A2O LITE: 9 Members, NEON and Lee Soo-man’s New Girl Group
A2O LITE is a nine-member girl group from A2O Entertainment, introduced with the debut digital single “NEON” on 13 October 2026. Lee Soo-man is credited as its producer, but the most useful place to begin is with the nine performers and their first release. This guide puts their names, song credits and debut dates together, then helps you choose between the official music video and three official performance uploads after reading.

Who are A2O LITE’s nine members?
The official A2O site, under Artists → A2O LITE, lists these nine names in this order:
YOUNG · OA · AYUNE · AIJING · HIMEKI · RADA · XILI · VORA · MERCI
For birthdays, dated ages, reported names and pre-debut experience, see our detailed A2O LITE member profiles, with a named portrait link for each member.
Nine names can feel like a lot on a first visit. Keep the official profile open beside the videos and pick two names to learn first; return for the others as you become familiar with the group. The profile’s labelled portraits are a useful reference, while the group’s official channel also carries member debut trailers.
LITE’s introduction uses the idea of different personal colours coming together to create a new light. It connects those colours with formative first experiences, then brings them together through music and performance. Read that as the group’s creative introduction: it gives “NEON” a starting idea without requiring you to learn a long fictional history before pressing play.
When did NEON come out?
There are three closely spaced dates in this debut. The showcase introduced the project in person, the official video appeared online, and the digital single followed. Here is the sequence in Korean Standard Time, UTC+9:
| Date in KST | What happened |
|---|---|
| 12 October 2026 | LITE and A2O SOUL appeared at the joint “WELCOME TO SOULITE” showcase at KINTEX in Goyang. |
| 12 October, 21:30 | A2O WORLD published the “NEON” official video linked below. |
| 13 October, 18:00 | “NEON” was released as LITE’s debut digital single. |
Sources: A2O’s showcase report, the original official video and its release announcement, and Melon’s NEON release page.
If a video search shows 12 October while a music service shows 13 October, both can therefore be correct. For a playlist, use the digital-single release date. For a particular performance, keep that broadcaster’s date with the upload.
Who made NEON, and where does Lee Soo-man fit?
The release’s published credits give Dem Jointz and YOO YOUNG JIN all three of the following roles: composition, lyrics and arrangement. They separately list “Produced By S.M. LEE.” That production credit is Lee Soo-man’s connection to the recording.
The same release page also lists Yoo Young-jin under “Directed by” and credits him with mixing, recording and background vocals. These are the audio release’s credits; the “Directed by” line should be read in that context. The useful picture is a production led by Lee alongside named collaborators responsible for the song’s writing and arrangement.
What should a new listener pay attention to? The label’s release notes point to a bass-led sound, contrasting vocal colours, a cappella and energetic performance. Those are useful listening prompts: follow the bass on one pass, then give the vocal changes your attention on another. You can make up your own mind about the track without needing a verdict from somebody else first.
NEON was No. 1 on which chart?
Melon’s TOP100 page labelled 21 October 2026, 06:00 KST placed “NEON,” credited to A2O and A2O LITE, at No. 1. That is the dated result checked for this guide. Source: Melon TOP100.
Melon is a South Korean music service, so keep its name and the timestamp attached when sharing the result. A chart position changes over time, and an individual service’s ranking answers a different question from a worldwide chart. The company name beside LITE on this listing is also worth noticing when searching for the recording.
If TOP100 and HOT100 look confusingly similar, our guide to Melon TOP100 and HOT100 explains how to keep the two chart names straight.
Which NEON video should you watch first?
Choose the official music video first if you want the release’s main visual introduction. After that, select the presentation that matches your curiosity. Four players are grouped at the end so you can finish the guide before watching.
- The official MV, from A2O WORLD: start here for the complete official video attached to the debut release, rather than a shortened repost.
- 15 October M COUNTDOWN, from Mnet K-POP: choose the dated television stage to see the group’s early music-show presentation.
- 20 October THE SHOW, from THE K-POP: try the newer broadcast appearance if you want another stage from the following week.
- 15 October full-group fancam, from M2: choose this to follow the ensemble and formation changes alongside the broadcast edit. “Fancam” here is the broadcaster’s own upload.
The M COUNTDOWN stage and M2 fancam come from the same 15 October appearance. They offer different viewing formats, rather than two additional concert dates. Their official titles preserve that connection: Mnet K-POP’s broadcast upload and M2’s full-group recording.
For the newer appearance, THE K-POP has both the 20 October performance and a separate “THE SHOW CHOICE” clip dated 20 October. Use the performance for the song and the separate clip for that programme segment.
How did Lee Soo-man get from SM to A2O?
The move happened in stages. SM’s 14 October 2022 disclosure records approval to end the production-licence agreement with Lee’s company, Like Planning, effective 31 December 2022. The share sale followed: SM’s 22 February 2023 filing records completion of Lee’s 14.8% transfer to HYBE. HYBE’s later annual report records acquiring another 868,948 shares on 7 March 2024. Contract and ownership changes therefore have separate dates.
A2O was already recruiting by early 2024. Its Japanese audition partner’s 24 January announcement described auditions across eight cities. The official A2O Rookies video on 25 October 2024 later introduced trainees with a S.M. LEE production credit. These are public milestones in the new project, rather than a precise legal incorporation date.
A2O expands its name to Alpha to Omega. Its About page presents “Zalpha Pop” and “Play2Create” as a vision involving a new generation of artists and participating creators. In its October 2026 announcement, the company calls Lee its key producer and visionary leader. LITE’s “NEON” places that producer role in the song credits.
A2O is the company; LITE, MAY and SOUL are separate acts. MAY’s artist introduction dates its formal debut to 20 December 2024, giving the company an earlier chapter before LITE. SOUL released “SUPERSTAR” on 13 October 2026 alongside “NEON”; its official profile identifies that song as a pre-release from its debut album. Keeping those names separate makes the label’s growing catalogue easier to explore.
For a newcomer, this history explains why Lee’s name attracts attention around the debut. The nine-member profile, the single and the group’s own appearances are where LITE’s introduction begins.
Where can you follow A2O LITE officially?
Use the A2O homepage → Artists → A2O LITE for the current profile, A2O WORLD for the linked “NEON” MV, and A2O LITE’s own YouTube channel for member introductions and group updates. The name uses the letter O, which helps distinguish it from unrelated “A20” search results.
You can start small: learn two names, play the complete MV, then pick one stage. Save the other versions for when you want a closer look at the group.
