Introduction

They became known as the troubled three. Aki, Tatsuya, and Mirai had the same parents but their mother's origin was unknown to them. Their father was definitely a first blood but their mother could be a human, first blood, vampire, or any of the other races in the demon world. Their mother could have been an experiment as well created to give birth to children or just be a test subject to lead her family to prosperity.

Aki () was the eldest of the three and heir to their family. She was betrothed to her unborn brother and predicted to bring new life to all the races in the demon world. She spent most of her life in the human world traveling after her mother used a forbidden spell to be bound to her father.

Tatsuya (達也) was the middle child of the three. He was locked away in a tower and was not allowed to have contact with anyone. He had contact with the aides to his mother's family Mei and Masato.

Mirai (未来) is the youngest of the three. The human family that adopted her mother raised her, but her mother had entrusted him with her youngest child. Karl had other plans for Mirai though but was not sure how she would fit into his bigger plot.

How will these three fit into the new world they are living in? What role will Aki and Tatsuya play and will they put a thorn into Karlheinz' plans? How will Mirai adjust to her role in everything? How will Aki, Tatsuya, and Mirai react to Yui and the situation she is in? Will Karl end up using the troubled three for his own twisted plan?
