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...
When I was with you,
I felt I wasn't alone anymore!
شعرت أنّي لم أعد وحيدًا
!عندما كنت معك
Ich dachte, da du bei mir bist,
brauche ich nicht mehr allein sein.
Al estar contigo ya no me sentía solo.
Contigo ya no me sentía solo.
Quand j’étais avec toi,
je ne me sentais plus seul !
Quando ero con te, 
riuscivo a pensare di non essere più tutto solo...
Quando eu estava com você,
eu não me sentia mais sozinho.
Когда я с тобой, мне больше не одиноко!
