In a certain place, there was a yokai known as Takuroubi. As anything it touched burned, it lived avoiding humans and even yokai. Ratman approaches Takuroubi and proposes that he work for humanity's sake, taking advantage of the deep loneliness that Takuroubi feels. Thus, Ratman's attraction, BiBiBi Fire, becomes a big hit. Takuroubi was ordered to never leave his room at night, but one evening, unable to stand the boredom, he goes out. He meets a mysterious robot, Pig. Takuroubi and Pig hit it off immediately, and their friendship quickly deepens, but...
I didn't know it was you and I hurt you...
...لم أعلم أنّ هذا أنت وآذيتك
Ich habe dich nicht erkannt
