Higurashi When They Cry Shion Sonozaki 1ST Cosplay Costumes Deluxe Edition(CV-020-C02)

Shion is Mion's identical twin sister, who currently resides in Okinomiya. In spite of their externally different personalities, she and Mion often switch places, and it can be difficult to distinguish between them. It is noted by Rena that, although externally the twins are very different, on the inside, they are really the same. Their first switch took place when they were little. Right before tattooing the symbol of an demon/oni, which is reserved for the older sister, she was mistakenly identified as Shion, the younger sister, which means that she was actually born as Mion Sonozaki, the older sister. Since then, she switched her identity of Mion with Shion, the younger sister. This initial switch is only mentioned in the sound novel and manga, but not the anime. She was sent by the Sonozaki family to a private boarding school, named St Lucia, but escaped and returned to live near her hometown, where she lives with Kasai. In spite of all this, she and Mion maintain a close relationship.
