Siro's introduction.

Personality and History

Starting the activity at the dawn of Virtual YouTuber, Siro became one of the "big four" of Virtual YouTubers (VTuber). She calls herself "neat and clean" but it is different from the original meaning, for Siro is good at playing PUBG and while playing, she sometimes says terrible comments as if she were a soldier or a combat mania. In addition, Siro is very good at speaking English, as she studied it. She is also funny in her videos. She loves to dance and talk tenderly in her videos. Beluga is her famous symbol. Her laughing voice is similar to the sound of dolphins (イルカ iruka). She is called "White dolphin" (シロイルカ Shiro Iruka) namely Beluga. Virtual YouTubers tend to have their own greeting phrases; in her case, she says "Konnichiwa. Siro desu." (Hello. I'm Siro.)


On 6 July, the VTuber-only movie, Sirotsumekusa (白爪草), was announced, with Siro being revealed to play the twin protagonists,[1] later revealed to be named Shiratsubaki Aoi and Shiratsubaki Beni.[2][3] The movie was released on 19 September.[4]


Siro has several appearances. Her current one is the one which she wears a blue snow jacket with a matching blue hat. Her other appearances are similar to a goddess, while another is with a blue skirt.

As of August 12, 2019, on her 2nd year birthday, Siro's model was drastically changed.
