9n9n!! is a new six-member Korean girl group managed by Japan-based Plus Production. The group consists of UNI, HAMU, SAKO, KIRIE, UMU and YUHA, with all six members publicly described by Plus Production as Korean. The agency says 9n9n!! will focus primarily on activities in Korea while also promoting in Japan.

As of September 21, 2026, 9n9n!! is still a pre-debut group. Plus Production has officially announced the group’s debut for September 22, 2026, at Ebisu Garden Room in Tokyo as part of the event “笑う門にはプリュきたる!!”.

That timing matters when reading a 9n9n!! profile. Unlike established K-pop groups with years of interviews, releases and television appearances, 9n9n!! has only recently been introduced to the public. As a result, detailed information such as the members’ birth years, legal names, heights, weights, blood types, MBTI types and official positions has not been publicly confirmed.

Rather than turning missing information into speculation, this profile focuses on what can currently be verified.

Plus Production’s official group page gives the Korean group classification, reading of the name, six-member lineup and September 22 debut date.

Who Is 9n9n!!

9n9n!! is Plus Production’s first Korean group, according to the company’s September 11, 2026 announcement. The agency specifically describes the members as all Korean and says the group will work mainly in Korea while also developing activities in Japan.

The group is written as 9n9n!!, while its Korean name is 큥큥 and its Japanese reading is きゅんきゅん. The group’s official social account uses the phrase” which can be understood in context as a playful concept around an intense or “heavy” feeling of affection. The same introduction uses the line that love is “the world’s most irresistible gravity.”

This concept gives 9n9n!! a distinctly cute and emotionally themed identity, but the group has not yet released enough music for a detailed discussion of its long-term musical style.

What Does 9n9n!! Mean?

The official material confirms that the group is read as 큥큥 / きゅんきゅん, but a detailed official explanation of the numerical spelling “9n9n!!” has not been published.

Kpop Profiles also lists the group’s name meaning as unavailable. Until Plus Production or 9n9n!! provides a fuller explanation, it is better not to assign a fictional meaning to the spelling.

When Will 9n9n!! Debut?

9n9n!! is scheduled to officially debut on September 22, 2026.

The debut event will take place at Ebisu Garden Room in Tokyo during Plus Production’s “笑う門にはプリュきたる!!” event. The event listing includes 9n9n!! among the performers, and Plus Production has separately described the date as the group’s debut.

Because today is September 21, the group should still be described as pre-debut in an article published on September 21. After the September 22 performance takes place, the current-status wording can be updated to “debuted.”

9n9n!! Formation and Pre-Debut History

The public history of 9n9n!! is short because the project was only formally introduced in September 2026.

Plus Production announced on September 11 that 9n9n!! would become the company’s first Korean group. The company also introduced the group as a six-member act designed to work mainly in Korea while maintaining an active presence in Japan.

The group’s official page lists six members: HAMU, SAKO, KIRIE, UMU, UNI and YUHA.

Public member introductions were then made through the group’s official social-media activity. Secondary profile documentation records UNI, HAMU, SAKO, KIRIE, UMU and YUHA as the founding lineup and records the order in which they were introduced publicly.

There is currently no publicly documented survival show, televised audition program or major Korean competition connected to the group’s formation.

There is also no evidence that 9n9n!! was formed through a large-scale televised survival series similar to Nizi Project, Produce 101 or Girls Planet 999.

Agency: Plus Production

9n9n!! is managed by Plus Production, officially 株式会社プリュ.

The company is headquartered in Shibuya, Tokyo and describes its business as entertainment production, artist discovery and training, management and promotion, music and video production, merchandise, events and publishing.

The company has managed and produced a range of Japanese idol acts and artists. Its official talent listings now include 9n9n!! alongside groups such as Honey Spice Re., JAPANARIZM, UPローチ, ROOKEY♡ROOKEYS, Melodys High and others.

The launch of 9n9n!! is therefore notable because the company itself calls the project its first Korean group.

What Is Different About 9n9n!!?

The unusual part of 9n9n!!’s structure is the combination of Korean members, Korean-focused activity and a Japanese entertainment company.

