Rikka

Rikka (律可) is a male Japanese Virtual YouTuber endorsed by hololive's branch Holostars. He is a member of its first generation, alongside Hanasaki Miyabi, Kagami Kira, Kanade Izuru, Arurandeisu and (formerly) Yakushiji Suzaku.

Personality
Rikka is a Holoroid, an android 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. He says that he is equipped with high-performance AI, but despite that, he has 2GB of memory, making him prone to forgetfulness, and even has been described as an airhead by fans and fellow Holostars members.
