Yuki & Hanabusa

Yuki Cross (Kuran) and Hanabusa Aido have some moments in the Anime, mostly comical ones. At first, Hanabusa treated Yuki in a disrespectable manner, calling her by saying "Hey You!". As the series continues, Hanabusa begins to refer to Yuki as "Cross Yuki". Later on, when Yuki is revealed to be Kaname's younger sister and a pureblood, Hanabusa begins to respect her more. Part of him does the respecting towards Yuki for Kaname, but the other part was because Yuuki was a pureblood, and a princess too. From the discovery of Yuki's past, Hanabusa began calling her "Yuki-sama" and occasionally adding "Cross Yuki" by mistake, then correcting himself. Hanabusa also noted that "Yuki's personality changed when she became a vampire", proving that he might have had feelings for Yuki's human self.

After the one year time skip, Aidou is seen as her teacher.
