About OWIS
OWIS is a 5 member virtual girl group. Their name is an acronym for Only When I Sleep. The group is on a different time and space, meaning that live in the 2600's, compared to the current year. Each of the members reside in a city called Archel. They formed a group together when they woke up one day in Archel with no memories. Although nothing has been confirmed by the company, it's rumored that Lee Hae-in (soloist/creative director), ADORA (soloist/producer), Luri (contestant on Produce 101), Ryu Sujeong (Lovelyz), and Jini (former NMIXX/soloist) are the voices behind the members.
