Introduction Video



Polka's introduction.

A circus performer who joined hololive in hopes of becoming the ringmaster of the VTuber world.

She enjoys wowing audiences with acrobatics, and she lives by the words, "When you've decided you're gonna do something, follow through!"

Her natural charm glosses over her occasional mess-ups.[10]
A circus performer who joined hololive in hopes of becoming the ringmaster of the VTuber world. She enjoys wowing audiences with acrobatics, and lives by the words, “When the going gets tough, the tough get going.” If you ask her, her occasional mess ups are also part of her charm.[11]


Polka is known for her silliness and spunk. As a natural-born joker, the only thing to be expected during her streams is unpredictability. In short, rather than simply being referred to as a clown, like she truly is, she’s more often called the entire circus by her fans. True to her nature as a circus performer, she is very energetic and outgoing. As seen on various of her streams and 3D performances, she has a distinctive laugh that can be compared to Pekora's. She also has an array of various instruments at her disposal (which include but are not limited to: bells, rotary phone, glockenspiel, vibraslap, and rubber chickens).

Despite these traits, she is often at the receiving end of pranks and teasing from fellow hololive members and her chat.

She prefers her audience to shout "Poruka Oruka?" (Where's Polka) on her loading screens so she may greet her audience with "Poruka oru yo!" (Polka's here!).



She was introduced on hololive’s YouTube channel in a small introductory video along with the rest of the fifth gen on 6 August 2020.[12] Her Twitter account was created in June 2020, she made her first tweet on 6 August.[13] Her YouTube channel was created on 5 June, but she didn’t debut until 16 August 2020.

Polka no Densetsu

Polka no Densetsu 「ポルカの伝説」(Legend of Polka) is a series of videos that aired every Thursday from 29 April 2021. According to the hololive English official Twitter feed, the show starred Polka and rookie staff member Izutsu-san as they "descend into studio recording hell."

The show starts with Polka in an empty room, when Izutsu-san brings something for Polka to do or react and respond to, such as manga Polka made in her childhood, or kids asking Polka for advice in various topics. Throughout the show, Polka interacts mostly with Izutsu-san or any guest she might have brought.

The show ended on 30 September 2021 after 24 episodes, but was renewed for a second season.

  • On 25 Febuary 2021, Polka was made playable in Disgaea 6 in Japan as a Circus Mage named Pol-Pol along with Rushia, Flare, Watame and Fubuki.
  • On 26 June 2021, Village Vanguard Twitter account announced that the members of hololive 5th Gen, would appear in limited edition goods with "Kemonomimi Cafe" as the theme.[38]
  • On 1 October 2021, Pupuya Games announced that Polka would be voicing the boss character Tania in their upcoming game Little Witch Nobeta, cast alongside Fubuki and Noel.[39]


  • Her fanbase is officially called "Omaruza" 「おまる座 」.[40]


  • Polka's surname Omaru「尾丸」can be divided as such,
    • The first kanji「尾」can be read as "O/Po/Bi" which means "tail."
    • The second kanji「丸」can be read as "Maru" which means "round/circle."
    • So her surname can be translated as "Rounded Tail."
  • Polka is a fennec girl, and according to her, her grandfather was a fennec fox too.[41][42]
  • She likes garlic, and hates gravity and humidity.
  • Her favorite anime and manga include: Aikatsu, Pretty Rhythm: Rainbow Live, The Melancholy of Haruhi Suzumiya, Revue Starlight, Re:Zero, Blue Period and HUNTERxHUNTER.
  • She is not very good at video games, but likes free-short games, TRPGs, and horror games. She also wants to try playing retro games.
  • She is noted for her stamina, hosting 3-hour long karaoke streams with hardly any breaks.
  • She has multiple shapes inside her pupils, hearts and stars appear when she is happy, clovers when she is sad and spades when angry. All these shapes are suits in playing cards, with the exception of having stars instead of diamonds.
  • She often complained about her outdated desktop, which leads to western fans calling her desktop a “Poltato PC” (portmanteau for Polka & Potato). She later bought a more powerful PC, which she referred to as her "Beef PC."
  • Despite being a circus performer, she is not good at juggling or walking on thin beam/wire as shown in her 3D debut and one episode of holo no graffiti. Instead, she is known for demonstrating various voices in her videos, streams and singing, even using seven voices in one video.
    • If anything, Polka's "performances" resemble something out of Rakugo, a minimalist traditional style of comical storytelling, granted in a more internet style. This is further expressed by how she makes the most out of the smallest things, such as changing her voice to echo when she enters a cave in a game, having small props (such as rotor phones) at arms reach to sell her jokes or having a convincing conversation with herself on stream.
  • She occasionally displays poor sense of direction when playing games, such as getting lost in Phasmophobia despite being guided by other players, or frequently strayed in Minecraft collaborations whenever she lost sight of her companion.
  • Despite calling the Cover CEO Tanigo as Yagoo and making fun of him just like others, she is the only one to consider him as friend, and vice versa.
  • As revealed in the first episode of the "Polka no Densetsu" series, she drew her own manga "Magical☆Toki" when attending 5th Grade in primary school, which was revisited by herself in the episode. Polka has even created a theme song for it and used the song as the ending theme of that episode.
