- most of the early japanese utau
- all of the Yukailoids to some extent
- utoots that I can think of that have/had a crypton-ish design at some point: CRINA, Luna Ichine, Rena and Reizo Raine, Nilla Tohne, Taiyo Raikone, Sachi Eika, Stella Hoshine, Rana Sorane, Rina Utakawa, Satoko Chouwane, Shian Nanase, Kakou Higure (aaand many more ofcourse)
- Jakuon Kumone, Micro Sakurane, Tomi Samura - not the most crypton-ish, but they still have long detached sleeves and high boots
Akune Kin has a crypton-ish design. Ami Ichigawa's has been redesigned, but her older appearances were pure crypton-ish.
Now, slightly off topic, but not only the overseas UTAU users have an "obssession" (Couldnt find an appropriate word, srry) with making their UTAU crypton-ish and/or Full KEI style. If you enter NicoNico from time to time and search for "UTAU音源配布" or "音源配布", you'll see a bunch of UTAU heavily and clearly inspired by Crypton's VOCALOIDs.
