Speaking of ARIA, a bit more information was revealed about the musical and live show to be held at Enghien-les-Bains. It was revealed that the event will feature numerous works that celebrate the births of IA and ONE, meaning that ONE will indeed be playing a role in the concert as well. Beyond that, 1st Place could not reveal any more information, but they did announce that they will soon be opening an official site for the event, and encouraged fans to stay tuned for updates on this completely unique concert experience.

New Album “IA/04” Announced

Afterwards, IA’s next compilation album, IA/04, was revealed, and is scheduled to go on sale on March 28th and retail for ¥3,500 JPY (about $32 USD). This 12-track album will not only feature many works from staple producers of IA’s greatest hits, but also many special collaboration cover tracks, as well as original songs from international song writers. Ever since IA/01 -BIRTH-, the aim of this album series has been to introduce the works of up-and-coming music producers to the fans through IA, with this particular release aiming to connect them with producers from all around the world. Judging by the track list that has been revealed so far, they are well on their way to accomplishing just that!

Unlike IA’s album series, this first installment of ONE’s album series aims to specifically support VOCALOID producers. ONE also remarked that while this is technically numbered as 01, she thinks it’s the equivalent of 04 in terms of quality level!

Other Information

Besides news, the livestream was filled with other fun corners and information reveals. Here are but a few that fans can enjoy.

Q&A Corner

IA and ONE answered questions asked by fans themselves! This session gave fans a rare opportunity to get to know a little more about the sisters’ respective personalities that they don’t typically see from them elsewhere.

Q: “In 18 Puzzle, it’s written that IA is 155 cm tall, and that ONE is 150 cm, but is that correct? If not, please tell me their real heights!” (IA/[email protected]廃人)
A: That is indeed correct. ONE’s a little displeased about being 5 cm shorter than her sister, but hopes to grow more.

Q: “What is your favorite food?” (Jade)
A: IA likes sakuramochi while ONE is fond of celery, as well as pistachios as an afternoon snack.

Q: “How long does it take for you to dry your hair?” (るーる)
A: It takes about 20 minutes for ONE to dry her hair, and it takes IA about 1 whole hour after factoring in treatment and using a hair dryer.

Q: “Do you both do your own hair?” (いちょう)
A: They normally do their own hair, but they sometimes get help from hair dressers, such as right before a live show.

Q: “Please show me your best game face!” (毛玉きっく)
A: That’s not really a question, but they obliged anyway.

Q: “Aren’t your normal outfits a bit cold to wear during the winter?” (san123)
A: Since they move around a lot during performances, they never get cold.

Q: “I bet you two never argue! I used to argue with my little sister a lot as a kid. Oh-ho-ho-hoo!!!” (平原雪@モナコインコンビ第2弾)
A: They actually do argue a lot, as there are a lot of things that ONE gets upset over. Remembering their last argument, ONE felt her anger re-surging, so they quickly moved on to the next question.

Q: “Happy birthday, IA and ONE! Would it be alright if I keep on loving you both forever?” (悔猫(IA廃))
A: Of course! Bring on the love!

Q: “What’s your favorite onomatopoeia?” (影の支配者)
A: IA likes “fuwa fuwa” (sound for fluffy things) while ONE is particular to “zara zara” (sound for rough things)

Q: “Do you ever get nervous before performing on stage? If so, then what do you do before you start performing?” (riyan herdian)
A: IA says that she never gets nervous before going onstage. ONE, on the other hand, gets nervous all the time, and plays a rhythm game on her phone to calm herself down.

Q: “Which of you is better at housework? Furthermore, please tell me what you like to cook!” (地鶏炭火焼)
A: ONE is better at cooking, and even has a vegetable garden. She doesn’t have a favorite recipe, but she does love fixing all sorts of salads, always making sure to include celery. Meanwhile, IA is better at cleaning and other housework.

