There's just four in my "collection" (if you can even call it that) but I'm really proud to have them. Nana Mizuki has been in my wishlist for over a decade; Bocchi was my surprise find during a memorable Tokyo trip. Sakura was my other forever wishlist, and Takina is a guilty splurge. Won't be adding anyone new in the near future but seeing them makes me feel accomplished, lol.
