Rikka's introduction.


Rikka 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.


A robot (holoroid) 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 steaming, even though sometimes he suddenly bugs out and becomes awkward.[1]



His Twitter account was created in 18 September 18 2019; his YouTube channel was created on the same day, and his debut stream was performed on 20 October.


On 21 October, Rikka released his first cover song, Dakara Boku wa Ongaku o Yameta (That's Why I Gave Up on Music) by Yorushika.[2]

The song then became available on iTunes on 5 September and became available on other various streaming services on 8 September.[8]

On 7 July, he reached 40,000 subscribers.[9]

On 9 July, he hosted the first episode of his new series called "RiTunes Labo", where he invites guests, such as fellow VTubers and voice actors, to sing with him online, accompanied with Rikka's guitar playing. He uses a software called SYNCROOM enabling him and the guest to be in sync with each other with little delay when singing together. The playlist of the series can be found here. His first guest was his fellow VTuber Amenosei.[10]

On 4 August, he revealed his summer costume.[11]

On 13 August, he reached 50,000 subscribers.[12]

On 3 September, he opened his membership feature.[13]

On 20 September, he reached 60,000 subscribers.[14]

On 25 October, he reached 70,00 subscribers.[15]

On 28 November, he reached 80,000 subscribers.[16]

On 25 December, it was announced that all the Holostars members would receive new costumes on 3 January, 2021, commemorating New Year's.[17] On the same day, he reached 90,000 subscribers.[18]


On January 3, he revealed his new year's costume,[19] which was modelled by vivi.[20]

On January 17, Rikka reached 100.000 subscribers during an endurance singing stream, being the second Holostars to reach this milestone.[21]

On 25 March, in his concert "Over the silver dawn" commemorating his milestone of 100,000 subscribers, he sang two new original songs, a duet with Mori Calliope called "Spiral Tones" and a solo called "Archive". Later in his fifteenth edition of RiTunes Labo featuring Calli, they announced that a MV for "Spiral Tones" is in the making.[22]
