do tu know about other good vampire anime?

Ummm well here are all the animes with vampiros that I have seen, hope it helps :)

- chibi Vampire
- Blood+
- Fortune Arterial: Akai Yakusoku
- Kurozuka
- Tsukuyomi: Moon Phase
- Rosario + Vampire
- Shiki (Corpse Demon)
- Trinity Blood
- Hellsing
- Dance in the Vampire Bund
- Shingetsutan Tsukihime

and I haven't actually seen these three but they seem interesting and good...
- Blood-C
- Itsuka Tenma no Kuro Usagi
- Kizumonogatari

and I highly recommend this one if tu liked Vampire Knight... I loved it! :p (but this one doesn't have any vampiros tho)
- Uraboku (Betrayal Knows My Name)

Try Fortune Arterial Akai Yakusoku is very nice for me^^

nope i don't know any

karin-chibi vampire ..

tu could try Hellsing, although it's quite bloody and violent. There's also Trigun which is similar to Hellsing
