Yui's adopted sister

This is a vampire knight and diabolik lovers crossover.

You where abused at a young age ever since your parents saw your eyes. One was red and one was blue, it was a sin in the Kuran blood line to have those eyes because of one person named Rido Kuran who has the same eyes. At a young age I ran away from because I couldn't stand that nobody liked me. While I was running away I ran into my best friend and adopted sister father Mr.Komori. He may have a vampire hunter but he took me in even though I was a pure blood. Every one at the church knew I was a pure blood but they didn't just ignore me they talk to me but when they approach me they do it with great caution. One day as I was living with father he told me and Yuki we where going to live in the Sakamaki household so he can go on a trip out the country I had no worries and I would have went anyway so I can take care of Yui. The second we went near the Sakamaki mansion I knew they where pure blood vampires. I mean I was fine with it but the only thing I have to watch for is Yui getting told I was a pure blood vampire.
