Cross Academy has two sessions, the Day Class and the Night Class; the latter consists of students who are beautiful, intelligent ... and vampires!

Shizuka suffers a wound. Meanwhile, Yuki and Zero try to find out where Shizuka may have gone, but Zero's constantly thwarted by his Level E seizures.

Yuki now understands who she really is. Worried about Zero, she sneaks out of her room to find him -- but he simply can't accept what she has become.
