Smooth translation to English:

A certain true-to-life story

Hey! My comrades, prick up your ears! Hey!
The Lawgiver will tell of what he knows.

Once there was a vicious/nasty boy, and a beautiful woman.
The boy watched the woman while she was singing. She sang, and danced playfully, and it pleased the boy in his heart.

But then-- O my god!! --he murdered the woman! With a sudden motion, he ripped at her skin, he flayed her, laid her open and ate her innards, and just threw the corpse away in the wastelands.

Well now, whatever did we do, eh? We are not to know what I did then. Therefore I keep hidden what I know, and not answer your questions.
