On a distant beautiful planet, everything was perfect! All the inhabitants of this planet lived in friendship and built a healthy society. They developed science, medicine! But where there is good, there will always be evil.. And this planet had its faults. Genetics was very well developed, so doctors could remove all the negative and evil neurons from a child's head before birth. But nature cannot be defeated, so these neurons were added to the head of every hundredth child to restore the balance of nature. These children were called "The Hundredth". They were sent to a separate colony on a satellite of this planet, and there was a settlement of the Hundredths. They had their own society, there was anarchy and no order. Among this mess was one unique person, a beautiful girl who worked as a bounty hunter. She worked as a bounty hunter, hunting down and eliminating particularly violent Hundreds. It was what she did for a living, and she was very good at it!
