ONEUS

ONEUS (원어스) is a five-member boy group currently under B.WAVE Entertainment. Formed by RBW as a six-member group, they debuted on January 9, 2019, with their first mini album, Light Us. The group's name carries the meaning of "one us," symbolizing unity between the members and their fans, and is also interpreted as "one world" in Korean.

RBW introduced ONEUS in 2018 alongside their brother group ONEWE. Prior to debut, the two groups released the collaboration single "Last Song." ONEUS officially debuted in January 2019 with Light Us and later released the mini albums Raise Us and Fly With Us. They made their Japanese debut in August 2019 with the single "Twilight" and subsequently released the Japanese single "808." During this period, member Ravn temporarily halted activities due to health concerns before later rejoining the group.

In 2020, ONEUS released the single album In Its Time and participated in Mnet's competition program Road to Kingdom, where they ultimately ranked fifth. They later released the mini album Lived and the digital single "Bbusyeo."

In 2021, the group released their first studio album Devil, followed by the mini album Binary Code and additional Japanese releases. They launched the ONEUS Theatre project and released the mini album Blood Moon in November, earning their first music show win with "Luna." They also collaborated with ONEWE on the single "Stay." Toward the end of the year, Ravn temporarily suspended activities.
