"The master of a hideaway bar: ROBEL. He streams before opening time. He talks to anyone openly, however it is hard to guess what he is thinking. Even though there are many chances for him to drink, it doesn’t necessarily mean he is a good drinker. His motto is: Men happily believe what they wish."
Roberu is an energetic host whenever he is streaming. He is very fond of RPGs and Gacha games, sometimes even attempting Gacha rolls on-stream. Although the Japanese fans refer to him as Master, given that he is a bartender, overseas fans regularly refer to him as "son". This nickname began after a Mario Kart stream where he read a comment that asked "are ya winning son?", to which he responded with a loud "YES, I'm Roberu Yukoku. I'm fine thank you, and you?".  Roberu hosts a morning free talk stream every morning on weekdays at around 10:00 JST. Some special streams on his bar include guests from the Hololive JP and ID branches, fellow Holostars, as well as outside from Hololive, such as VA's and Indie Vtubers.
