Despite being a gifted hunter even at a young age, Zero was turned into a vampire himself, and thus has a difficult time thinking of himself or any vampire as anything but a monster. He is intelligent, athletic and good-hearted, but he struggles his desire for blood and his equally strong desire to kill vampires. This heavy burden has made Zero a very private person, making him difficult to understand or even be close to.
I do like how Zero looks in a Night Class’ uniform, but I remember he almost killed Kaien Cross for simply suggesting it. In any case, thanks to Yukina for sending this in!
