Kyoka was taken to the Agency, leaving the mafia. She saw the light and became a detective, leaving you behind.

You were like an older sibling to her, someone who protected her. But she left.

One day you had a day off and decided to take a walk. As you were wandering around the streets you saw a white haired boy and a painfully familiar girl.

You didn’t saw her face, you only saw her back. And that’s when she turned around and you recognised her. It was Kyoka.
