【自己紹介】彗星の如くあらわれたアイドルVTuber!!!【 01】

Suisei's introduction.


"It's your shooting star, your diamond in the rough, idol VTuber Hoshimachi Suisei!"

A forever 18 VTuber who deeply loves singing and idols.

Her dream is to one day hold a live concert in Tokyo Budokan.[13]


Suisei is a modest, multi-talented singer and aspiring idol who is among the more level-headed members of hololive, though she also has a childish streak. After her unexpectedly compelling performance as a traitor in a game of Project Winter, she gained a reputation for remorseless sociopathy behind a facade of polite sweetness.[14] No one seems to know how much of the "Psychopath Suisei" persona is real or not, but Suisei herself acknowledges that it is extremely funny and has referred to the incident on multiple occasions.


She has light blue hair in a side ponytail and blue eyes. She wears a dark striped blue hair ribbon with a black plaid cap with a crown attached to it. She wears a grey plaid dress uniform with part of the skirt being dark blue and ruffly. She has black shoes and asymmetrical socks.

  • Her fanbase is officially called "Stargazers," while in Japanese they are called "Hoshiyomi" 「星詠み」.


  • Notable units and groups Suisei is part of:
    • "Shiranui Kensetsu"「不知火建設」"Shiraken" for short and "Shiranui Constructions" in English, alongside Shiranui Flare (president), Omaru Polka (vicepresident), Sakura Miko (education director), and Shirogane Noel (intern). Suisei is the PR/sales director. This unit is named after their Minecraft company founded by Flare. Shiraken has its own Twitter account opened on 7 September 2022, this seems to mark Shiraken as an official unit within hololive as their Twitter account promoted a collaboration with Kyoto International Anime Fair shortly after release on 12 September 2022. By the time of "hololive Summer 2023" Shiraken was one of the featured units in the event's website, and even received an original song on 27 August 2023 called "NAKAMAKA."[82][83][84]
    • "Hoshimatic Project," alongside Tokino Sora, Natsuiro Matsuri, Aki Rosenthal, Oozora Subaru, Tokoyami Towa, Momosuzu Nene, Hakui Koyori, Sakamata Chloe and Kazama Iroha. The project was conceived by Suisei as she wished to make activities proper of a big idol group including activities such as pratice routines. The unit was revealed on 6 November 2023 and their first practice stream was on 13 November.[85][86]
    • "miComet," alongside Sakura Miko.
    • "Startend," alongside Tokoyami Towa and Minato Aqua.
    • "Star Flower," alongside Moona Hoshinova, AZKi, and IRyS.
    • "Doukyo's"「同居ーず」, alongside Kiryu Coco and Amane Kanata.
    • "Hoshi no Kanata"「星の彼方」, alongside Amane Kanata.
    • "Karashi-gumi" 「からし組」 or "karASHi" (as Hoshimachi), alongside Akai Haato (Akai) and Shiranui Flare (Shiranui).
    • "HoshiStar," alongside Moona Hoshinova (Moon), Yozora Mel (Night Sky), and Tsukumo Sana (Space), created by Suisei herself with taking inspiration from UMISEA.
    • "Hoshi Clan," alongside Moona Hoshinova.
    • "MOMAS," alongside Sakura Miko, Nekomata Okayu, Houshou Marine, and Hiodoshi Ao



  • Suisei's surname Hoshimachi「星街」can be divided as such.
    • The first kanji「星」can be read as "Hoshi/Sei" that means "star."
    • The second kanji「街」can be read as "Machi/Kai/Gai" which means "city."
    • Hence, her surname can be translated as "City of stars."
    • Suisei occasionally romanizes her last name as "Hosimati," rather than Hoshimachi, which can be seen in her Twitter handle and various online usernames.


  • Considerably multi-talented as she is capable of drawing (her original image was drawn by herself), edit videos, sing, cook and is also a skilled gamer.
  • Suisei lives with her older sister, who is referred to by fans as "Anemachi." Anemachi is extremely attached to Suisei and used to be dependent on her for her cooking skills, but now has turned around and is often cooking for Suisei; Anemachi is very popular between Suisei's friends, specially Miko.
  • She is notably good at playing competitive Tetris.
  • The hashtag #星街すいせい3D (#HoshimachiSuisei3D) became a trending topic worldwide on Twitter when she debuted her 3D model on YouTube.
  • Her birthday and her debut date are the same.
  • A few years before considering being a VTuber, Suisei participated in several auditions for real-life idol agencies, but was rejected due to the "Jack of all trades, Master of none" trait, according to her. This led to her becoming a Virtual Idol, as a way of not giving up on her dream. However, she was already tired of trying by the beginning of 2019 as an indie Virtual Idol (since she worked in an izakaya [Japanese pub], and also had to do the editing of her own videos and other VTubers). Suisei almost gave up but decided to make one last try. She went to COVER Corp to audition for hololive, but was also rejected, apparently for the same reason as the real-life agencies, since COVER Corp considered that she had many skills (speaking, singing, dancing, drawing and gaming) that could let to failing trying to do everything due to an overload of work. She claims that after receiving rejection e-mail, she e-mailed back seeking for a second chance and is open for suggestion. As a result, hololive replied back to have a second talk; then they told her that she could join, but on the condition of joining INoNaKa Music and focus on music. After more difficulty in INoNaKa Music mostly due to company policy that nearly broke Suisei's heart, she was finally transferred to hololive officially.[87][88][89]
  • Suisei has won two editions of hololive Mario Kart 8 Deluxe Tournament.
    • She won the second edition of the tournament on 11 January 2021.[90]
    • She also won the fourth edition of the tournament on 7 January 2023.[91]
  • Suisei popularized the phrase "Hi, honey!" during a Duolingo English learning stream.[92] Although Akai Haato was technically the first to use it, Suisei's endearing delivery of the line, coupled with her recent voice change, has since caused many other members of hololive to repeat it in a similar fashion.[93]
  • Suisei featured "7days," the theme song for episodes 1-3 of the VR game "DYSCHRONIA: Chronos Alternate."[94][95]
