Not What They Seem {Undersoul X Reader}

A Bad Vision, and The Mountain King.

The elevator took you and Frisk to a path weaving thorough a very monochrome city.

"Where.. are we?" You ask Frisk.

"Welcome, to the Capital, just a little ways forward we'll be in new home," Frisk explained.

"Oh, well lets head forward then, " You say pressing on.

As the two of you walked forward, you couldnt help but hear whispering. You stopped and two froggits hopped up, not causing an encounter though.

"Once long ago, a human fell underground," Froggit 1 says.

"Hurt, they cried out for help." Froggit 2 finishes, they both hopped away.

Frisk continued forward, and you followed. You eventually entered a monchrome replica of Toriel's home in the ruins. Being filled with nastalgia you start to tear up. Your memories were interupted when Frisk tugged your arm, and you saw that two Whinsums had flew up to you.

"Asriel, the prince of monsters heard their cry," One squeaked and flew away.

"He took them to the castle, and the king and queen took the child in," follows the other.

Frisk led you forward to be met with Snowdrake.

"The two children became inseperable" The Snowdrake said, "But the child came up with a plan"

The Snowdrake fled, and You continued forward running into a Knight Knight and a Madjack.

"The child told Asriel this plan, she wanted him to absorb their soul after they ate buttercups killing themselves" The Madjack said.

"Asriel listened and brought her body to the village she was from" Knight Knight hummed, "The humans thought Asriel had killed the human so they attacked"

The two monster fled into the shadows. Leading you forward, frisk ran into a Whimsalot.

"Asriel did not fight back, he fled back to the throne room, wounded he fell and died next to the child" Whimsolot said, "Devastated King Asglore declared war on all humans that would fall down here"

Whimsalot fled, and you found yourself infront of another elevator.

"Here we go," Frisk says.

You and Frisk entered the elevator, and you felt it drop you further. When the doors finally opened you found yourselves in a long golden corridor. Frisk approached a little golden star, and saved. Suddenly the world around you began to blur together as you fell onto your side, and everything faded to black.

You woke up in the golden corridor again, but Frisk wasn't with you. You looked down and saw a knife in your hand.

" Not this shit again.." you think to yourself.

You felt your legs walk forward towards silhouette of who seemed to be Sans.

" hehehe, that looks like the face of somebody who's been killed 10 times.." Sans comes into view.

" 10 times..? I just got here" You say in surprise.

" Oh, cut the shit Y/N, I thought I could trust you.. I loved you Y/N.." Sans says with a mixture of anger and sadness.

"L-loved me..?" You collapse and start crying right there, "I don't want to fight anymore..! I won't fight you!"

"Fine if you won't I will!" Chara says on your head.
