Let's update it right now. Everyone on the JP side has new records lol and Hestia went from near the bottom to like top 5. Official list of longest VShojo streams ever. The power gap between Nagi and everyone else is ridiculous and I do not see anyone approaching her record anytime soon. And they shouldn't try because that was wildly unhealthy of her lmao.

Note that this is NOT including:
-Streams that set out to be a specific length from the outset (ie 24 hour stream!)
-Streams that were part of a subathon
-Stream VOD replays, which Twitchtracker apparently tracks for some reason
