Sinatys is streaming on Twitch to try and deal with shyness all while meeting new people.
On youtube, they are trying to produce content to practice spoken english, learn some basic editing skills, and build a community that share and understand their very particular and uncomfortable sense of humor c:
Sinatys does not feel confident and safe streaming alone at home, as people tend to easily make them uncomfortable. So they are playing in an arcade bar instead. The owner of the place provides moderation and watches peoples behavior for the streamer who does not like to manage people themselves. In return, the streamer helps the owner by working for her.
Their stream overlay shows the arcade machine they are playing on, and the owner behind the bar in the background.
