halfey, Waifus I'm tired of: Touhou, Vocaloid.
Waifus I used to like but not excited about anymore: KanColle.
I don't care about: VTuber (don't see them as seiyuu either)
Waifus I'm currently into now: Anyone who isn't from the above, and no one from Naruto/Bleach/One Piece/Hero Academia/Demon Slayer (or any long running series; no offense to anyone who likes those titles). Bonus points if they are voiced by my favorite seiyuu.
Those from Isekai Quartet are among my favorites.
