Nina Kosaka

Nina Kosaka (狐坂ニナ) is 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
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.
