Kaien gives Yuuki a protection bracelet that would stop Zero if he attempts to bite her again. A new ethics teacher, Toga Yagari, joins the school, and in his first class, Zero leaves. In the town, a Level E vampire attacks Yuuki and Zero, and they are saved by Night Class students Takuma Ichijo and Senri Shiki, who explain that they were hunting the Level E as part of their duties as noble-class vampires. Takuma invites Yuuki and Zero to his party, in which Kaname explains to Yuuki the continuing battle between vampires and vampire hunters. Zero, uncomfortable by the presence of so many vampires, leaves. Yuuki follows him and Zero attempts to bite her. Yuuki pulls Zero into a pool, and Yagari, revealing himself as a vampire hunter, shoots Zero in the shoulder.
