Riko (Miyu Tomita) and Regu (Mariya Ise) are a Japanese doujin circle built around voice actresses Miyu Tomita and Mariya Ise. The project sits between independent music and anime voice-actor culture, using a collaborative artist identity rather than a large public-facing band profile. Its releases are credited to Tomita and Ise together, which makes the name useful for anime-music cataloging, voice-actor discographies, and character-song adjacent searches.
Miyu Tomita, born November 15, 1999, in Saitama Prefecture, Japan, is also active as a singer under Nippon Columbia. That solo-career context helps explain why listeners encounter Riko and Regu in anime-related credits even when the circle’s public history and discography remain compact. For fans of both performers, the entry functions as a clean way to group collaborative releases and preserve the connection between the two voices.
