Personality
Rarely speaks
Deeply distrustful of humans
Ruthless in combat
Tender-hearted toward animals
Emotionally unexpressive
The youngest of the Origami sisters, Koori first appears as a subordinate of Morgana, placing her in direct opposition to the protagonist's allies. Reserved to the point of near-silence and harboring a profound mistrust of humanity, she reserves her rare warmth exclusively for animals. Despite her childlike appearance and almost imperceptible emotional range, she demonstrates exceptional marksmanship in battle and shows no mercy toward her opponents. Beneath her cold exterior lies a deep, unspoken devotion to her two elder sisters.
