It was a sunny day on the surface a young Frisk was laying in their bed when a young women walked in with a large German shepherd behind her. The German shepherd was light brown with black patches on its body and its eye. The dog jumped on top of Frisk and licked her face waking her up after getting pushed back Frisk's mother turned to her saying.
"come on Frisk you need to wake up for school" Frisk got their striped purple and blue shirt on and some black pants they then turned to the dog stroking its head.
"good girl Nightshade, now let's go to school" Frisk grabbed their backpack and ran to the door, pulling it open Nightshade ran after Frisk and ran alongside her as they ran to the school gates. When Frisk got to the gates she turned to Nightshade petting their head and going into their bag pulling out a large bone which they through to Nightshade who caught the bone and began to chew on it laying down in the sun. A few hours went by and Frisk emerged from the school and went to Nightshade. "hey girl where's mum at?" The response to this was a small whine and a tilt of her head. The duo waited a few hours until Frisk decided to walk back home when they got their Frisk noticed how her mums car wasn't there turning to Nightshade Frisk said. "Nightshade go 'round the back" Nightshade barked and ran into the back garden. Frisk opened the front door and saw her dad in the recliner in front of a static TV.
"It's your fault" The dad didn't move he just sat there.
"Dad what are you talking about?" he lunged out and grabbed Frisk pinning her to the wall.
"your mothers dead! And its because of you!"
"what?!"
"she was on her way to pick your ungrateful ass from school. Now your gonna pay" his grip tightened when Nightshade suddenly lunged biting into his arm and throwing him to the ground. The man held his now bleeding arm and screaming in pain Nightshade went to Frisk and pushed her nose into her side and pushed her up. Frisk got up and ran with Nightshade to a hole in the wire fence Frisk ran though the hole followed by Nightshade. As they run with the wilderness they hear the dad chasing after them when suddenly Frisk tripped and fell into a hole when Nightshade caught her on the collar of her jumper. Frisk hung precariously over the hole and the dad was gaining on them. From behind the dad pointed a gun towards Nightshade and fired the bullet skimmed her leg making her stumble forward and let go of Frisk. They had both fallen into the Underground where all of the monsters lived and boy were they in for an adventure.
