomb deathmatch in their time in this promotion.
