Nina Kosaka

Nina Kosaka was a female English Virtual YouTuber affiliated with NIJISANJI EN's third wave "Ethyria", alongside Millie Parfait, Enna Alouette, and Reimu Endou.

Profile
A nine-tailed fox that presides over the heavens. She wishes for the joy of all souls on the long journey.

Personality
Nina is known as the "mom" of NIJISANJI EN due to her doting, supportive behavior. Other Livers generally regard her as a trustworthy person who will lend an ear to their troubles. Nina often refers to her fellow Livers as her children and goes out of her way to support new EN members early-on. Her streams have a reputation among viewers for a comfy, healing atmosphere.

From time to time, Nina presents herself as a "boomer," (or more accurately, Generation X), who is not very well-versed with the Internet, such as claiming to still use Internet Explorer as her main browser or prefixing the names of social media websites with "the" (e.g. "the Facebooks", "the TikToks", etc.)

Despite her nurturing personality, Nina also has a cunning, borderline sadistic side to her. This typically manifests through her dark sense of humor, such as claiming that she would sell Finana Ryugu for a few bottles of wine, trying to capture 200 penguin-like creatures in Subnautica due to their resemblance to Petra Gurin and place them in a Bioreactor unless she reached 200k subscribers first, or calling her viewers "pathetic" for refusing to sacrifice their lives for her sake.

Background
Nina originally learned of VTubers when she discovered Ironmouse and Veibae. She first discovered NIJISANJI by actively searching for male VTubers.

On 18 June 2021, NIJISANJI EN opened two sets of auditions, one of which was for an all-female wave of four. Sillouettes of the new Livers' designs were shown, one of which was designated "Fox of Heaven." The all-female auditions lasted until 11 July. Youtube channels for NIJISANJI EN's third wave were created on 14 September 2021, and their Twitter accounts were also created in September 2021.

On 5 Oct 2021, NIJISANJI EN announced the upcoming debut of its third group, "Ethyria," revealing a teaser featuring the new Livers' full designs and voices.

Debut
Ethyria made their debuts on 9 Oct 2021 (JST) as part of a special debut program hosted on the NIJISANJI EN channel, with commentary provided by OBSYDIA. Nina was the first of the group to debut.

Afterwards, all four members of Ethyria joined the main channel's special program to receive OBSYDIA's congratulations. Ethyria's first original song, "God sees all", premiered shortly after the program. This song was written and produced by ChibiNyan.

The instrumental and lyrics were done by KagamiFuri, mixing was done by VESEN, the MV was done by tanbearine, and illustrations were done by Amicia Michella.

On 27 November, Nina revealed her new outfit, nicknamed "Queen of Diamonds." She wears a black-and-red dress with a red spider lily motif, a gold corset with a tied red cord and thin gold chains around her waist, long black gloves, and a diamond choker. Her dress has a slit opening on one side, revealing black thigh-highs with garterbelts. She also wears gold chain bracelets and anklets with diamond-shaped links. She sports long, straight hair and hime-cut bangs, and wears a red spider lily in her hair. As part of Ethyria's queenly theme, she wields a black and gold staff with a winged fox. This ouftit features several other accessories, including a fancy black hat with holes for her ears, a black lace mask, a tattoo of herself on her upper chest, and a fox mask for her sentient tail mascot, Robert. Shortly after her outfit reveal, Nina premiered a solo metal cover of "God Sees All." Later, new goods went up for sale to celebrate Ethyria's new outfits.

Retirement
On 26 June, it was announced that Nina would retire from NIJISANJI EN on 8 July. Initially, it was stated that her YouTube channel, Twitter, and other social media accounts would be made private after her graduation, and the sale of her merchandise and voice content would eventually stop. Nina later announced that her YouTube content would remain online indefinitely.

On 7 July, Nina held her graduation stream, which consisted of chats with other NIJISANJI EN members. It attracted over 32,000 viewers at peak, and lasted over 10 hours, necessitating an immediate second graduation stream which continued for over 7 hours and rose to over 50,000 concurrent viewers by the end, for a total of 18 hours consecutive streaming.

Nina is the first NIJISANJI EN liver to have a graduation stream, as previous members either graduated without one (Yugo Asuma) or were terminated (Zaion LanZa).

On 26 July, Nina's channel reached 600,000 subscribers after her graduation.

Identity

 * Title: Fox of Heaven
 * Color: #660000

Lore

 * Nina was a normal fox who died and went to heaven, but was kicked out in 2021 for a variety of mischief, including thievery and drunkenness. She rankled against the boring, unchanging and highly bureaucratic rules of heaven.
 * Returning to Earth as a fox spirit, she took humanlike guise. She had to take a series of menial jobs, so her hands are much older than she is. She is self-conscious about this, and wears gloves as a result.
 * According to the About section of her YouTube channel, Nina served heaven as a keeper and bestower of luck. She was kicked out for giving out too much luck and wealth, upsetting the balance of the world. She was stripped of most of her powers and sent to Earth, gradually atoning by serving as a beacon of luck to humanity.

Mornings with Fox Mom

 * Nina ran a running series of one-on-one zatsudan collabs with other Livers, including some from outside NIJISANJI EN.
 * Her guests so far include Luca Kaneshiro, Mysta Rias, Elira Pendora, Mika Melatika, Rosemi Lovelock, Aster Arcadia, Ban Hada, Kyo Kaneko, Millie Parfait, Aia Amare, Sonny Brisko, Ike Eveland, Pomu Rainpuff, Alban Knox, Scarle Yonaguni and Maria Marionette.

Miscellaneous

 * She had to purchase an alarm clock to prevent oversleeping. Her stated record is 16.5 hours.
 * She is talented in making a "gremlin voice."
 * She enjoys cooking and drinking wine.
 * She gets scared easily and screams very loudly and at a very high pitch.
 * Although Nina's height change to 174 cm was initially claimed to be due to fox magic, Nina would later claim in a reply to Mika Melatika that management initially measured Nina's height incorrectly (blaming the wine for the error). This would be corrected upon remeasuring.
 * Her rice purity score is likely the lowest in NijisanjiEN. Though the exact score has not been made public, her score was even surprising to Aia Amare, who already has a low score of 23. Her score is thus likely below 20.
 * She is fluent in English, Russian, and French.
 * Due to her proficiency in Russian, a relatively large portion of her fanbase is Russian.
 * She has done chat streams where she exclusively speaks either Russian and/or French.
 * She sometimes mispronounces some words because she received an education based in French rather than English. In some cases, she uses the wrong pronunciation deliberately, such as pronouncing "mistake" as "mistacky."
 * When Nina first joined NIJISANJI, she would spend many hours in Discord chatting with Mika Melatika and Oliver Evans.
 * Nina became a fan of the Metal Gear franchise after being introduced to it by fellow NIJISANJI EN member and noted Metal Gear fanatic Pomu Rainpuff. Although Nina streamed the first three Metal Gear Solid games, she was unable to complete her Metal Gear Solid 3 playthrough prior to graduation. Nina had previously stated her wish to replay the games later in the year.
