Kaname x OC

Mirei has arrived at Cross Academy, a school which is home to both humans and vampires. But what most don't know is that Mirei is not only a vampire but a Pureblood, a powerful vampire with no traces of human descent. She is attending Cross Academy as a member of the Day Class and is pretending to be human, however there is another Pureblood at this prestigious school, Kaname Kuran who is becoming suspicious.
