Kotori

Biodata

Background

Kotori is Shido Itsuka’s adoptive younger sister. At age thirteen, she attends middle school while secretly commanding Fraxinus, Ratatoskr’s vessel for helping Spirits live peacefully through Shido’s ability to seal their powers 67 111.

On her ninth birthday, Kotori believed her family had forgotten her. A mosaic-covered figure later called Phantom exploited her wish for Shido’s approval and gave her a Spirit Crystal. Her transformation released flames she could not control, setting the surrounding area alight and severely injuring Shido. Following Phantom’s instructions, Kotori kissed him; her power was sealed, and its healing flames restored him. Phantom then erased their memories of the incident 194 195.

Years later, Kotori reclaimed her power to save Shido and Lingmeng from Kurumi. Her fight revealed both the strength of her flames and their danger: after defeating Kurumi, Kotori lost control and tried to kill her until Lingmeng knocked Kotori unconscious 139 140 141 142. Shido subsequently sealed her power again. Kotori said she felt safer without the risk of another loss of control 197.

Appearance

Kotori has long red hair, usually tied into twin tails. She associates her black ribbons with her assertive “Commander” self and her white ribbons with a more timid little-sister manner 175 208.

• Black ribbons — A birthday gift from Shido. When one came loose at a water park, Kotori became tearful and asked him to retrieve it; she regained her usual composure when he returned it 175 195.
• Spirit form — She wears a vivid, kimono-like Astral Dress surrounded by flames 139 188.
• Commander’s attire — She is seen with a crimson military jacket over her shoulders and a Chupa Chups in her mouth 208.

Personality

Kotori is decisive in command but attentive to the people under her care. She sees Ratatoskr’s staff as family and knows even lower-ranking officers by name 180. She also refuses to abandon Origami during a battle with Ellen, despite the risk that intervening will expose Fraxinus 392.

Her confident manner can conceal fear and affection. She dresses up for her date with Shido but blushes when he notices, and she denies having unusually strong feelings for him despite affection readings already being at their maximum 159 197. She takes her responsibility for Shido seriously: when Ratatoskr’s executives fear his ability to wield Angels, she reluctantly promises to stop him herself if he threatens humanity 292.

Abilities & Skills

• Blue flames close Kotori’s wounds, allowing her to recover even after Kurumi shoots her in the head 140 141.
