A creator on Nico Nico Douga and YouTube. Would be most known for his characters Sayo-chan and Ono-chan, debuting in 2013. Sayo in particular would, following the rise of virtual YouTubers, be credited as one of the Pioneers in the field, alongside others such as Chiyu 12-sai (debut 2001), Ami Yamato (debut 2011), Weatheroid Airi (debut 2012), and Infinite Loop's ILtan (あいえるたん).
Would go on to create the VTuber Virtual Obaachan in early 2018.
