Blood Ties

What happens if Yuki in the anime Vampire Knight had a younger sister who she had never met?🤔

If her younger sister named Riku was turned into a human at birth, kept hidden from the world because her power was beyond control and if found out Rikus parents would have to give up there second daughter making the daughter be a slave to the vampire association?

So Riku parents turned her into a human and gave her off to the only man they could trust, his name the one and only Kain Cross.😏

However when family problems broke out for more pure blood power, the mom turned Yuki into a human telling Konami to keep watch of Yuki and never let anything bad happen to her. But just as she was going to tell Konami of Yuki having a sister, it was to late the mom lost conshness after turning Yuki human.

Making Konami put a certain pure blood to slumber temperarlly?

What would happen after Yuki finds herself alone in winters snow, comes a cross a bad vampire having Konami save her and sending her off to Kain Cross the man his mother told him stories about.

Would he get a chance to meet the younger sister? Or Yuki meets her first 'Riku' and when Konami comes for a visit meets up with Yuki and her friend/sister Riku whom they are still clueless of there blood relation.

Will they discover this secret? And would Riku be able to face the challenges ahead?

How will Riku be able to face the fact that she has a sister and a brother she was kept from all these years, not only that but she is a pureblood as well??😋😓😲
