Background / History
Miko was an ordinary high school girl until her Spirit Vision awakened. Returning home one night, she saw a distorted Evil Spirit in her bathroom mirror. Terrified, she concealed her reaction and pretended she had seen nothing; this becomes her initial survival strategy as further spirits appear at school and around the city. 436
Her awareness isolates her from Hana, who cannot perceive the phenomena tormenting her. Seeking protection, Miko considers visiting shrines and even becoming a Miko, though she initially treats the idea as a desperate possibility rather than a life plan. 438 445
Gu Mo investigates the circumstances of her awakening and later offers her a position at his Shrine. Although hesitant because of school and her desire for a normal life, Miko accepts his contract after fighting alongside the Countermeasures Office's exorcists during an A-Class Evil Spirit incident. 440 447 459 465
Miko's perception subsequently becomes central to the world's instability. Her cognition unconsciously influences reality, and her observations allow her to perceive rewritten history and the broader consequences of the changing world line. 472 484 487
Appearance
Miko is a black-haired, long-haired high school girl whose ordinary appearance contrasts sharply with the supernatural world only she can see. She is repeatedly described as notably beautiful, attracting attention from classmates and passersby. 436 472
- Long black hair. 436
- Usually wears a school uniform while attending classes with Hana. 436 465
- Wears pajamas at home. 436
- Her outward composure often conceals trembling, tears, and intense fear. 436
Personality
Miko is frightened by Evil Spirits but extraordinarily determined not to reveal that fear. When her Spirit Vision first appears, she repeatedly forces herself to act normally even when she believes she may die. 436 440
She is cautious and easily overwhelmed by supernatural developments, yet her instinct is protective rather than passive. She pulls a distracted young man away from traffic, worries deeply about Kyosuke, and shields him when confronted with dangerous supernatural figures. 438 449 463
Despite lacking knowledge of her own powers, Miko can project seriousness and confidence under pressure. This leads Yomi to initially mistake her for a far more experienced exorcist than she truly is. 461

Observer Effect
Miko's cognition and observation possess an unconscious influence on reality.
- The world appears to adjust details and probabilities in response to her thoughts and cognition. 472
