prologue A young girl with long blonde hair with blue eyes and a whisker marks and is wearing a white sundress around the age of six is seen climbing up the mountain, if you are to zoom in you'll see that she is crying. The girl's name is Naru Uzumaki the reason why she is crying is because her whole village hates her she doesn't know why but it has come to the point that she couldn't take it anymore and decided to climb the forbidden mountain called MT. Ebott. Why is the mountain forbidden you ask? Well it is said that if you climb MT. Ebott you'll never be seen again and that's what Naru wants.

she looks down sdaly as she continued she trips over a vine and trips and falls inside as blood splatters on the golden flowers around her. A red heart appears as it turns upside down into a monster soul as Naru opens her eyes and sees that she her dead body as she gasped and looks at her hands and sees no flesh but bone she looks around and sees a puddle as she looks in it and sees a skeleton looking back at her as she gasped as she started to cry as surprisingly tears came out of her sockets as a shadow looms over her as she turns around and gasps. Standing over her is a tall skeleton wearing a white lab coat and glasses and a grey turtle neck and black pants and black dress shoes the skeleton frowned as he knelts down.

"Its okay little one I'm not going to hurt you,now where are your parents are you lost?" He asked as Naru cried. "My parents are dead they died when I was born." she tells him as the skeleton frowned but then smiles softly. "Well then little one would ou like to come home with me, I can become your father and plus I have two sons they can both become your brothers?" He asked as Naru's eyes lit up as she hugs the tall skeleton.

"thank you daddy." She says as the tall skeleton smiled and hugs her back. "You're welcome my daughter, oh and by the way what's your name?" He asked her as the young female skeleton smiles. "My name is Naru,what's your name daddy?" she asked as the tall skeleton laughed. "My name is WD Gaster." he says as he wraps Naru up in his lab coat as he made a note to himself to buy Naru some clothes later as he picks her up and begins to walk out of the ruins with his new daughter.
