## Character design and persona
**Pirate lore.** Her official profile describes a character who loves jewels, treasure, and money, whose dream is to become a pirate and go treasure hunting, and who is "stacking up money as a VTuber on the great lands" in order to get a pirate ship.[1](https://hololive.hololivepro.com/en/talents/houshou-marine/) The same profile states her long-form wish: to set sail with her viewers and, at the journey's end, say "My greatest treasure was this scenery and the friends we made along the way."[1](https://hololive.hololivepro.com/en/talents/houshou-marine/)
**The persona.** Hololive's profile describes her as "a sensual, femme fatale boss, and a young one, at that! (Around 17)", a running gag about her age, and states that "her pirate outfit is just cosplay".[1](https://hololive.hololivepro.com/en/talents/houshou-marine/) The boundary between character and performer is therefore part of the official material itself: the pirate identity is a role.[1](https://hololive.hololivepro.com/en/talents/houshou-marine/)
**Design and fan ritual.** Her visual design is by the illustrator Akasa Ai.[1](https://hololive.hololivepro.com/en/talents/houshou-marine/) She opens streams with the pirate greeting "Ahoy" (アホォイ) and closes them by calling 出航～ ("setting sail"), to which viewers reply ヨーソロー; her fan community is the 宝鐘の一味 ("Houshou's crew"), whose mark is the pirate flag 🏴☠️.[5](https://dic.nicovideo.jp/a/%E5%AE%9D%E9%90%98%E3%83%9E%E3%83%AA%E3%83%B3) She addresses her overseas viewers as "Overseas Sexy Guys & Ladies".[1](https://hololive.hololivepro.com/en/talents/houshou-marine/)
**Her own art.** Marine is herself a skilled illustrator: she has drawn her own self-portrait and other hololive members, and hand-drew part of the promotional video art for her original song 美少女無罪♡パイレーツ.[5](https://dic.nicovideo.jp/a/%E5%AE%9D%E9%90%98%E3%83%9E%E3%83%AA%E3%83%B3)
## Career and debut
Marine debuted on August 11, 2019 with a 58-minute first stream on the channel Marine Ch. 宝鐘マリン, introducing herself in the video description as "ホロライブ3期生、宝鐘海賊団船長。宝鐘マリン（Houshou Marine)です" (hololive 3rd [Generation](https://www.edgepedia.org/generation), captain of the Houshou Pirates); the debut video has since drawn about 1.4 million views.[2](https://www.youtube.com/watch?v=xmcncA-dWFc) She began posting on Twitter on August 1, 2019, together with cohort members Shiranui Flare and [Shirogane Noel](https://www.edgepedia.org/shirogane-noel).[5](https://dic.nicovideo.jp/a/%E5%AE%9D%E9%90%98%E3%83%9E%E3%83%AA%E3%83%B3)
Her generation, hololive 3rd Generation, marketed as ホロライブファンタジー (hololive Fantasy), consists of [Usada Pekora](https://www.edgepedia.org/usada-pekora) (兎田ぺこら), Uruha Rushia (潤羽るしあ), Shiranui Flare (不知火フレア), Shirogane Noel (白銀ノエル), and Marine.[5](https://dic.nicovideo.jp/a/%E5%AE%9D%E9%90%98%E3%83%9E%E3%83%AA%E3%83%B3) • [7](https://myanimelist.net/people/66647/Marine_Houshou) A 3D model was implemented for her on February 15, 2020.[5](https://dic.nicovideo.jp/a/%E5%AE%9D%E9%90%98%E3%83%9E%E3%83%AA%E3%83%B3)
## Content and streaming style
Her output is organized around the pirate-captain character: the Ahoy opening, the 出航～/ヨーソロー closing call-and-response, and the 宝鐘の一味 fan identity frame talk streams in character.[1](https://hololive.hololivepro.com/en/talents/houshou-marine/) • [5](https://dic.nicovideo.jp/a/%E5%AE%9D%E9%90%98%E3%83%9E%E3%83%AA%E3%83%B3)
**Collaborations.** Her collaboration record extends beyond hololive. Through a February 16, 2020 stream of the TAITO game Touhou Spell Bubble she was noticed by beatMARIO and collaborated with the doujin circle COOL&CREATE on the album 『#幻想郷ホロイズム』; on April 12, 2020 she appeared remotely with ZUN at 超東方ステーション＠ニコニコネット超会議2020.[5](https://dic.nicovideo.jp/a/%E5%AE%9D%E9%90%98%E3%83%9E%E3%83%AA%E3%83%B3)
## Music career
**Original songs.** Her credited songs include *Ahoy!! Warera Houshou Kaizokudan☆* (2020), *I'm Your Treasure Box ＊あなたは マリンせんちょうを たからばこからみつけた。* (2022), and *Bishoujo Muzai ❤ Pirates* (2023).[7](https://myanimelist.net/people/66647/Marine_Houshou) The last of these, 美少女無罪♡パイレーツ, went viral on TikTok and became the release that spread her name most widely, according to her official album site.[4](https://ahoy-youre-all-pirates.hololivepro.com/)
**First album and solo live.** Her first full album collects her previous singles and new material across 14 tracks, running from the TikTok-viral 美少女無罪♡パイレーツ to the Giga-produced *I I I*.