(Vampire Knight) Zero's Mysterious Little Sister

Kira Kiryu is Zero's little sister and she spends most of her time with Zero no matter what for she fears of losing him just like they lost Ichiru. Kira also has a sad past and she needs Zero to comfort her although she's mostly misunderstood from her odd behavior of being to close to Zero, she tries to as social as possible. Kira tries so hard to help Zero with his "situation". Kira is also a half vampire like Zero (not a level E). She is also on the disciplinary committee (Idk how to say that word, my god) so she can protect Yuki and Zero from harm from any of the vampires. But after being adopted by Kaien Cross, him and Yuki were the only ones who found Kira kinda.... strange except for Zero. He loved her and would never let anything happen to her. But will he still love her even if he and the others including the aristocrat vampires and Lord Kaname himself found out about her biggest secret. READ MORE TO FIND OUT OUT
