Kaname Kuran

Kaname Kuran (玖蘭 枢 Kuran Kaname) is a Pureblood vampire who saved Yuki from an attack by a Level E when she was a child. Kaname is revealed to be one of the original vampires and founder of the Kuran family. He was raised as Haruka and Juri's son after being reawakened by Rido Kuran, who used the Kuran's first child as a sacrifice, making him Yuki's brother and ancestor. He worked together with Kaien Cross to establish the Night Class to promote peaceful co-existence between vampires and humans. During the first arc, Kaname spends his time working to protect Yuki, which includes killing Shizuka Hio and fostering Zero Kiryu's powers. During Rido's assault on the school, Kaname destroyed the Senate. Following the time skip, Kaname begins a plan to eliminate all Purebloods aside from Yuki, even willing to place his own heart in the furnace that produces the anti-vampire weapons. The night before he sacrifices his heart to the furnace, Kaname sleeps with Yuki. His body is preserved in ice by Hanabusa. Kaname's notes on transforming vampires into humans without sacrificing a Pureblood are found by Hanabusa, who perfects it. After centuries pass and the furnace is to be shut down, Kaname is resurrected by Yuki as a human; their biological daughter Ai Kuran, along with Yuki and Zero's son Ren, passes on a message from Yuki saying that the world he sees as a human is just as how she saw it.

Kaname's name means Hinge or Door (Kaname) and Nine Orchids (Kuran).
