Saiki K's Lost Sister

Emiko (Evangeline) Miyaki. She always thought that well, her parents were, well, her parents. Even if they didn't look alike. She loved her parents. She really did, growing up in the US, even though she was left alone with her big sister almost all of the time. They were still her parents. They were all family. Emiko..... she's a witch. And she had to hide it from everyone. And then..... the family she almost never had just... died. A car crash. But Emiko, as a witch, survived. And the police couldn't find any family. Until they did a DNA test. Turns out..... her real family's in Japan. And she even has a twin brother. Saiki K. And then she transfers in to PK Academy, and everything seems "normal". But a secret organization is after the powers. They think that people like Emiko, Saiki, and Toritsuka shouldn't be alive. Turns out.... There's more all across the world. From as close to South Korea to Fiji. There's a ton. And the organization is desperate to capture those..... enhanced beings and experiment on them.
