Domyoji Cocoa (道明寺ここあ) is a female Japanese Virtual YouTuber. She is the younger sister of Domyoji Haruto from the Game Club Project.
Her channel was created on 9 July 2018, but she didn't uploaded a video until 24 July, with a cover of the song Rising Hope, however this video was deleted, due to the use of some scenery not intended for that purpose.
Departure of the original voice actress
On 9 December 2019, the original voice actress of Cocoa, concluded her activities with a stream on YouTube. 
On 9 March, Cocoa's agency Unlimited published a statement in their website and Suzuki Midori's Twitter account announcing the restart of Cocoa's activities. Unlimited explained that Cocoa's original voice actress left to pursue other goals and, after some consideration regarding Cocoa's voice, they decided to hire a new voice actress for her with a different personality.
This time however, and unlike with Game Club Project's voice actors replacement controversy, the new Cocoa will return in a new channel, in what appears to be an attempt to respect the original performer's legacy and memory with the fans. Cocoa redebuted on 13 March with a cover of the song ETERNAL BLAZE.
On 19 September, Cocoa released her very 1st single called "Fall in Sunset". Written by Mikito-P.
Currently under the agency, Riot Music, along with 4 other girls.
