As the city prepares for Halloween, Ratman walks down an alley and a strange shadow appears before him. A voice declaring itself the true son of the emperor of the European Youkai, Backbeard, Backbeard Junior, belongs to the European youkai Bat-cat. Bat-cat asks Ratman to help him collect blood for the ressurection of Backbeard. He has a reason for wanting to achieve something great. Ratman turns him down, but when the huge reward is set in front of him, he changes his mind and offers to help. But there's no way Ratman will simply do as he's told and collect blood, is there...?!
I'm going to take my place as
King of the Yokai!
!سآخذ مكاني كملك لليوكاي
Ich werde als König der Yōkai herrschen!
¡Yo seré el rey de los yokai!
¡Yo seré el rey de los yokai!
La place de roi des esprits
me revient de droit !
Regnerò come re degli yōkai!
Eu vou assumir o meu
lugar como Rei dos Yokais!
Я займу место короля ёкаев!
