Kageyama Shien

Kageyama Shien (影山シエン) is a male Japanese Virtual YouTuber endorsed by hololive's branch Holostars. He is a member of its third generation alongside Aragami Oga, which was previously known as "TriNero" (トライネロ) prior to Tsukishita Kaoru's retirement. Shien and Oga then became known as "MaFia" (魔フィア).

Profile
A mafia boss from the land of beastmen.

Came to our world in search of his missing best friend.

Was scouted by Shinove after coming to a standstill in his search.

Acts tougher than he really is but doesn't have the talent to be truly evil.

Personality
Shien is a jackal that sometimes can be quite dumb and naive, baby-like, even. Former TriNero member Tsukishita Kaoru described him as a man that misuses his handsome voice, and "if a bat maker gave him the world's best baseball bat, he'd use it for soccer". Additionally, Aragami Oga, another member of TriNero, states that despite him being a mafia boss, he can't do anything without his subordinates. He further states that despite having good ears, he doesn't seem to listen to anyone.

Background
His Twitter account was created in 10 April 2020; he made his first tweet on 27 April, his YouTube channel was created on 8 April, and his debut stream was performed on 30 April.

2020
Shortly after his debut, his Twitter account was suspended because of his birth year being set to 2020. On 2 June, the Twitter suspension was lifted.

On 16 August, he released a cover of Fire◎Flower by halyosy, in which he sang with Rikka, Kanade Izuru and Astel Leda, making it his first cover song.

On 27 September, he released his first solo cover song, KING by Kanaria.

On 25 December, it was announced that all the Holostars members would receive new costumes on 3 January, 2021, commemorating New Year's.

2021
On January 3, he revealed his new year's costume, which was modelled by Klaeia.

On 9 January, he opened his membership feature.

On March 20, Shien reached 100.000 subscribers, being the third Holostars to reach this milestone.

On 7 July, he announced that he will receive his 3D model, and that a 3D stream would be performed on 10 July.

Trivia

 * He likes anmitsu, as well as omurice.
 * He dislikes oysters.
 * His favorite animal is the kuroshiba.
 * In the process of creating TriNero's Twitter accounts, they were cautioned seriously by Daidou Shinove, Holostars' manager, and mentioned that they had to be careful with the birthday settings, as your account would get locked if you were underage. Aragami Oga joked that because they debut in 2020, that would also be their birth year, which may have caused Shien to set 2020 as his birth year, thus causing his Twitter suspension.
 * Shien's Twitter suspension has caused jokes between fans, saying that he was baby, as if he was born in 2020. Notable examples of the joke was when Shirakami Fubuki drew Shien as a baby, Aragami Oga displaying Shien with a pacifier in his mouth, as well as calling him a "babbling baby" in his debut stream, and Tsukishita Kaoru making Shien's drink a baby bottle in the first TriNero collab.
 * Along with that, because his Twitter was suspended, he couldn't set up his official fan mark, but the official Holostars Twitter confirmed that "🟣", a purple circle, was his fan mark, shown in schedules. However, fans used "🍼", a baby bottle, as an unofficial fan mark as part of the joke.
 * Ironically, he is lactose intolerant.
 * Fans have stated how Shien's voice is very similar to that of voice actor Takahiro Sakurai's. Shien has even done some impressions of characters Sakurai has voiced, for example, Lucio from Granblue Fantasy.
 * His fetish is asses without thigh gaps, as when the legs are closed, it jiggles due to the "fleshiness".
 * One of Shien's running gags is him using an echo filter on his mic, often at abrupt times.
 * He shares the same character designer with Shirayuki Tomoe from Nijisanji.
 * He owns a toy sword called DX Kageyama Blade (DX影山刀) that comes with various voice lines, voiced by himself. Some of the voice lines include his stream greeting and ending lines as well as original special attack names.
 * Sometimes new viewers mistake him as a dog, cat or even a skunk.
 * During his birthday stream, he revealed that when he hit around 20 years old, he went drinking without knowing his alcohol tolerance. He merrily went to an izakaya, had six cocktails of Kahlua Milk and vomitted so much he puked blood soon after, causing the realization that he can't drink, only able to do so moderately.
