Author's Notes: Hello everyone! Before anyone reads this story, I just want to remind readers that this fanfiction is an Alternate Universe story. Some elements in this story is completely different from what is canon in the official Dragon Ball Story.

This work is a free fanfiction created for fun purposes only. It is entirely fiction and any similarities to real people, places, events, religion, etc. are unintentional. The Dragon Ball series, in which some of this fic's elements are based upon, is not owned by the author. All credits go to their rightful owners.

This fic is based on my original story 「Moonchild」 which is inspired by the Korean folklore of the Gumiho: The Nine-Tailed Fox. The main characters of "Moonchild", Yokori Rakesha Ayanami and Mary Cazarine Sol were based on both Vegeta and Bulma, thus making this the Vegebul fic version of that story.


Prologue

The Moonchildren


The Legend of the Children of the Moon, the Saiyajin, was a very popular myth among people from the West City Capital and Gingertown to keep children from going to the ominous Mount Moon at night. The stories varied as to where the Saiyajin originally came from. Some stories say that they were a tribe of shape-shifting humanoid aliens who came from a distant planet wanting to invade the Earth thousands of years ago, while others say that they were monkey spirits who gained the ability to accumulate and manipulate ki, the life force within living mortals, giving them supernatural powers such as shape-shifting into a human-like form to control their beast side, have the power over the five elements, control the weather, and even cause mass destruction around them. Their powers are especially connected to the cycles of the moon, and they're at their most powerful form during the full moon. This is the reason why they were also referred to as the 'Moon Children', and because they were also gifted with great fighting potentials, they were also called the 'Warriors of the Moon'.

One thing is for sure though, the Saiyajin are malevolent, ruthless, and bloodthirsty beings greatly feared for their dangerous powers and savagery. They say that they eat human hearts and livers, and drink human blood to help satiate the sleeping beast within them. They were also known to steal and feed off the ki of human beings to grow more powerful. Ki is the energy associated with a mortal's life force that emanates throughout their bodies. The Saiyajin feed every full moon night when all the gates of energy within them are opened, allowing their full power to flow through them at its maximum potential. They do this by sucking and absorbing a human's ki through a deep kiss, storing what they have stolen within themselves, and adding it to their already extremely mighty energy. The myths tell that they needed to do this to keep their human forms and prevent themselves from losing control or turning back into their rampaging monstrous form, the Oozaru, a giant demonic monkey capable of destroying entire worlds. It also helps them live and enjoy immortal life. It was worth mentioning that the most powerful Saiyajin had eaten thousands of humans in his lifetime, thus it was also assumed that the most powerful among them has a fearsome ability to destroy the entire world if he wanted to.

Despite being just a myth, the elderly believed that the Saiyajin do exist. Forty-five years ago, a group of men claimed to have encountered a Saiyajin while taking a West City Minister to Gingertown. Only one out of the twenty men survived to tell the tale that night, however, the following morning, his grotesque corpse was found in his room. His eyes were wide open, his lips parted while his skin was wrinkled like that of a raisin. His tall and muscular build had shrunken as if somebody had crumpled him like a tin can. His chest ripped open, his heart and liver were missing. Some group of foolish men suspected that this was done by the Saiyajin, so they went to hunt down this creature that full moon night on Mount Moon. Nobody among them was seen alive the following day. Anyone stupid enough who dared to try hunting for the Saiyajin ended up dead, the same as what happened to the survivor. Since then, the Saiyajin had been a subject of fear among humans who lived in the two nearby cities surrounding Mount Moon. Nobody dared to go up that mountain at night, especially when the full moon is up in the night sky.

But with their ability to shapeshift into a more human-like form, who knows that maybe, the Saiyajin were already among its unsuspecting mortal inhabitants, waiting for the perfect time to feast on the blood and energy of their unfortunate victims...
