The story of Chaos is simple.
He was originally a little beggar, robbed of all the money he had begged for by a vagabond and beaten to within an inch of his life before being thrown into a rubbish heap to die.
Kyle took him back and saved his life.
From then on, he lived with Kyle.
But Kyle was not a good man; all he needed was a flexible and useful tool.
They hid in an amusement park situated in a remote corner of Kaye City.
There, Kyle began to train Chaos; the training content was not complex, just some basic physical skills, but the methodology was exceptionally brutal,
Little Chaos failed to perform even a little, and he would be beaten severely, then Kyle would pay for his treatment.
Kyle took great pleasure in this abuse, and his methods of punishing Chaos became increasingly extreme.
