Goku Learned a Lesson

"Ah!!!" Goku clutched his head and screamed as a gleaming axe shattered against it. The axe had left a red swollen lump on Goku's head. "Just... just as useless as I thought." A middle-aged man wearing glasses, bald on top with long hair on both sides and a thick handlebar mustache, stood there in blue overalls and a yellow shirt, looking terrified and at a complete loss. Seeing that Goku was unharmed even after being struck by an axe, the middle-aged man trembled where he stood.
