Kotoko Iwanaga

Kotoko Iwanaga 永 là nhân vật nữ chính của Kyokou Suiri

Kotoko is a young woman with a petite build and doll-like appearance, often mistaken as a young child instead. She has fair skin and purple eyes framed by short, curly blond hair. As a Goddess of Wisdom, she also has only one eye and one leg, with her right eye and left leg being prosthetics. Her glass eye looks identical to her functioning eye, and her prosthetic leg attaches around mid-thigh height.

Her everyday outfit consists of a white hat with a black ribbon, a white dress with dark blue accents, white socks, brown shoes, and a red cane. The top part of her dress has puffy sleeves and can be taken off independently from the rest of her dress.

After the first arc, she alternates between different dresses.

She has a very outgoing personality and always makes an effort to find the root of any problem, especially when she has the help of yokai. She is oblivious to danger and she tends to be very clingy when it comes to Kuro.

Kotoko is a self-centered, unrepentant prankster, who enjoys poking fun at others expense, and is also a bit of a pervert. She is also shown to have a rather childish demeanor whenever she feels she is not given enough attention or proper treatment, which is aimed especially at Kuro, to whom she can be very pushy.

Contrasting with her mischief belies a cunning individual, well worth her epithet of "Goddess of Wisdom", demonstrating a calculating intelligence that borders in almost diabolical precision and frightening acute. Although she is a terrible liar to her peers, she is a highly manipulative, convincing liar while at work, being able to fool both ancient yokai and a multitude of online fanatics with terrifying accuracy.