Plus Production says the group will be mainly active in Korea while also working in Japan. That gives the group a cross-market setup from the beginning rather than introducing it solely as a Japanese underground idol project.

Its September 22 debut event in Tokyo also reflects that dual-market strategy.

9n9n!! Members Profile

UNI Profile

Stage Name: UNI
Birthday: June 27
Birthplace: South Korea
Nationality: Korean
Representative Color: White
Japanese Level: ★★★★☆
Position: This information is not publicly available.
Birth Name: This information is not publicly available.
Birth Year: This information is not publicly available.
Height: This information is not publicly available.
Weight: This information is not publicly available.
Blood Type: This information is not publicly available.
MBTI: This information is not publicly available.
Chinese Zodiac: This information is not publicly available.

UNI is one of the six founding members of 9n9n!! and appears first in several early member-introduction records. Plus Production’s official profile gives her stage name as UNI, birthday as June 27, birthplace as Korea and Japanese-language level as four stars out of five.

One spelling point is worth highlighting for fans and search traffic: some secondary profile pages write her name as Yuni, while Plus Production’s own official talent page uses UNI. KpopBio should therefore use UNI as the primary spelling and can mention Yuni as an alternate search spelling where useful.

Her publicly assigned representative color is white, according to member-introduction material compiled by Kpop Profiles from the group’s social posts.

UNI’s Japanese ability is also one of the clearer pieces of information available before debut. Plus Production rates her Japanese level at ★★★★☆, suggesting that communication with Japanese audiences is expected to be part of her role in the group’s Japan activities.

There is currently little verified public information about UNI’s childhood, education, family, trainee history or previous entertainment activities. This information is not publicly available.

Likewise, there is no verified public information establishing a fixed position such as leader, main vocalist, main dancer or rapper. It would be misleading to assign one merely from teaser appearances.

UNI’s importance to the early 9n9n!! lineup is therefore best understood through the facts that are confirmed: she is a founding member, she is Korean, she has a June 27 birthday, she has a white representative color, and she has a relatively high publicly listed Japanese-language level.

As more interviews and stage content become available after debut, additional information about UNI’s performance style and personality may become clearer.

UNI: Publicly Confirmed Facts

UNI is a founding member of 9n9n!!.
Her birthday is June 27.
Her birthplace is Korea.
Her representative color is white.
Plus Production lists her Japanese level as ★★★★☆.

HAMU Profile

Stage Name: HAMU
Birthday: April 19
Birthplace: South Korea
Nationality: Korean
Representative Color: Pink
Japanese Level: ★★☆☆☆
Position: This information is not publicly available.
Birth Name: This information is not publicly available.
Birth Year: This information is not publicly available.
Height: This information is not publicly available.
Weight: This information is not publicly available.
Blood Type: This information is not publicly available.
MBTI: This information is not publicly available.
Chinese Zodiac: This information is not publicly available.

HAMU is one of the six founding members of 9n9n!!. Plus Production’s official talent page identifies her as a member of 9n9n!! and lists her birthday as April 19 and birthplace as Korea. Her publicly listed Japanese-language level is ★★☆☆☆.

Among the currently available member profiles, HAMU has one of the more modest Japanese-language ratings. That detail is particularly relevant because 9n9n!! is expected to operate between Korea and Japan. The group’s agency says Korea will be the main activity market, but Japan will also be an important part of its schedule.

HAMU’s representative color is listed as pink in secondary documentation based on the group’s member introduction posts.

The stage name HAMU appears consistently across Plus Production’s official talent directory and the group’s member listings.

There is currently no reliable public information about HAMU’s birth name, birth year, education, family background, training period, height, weight, blood type or MBTI. This information is not publicly available.

Her official profile also does not assign a specific vocal, dance, rap or leadership position.

That lack of fixed-position information should not be interpreted as evidence about her abilities. It simply reflects how early the group is in its public career.

HAMU’s profile is likely to expand quickly after the September 22 debut because live performances, interviews and fan content should provide more information about her role in the group.

