Kuro's grandfather was called "Black Lightning" by his friends because, long ago, he beat a dragon in a race. One of those friends, an old dog called Grampy, predicts that the dragon will soon return. Hearing this, Kuro decides to take up the challenge!

Takeshi's backpack is filled with snacks. Tama, accompanied by Tora and Pochi, goes chasing after him and his classmates on their class outing. They cross railroad tracks and rivers, facing many dangers... Will Tama and the others ever find the snacks they seek?
I remember exactly how Black 
Lightning ran back then.
.أتذكّر تماما كيف كان يركض البرق الأسود
Wie der Schwarze Blitz
damals gelaufen ist.
a correr como Trueno Negro
porque lo recuerdo perfectamente.
Tu dois apprendre
comment courait l’Éclair noir.
Ricordo perfettamente come correva all'epoca.
Afinal, eu me lembro muito bem
como ele correu naquele dia.
Я точно помню, как тогда
бежал Чёрная молния.