[4](https://ahoy-youre-all-pirates.hololivepro.com/) The album was announced with the lead track 幽霊船戦, released ahead of the album with a full-animation music video.[6](https://www.oricon.co.jp/prof/772605/) Her first solo live, 宝鐘マリン1stライブ「Ahoy!! キミたちみんなパイレーツ♡」, was covered in an official report published December 6, 2024, and a Blu-ray of the show opened pre-orders on December 11, 2024.[4](https://ahoy-youre-all-pirates.hololivepro.com/)
**Anime and media work.** She performed the third opening theme of *One Piece Log: Fish-Man Island Saga* (TV, Fall 2024; listed by [MyAnimeList](https://www.edgepedia.org/myanimelist) as *One Piece: Gyojin Tou-hen*),[7](https://myanimelist.net/people/66647/Marine_Houshou) • [3](https://www.animenewsnetwork.com/encyclopedia/people.php?id=222999) and an insert song for the ONA *Marine Shukkō!!*.[3](https://www.animenewsnetwork.com/encyclopedia/people.php?id=222999) MyAnimeList further credits her as storyboard artist and theme song performer for *Kyapi* (2026), a credit that reflects her illustration skill.[7](https://myanimelist.net/people/66647/Marine_Houshou)
**Hololive stage releases.** Oricon credits her on charting hololive compilation releases: *hololive 3rd fes. Link Your Wish* (November 9, 2022; peaked 5th, 32 weeks on the chart), *hololive 4th fes. Our Bright Parade* (October 25, 2023; peaked 4th, 36 weeks), and the Blue Journey 1st Live release *夜明けのうた* (April 24, 2024; peaked 10th, 7 weeks).[6](https://www.oricon.co.jp/prof/772605/)
## By the numbers
**Subscriber record.** Her channel passed 1 million subscribers on January 18, 2021, 2 million on August 1, 2022, 3 million (and 3.01 million) on January 10, 2024, and 4 million on May 5, 2025.[5](https://dic.nicovideo.jp/a/%E5%AE%9D%E9%90%98%E3%83%9E%E3%83%AA%E3%83%B3) In February 2025 she stood at about 3.84 million subscribers, at that point the largest count within hololive's Japanese branch and among Japanese VTubers overall.[5](https://dic.nicovideo.jp/a/%E5%AE%9D%E9%90%98%E3%83%9E%E3%83%AA%E3%83%B3)
The headline superlative differs by scope across sources. Cover's own site claims the most YouTube subscribers of any VTuber in Japan,[4](https://ahoy-youre-all-pirates.hololivepro.com/) while MyAnimeList describes her as the most subscribed active VTuber worldwide, with over 4 million subscribers.[7](https://myanimelist.net/people/66647/Marine_Houshou) The official claim is the narrower of the two, and the broader worldwide ranking rests on the database's own framing rather than on Cover's materials.
**Chart and streaming figures.** On Oricon, *Ahoy!! キミたちみんなパイレーツ* peaked at 3rd and spent 26 weeks on the chart,[6](https://www.oricon.co.jp/prof/772605/) a stronger placement than any of the hololive compilation albums she appears on.[6](https://www.oricon.co.jp/prof/772605/) On Spotify she counts 438,959 monthly listeners, and *I'm Your Treasure Box ＊あなたは マリンせんちょうを たからばこからみつけた。* is her most-streamed track listed there at 21,141,140 plays.[8](https://open.spotify.com/artist/5XaBNKQo65yYcjNA8wQPOk)
## What has changed since 2023
**Releases and milestones.** Her milestones since late 2023 include the 3 million subscriber milestone on January 10, 2024 and 4 million on May 5, 2025;[5](https://dic.nicovideo.jp/a/%E5%AE%9D%E9%90%98%E3%83%9E%E3%83%AA%E3%83%B3) her first full album on October 16, 2024, which peaked 3rd on Oricon;[6](https://www.oricon.co.jp/prof/772605/) her first solo live, reported officially on December 6, 2024;[4](https://ahoy-youre-all-pirates.hololivepro.com/) and an anime opening theme, for *One Piece Log: Fish-Man Island Saga* in Fall 2024.[7](https://myanimelist.net/people/66647/Marine_Houshou)
**2026 activity.** The release *New World Carnival ～いざ魅惑の大海原へ■～* was released September 30, 2026, peaked at 12th on Oricon, and charted for 3 weeks.[6](https://www.oricon.co.jp/prof/772605/) She is credited with the ending theme of *Kabushikigaisha Magi-Lumière 2nd Season* (TV, Summer 2026) and the *Kyapi* storyboard and theme song credit the same year.[7](https://myanimelist.net/people/66647/Marine_Houshou) Spotify lists her latest single as *A Horny Money World ～伝説の夜～* and listed an appearance at LuckyFes'26 scheduled for August 8, 2026, at 国営ひたち海浜公園 (Hitachi Seaside Park) in Hitachinaka.[8](https://open.spotify.com/artist/5XaBNKQo65yYcjNA8wQPOk)
