Sou is a younger generation Utaite, who began uploading songs in 2013. He has a calm and refreshing voice that he can utilize to fit songs that he sings. Usually, Sou will sing in an expressive and emotional tone to set the mood of a song, such as in his "Kokoronashi" cover, in which he sang in a rather sentimental and lonely tone. As such, Sou often has 'Refreshingly' or other adjectives describing his singing in the beginning of his video titles to emphasize his takes.

By making multiple songs and singing various covers, Sou has found more collaborative opportunities with other utaite, such as with the utaite Eve. He is close friends with Eve and Isubokuro and they often collaborate together, forming units named "Soborogohan" (そぼろごはん) and "EveSou"(いぶそう).

Growing larger in popularity, Sou has participated in multiple live concerts. A notable example being that Sou performed at the 2019 HikiFes live concert, singing the theme song World Domination and other songs as well.

As of May 2021, Sou's most viewed video is "Harehare ya”, with over 60 million views. The song itself is a slow, traditional styled beat. Sou's version of the song matched the music well, leading the cover to become a huge success.

On 31 May, 2021, Sou made his Virtual YouTuber debut by debuting his 3D model in a non-archived stream.[3]. He now has a second channel for livestreams too.[4] Read more on Last.fm. User-contributed text is available under the Creative Commons By-SA License; additional terms may apply.