For now, the strongest verified details are her April 19 birthday, Korean birthplace, membership in 9n9n!! and ★★☆☆☆ Japanese-language rating.

HAMU: Publicly Confirmed Facts

HAMU is a 9n9n!! member.
Her birthday is April 19.
She was born in Korea.
Her representative color is pink.
Her Japanese level is listed as ★★☆☆☆.

SAKO Profile

Stage Name: SAKO
Birthday: November 29
Birthplace: South Korea
Nationality: Korean
Representative Color: Red
Japanese Level: ★★★☆☆
Position: This information is not publicly available.
Birth Name: This information is not publicly available.
Birth Year: This information is not publicly available.
Height: This information is not publicly available.
Weight: This information is not publicly available.
Blood Type: This information is not publicly available.
MBTI: This information is not publicly available.
Chinese Zodiac: This information is not publicly available.

SAKO is a founding member of 9n9n!! with a birthday on November 29. Plus Production’s official profile identifies Korea as her birthplace and gives her a ★★★☆☆ Japanese-language level.

Her representative color is red, according to the group’s public member-introduction information.

SAKO has also provided fans with one of the clearest early glimpses into her excitement about 9n9n!!. In a message shared through her social media before the debut, she said that she was happy to meet fans again through 9n9n!! and acknowledged that her Japanese was still developing. She also said she intended to work hard on stage.

That message is useful because it gives context to her official Japanese-language rating without turning the rating into a broader judgment about her communication skills.

Another notable part of SAKO’s publicly documented background is her connection to earlier idol activity. Her social-media posts reference a previous project called YUMEKi and a final performance in June 2026. The same account also mentions appearing at an ARIS anniversary event.

Because these references come from SAKO’s own social activity rather than a detailed official biography, they should be treated as evidence of prior performance activity rather than as a complete career history.

Kpop Profiles also describes SAKO as a cosplayer.

Her birth name, birth year, education, training period, height, weight, blood type and MBTI have not been reliably published by Plus Production. This information is not publicly available.

SAKO’s exact group position is likewise unconfirmed.

What can already be said with confidence is that she enters 9n9n!! with previous live-performance experience, some Japanese-language ability and an existing connection with idol audiences. Her November 29 birthday and red member color are also publicly documented.

SAKO: Publicly Confirmed Facts

SAKO is a member of 9n9n!!.
Her birthday is November 29.
Her birthplace is Korea.
Her representative color is red.
Her Japanese level is ★★★☆☆.
Her social media documents previous activity connected with YUMEKi.
Kpop Profiles lists cosplay as one of her known activities.

KIRIE Profile

Stage Name: KIRIE
Birthday: August 20
Birthplace: South Korea
Nationality: Korean
Representative Color: Blue
Japanese Level: ★★★☆☆
Position: This information is not publicly available.
Birth Name: This information is not publicly available.
Birth Year: This information is not publicly available.
Height: This information is not publicly available.
Weight: This information is not publicly available.
Blood Type: This information is not publicly available.
MBTI: This information is not publicly available.
Chinese Zodiac: This information is not publicly available.

KIRIE is another founding member of 9n9n!!. Plus Production lists her birthday as August 20, birthplace as Korea, and Japanese-language level as ★★★☆☆.

Her publicly assigned representative color is blue.

Compared with some members, KIRIE has very little biographical information available outside her official profile. No reliable public source currently establishes her legal name, age, birth year, educational history, training period or fixed role within the group.

That makes KIRIE an example of why early pre-debut profiles need to be handled differently from profiles of established K-pop stars. A long biography can easily become misleading when the available source material contains only basic member data.

Her official listing nevertheless confirms the core details fans are likely to need when identifying her: she is Korean, she is part of the six-member 9n9n!! lineup, her birthday is August 20, and Plus Production currently gives her three stars for Japanese-language ability.

KIRIE has also been active through her own social-media account before the scheduled debut, interacting with other 9n9n!! members and participating in promotional activity surrounding the launch.

The blue representative color should not be confused with an official group color. Plus Production has not publicly announced one overall official color for 9n9n!!. The colors currently listed belong to individual members.

