Cielo

The history of this weapon is a bloody one. Hundreds of individuals have died upon its blades or were crushed in its scales. However, its origins are not so impressive.

The metal pole that is the foundation of this weapon was originally intended to be used as building material. However, the people who had bought it didn't need it and it was taken with some other excess material to be dumped into a furnace to be burned back down and remade for some other purpose.

Once again, the pole didn't make it that far. A blacksmith happened to receive it and he decided to round of the pole's edges, but otherwise leave it as it was. The blacksmith had actually been thinking of making the pole into some kind of weapon when someone arrived with an important message for him. While the blacksmith was out of the room, a thief slipped in, but the blacksmith was coming back and in a panic, the thief grabbed the pole and ran.

The thief took the pole back to his boss. His boss was more than a little angry that his subordinate had put the blacksmith on his guard and all he had brought him was a metal rod for the trouble. So he killed the thief as an example and tossed the pole away into a trash heap.

Later that night, another one of the boss's subordinates came and took the pole. This man was an excellent thief, a vicious murderer, and a powerful fighter. He was searching for ways to improve his skills so that he could rise to the top of the pack. A part of his overall goals had already been accomplished: He had eaten a devil fruit. Not long after he had eaten that devil fruit, he managed to get his hands on a second one, but he could not risk eating the second since it would kill him. However, he had no intention of letting that stop him from taking advantage of another fruit's power. He had heard rumors that it was possible for devil fruit to be merged with non-living objects and so he had been planning for a while to create the ultimate devil fruit weapon. All he needed were the right materials, and this pole was just that.

This man knew from experience that the blacksmith who had worked on the pole, was one of the best in the North Blue. The pole was too perfect of an opportunity for him to let slip away. It would serve as the base for his weapon.

The man worked upon the weapon for several years, first adding small holes into its sides so that he could insert blades into it, and then he spent a much longer time merging it together with the fruit he had. This fruit was the Hebi-Hebi no mi; Model: Green Tree Python. Needless to say, the metal pole was a little confused when it gained a mind and transformed into a snake. In its confusion, it nearly killed the man who had given it devil fruit powers. After a lengthy battle, the man defeated the snake and then proceeded to spend a few months taming it.

The next few years of this man's life were very wild. With his unusual scythe in hand he took over the organization he was a part of and then later slaughtered its members when he had gotten tired of it. He did this multiple times, rising to the top of a group and then killing everyone around him. He even took on a new name. It as a name he had read in a history book. The name of a man who had never been caught. The name was: Jack the Ripper.

At long last the man's reign of terror came to an end. While he was the first mate of a pirate crew, he was defeated by a rookie pirate and his scythe escaped from him. The scythe snake vanished into a sewer and stayed there for a while, living off of rats. The python may have been a predator, but it was not bloodthirsty. It didn't want to kill all of these people, but it had no choice so long as Jack held it.

Weeks passed and the python was just starting to get a little less anxious when it was discovered. A young man, who was little more than a boy, found the scythe snake. On their first meeting the snake fled from him, but it stayed nearby observed the man from a distance. It noticed that he was not like its old master. This boy could be vicious, but he was not a cruel person, even towards the sewer rats.

The young man had been down there living in the sewers for almost a week when the snake came to him. It showed him what it could do, changing from shape to shape, and the man did not seem afraid of it. The snake spent the following night sleeping under the boy's shirt, soaking up the heat of his body. From that point on, the two were inseparable. The man brought better food than the rats and he carried the snake and gave it a name. He called it Cielo. In return the snake protected him. It began to build upon young man's knowledge of fighting, teaching him even more, especially how to wield the snake itself.
