Personality

Cecilia is an intelligent streamer with a straightforward attitude. She can be stubborn and combative, and often uses sarcasm. She sometimes likes to trick her collab partners, but only in good fun. Her goal is to entertain her viewers.

She is exceptionally creative, and is known for programming unique "Immersions" in streams, whether shrinking her height to match the protagonist in Legend of Zelda, greenscreening herself into the game, or coding her own chat-controlled minigames. She is also noted for her musical talent, and plays violin well.

She is good friends with Gigi Murin, and the two form a comedic pair with Cecilia serving as the foil. Sometimes they're more like partners in crime.

Appearance

Cecilia is a clockwork automaton maiden. Her body is doll-jointed, and atop her head is a brass ribbon and clockwork key, which spins when she is excited. She has green eyes, and pale white-green neck-length hair. Her customary garb is an elaborate gold-trimmed off-shoulder dress with a red neckerchief, off-white sleeves and a green skirt decorated with musical notes and a clockwork motif. She wears sandals on her feet which give an ancient feel.

She is sometimes be seen wielding a white lance which transforms into a violin.

Background

Cecilia first learned of hololive through the infamous Natsuiro Matsuri 2019 band-aid clip. She has been a VTuber fan ever since. She followed hololive English since the first generation, and entered Mori Calliope's remix competition in 2020.

She applied to hololive on two occasions before being successful. In a multi-stage audition process, she was exceptionally nervous at the second stage, where she prepared a stream event. She describes it as a "very very silly" role-play event where she abducted staff. It was 4 am at her time, so she spent ten minutes dancing and spinning around for ten minutes to wake up and hype herself up.

Cecilia's YouTube account was created on 3 April 2024. Her Twitter account was registered in the same month.

Cecilia was announced as one of four members of hololive English -Justice- on 18 June 2024 in a video titled The Mission Begins! Cecilia made her debut Tweet shortly after. This was followed by a short profile video, titled [https://youtu.be/tbieD_vOfO4 Let this ensemble begin! 🎶 #holoJustice]

The announcement of hololive English fourth generation took most of the VTuber community by surprise. The previous English generation, Advent, had debuted less than a year earlier, and Cover's last quarterly report had suggested a strategy of less frequent VTuber debuts. The names of the new members had been leaked by trademark registration a few hours prior to their official announcement.

Prior to debut, the members of Justice recorded an audio series of "missions" where they visited a shrine to wish for a successful debut, visited a haunted house, visited a maid cafe, and met with FUWAMOCO for advice. The clips would not be released until December 2024.

Cecilia reached 100,000 YouTube subscribers prior to her debut.

Debut

Cecilia made her debut stream on 22 June 2024 at 8PM PDT. It featured a Twitch Plays Pokémon style chat-controlled game which she coded herself, and a violin performance featuring "Run" from Spice and Wolf and "A Beautiful Song" from NieR: Automata. The stream reached over 112,000 viewers at peak.

It was followed by a song cover premiere of Forgotten Words.

The Justice debut event concluded with the release of their first original single, ABOVE BELOW, and the first Justice collab on 22 June at 9:30 PM PDT.

Mascot and fans

Otomo
  • Her fan name is called Otomo/Otomos. Raora helped her design the mascot, which previously appeared in her Starting Soon screen carrying the teapot.
  • Otomo is a pun on "oto," Japanese for "musical note," and "tomo," Japanese for "friend." It's also a pun on "automaton."
  • On 9 August 2025, Otomo debuted its 3D model.
  • Cecilia was the last Justice member to select her fan name, as she wanted fans to help her come up with good ideas. "Otomo" was selected with 49% of the vote. Popular but unused suggestions for her fan name were Cranks, Immerlings, Immeralds, Automates, and Treblemakers.
  • She created the otomos to assist her with chores.
  • Her assistant is a clockwork bird, type bird_prototype_11.1. Its name is Ototori.
  • On 25 October 2025, Cecilia presented a chibi, bot version of herself called Immergold.

Relationships

Lore

  • She is referred to as the Ancient Automaton of hololive English -Justice-.
  • Her hometown is Immerheim. In German it means "Everhome."
  • She was created a long time ago. She doesn't age, although her outfit can change. However, she can still get sick if she isn't maintained properly.
  • She can also get drunk, because her creators thought it would be funny.
  • The key on her head spins when she thinks hard.
  • It can spin at two different speeds.
  • The key is her power source. If her head is separated from her body, her body can't move.
  • She worked for Justice for a very long time, even before it was officially founded.
  • Her violin transforms into a lance.
  • Justice has a headquarters in the clouds.
  • Her plan to capture Advent was originally to dig a big hole, but it was abandoned as ineffective, as Koseki Bijou can fly. Her second suggestion was to prepare rooms for them in Advent headquarters with all their favorite things. Once they are inside, she will remove the doors, hoping they won't notice because they're too busy streaming.
  • She has various alter egos:
  • She has an evil doppelganger named Cecilia Immerred. In her 2024 birthday stream, Immerred stole Immergreen's body while she was asleep, but was defeated when Chat helped to trap Immerred's soul in a jar. As of July 2025, she's still in the jar.
  • There is also a blonde variant who appeared as a barmaid on Oktoberfest, named Cecilia Immergold.
  • For Oktoberfest 2025, she debuted the Cecilia Immergold Bot, which she built because she doesn't like to work. It is an AI-powered bot.
  • She claims to have an assistant named Updatilia who posts to her social media when she should be asleep, or busy doing other things. Updatilia finally made an appearance in April 2025's Taxlady does your taxes, where she looks much like Cecilia but with a silver color theme.
  • Cecilia has a small spare doll body, but it lacks opposable thumbs.
  • Cecilia is often depicted as having known Elizabeth Rose Bloodflame since the latter was young, and even serving as her maid. For example, at the start of the music video for Cecilia's song Wind-Up, a girl appears wearing a bracelet matching one of Elizabeth's insignias. However, this is not necessarily canon.

  • She is only the second ever green member of hololive English, after Ceres Fauna.
  • Her bracelets and the large gear on her dress are engraved with an unknown script. The bracelets are mirror images of each other. The large gear is written such that it has rotational symmetry, so it would read the same if turned 180 degrees.
  • She shares her character illustrator with Amayui Moka of VSPO!, Appare Hinata of Weather Planet, Shirose Isumi of NIJISANJI, Anshinin Misa of Specialite, and Yuzuha Riko of StelLive.

  • She has various instruments, including a hurdy-gurdy.

  • In The Legend of Zelda: The Minish Cap, she made an animation to shrink her Live2D model in Minish Cap whenever Link shrinks.
  • In her second stream of Half-Life 2, she managed to carry Dog's ball all the way through Ravenholm, a difficult but useful task which allows it to be used as an effective throwing weapon. For subsequent streams she modded the game to re-skin the ball as a clump of Otomos, nicknamed Balltomo.
