A deadly hybrid of a ninja
and a vampire
. Pissing one off or having delicious blood will ALWAYS result in death. Sometimes, they will kill you just because they don't like you or they are hungry. Ninpires are not always ninja-ing around and can appear as a regular human, which makes them very difficult to identify.
Kristin: Guess what?

Linden: Wtf is that?
Kristin: Part ninja part vampire
Linden: Pfft there's no such thing
Kristin: DEATH BECOMES OF YOU!
Kristin: **sucks Linden's blood, then kills her in a ninja manner**
