Shion Zwei Shinomiya (紫音・ツヴァイ・篠宮), formerly known as Kraken Zwei, is a former antagonist and one of the supporting female characters in the Unlimited Fafnir series. She is a Dragon/D hybrid born between the 'Purple' Kraken and the dragonified Miyako Shinomiya. Although she was closer to being a Dragon than a human, upon being selected by Yuu Mononobe as a mate, she lost most of her Dragon characteristics, reverting into a more human-like appearance and personality. Shion eventually enrolled in Midgard and became part of Brynhildr Class.
