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?
though he was called Fleet-footed 
Kuro-chan back then.
.مع أنّ كورو-تشان كان يلقّب بالسريع حينها
Aber zu der Zeit wurde er
noch schneller Kuro genannt.
Aunque fui yo quien lo llamó
Kuro el Velocista.
en même temps que l’Éclair noir,
qu’on appelait Kuro la Flèche.
Però all'epoca lui era ancora conosciuto
come Kuro lo svelto.
afinal, nessa época ele era
chamado de Kuro-chan, o Ligeiro.
хотя тогда его звали
Быстроногий Куро.
