Season 1

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

Yuki is busy patrolling the school grounds for Day Class girls who are trying to sneak chocolates to the Night Class boys for St. Xocolatl’s Day.

When Zero suddenly leaves the school grounds, Yuki goes after him and roams the streets alone, until a mysterious mother and child appear before her.

Seeing the state Yuki is in, Kaname takes her from Zero, who is speechless when he realizes what he has done. Yuki cries, unaware of Zero’s secret.

A new ethics teacher arrives at Cross Academy. His atypical looks are all the buzz among the Day Class; even Zero has lost his usual composure.

Zero is tempted to sink his fangs into Yuki, and even though he's able to regain his composure, he finds himself the target of a teacher.

Yuki makes a decision regarding Zero, who is determined to fight his affliction until the very end. Yuki feels guilty for betraying Kaname.

There's a commotion in the Moon dormitory when the Night Class gets word that Takuma’s grandfather, a figure in the vampire world, will be visiting.

Day Class students are chasing after the Night Class due to the upcoming dance. Meanwhile, the Headmaster asks Yuki to show a transfer student around.

Zero tutors Yuki for an exam, but all the while something is wrong with him. Meanwhile, at the Moon dormitory, Kaname confronts Maria in his room.

Maria’s masked servant reveals himself as a jealous figure from Zero's past whom Zero has not seen since their separation long ago.

Yuki learns Maria's true identity. With this new information, Yuki accepts a deal to offer her blood in order to save Zero.

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.
