>>29842278>high energy but can do long endurance gaming streamsNene is high energy and can do longer streams. She streams 7+ times a week so she puts in the hours you are looking for. She plays a lot of games but isn't very good at them but she always stays positive.
Shee is also a good pick for this she is very bubbly and very excitable but she recently got a job and her internet has been dying lately so her streams have been on the shorter side (Still ~3 hours).
>someone chill I can put in the background that has interesting anecdotes.Namiji is very chill and her streams are filled with anecdotes. Her art/rigging streams are the best source of them with the bonus you don't usually need to focus on what she is doing.
I don't have the chance to watch her live as much but Lua is also very chill, her zatsudans have a lot of anecdotes about living in Japan and general girl stuff if that interests you.
Charzu, Isla and Reina are also great check them out too. Also stay tuned for the debuts of gen 3 which should be coming soon.
