Ren Kiryu or Ren Kuran is the only daughter of Yuki Kuran and Zero Kiryu. Due to her mother being a Pureblood vampire and her father being an ex-human vampire, she is a Aristocrat. Ren appears at the end of Chapter 93 with her older half-sister to give Yuki's final message to Kaname when he wakes up from his 1000 year slumber. Along with her mother's cousin Senri, she is one of the only known vampires from the Kuran lineage to not be a Pureblood.


Ren appears to be physically a teenager. She has silver hair like her father Zero, however her eye color is reddish brown like the rest of the Kurans. Due to taking after her father Zero in looks, Ren has a rather gender neutral appearance. Due to this and her preference for masculine, more practical clothing, Ren can easily be mistaken for a male.

As a child, Ren had long hair and was dressed in cute dresses by Ai. During her days in the Night Class, Ren greatly resembled her mother Yuki minus her silver hair color.


Ren has a calm demeanor and will speak up whenever her sister has difficulty expressing herself. While calm in nature like her father, Zero, Ren does not appear to have Zero's stoicism as she is shown smiling and joking around with Ai. However, while she seems to have inherited her playful side from her mother, Yuki, her blunt nature definitely resembles a teenage Zero as she states whatever Ai has difficulty expressing. Ren also inherited the kindness of both her parents, never wishing harm on others

Unlike Ai, Ren knows what a job is, even explaining what one generally is; the topic came up when Kaname considered getting one, until Ren informed him that the Kuran family has wealth and resources. Ren knows about this due to attending Day Class in her childhood.

Thanks to Ai doting on her as a kid, Ren is very close to her older sister. Though she slowly gravitated to Zero's company as she showed more interest in learning how to use a gun over being ladylike. When she got her fangs, Ren stayed away from Ai because she craved her blood (ironically enough) and the very thought of draining her dry scared her.


Ren appears at Kaname's resting place along with Ai and their mother Yuki. She and her sister watch their mother give her life to Kaname to turn him into a human. Ren finished Ai's phrase that she passed as a message from their mother to her father "I want to give to you, whom I love, the world that I saw when I was a human".

Ren was born after the events in the extra chapter Life.

In the extra I Like You, Ren and her sister Ai in the end told Kaname the story of the last thousand years, but Kaname had lost much of his memory that he wasn't responding to anything they were saying. As he laid down on the ground, Ai began saying that she did not want Kaname to live the rest of his life not remembering his past. At this point, Kaname embraces them both and asked them to tell the story of the past millennium once again.

Her name was revealed in third extra chapter, however her gender, which had remained ambiguous, was not revealed until chapter eighteen of Vampire Knight Memories.

In the fourth extra chapter, Between The End Of Life And Heaven, Ai had told Ren that they weren't supposed to tell Kaname that Yuki "exists inside of him," but Ren did not regret mentioning any of it for she wanted to see Kaname's reaction. Ren then says that even though there was no point in shaking him up, they couldn't help but bait him despite the fact that Kaname has no memories. Ai then proceeds to wrap her arms around Ren's arm and tells her that they don't know what Kaname is thinking or feeling, that Ren wants to understand that by just observing him. Ai mentions that she has heard things about Kaname from Yuki and Zero but she still cannot believe them, to which Ren responds with a "there must be things you don't want to believe." Ai takes note of Kaname listening to them closely when they speak, that once in awhile he'll ask a question and when they answer him, Kaname becomes silent and listens to them again, to which Ren agrees. Ren then says that they are glad that Ai was not disappointed when meeting her father because they were thinking that he might have a disagreeable nature. Ai tells Ren that they themselves have been thinking that Ren might dislike Kaname to which Ren replies with a serious face saying "I'm still not sure.." That all she thought was that Kaname's hand was very gentle. They both then realize that they've been reflecting too much and Ren asks if they should go back and talk to Kaname again. Ai agrees and says she doesn't want to leave him alone either because from what she's heard, Kaname gets lonely very easily.


  • Ren's name has a similar meaning to her sister, Ai. While Ai's name represents unconditional love, Ren's name is written with the Kanji which is associated with romantic love or crush (恋, koi).
  • Despite being referred to as 'he' in Volume One of the English translation and 'she' in the French translation, it was not until Chapter Eighteen that Ren's gender was revealed to be female. When Ai introduces Ren to Kaname in the third extra chapter, she refers to Ren as her キョウダイ (kyoudai), which means sibling and is non-gender specific. Despite being female however, it has been noted that Ren typically uses a masculine speech pattern in Japanese.[2]
  • Aoi Yūki voices Ren in the Drama CD which came with volume 4 of Vampire Knight Memories.



  1. Vampire Knight: Memories, chapter 18, pages 23 and 24: Ai refers to Ren as "younger sister" (妹, imouto) and "my younger sister" (私の妹, watashi no imouto).
