In 2010, Senga debuted in Pro Wrestling Noah as Ronin, a creepy samurai ghost, and attacked Sugi after a match against Taiji Ishimori. The two had a heated feud both in Noah and AAA and toured Mexico. Ronin became an ally of Dark Family (Dark Cuervo and Dark Ozz) and had matches in All Japan Pro Wrestling, being defeated at the end by the returning Sugi.
