Kotoko Iwanaga

Kotoko is the main female protagonist in Kyokou Suiri and the current girlfriend of Kuro Sakuragawa. 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. At the young age of 11, Kotoko Iwanaga was abducted by yokai for two weeks and asked to become their "God of Wisdom," a mediator between the spirit and human worlds, to which the girl quickly agreed but at the cost of her right eye and left leg. After what happened, whenever yokai wish for their problems to be solved, they make their way to Kotoko for consultation. She was discovered with "her left leg amputated and her right eye carved out." (Source: Kyokou Suiri Wiki)
