87th Night

Masquerade is the eighty seventh chapter in the Vampire Knight manga.

Summary
Yuki and Zero leave the mansion, with Yuki saying it's okay if they hurry, since it has good and bad memories within it. They board the underground train to see Isaya, an old friend of Yuki's parents, to ask for help. While on the train, Yuki sees that Zero has satisfied his bloodlust for over a year. Zero reveals that he has drunken the blood of madness from Level E vampires. Yuki knows what it's like to have bloodlust and that abstaining from it is difficult. Although Zero wasn't satisfied by the Level E vampires, he says, "Therefore,"  with Yuki following with, "In that case..." He then stops and looks at Yuki with a lighthearted expression. Then, Zero sits down and says his bloodlust being insatiable is none of her business. Yuki realizes that more words should have been said then and that they act as if they conceal their hearts behind a mask. They get off the train, and Isaya's servant gives them an invitation to a masquerade.

Yuki dresses in an extravagant gown and sees that the guests seem uneasy, waiting for Kaname to show up. Isaya says he couldn't remain a spectator while the children of his beloved old friends were at the heart of the problem. He then dances with Yuki, while Rima arrives with three other mysterious figures in cloaks. Yuki jokes around with Zero, pretending, while wearing a mask, that she's meeting him for the first time. They then dance together and Yuki is surprised that he can dance. Zero says that Yuki is very similar to a girl that died a year ago and Yuki agrees he's similar to the boy who she wanted to protect, yet she hurt him. Zero isn't the same person now since he isn't someone who'd dance with a vampire. Flashbacks of Yuki and Zero as children are shown with Yuki caring for Zero, him leading her out of the dark forest, and them in the Night Class, back when Yuki seemed really happy. Yuki wonders why they had to end up being enemies, that Zero become someone she wants to cherish, and that the feeling inside her is real. Yuki then notices Kaname has arrived at the masquerade as she takes off her mask.
