The Azure Portrait (永遠の約束, Ruridama no Miraju) is the sixteenth episode of the Vampire Knight Series.
The Night Class students except for Hanabusa Aido and Senri Shiki, who is going to see his mother instead, go to the Aido family residence for the holiday. It is revealed that Hanabusa asked Akatsuki to investigate Kuran-dojo's secret. Meanwhile, he is still troubled over the fact that Kaname killed Shizuka Hio and runs for comfort over to the Day Dorms, where Yuki and Zero are. It is over there where he reminisces about his childhood and encounter with Kaname.
The students of the Cross Academy leave for the holiday, and Rima, Ruka, Kaname, Akatsuki, and Takuma go to the Aido family residence; however, Hanabusa stays on campus. Shiki goes to his home rather than the Aido residence, as he was summoned by his great uncle. In the Night Class dorm, Hanabusa recalls asking Akatsuki to investigate Kaname's family while at the Aido residence. Hanabusa goes to the Day Class dorm, and meets Yuki and Zero, who makes dinner for him. Afterwards, Hanabusa takes a bath and recalls meeting Kaname when he was younger, noting the change in his personality before and after Kaname's parents died. While making dinner, Yuki cuts herself and tells Zero to drink the blood, a scene witnessed by Hanabusa. He returns to the Night Class dorm and enters Kaname's study, where he realizes Kaname is planning something.
