Despite her being seemingly more girly and refined than Mion, she is incredibly shrewd, manipulative, and delinquent. Like Mion, Shion often behaves as a very cheerful and friendly girl. Shion tends to become envious very easily and frequently, which contributes to her progression of the Hinamizawa Syndrome, her violent insanity, and how she chooses to seduce the victims "to make sure they get what they deserve." Shion is voiced by Yukino Satsuki in the sub and Megan Hollingshead in the dub.
