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...!?
The country and all those
big scientists couldn't do anything.
الدولة وكل أولئك العلماء الكبار
.لم يستطيعوا فعل شيء
Das Land und all die
schlauen Köpfe waren machtlos.
Los políticos y científicos 
no pudieron hacer nada.
Los políticos y científicos
no pudieron hacer nada.
L’État et ses scientifiques
n’ont rien pu faire.
Né il Paese né eminenti studiosi hanno potuto nulla...
O país e aquele monte de
cientistas não pode fazer nada.
Ни страна, ни учёные
ничего не могут сделать.
