Ariaz

One of the best, most underrated rookie groups there is. They debuted on the 24th of October 2019 with their debut EP Grand Opera, with one of the most aesthetic MVs ever, Moonlight Aria (a bop). They are under Star Empire's subsidiary label Rising Star Entertainment.

Ariaz has 6 members,

Yunji (Kim Yunji) - Leader, Main Vocalist, Lead Dancer
Dawon (Lee Dawon) - Main Vocalist
Sihyeon (Kang Sihyeon) - Lead Vocalist, Visual
Yeori (Choi Yeori) - Main Rapper, Main Dancer, Vocalist
Hyogyeong (Jang Hyogyeong) Lead Vocalist, Lead Rapper
Jueun (Jo Jeuen) - Vocalist, Maknae

Many people who support Ariaz call them Loona 's secret sister group as they have a similar style to Butterfly.

They're amazing rookies who I've followed and supported since debut so please check them out as they are still quite small in fanbase!!!
