Summary
Yuki is determined to ask Kaname about her past because he is her first memory. Meanwhile, her hallucinations of blood continue, making her uneasy. Ichiru applies to the Day Class and the Headmaster accepts him after he gets approval from Zero. The Headmaster hopes that the brothers will be able to come to an understanding of one another someday and is proud of Zero for acting so maturely. Ichiru is charismatic and quickly becomes popular among the students, a stark contrast to his older brother. Yuki goes to meet with Kaname but is spooked by an illusion of blood on her hand. In her fear, she attacks Kaname, and he ultimately comforts her and tells her that he loves her. This disorients her and she is unable to ask him about her past. Zero confronts Kaname about Yuki's hidden memories and Kaname pins him to the wall reminding him that he is only allowed to live because he is useful to Kaname in that he will never betray Yuki. Kaname allows him to drink his blood once again to starve off Zero's fall to Level E status. Hanabusa stops Zero as he is leaving the Night Class and asks him to help discover Kaname's "hidden" side. After a talk with Zero about his courage to face his brother, Yuki resolves to talk to Kaname once more about her past. She gets angry with him for treating her like a child and not telling her what he knows. He asks her if she wouldn't rather stay blissfully ignorant of her past, but she emphatically explains she wishes to be strong and know the truth. He then expresses his concern that the truth will make Yuki hate him, and though she says she could never hate Kaname, he makes her promise to be his lover before he will reveal the past. When he hugs her for comfort, he notices Zero looking at the two with his "worried eyes" since Kaname knows how much Zero loves Yuki.
