NARRATOR PESPECTIVE
"Bye mom. Bye dad." shouted a 13 year old(1) girl leaving for school. After a couple minutes of walking she made it to school and met up with two other kids and said "Hi Tucker. hi Sam." getting "Morning Dani." from Tucker. And a polite "Hello and good morning Dani." from Sam. When the three made it to class they were a couple minutes early so Dani told Sam and Tucker about a ghost portal her parents have been working on and how it should be finished by the time she got home and she asked them if they wanted to come over and see it. Sam said she would but Tucker said his parents wanted him home for something.
Fenton Works (after school)
Dani takes Sam down to her basement. Once they got there Dani told Sam to put a hazmat suit on cause her parents inventions don't usually end well and that's why Dani's older sister Jazz was kneeling behind a makeshift bomb-shelter made from flipped over tables. After they put their hazmat suits on Dani dragged Sam behind Jazz's barrier. Waiting for her parents invention to blow up not telling her parents that though. To her surprise nothing happened when they tried to turn it on it didn't even flash. Depressed, her parents went upstairs.
Dani tells Sam she's gonna look inside it to see what was wrong. Before Sam or Jazz could respond Dani got up and started walking into the portal when she tripped and her hand landed on a button she checks and realizes it's the on button when suddenly she's surrounded by a green light screaming in pain Sam and Jazz were the only ones to hear though since the basement's sound proofed.
"Dani!" Sam and jazz came running towards her to find she now had long snow her head white hair with cat or dog-like ears on and a sword on her back. First thing they do feel her ears.
Somewhere in Amity
A woman that had red eyes, Japanese fans, and was in a kimono "Hmm seems there's a hanyo with youki similar to Inuyasha's." "Inuyasha was someone you knew before you came here, correct Kagura?" asked a man that was with her. "Yes, Ryuuta"(2) she responded "But there's something strange it just appeared yet it seems to be a teenager and there seems to be another energy mixed in."
Back With Dani
"Ah my head." complained Dani as she sat up "what happened?" "lets see you went to examine the portal, tripped, landed on the on button, your hair turned white, a sword on your back and you have animal ears on your head.""Anything else?""Oh and now your eyes are green and glowing." responded Sam Dani blinked a couple times and said "what?"
