When Mana visits GeGeGe Forest, she finds Kitaro and Ratman arguing over something trivial. They each declare for the I-don't-know-how-many-th time that they're cutting ties with each other. Meanwhile, in town, the water has been contaminated sending everyone running around looking for drinking water. No one knows why the water is polluted, and no attempts at purifying it work. Kitaro believes that the one behind the pollution incident is one of the Four Generals of Betrayal. Kitaro begins an investigation, but doesn't know how to stop the pollution of the water. Meanwhile, a survivor of the Way of the Demon Society, Isurugi Rei, begins to move again...!?
Is it pity? For a half-yokai like him?
هل من دافع الشفقة؟ على نصف يوكاي مثله؟
Doch nicht etwa aus Mitleid,
weil er ein Halb-Yōkai ist?
¿Acaso te compadeces 
porque es medio yokai?
¿Acaso te compadeces
porque es medio yokai?
Tu as pitié du bâtard qu’il est ?
Non proverai mica compassione 
per quel mezzo yōkai?!
É pena? Por um meio-yokai como ele?
Неужто из жалости? 
Ты жалеешь полу-ёкая?
