Activities

Streaming style

His channel description says he wants people in both the VTuber world and the psychiatric and medical field to learn more and have a good experience. He uses stream titles to separate content types. Streams whose main purpose is to share information about psychiatric care or sleep have "Psychiatric Care" or "Sleep" in the title. All other streams are for other purposes, such as entertainment.

He treats streams as having an on and off mode. When he wears his lab coat, he gives serious talks in a lecture style. Without the coat, his streams are casual and meant for fun with viewers.

Characteristics

As a character, Hitotsubashi is a super elite psychiatrist with many patients, and he spends each day talking with patients about their worries. He has short grey hair and brown eyes. He wears round silver-framed glasses and a white doctor's coat over a grey shirt. Coverage of his debut noted that he seemed quite nervous despite his cool look. He is very fond of ramen, which comes up often in his talks, and a ramen emoji appears in his channel description. His character designer, RIZ3, also designed Scarle Yonaguni of NIJISANJI EN.
