The main female character in the Gemini of the Meteor storyline is a young woman from Vladivostok, Russia. She has an Eurasian background with a Japanese mother and Russian father. Suou shares her life with her twin brother Shion, who uses a wheelchair. During this narrative arc, she becomes entangled in the complex web of conflicts between various factions and Contractors. Her encounter with Hei leads to significant changes in her life. It is later discovered that she possesses some form of contractor ability which manifests when she experiences mental shock. Though not explicitly stated, it's implied that Suou can create a PTRD-41 rifle from a meteor fragment she wears. She handles the weapon with ease and skill, though whether this is also part of her Contractor power or not remains uncertain. As compensation for her services, Suou is tasked with folding paper into origami birds.
