Kyokou Suiri (虚構推理) is a multi-stream series by Kyo Shirodaira.
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. Now, six years later, whenever yokai wish for their problems to be solved, they make their way to Kotoko for consultation.
Meanwhile, Kuro Sakuragawa, a 22-year-old university student, has just broken up with his girlfriend after he fled alone when the two encountered a kappa. Seeing this as her chance to become closer with him, Kotoko immediately makes her move, hoping to get married to Kuro one day. However, she quickly realizes there is something more to Kuro. With this knowledge, she asks for his help in solving the various issues presented by the supernatural, all the while wishing her newfound partner will eventually reciprocate her feelings.
Dive into a world of yokai, monsters, spectres, spirits, demons, and ghosts.
