A skele-fun reincarnation (Roxy x M. reader but sans)

The soul reason I'm growing so strong

In the land of furrys I mean Beastkin Eris was playing with the children you, her, and Ruijerd saved.

Minitona: "Meow! You done it meow, Eris! Eris have so much muscle! Wow!"

Eris: "Hey! Not there! That tickles!"

Meanwhile you look at them to see what the noise was about.

(F): "Yup, that's Eris. Anyways, I wonder what this is.. It looks like a glitch, I have heard about different Sans AU's but I never got around to researching them. I wanted to complete the game before that, but I died. Maybe this is something like that, I've gained new abilities that reference another Sans AU."

Gyes: "What is that?"

(F): "I call them Gaster Blasters. They shoot high power magic beams, their power comes from my special magic source."

You activate your eye and suddenly you start to see him in code. You quickly deactivate it.

(F): "What was that? Actually never mind. We'll talk later. I need to do research on this."

Gyes: "I see. Good luck young (F)."

You teleport to a further part of the forest that was more open.

(F): "Let's see what this is all about."

You activate your left eye and begin to look around, a lot of things were silhouettes made out of red, green, and red code.

(F): "This is weird, and that's saying a lot. I wonder if I can do something with this.."

You get near it and you see something.

(F): "Is that, a string?"

You reach forward and it suddenly shoots at you. You jump back but it was to late, the string was making its way to your chest, there is ingulfed your soul and make it anew. You look at it, it was a upside down red heard made out of string and there was a glint of white in the middle, it emitted a red glow.

(F): "What even happened? Why do I feel a strange connection with this code? Never mind this, everything, I can sense it all. And these strings. What are they?"

You put a hand to your eye and pull it away, red strings come out of your eye and are attached to the tips of your fingers. You slash at a nearby three and it slashed clean through.

(F): "Woah! That's sharp.. Hmm. If I can use these strings that means I can interact with the code in some way. After all they came directly from it."

Placing your hand on the code you can feel its movement and actions. Focusing on it you try to edit it but get shocked and slammed against a tree. Opening your eyes you see your in a black void. You get up and start walking around, seeing a screen you walk next to it and look at the world your in, you were knocked unconscious.

(F): "Damn. Guess I can't edit code then. Maybe I can-"

You were cut off by something falling on the floor, you turn around and see the man that helped you before.

(F): "What happened to you?"

???: "The same thing that happened to you, I was changed. Now I have more power over different things."

(F): "So what are you doing here, Gaster?"

The man stood there, melting.
