Saiko Yonebayashi is a key member of the CCG's Quinx Squad, whose path to becoming an investigator was anything but voluntary — it was orchestrated by her mother in pursuit of financial compensation. Known for her love of video games and her reluctance to leave her room, she embodied the image of a disengaged, stay-at-home investigator. Despite possessing remarkable Kagune abilities, she showed little drive to put them to use. Everything changed when the loss of a dear comrade shattered her passive world, awakening a fierce resolve within her. Rising to the challenge, she now wields her formidable power as a true guardian of her squad.
