Career

Rikka was first teased in a press release dated 2 September 2019. The same release also announced Arurandeisu and Yakushiji Suzaku as new HOLOSTARS members. His Twitter (X) account and YouTube channel were both created on 18 September 2019. On 17 October 2019 he was officially announced as the sixth member of the HOLOSTARS first generation, and he held his debut stream three days later, on 20 October 2019.

His fellow first-generation members are Hanasaki Miyabi, Kagami Kira, Kanade Izuru, Arurandeisu and Yakushiji Suzaku. He was the last of the six to be officially announced. Besides his main YouTube channel (Rikka ch.), he runs accounts on bilibili, TwitCasting, TikTok and Twitch.

Activities

Streaming style

Music is central to Rikka's activities. His official profile describes him as working hard to share his songs with people around the world. Profiles also say that because he considers himself poor with words, he prefers to express himself through music. Singing is a large part of his content, and observers often point to the contrast between his gentle speaking voice and his singing voice as one of his main appeals.

Profiles also describe him as a very strong Tetris player and say he has a high tolerance for alcohol. Since he streams on several platforms, including YouTube, Twitch, TwitCasting and bilibili, he can reach audiences both inside and outside Japan.

Characteristics

According to his official HOLOSTARS profile, Rikka is a "high-tech" robot known as a holoroid. It later turns out that his memory capacity is only 2 GB, so he is somewhat of an airhead. In his character, this forgetfulness is played for its endearing side. His profile also highlights the gap between his soft talking voice and his singing voice as particularly charming.

Profiles describe him as young but mature, and as one of the more reliable members of HOLOSTARS. He is also described as eager to learn and to share music with a wider audience.
