Having recovered from the injuries he had sustained, Zero returns to Cross Academy to resume his role as prefect. Though, not long after he resumes his role, members of the Supreme Vampire Council ambush Zero with the intent to execute him for the murder of the pureblood, Shizuka. Luckily when Kaname intervenes, he sends the council away and insists that they stay out of school affairs. However, whilst Kaname continues to hide the truth about Shizuka's death, there are others who grow suspicious of what happened that night and what the dorm president is hiding. Meanwhile, Yuuki begins to have flashbacks, leading her to investigate her blood-stained past: what will she find, and will she continue to be tempted by an offer from Kaname?
