Crystal Heart

Yuki Hajime is a runaway yokia princess but she doesn't even know it. Her maid made sure that at least one heir survived and that she should never remember who she is or where she came from. She was found by a small family that weren't human nor related but were family nonetheless. 20 years later, they must go to Tokyo to investigate what is causing disturbances to the people. The master has offered Yuki to go to the human school. She agrees. She makes sure to not get close to any human there and to only get info out of them. But when she meets a boy named Haruka Takao, everything changes. Can a yokia and a human be together, can Haruka also be able to unlock her memories. But nothing comes free. Is Yuki ready to lose everything just to find herself and love?
