Introduction by Akira Toriyama

It seems that the second of the complete works is a “story edition”. For me, having drawn the manga by the seat of my pants, to have it called a “story” is only embarrassing. Even so, I suppose that my job of thinking up the story was a little more fun than when I was drawing the pictures. Ah, but to speak frankly, the second half of the story was difficult because I somewhat overdid thinking it up. Though I did a good job continuing it like that… I think.