KIRIE’s profile will likely become more detailed after the group begins regular performances in Korea and Japan.

KIRIE: Publicly Confirmed Facts

KIRIE is a founding member of 9n9n!!.
Her birthday is August 20.
Her birthplace is Korea.
Her representative color is blue.
Her Japanese level is ★★★☆☆.

UMU Profile

Stage Name: UMU
Birthday: January 1
Birthplace: South Korea
Nationality: Korean
Representative Color: Orange
Japanese Level: ★★★★☆
Position: This information is not publicly available.
Birth Name: This information is not publicly available.
Birth Year: This information is not publicly available.
Height: This information is not publicly available.
Weight: This information is not publicly available.
Blood Type: This information is not publicly available.
MBTI: This information is not publicly available.
Chinese Zodiac: This information is not publicly available.

UMU has one of the most distinctive public profiles among the six members because she has already spoken openly about returning to the stage with a new group.

Plus Production lists her birthday as January 1, birthplace as Korea and Japanese-language level as ★★★★☆. Her representative color is orange.

In a message shared shortly before the group launch, UMU said that she had returned quickly and would now be meeting fans again with new members in a new group. That gives 9n9n!! a clear connection to her previous performance career.

Her social-media history also references an earlier group or project called S.T.A.N.D. and other pre-9n9n!! activities. Kpop Profiles lists her as a former member of S.T.A.N.D., but because a primary-source career archive was not located in the research available for this article, the detail should be treated as a secondary-source claim rather than an independently confirmed biography point.

UMU’s own profile gives her a particularly useful language advantage for the group’s Korea-Japan setup: her Japanese level is listed as four stars out of five.

Her social account also identifies her with an orange sea-angel/mendako-style character, and she frequently uses an octopus emoji. Because this originates from her personal account rather than an official group position announcement, it is better treated as a personal social-media motif than a formal representative emoji.

UMU has also directly spoken about both Japanese and Korean showcase activity, saying she hoped fans would watch the group’s Japan and Korea appearances.

Her legal name, age, birth year, formal training history, height, weight, blood type and MBTI are not publicly confirmed.

UMU: Publicly Confirmed Facts

UMU is a 9n9n!! member.
Her birthday is January 1.
Her birthplace is Korea.
Her representative color is orange.
Her Japanese level is ★★★★☆.
She has publicly described 9n9n!! as a new group in which she is returning with new members.

YUHA Profile

Stage Name: YUHA
Birthday: August 14
Birthplace: South Korea
Nationality: Korean
Representative Color: Green
Japanese Level: ★★★★★
Position: This information is not publicly available.
Birth Name: This information is not publicly available.
Birth Year: This information is not publicly available.
Height: This information is not publicly available.
Weight: This information is not publicly available.
Blood Type: This information is not publicly available.
MBTI: This information is not publicly available.
Chinese Zodiac: This information is not publicly available.

YUHA is the sixth member listed on Plus Production’s official 9n9n!! page. Her official profile gives her birthday as August 14, birthplace as Korea and Japanese-language level as ★★★★★, the highest listed rating among all six members.

Her representative color is green.

The five-star Japanese rating is especially interesting because Plus Production has announced that 9n9n!! intends to operate primarily in Korea while also promoting in Japan. For YUHA, that suggests a potentially useful communication skill when the group works with Japanese audiences, although the agency has not formally defined her role as a spokesperson or translator.

There is currently no reliable public information identifying her legal name, year of birth, education, family background, training length or official group position.

YUHA has, however, already appeared in the group’s online activity before debut, including schedule information surrounding the September 22 showcase. Public posts show that her individual account is associated directly with the 9n9n!! project.

The green member color is part of the individual member identity system that has emerged around the group’s launch. It should not be described as the group’s official color because Plus Production has not announced a group-wide official color.

YUHA therefore enters 9n9n!! with one of the strongest publicly documented Japanese-language profiles in the lineup. Beyond that, readers will need to wait for post-debut interviews and performance content before a more detailed description of her artistic role can be made responsibly.

