Hoshimachi Suisei

Hoshimachi Suisei (星街すいせい) is a female Japanese Virtual YouTuber. On 19 May, she joins Inonaka Music, a music label under hololive, along with AZKi.

Personality
Suisei is a modest, multitalented girl who is among the more level-headed members of Hololive. However, after her unexpectedly compelling performance as a traitor in a game of Project Winter, she gained a reputation for remorseless sociopathy behind a facade of polite sweetness. No one seems to know how much of the "Psychopath Suisei" persona is real or not, but Suisei herself acknowledges the comedic potential of the joke and has referred to the incident on multiple occasions.

Background
Her Twitter account and YouTube channel was created on 18 March 2018. Her introduction video was uploaded four days later on 22 March.

On 1 July she became a member of a VTuber group called gnal. On 4 August, a month later, she announced on Twitter about graduating from the group and resuming her activities as a solo idol a week later.

2019
On 19 May during AZKi's first live, she appeared as a surprise guest performer where she performed her second original song "天球、彗星は夜を跨いで" (Tenkyuu, Suisei wa Yoru wo Mataide) after it was announced that AZKi and Suisei would be affiliated with Inonaka Music (INNK MUSIC), a music label under hololive.

On 27 July, she along with AZKi will participate in INNK EXHiBiTiON, a label event hosted by INNK MUSIC. It will be held at Entas in Akihabara.
