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...
I'm the one who killed Machii, and I'm 
the one who embezzled the money!
!أنا من قتل ماتشي وأنا من اختلس الأموال
Ich war es, der Machii umgebracht hat. Und ich
war es auch, der das Geld unterschlagen hatte.
Yo soy quien mató a Machii
y desfalcaba el dinero.
Yo soy quien mató a Machii
y desfalcaba el dinero.
J’ai tué Machii.
C’est moi qui ai fraudé.
Sono stato io a uccidere Machii...
Eu que matei Machii e
me apropriei do dinheiro!
Это я убил Матии…
Не он, а я присваивал деньги…
