Yuna Miura, was one of the few Japanese pure-blood descendant who migrated in London together with her Wizard parents since they were assigned to work in Ministry of Magic. She attended Hogwarts on where she met Samuel Cavanaugh, another pure blooded wizard that lived throughout his family's tradition. The Cavanaughs are known by thoroughly maintaining their status as a pure wizards. Therefore, most of the marriage that happened within the family are arranged by their kinds. Fortunately, both Yuna, and Samuel was pure-blood and there were no argument about their relationship during their time. They married and lived like a normal family in London.

Shion, their youngest was the most free spirited son that they've given birth to. Unlike his two older brother, he does not really want to live by their family's tradition. He always felt that what they were doing was manipulating their individual life. However, it is only their tradition that he's in disfavour of.

People always say that he doesn't look like his two brothers, and her mother's Japanese genes are flowing in him. Though his feature resembles his father's, the vibes from him is like his mother's.

Shion is very ambitious and determined to have the things that he wants. He was aware of their kind and together with his brothers, they have been cultivated about the Wizard world.

The first time that he felt being one them was when he went to camping with his brothers. He was 7 years old and was not aware at that time that he's unconsciously making the apples fall off the ground without touching it. He felt the excitement and thought that it was only his lucky day, but his two older brothers already noticed the changes that is happening to Shion.

He was looking forward mostly in learning in Hogwarts, but his main goal was to be successful more than anyone else.
