Ren Kiryu

Ren Kiryu is the only son of Yuki Kuran and Zero Kiryu. He is an aristocrat due to his mother being a Pureblood vampire and his father a regular vampire. He appears at the end of Chapter 93 with his older half-sister to give Yuki's final message to Kaname when he wakes up from his 1000 year slumber.

Appearance
Ren is a tall attractive and handsome young man with silver hair, snowy-white skin and lavender eyes as his father Zero. He also bears a close resemblence to his uncle Ichiru.

Personality
While his interactions are limited in the extras he has been shown to have a calm demeanor and will speak up whenever his sister has difficulty expressing herself. He appears to have a good typical sibling relationship with Ai as they both are shown scolding one another. While calm in nature like his father, Zero, Ren does not appear to have Zero's stoicism as he is shown smiling and joking around with Ai. However, while he seems to have inherited his playful side from his mother, Yuki, his blunt nature definitely resembles a teenage Zero as he states whatever Ai has difficulty expressing.

Story
Ren appears at Kaname's resting place along with Ai and his mother Yuki. Ren and his 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 his 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.

His name was revealed in third extra chapter.
