Miya Furutsuki

Miya Furutsuki is Mika Furutsuki's younger sister.

Plot
When Miya and Mika were little, they were both huge idol fans to the extent that the stress (and cost!) ultimately led to their parents divorce. Miya developed a strong hatred for idols after this. After Mika's talent management company closed down, Miya decided to try and have her get a real job. The stress from all of this led to Mika jumping off of her balcony and killing herself.

At the funeral, Miya notices Mika's body looks different and believes Maori Niizono has something to do with it and swears her revenge on her as well.

30 years in the future when Maori manages to revive Mika, Miya is among the crowd of Vigilantes that kills Maori and eats her organs. Before Maori's death though, she manages to put a bullet through Miya's head.
