A/N: I need to do this. I've has this idea in my head for too long, and now I must put it out for the world to see! I am DarkX the Dragon Knight, and I've become too obsessed with Undertale for my own good! But, who hasn't lately, right? I mean, you've probably heard this about a hundred times, but Undertale truly is a great game. And that's why I'm here- to bring you a story that goes past the True Pacifist Ending, above Mt. Ebott, beyond the Underground!

...Sorry, I got caught up in the moment. So, let me give you a few warnings- yes, this takes place after the True Pacifist Ending, so there are going to be spoilers. There might be some references to the Genocide/No Mercy Ending, so there will be spoilers there if that's the case. And finally...some other third thing. Use your imagination!

And now, without further ado, are you ready? The adventure begins on three!

One, two, three, GO!

Chapter 1: Strike

Humans.

Monsters.

They couldn't possibly live together on the surface again, right? After all, the monsters had been sealed underground ages ago. Longer than most humans could remember. Some even doubted monsters existed to begin with. Who could blame them? There was hardly any trace of the monster race left on the surface. Those that had seen monsters, by falling into the Underground through the infamous Mt. Ebott...never came back.

Except one.

That was when everything changed. Somehow, when that human child fell into the kingdom of monsters, the barrier sealing them beneath the surface had been shattered. This allowed all of monsterkind to appear on the surface- in the world of humans. They weren't hostile, however. No, if anything, they wanted nothing more than an era of peace between humans and monsters. At least, that's what their king said.

Remember that child mentioned earlier? Well, believe it or not, they became the monsters' ambassador to the humans. Odd how a child, of all things, could take on a job like that. Perhaps it was the fact that they had spent so much time with them (and was possibly the reason for the barrier being broken- but how would humans know that?), it only seemed fitting. Of course, helping monsters become integrated into society wasn't easy, but that was to be expected. The War of Humans and Monsters, remember?

Eventually, the two races had come to peace agreement, and we're now living together in peace. Well...sort of. There were humans that accepted the monsters' arrival to the surface, and humans that didn't. Again, that's to be expected- aside from the periodic protest, speech, vandalism, things like that, nothing got too out of hand.

That is...until there came to be a third group. This group didn't just 'not accept' monsters like the others. They hated monsters. With a burning passion.

A Loox strolled through the city streets. The moon shone overhead, basking the vacant sidewalk in its light. Since it was so late at night, there wasn't much activity around...

That also meant no witnesses.

A pair of figures stood a few kilometers in front of the one-eyed monster, hidden by the shadows. They stood at opposite ends of the street, ready to intercept. As soon as the Loox was between them...that's when they struck.

One of the humans stepped out from behind a lamppost and pointed a revolver at the monster. She fired twice- one bullet collided with one of the Loox's horns, and the other grazed the top of its head. The monster yelled in pain, shocked by what just happened. While it was in this state, the second human sprinted out from the shadows and pierced the monster's back with a machete.

Being unable to fight back, the Loox became nothing more than a pile of dust on the concrete within seconds. Both humans stepped back, looking around to see if anyone had witnessed the attack. To their relief, there was no one else around. Without a word, the duo ran off into the night. Where? That was the question, wasn't it?

Beep beep beep-

Frisk moaned and slammed their hand against the alarm clock. Since they weren't looking, it took the child several attempts before hitting the correct button and shutting off the alarm. They yawned and sat up in bed, rubbing their eyes. They soon remembered- it was Monday, and that meant school.

Frisk hopped out of bed and went to get ready before breakfast. They soon ran downstairs, now wearing their signature blue and purple striped shirt.

"Good morning, my child!" someone greeted cheerfully. Toriel stood near the dining room table, where a fresh breakfast of pancakes sat. "I hope you enjoy the new recipe I used. I was finally able to find one where I could use snails in the best way!"

As the goatlike monster left to finish getting ready, Frisk ate the pancakes. Most people would think eating anything with snails in them was gross...yet, somehow, Toriel managed to make them quite tasty!

Once breakfast was done, it was time for the Frisk and Toriel to make their way to school. Since the latter worked there as a teacher, she figured Frisk might as well tag along with her. Besides- much to the child's dismay, it was impossible to skip school when your adoptive mother worked there. Still, Frisk didn't mind walking with Toriel, so that was a plus.

"Hey Frisk! Hi Ms. T!" a familiar voice called. The yellow, armless monster child ran up to greet the pair as they approached the school- and faceplanted onto the ground as he did so. He quickly picked himself up and ran up to them as though nothing happened.

"Hi!" Frisk replied happily. Toriel (who was called 'Ms. T' by the students) waved in greeting.

The young monster turned to Frisk and asked, "Hey, did you hear about that attack that happened last night?"

Frisk blinked in concern. "An attack? Last night?"

The monster child nodded. "Yeah! My sister said it happened on the street behind the park. Really late last night, nobody around or anything-"

"That's enough," Toriel interrupted gently. "Now is not the time to be discussing this."

"Oh. Sorry!" The monster child replied apologetically. "See you in class, Frisk!"

As the young monster ran off into the school (faceplanting once again), Frisk frowned. These attacks had been going on for weeks now, and there had yet to be any solid evidence of who the assailants were. It had been worrying the child since it began- they were the ambassador. They were supposed to help monsters and humans get along...and now this was happening...

"Frisk? Are you okay?" Toriel asked, concerned. The child turned to her and nodded. Frisk didn't want Toriel to know they were worrying so much about this. The former queen worried enough about the safety of Frisk and her students since the attacks began, and the child didn't want to be cause for any more concern.

Toriel blinked, as though she could tell Frisk was lying, but nodded in response. "Okay."

As the two of them strolled up the path to the school, Frisk couldn't help but think about these attacks on the monsters. Who would be the next target? When would these assailants strike next?

A/N: That's all, folks! I gotta say, I liked how this turned out (And I REALLY hope I characterized everyone well)! I'm really looking forward to writing this story! GAH, SO MUCH EXCITEMENT! Anyways, I hope you guys enjoyed the beginning of something great! Get ready for cuteness, bad puns, and FEEEELS! But, that's Undertale for ya, right?

See y'all in the next chapter! Buh-bye!
