Kingdom of Knuffel

Toya Kano from Millennium Snow. He is an anemic vampire because he doesn't like drinking blood. XD
But it's part of what makes him cute.

Staz from Blood Lad (Otaku vampire - hilarious)
Alucard from Hellsing (I am all for crazy vampires)
Anzai from Devil Lines (he's cute)
Ruki from Diabolik Lovers (the only non-sadistic one)
Jirou from Black Blood Brothers (I just love him)

Cadis Etrama Di Raizel (Noblesse)

I like Kiss-shot Acerola-orion Heart-under-blade from the Monogatari series. She is cute, wise and strong. I really like her character development throughout the series.
