I'm years behind but I finally played dark souls I and now I can watch her streams I've ignored for years to dodge spoilers.
Fun(?) fact: She has a kanataso101 playlist
https://www.youtube.com/playlist?list=PLNvxSJodVoAsAaBkGTosj5IBzIoga3Ful and it's the only game on there. Which I guess makes it her most important game? Unless you count the um@s gacha stream, which is not really a game (also I don't really get why it's there it feels very undeserving compared to the rest)
