Transported To Different Multiverses As My Undertale OC.

NaJ 1

Caster was pissed, they had just gotten to a good point, they were in therapy, had friends, had a new family. And it. Was. Ripped. Away. AGAIN!! They screamed in anger and sorrow, pitch black flames bursting from every bone, burning the strings. They flew a bit more before falling into a new Multiverse, and passing out. Inside the Multiverse, a certain scarred skeleton looked up to see a small child falling from the sky. Panicking they teleported up and caught them, before teleporting back to the ground. The kid was... so small, who were they, and why did they fall out of the very literal Sky? Not knowing was else to do they took the kid to the hospital, this was going to suck to explain. 

== Time Skip ==

Much later, Caster woke up in the hospital bed their eye lights dim and lifeless. Error or as you may have guessed by now Mr. Erratum, was sitting next to him and began explaining how they got there. Of course Caster wasn't listening they knew enough, the rest didn't matter. A strange eerie silence filled the room, as if a volcano was about to erupt at any second.

Erratum: "So are you like me or did something else happen?"

This actually caught Caster's attention, and they turned to look at them.

Erratum: "I was beaten and thrown into the void in front of my family. I don't know what happened to them or the multiverse I came from."

Caster didn't say anything for a bit, processing everything, everything that happened to them and to this Error. It was a different kind of silence that filled the room, not eerie just awkward. Caster wasn't sure what else to do so they laid down trying to sleep. Maybe this time they'd wake up and everything would be a dream. Of course, they woke up in the same place they fell asleep in. Much to their dismay, frustrated and angry they teleported away to somewhere randomly. Ending up on top of a random school building, Caster sat watching the clouds roll by gingerly. What Multiverse were they in now, that was the real question. Depending on that and how long it would take for that ass Fate to find them again. They were probably going to be in a weird position for a bit. As the school bell rang out the students started to leave in a bit of a hurry. Watching them Caster saw a few familiar faces, and some not so familiar but known ones. They watched as and took note of who seemed to be a student, and instantly realized it was a NaJ Multiverse. Yea... no they were Not going to school, screw that. Though they did remember that Horror was supposedly abused by their father, so they decided to follow them and see.

It really didn't take long to confirm the abuse, but Caster's titles probably wouldn't let him kill the dick. Then again the dick's actions may let them get away with it, unsure what to do Caster recorded the whole exchange through the window. Sending it to the Police anonymously as well as a picture of the address. Due to the nature of the abuse, being verbal, physical, and sexual. The police were very quick to arrive and take control of the situation. Of course the father was arrested, and when asked if Horror had a place he could stay he nodded and called Mr. Erratum. After a few minutes Erratum arrived, talked it out with the police and the police left with Horror's father. Caster was feeling pretty good about the whole thing and went to leave, alone to be caught be Erratum's strings and dragged over.

Erratum: "Why'd you leave the hospital?"

Caster: "I don't know, maybe I'm pissed off I was ripped away from my family and friends TWICE~! And maybe I needed to clear my skull a bit!" 

Erratum: "Twice...?"

Caster: "YEA 🛳🕨🏖🏙🏜!!!"

Erratum: "Webdings?"

Horror: "A... royal font?"

Erratum: "Kid I don't know what happened and I'm sorry. But you can't just run around on your own."

Caster: "Why not?"

Erratum: "Cause you're a child?!"

Caster: "Only cause I don't age~! Though I'm probably emotionally a child too..."

Erratum: "My point proven you can't run around by yourself, why not come with me?"

Caster: "The fuck~!? Why?! You don't even know who I am?"

Erratum: "You someone in need of help that's all I care about."

Caster: "Fate's after me, or a Fate. You sure you wanna be near me... considering who you were?"

Erratum froze, a Fate was after this kid?! No way in hell was he leaving them alone now.

Erratum: "Yea you're coming with me, no way in hell I'm leaving you alone so Fate can steal you away."

Caster: "Yea, good luck."

One teleport later and they were all in Erratum's house, a nice cozy..... 5 story mansion. Yea okay, this wasn't what either kid was expecting at all. Why was the Erratum's house so huge?! Maybe cause it reminded him of the Anti-Void? Hmm, who knows, the bright side, Giant ceilings to swing around the house with! But that could wait till tomorrow, right now, everyone was tired. Well almost everyone, Erratum didn't sleep usually. So he'd probably be up all night as usual, the real issue was, he had work tomorrow and Caster couldn't be left alone. A fact that was reinforced when Erratum caught Caster cutting. Jeez this was going to be a lot of work, but... Erratum was determined to protect the kid from Fate and give them a good life. Even if it meant taking their place and going with Fate if it came down to it.
