If you're open to watching vtubers outside of Hololive you ought to be open to watch vtubers outside of Nijisanji as well. By combining your possible viewing options with not just Hololive and Nijisanji, but also everyone else, you can truly be diverse in your selection.
Sure Aia has DnD discussion streams, but she does not run Blades In the Dark or Lancer with other vtubers.
Sure Nina plays Crusader Kings 3 and Satisfactory, but she does not play Dwarf Fortress on-steam.
Sure Enna and various Nijis have handcam streams, but none of them thus far done multi-stream knitting streams and tarrot readings with IRL cards.
Sure Petra has piano streams, but she does not do it every other day and makes it her staple content.
That goes for Hololive too.
If you want something very specific and very niche, you're better off seeking specific vtubers that does that ONE THING and mostly only that. Bigger vtubers tend to mix things up unless it's fucking Apex legends.
