LOONA is/was a kpop girl group under Blockberry Creative. They've de facto disbanded after a series of lawsuits.

Five of the members debuted in Loossemble (under CDTENM).

Five of the members debuted in ARTMS (under MODHAUS).

Chuu debuted as a soloist (under ATRP).

The question will resolve in favor of the first act that achieves a win on one of the following Korean music programs: The Show, Show Champion, M Countdown, Music Bank, Show! Music Core, Inkigayo.

Loossemble and ARTMS are both scheduled for a comeback in the upcoming months and a Chuu comeback is also rumored to happen soon. However, there is absolutely no guarantee any of these acts will get a win with their upcoming comebacks, or ever. I will resolve an option N/A if the act in question disbands, or permanently ceases their activities.

I will add any future ex-LOONA acts as an option as soon as a debut/comeback is scheduled (e.g. Yves' debut, Heejin or OEC comeback). I will not add LOONA if they get back together, since LOONA has already achieved multiple music show wins.
