NiziU's Rio will be absent from the group's May 8 schedule due to health issues.

The announcement was made by JYP Entertainment through the group's official website earlier that day – just before Day 2 of 'KCON Premiere 2022' in Seoul, where the group was scheduled to perform.

"[...] Member Rio will not participate due to sudden illness during the rehearsal," the announcement read. "We sincerely apologize for the great concern and inconvenience caused to our fans."

The agency then continued that the decision was made in consideration of the artist's health and then asked for fans' understanding over the sudden news as the illness had occurred only just before the schedule.

Meanwhile, other artists scheduled to perform Day 2 of 'KCON Premiere 2022' include SHINee's Key, STAYC, The Boyz, and the cast of Mnet's 'Queendom 2.'
