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...?!
If anything happens to me,
you'll be hearing from Kitaro.
.لن يصمت كيتارو إن حدث لي مكروه
Wenn mir was passiert,
wird Kitarō nicht still dasitzen.
Si me sucediera algo, Kitaro 
tomaría cartas en el asunto.
Si me pasara algo,
Kitaro tomaría cartas en el asunto.
Si quoi que ce soit m’arrive,
tu en répondras à Kitarô.
Se mi succedesse qualcosa, 
Kitarō reagirebbe sicuramente!
Se alguma coisa acontecer comigo,
você vai se ver com o Kitaro.
Если со мной что-то случится, 
ты познакомишься с ним поближе.
