Introduction Video[edit]

Official Bio[edit]

"A robot created FOR Holostars. As he loves to learn new things, he absorbs all sorts of information from databases and the Internet. He is also interested in human beings, which is why he started streaming, even though sometimes he suddenly bugs out and becomes awkward."


Rikka (Rikkaroid) is a 1st generation member of Holostars, a branch affiliated with Hololive. His youtube debut was on Oct. 20th, 2019[10]. He generally streams or uploads videos that are music or game based. He has a softer sounding voice with a wide vocal range.


Rikka is stated to be an airhead, but he does not admit to it, even after forgetting what his fanart tag was for, as well as his own fan name. He gets along with the other members of Hololive Production, as well as other Vtubers. He has nicknames for the members of Holostars as well as some others. Rikka prefers if others call him by a nickname or without honorifics, as he does not like the -san honorific.