Q: “If you two could travel, where would you like to go?” (吾妻)
A: When they’re not busy going overseas for work, IA would like to visit places like Hakone and Izu where she can take a dip in onsen.

Q: “I’d like to see you both look when playing a horror game, or watching a horror movie.” (白猫翼)
A: ONE may like playing games, but she gets startled and screams easily, so she stays away from horror games.

Q: “Where do you two get your cuteness from?” (馬(軍用馬))
A: After hesitating for a while, IA answers “I guess from the staff and their hard work.” Perhaps the best answer that she could give.

Q: “When will there be the next song duet from you?” (camila catalano)
A: Today!

Q: “When do you normally go to sleep, and when do you normally wake up?” (ぜろ!祝1万ツイート達成)
A: IA is the early-to-bed-early-to-rise type, whereas ONE is always staying up late and sleeping until noon the next day.

Q: “I want to see you two put on a manzai act.” (とある鉄オタのサブ垢)
A: While not too pleased with the staff for selecting this question, IA and ONE still tried their hand at a manzai performance to give their fans a rare treat, complete with some slapstick involved. But IA ended up getting hurt from that, so they decided to stop after that.

out of service

Both Hayao Konishi and Kai Ohno from out of service appeared in the flesh as special guests of the livestream event to talk about the work that they have done with IA throughout the years. From contributing to her albums to even writing songs for video game collaborations with IA, they’ve come to see her as something of a co-worker at 1st Place, their senpai to be exact.

In 2017, the pair appeared at both Niconico Cho Kaigi and Niconico Cho Party to perform with IA in some manner, and even helped promote the VOCALOID Keyboard for multiple occasions. They even took the opportunity to do so again during the livestream, marking one of the first times that fans have been able to listen to IA’s voice on the keyboard online.

As for their goals going into 2018, Konishi hopes to complete their next album and continue performing at live concerts, including the upcoming PARTY A GO-GO FINAL concert, and hinting at an appearance at ARIA as well. By contrast, Ohno stated a more individualized goal: improving his skills at and making videos for Super Mario Maker! He is also concentrated on his next performance with IA on Anisong★Station this upcoming Monday.

The pair concluded their guest appearance with a video digest on one of their performances from last July in which they performed ビットチューン (Bit-tune) with IA and ONE, which also serves as one of the featured songs in the above-mentioned collaboration with Groove Coaster 3EX Dream Party.


After out of service, IA’s own voice provider, Lia, appeared via video message from Hong Kong to wish IA and ONE a happy birthday. After singing them the Happy Birthday song and apologizing profusely for not being able to be there in person, Lia then took the opportunity to promote her new album called “Revives,” a compilation of her covers for famous anime songs. One look at the tracklisk below may reveal some recognizable tracks for anime fans.

One such supposed anime fan, ONE, even remarked afterwards on how the album was filled with her favorites, and intends to buy it as soon as it is released. IA admits that she is not as much of an anime fan as ONE, but is still excited for the opportunity to listen to Lia sing.



The roughly two-hour livestream contained some really big album, merchandise, and collaboration reveals. The latter especially strongly suggests 1st Place’s more aggressive aim to expand into the international market, and spread the appeal of IA and ONE worldwide by working together with overseas companies and music producers. The concert information was comparatively scarce, but no less indicative of the company’s commitment to internationalizing their voice synths in 2018. The hints that were given about ARIA – from the show’s focus on IA and ONE’s births to the reveal of the てるみい (Tell Me) music video – could mark a whole new direction for the ARIA sisters and their future promotions.

The livestream also reminded fans just how involved the staff behind the creation of IA and ONE are with their activities. Whether it’s out of service or Lia, or じん (Jin), the individuals responsible for making IA and ONE who they are have never stopped supporting them, and it shows in their worldwide success. All other VOCALOID companies can truly learn from the example and the standard that 1st Place has set for the promotion of a virtual artist.

VNN has profound respect for the work done by our new partner, 1st Place, and will continue to be the place for all of your IA and ONE news.
