Kotoko receives a request for help from a giant snake, who is the guardian spirit of Tsukuna Swamp. It appears that a murderer named Tanio Aoi disposed of a body in the snake’s swamp, but there’s something that’s just not sitting right with the snake. After learning about Kuro’s powers, Kotoko asks Kuro to accompany her on this journey, but Kuro declines for a certain reason...
Because he had been stabbed in 
the chest with a sharp knife,
اعتبروا موته جريمة قتل لأنّه طُعن
Da er Stichwunden
im Brustkorb hatte,
Como fue apuñalado en el pecho
con un cuchillo,
Como fue apuñalado en el pecho
con un cuchillo,
À cause des marques de couteau
sur le torse, on a conclu au meurtre.
Sul petto aveva una ferita
causata da un coltello acuminato,
Como ele foi perfurado no peito
com uma faca afiada,
На его груди был след от удара ножом.