YUHA: Publicly Confirmed Facts

YUHA is a founding member of 9n9n!!.
Her birthday is August 14.
Her birthplace is Korea.
Her representative color is green.
Her Japanese level is ★★★★★.

9n9n!! Member Information Compared

Member	Birthday	Birthplace	Representative Color	Japanese Level
UNI	June 27	Korea	White	★★★★☆
HAMU	April 19	Korea	Pink	★★☆☆☆
SAKO	November 29	Korea	Red	★★★☆☆
KIRIE	August 20	Korea	Blue	★★★☆☆
UMU	January 1	Korea	Orange	★★★★☆
YUHA	August 14	Korea	Green	★★★★★

The birthday, birthplace and Japanese-language ratings come from Plus Production’s individual member pages; the representative-color information is documented by Kpop Profiles from the group’s member-introduction material.

9n9n!! Positions

As of September 21, 2026, official fixed positions have not been publicly announced for the six members.

That means labels such as main vocalist, lead vocalist, main dancer, lead dancer, rapper, visual, center or leader should not be added to their profiles unless Plus Production or 9n9n!! formally confirms them.

This is particularly important for a new group. Early teaser appearances do not provide enough evidence to establish official positions.

9n9n!! Official Fandom Name

A dedicated official fandom name has not been publicly announced.

Therefore, the fandom name should currently be listed as:

Official Fandom Name: This information is not publicly available.

Fans may develop unofficial nicknames before the company announces one, but those should not be presented as official terminology.

9n9n!! Official Colors

Plus Production has not announced one official group color.

The members do have publicly listed individual colors:

UNI — White
HAMU — Pink
SAKO — Red
KIRIE — Blue
UMU — Orange
YUHA — Green

For SEO and editorial accuracy, KpopBio should describe these as member representative colors, not as the official group color.

9n9n!! Music and Discography

As of September 21, 2026, there is no confirmed official album, EP, digital single or music-video release for 9n9n!! in the sources reviewed for this profile.

The group’s first confirmed public milestone is its debut live performance on September 22, 2026.

This means the discography section should currently remain very small rather than being padded with unofficial audio, fan-made edits or incorrectly attributed releases.

Release Type	Status
Studio Album	None publicly announced
Mini Album / EP	None publicly announced
Digital Single	None publicly announced
Official Music Video	None publicly announced
Pre-Debut Song	None publicly announced
Debut Live	September 22, 2026

9n9n!! Music Style and Concept

It is too early to describe 9n9n!! as having a fully established musical identity.

The agency describes the group as a Korean group and the available secondary profile material characterizes 9n9n!! as a dance-and-vocal girl group.

The official introductory concept centers on emotional excitement, affection and “gravity,” using the repeated idea of a strong “kyun” feeling.

Once the group releases recorded music, it will become possible to discuss production style, vocal distribution, choreography, lyrics, concept progression and genre influences with much greater confidence.

9n9n!! Debut Live

The group’s first confirmed live appearance is scheduled for:

Date: September 22, 2026
Venue: Ebisu Garden Room, Tokyo
Event: 笑う門にはプリュきたる!!
Doors: 11:50
Start: 12:20

Ticket information published for the event lists both front-row and general admission options and confirms 9n9n!! among the performers.

This event is especially important because it marks the transition from pre-debut promotion to the group’s first official stage.

9n9n!! Activities in Korea

Although the debut showcase takes place in Japan, Plus Production says 9n9n!! will mainly operate in Korea.

The group has already indicated plans for both Japanese and Korean showcase activities. UMU publicly mentioned that fans should look forward to both the Japan and Korea “ohiro-me” or introduction stages.

A Korean event listing has also included 9n9n!! on the lineup for October 11, 2026, at Astra Live in Korea, showing an early indication of the group’s intended Korean activity following the Tokyo debut.

Because this event information is currently more clearly documented through event and member social sources than a dedicated Plus Production press release, it is best described as a scheduled/announced appearance rather than a completed career milestone.

9n9n!! Awards and Achievements

There are currently no major awards or music-show wins to report.

