Mori Calliope

This name is officially written using the Japanese name format, the family name is Mori.

Mori Calliope is an English Virtual YouTuber associated with hololive, as part of its English (EN) branch first generation of Vtubers alongside Ninomae Ina'nis, Takanashi Kiara, Watson Amelia, and Gawr Gura.

Personality
Calliope is equally excited by both rapping and "reaping". Her favorite weapons include her scythe (nicknamed "Ricky") and the flail, a medieval weapon made from a spiked metal ball on a chain.

Although fluent in English, Calliope often fails to understand current modes of speech, such as the use of contractions or modern slang. She is easily flustered by romance, leading some to call her the "tsundereaper".

When not on camera, however, she is described as air-headed and hopelessly forgetful as Kiara has mentioned that she typically misplaces her things over and over, despite leaving them in very obvious places like a cellphone in her jacket

Profile
The Grim Reaper's first apprentice. Because the world's medical system advanced so dramatically, Calliope became a VTuber to collect souls. It seems that the lost souls vaporized by the wholesome relationships of VTubers flow through her as well. In the end, she's a gentle-hearted girl whose sweet voice contradicts the morbid things she tends to say, as well as her hardcore vocals.

Background
She was introduced simultaneously on both hololive's and hololive's English Twitter accounts and on hololive English's YouTube channel in a small video with the rest of the first generation on 8 September 2020. Her Twitter account was created on July, but only made her first tweet on her official introduction on 8 September.

 * On 12 March 2021, as part of their six months celebration the holoMyth members announced that they would get an official BGM image soundtrack featuring Camellia, with a release date of 14 March. The song inspired by Calli is titled "Lively Bopping to Death's Knocking."

Fans

 * Her fanbase is officially called "Dead Beats" 「デットビーツ」

Quotes

 * "If you quit when you suck, you'll suck forever."

 * "We never forget the fallen, but we move on."

Trivia

 * In Japanese, her name is officially written 「森美声」. She also writes it with her given name in katakana,「森 カリオペ」, as on her Twitter and SoundCloud.
 * "Mori" is a Japanese surname, written with the kanji 森, meaning "forest".
 * Mori is also Latin for the verb "to die", as in such phrases as "memento mori" ("remember death"). This is referenced in her sign-off phrase: "I'm your Mori, and I hope you'll remember me." English words such as "mortal" are thought to derive from the same root.
 * The kanji used to write "Calliope" is 美声, normally read "bisei", meaning "beautiful voice". This is a calque of her Greek namesake, Καλλιόπη, which also means "beautiful voice" in ancient Greek.
 * In Greek mythology, Calliope is one of the Muses, a goddess who presides over epic poetry. It is normally pronounced "ka-LYE-o-pee" in English, which is how Calli pronounces her name. As such, Calliope's name is likely a nod to her singing voice as well as her passion for rap music, as poetry is the foundation of the genre.
 * When speaking in English, Calli usually gives her name in the English order, as does Amelia Watson. The other three holomyth members (Gawr Gura, Ninomae Ina'nis, and Takanashi Kiara) put the surname first, Japanese style, even when speaking English.
 * While many Japanese hololive members have a special pronoun for themselves (for example, Minato Aqua says "atishi", Nakiri Ayame says "yo", and Sakura Miko refers to herself in the third person), Calli is the only holoEN member who does something close to the English equivalent, sometimes referring to herself as "your boy".
 * She likes slaying people, dark spaces, flowers, stuffed dolls, sweets, the color red, mafia movies, rap (especially Japanese rap; she claims that she met the genre in the Underworld because it was dead), red wine, and “Death Sensei” (the Grim Reaper) as she is a reaper in training.
 * Because of her passion for rap, Calliope released an original song on her debut stream. She also announced that she would release her first EP for free to thank the support received, including four songs, an instrumental and an acapella version, some of them written by herself.
 * She dislikes crowds, coffee, hospitals and cantaloupe.
 * Her favorite animes include Puella Magi Madoka Magica, Made in Abyss and Dr. Stone.
 * Her favorite games include games from FromSoftware, Ghost of Tsushima, Castlevania: Symphony of the Night, weird RPG maker games, and platformers (preferring side-scrollers).
 * Because of her air headed nature, she has a bad habit of not knowing how to keep her mouth shut when she needs to, thus causing misunderstandings. For example:
 * She said she liked short guys because she wanted to make short people feel included as well as people with beards. This lead to her audience to think she has a fetish for short people and beards which she tried backpedaling on.
 * When asked about her cup size, she tried finding ways to avoid saying before using Shirogane Noel's "Knight Cup" idea for reference, not realising it to be an innuendo on K-cup bras. This has lead to her saying she is "Grim Reaper" Cup, which immediately backfired on her as everyone started to assume she's a D-cup, G-cup or even as extreme as an R-cup.
 * Her goals and dreams include becoming a great track maker and mixer, collaborating with other VTubers and people, supporting her fellow first gen members, becoming an expert in Japanese, writing and performing an anime or video game opening song, and writing a full album.
 * Calliope was the first member of hololive English to debut.
 * In addition to English, she can speak Japanese, although she is still learning and actively taking classes.
 * She claims that the Underworld mimics the aesthetic of the current era, so it looks mostly like a modern city.
 * Her debut stream experienced some lag. She claimed it was because of the bad internet connection in the Underworld.
 * She is the first hololive EN member and seventh hololive member overall to join official hololive Subreddit as a moderator.
 * She has a habit of randomly making comical gasping noises that sound like "guh", usually after taking a drink.
 * During her second live stream, Kiara revealed her crush on Calliope, much to Calliope's annoyance. This has to do with the fact that Kiara is immortal, so no matter how many times Calliope would kill her, she'd always revive. This has resulted in a long-standing running gag between the two, which eventually became the ship "TakaMori".
 * Her EP "Dead Beats" became the number one album worldwide on iTunes on 22 October 2020. This gave a lot of media attention to VTubers during a few days.
 * According to herself, before she became a Virtual Youtuber in the Human world, Calli worked two jobs, one of them a summer job at a restaurant chain as a waitress, in order to save up enough funds to take her dream trip to "Overworldian" Japan, and despite making quite a few mistakes during the Job, and being abused by more than one couple that entered, she stuck through it as long as she needed to. However, as soon as she was done saving up, and she had enough to buy the cheapest plane ticket she could find, Calli quit her Summer job and went on the trip she had been saving so long for.
 * Calliope made a guest appearance on the 23rd podcast video of Trash Taste, a podcast channel that consists of three Anitubers (Gigguk, CDawgVA, and The Anime Man). Among other things, she revealed that she is a big fan of MoistCr1TiKaL (penguinz0 on YouTube) and has expressed her desire to collab with him. She has also considered working with The Anime Man on rap.
 * Calliope's tweet about the Just Chatting stream after the new model announcement accidentally leaked the look of the new model due to it being scheduled before the actual reveal, which prompted an amusing remark from Watson Amelia.
