Kotori Itsuka may appear to be an ordinary middle school girl, but beneath that façade lies the commanding mind behind Ratatoskr—a clandestine organization dedicated to resolving Spacequake crises through peaceful means. As the Spirit codenamed Efreet, she wields formidable power of her own. Her most iconic trait is her ribbon: a white one reveals her sweet, clingy side around her brother Shido, while switching to black transforms her into a sharp, no-nonsense commander who orchestrates Shido's dates with Spirits to seal away their powers. She is a pivotal force driving the narrative forward.