That is not surprising. The group has not yet reached its scheduled debut date.

For an accurate 2026 profile, the achievements section should therefore focus on documented milestones rather than creating an artificial award history.

Achievement	Status
Plus Production’s first Korean group	Confirmed
Six-member official lineup	Confirmed
September 22, 2026 debut announced	Confirmed
Korea-focused activity announced	Confirmed
Japan activity announced	Confirmed
Music-show win	None publicly documented
Major award	None publicly documented
Album chart achievement	None publicly documented

Plus Production itself identifies 9n9n!! as its first Korean group.

9n9n!! Tours and Concerts

No full concert tour has been officially announced as of September 21, 2026.

The most important confirmed performance is the September 22 debut live in Tokyo. Additional Korean activity is also beginning to appear in public event listings.

A future update should add tours and fan meetings only after Plus Production or the relevant event organizer officially announces them.

Brand Endorsements and Ambassadorships

No major brand endorsement or official ambassador appointment for 9n9n!! was identified in the sources reviewed for this article.

Individual promotional appearances should also not be described as brand endorsements unless the company or brand explicitly identifies them as such.

HAMU — @9n9n_HAMU
SAKO — @9n9n_SAKO
KIRIE — @9n9n_KIRIE
UMU — @9n9n_UMU
YUHA — @9n9n_YUHA

Note that the official agency spells the member’s stage name as UNI, even though some secondary sources use “Yuni.”

9n9n!! Net Worth and Revenue

There are no reliable public net-worth figures for 9n9n!! or its individual members.

Any websites claiming precise member net worth numbers at this stage should be treated cautiously unless they provide audited financial information or a credible documented source.

Future revenue for an idol group can potentially come from album and digital sales, streaming, concerts, merchandise, fan events, appearances and endorsements. However, there is currently no reliable public financial breakdown for 9n9n!!.

Therefore:

9n9n!! Net Worth: This information is not publicly available.

Individual Member Net Worth: This information is not publicly available.

Former Members

No former member has been officially announced by Plus Production as of September 21, 2026.

The current official lineup consists of:

UNI, HAMU, SAKO, KIRIE, UMU and YUHA.

UMU has publicly referred to previous idol activities, but those should not be confused with being a former member of 9n9n!!. She is part of the current founding six-member 9n9n!! lineup.

What Information About the Members Is Still Missing?

Because 9n9n!! is at the very beginning of its career, many profile websites may eventually publish additional data.

At present, however, the following information is not reliably public for most or all members:

Legal/birth names: Not publicly available
Height: Not publicly available
Weight: Not publicly available

MBTI: Not publicly available
Education: Not publicly available
Family background: Not publicly available

Keeping these fields open is better for long-term SEO trust than copying unverified numbers from fan accounts.

9n9n!! as a New Korean Idol Group in 2026

The most interesting aspect of 9n9n!! is not yet an award, chart ranking or streaming number. It is the group’s structure.

A Japanese entertainment company has created a Korean girl group made up entirely of Korean members and has announced plans to build the group’s main career in Korea while also bringing the act into the Japanese idol market.

That gives 9n9n!! a different starting point from many newer groups whose activities begin in only one market.

The group also already has a defined six-member color system and a romantic “kyun” concept. The next important stage will be translating that concept into actual music, choreography and live performances.

Until those elements are publicly available, it would be premature to describe the group as having a settled musical sound.

Conclusion

The 9n9n!! Members Profile 2026 is currently a pre-debut story rather than a conventional established-group biography. The six-member lineup of UNI, HAMU, SAKO, KIRIE, UMU and YUHA has been officially confirmed, all six members are Korean, and Plus Production has positioned 9n9n!! as its first Korean group.

The group is scheduled to make its debut on September 22, 2026, at Ebisu Garden Room in Tokyo, while the agency says its main activities will take place in Korea.

For now, the most useful facts are the members’ birthdays, birthplace information, representative colors and publicly listed Japanese-language levels. Much of the traditional profile data remains unavailable, and that is exactly where a trustworthy profile should stop rather than speculate.
