Burden of Sinners ~Guilty~.
While separating the Day Class students from the Night Class students to allow them to go to class, Yuki Cross accidentally calls Zero Kiryu as Kaname Kuran, which later disappoints him, as he has just returned from recovery. That evening, Maria Kurenai awakens and confuses Zero for Ichiru. She tells Zero that Shizuka Hio was seeking the Pureblood vampire who changed the execution list of the Hunter's Association that resulted in the death of her lover, and that the Pureblood vampire the enemy of the Purebloods and him. Yuki encounters vampire sent by the Senate to execute Zero for supposedly killing Shizuka. He attacks her, but Zero saves her. Other vampires from the Senate circle them ready to attack. Before they can, the Night Class students appear. Kaname orders the Senate's assassins to leave stating that he doesn't want Cross Academy spoiled by foolish acts of vengeance. The vampires leave saying that they will report to the Senate that Kaname is protecting Zero. When Kaname insinuates that Zero was the one who killed Shizuka, Yuki claims that she will not speak to him until he admits Zero is innocent. Later, Zero dreams about Shizuka, and awakens calling Yuki's name. When Yuki comes to comfort him, he nearly kisses her, but stops.
