Prologue

A long time ago, humans and monsters ruled the surface in peace. Everyone got along and there was no fighting. Until the Human Monster War. No one knows why the war started, the Human government won't tell, but rumors were spread that a monster absorbed a human's soul and turned into a beast, one who was not human nor monster. Anyways, the Human Monster War raged on for around a year. Before the war the monsters had over a million monsters who lived in America. During the war, the monsters could never defeat one human while humans killed over 99% of monsters, whether fighters or innocent bystanders. Eventually the monster king was killed and the crown prince, Prince Asgore Who was recently made king, was forced to surrender to the humans. The remaining monsters, around 5,000 monsters, were forced underground behind a magical barrier created by the best group of mages at the time. Many still say that the monsters will one day break free from their prison and enact another war on humans. Whether that is true or not, rumor has it that a few monsters were able to escape imprisonment, many of them have been executed or possibly put into another magical prison as rumors say, but there still might be monsters lurking around around the surface today.

(Frisk POV)

My teacher just finished reading to us about the Human Monster War. As if we hadn't learned anything new about it since kindergarten and now I was in eighth grade.

"Do you think there are any monsters around this area?" A boy in black asked hoping to drag on the conversation until the period was over.

"Actually, lately some have been saying that they have seen a small yellow scaly monster in Ebott Forest. So it is possible, and if you do see anything that might be a monster please report it right away. And that does not mean to dress up John like a monster again and try to get him in trouble." Mrs Vinciana warned looking at the group of boys in the back who did that and they just looked away. I had a look of worry flash over my face and Mark looked at me with a suspicious glance. I always hated Mark as he always tried to bully me and one time he tried to stab me, but I couldn't prove it and my family didn't care. And it was during gym class, for fuck's sake! I just hope that he didn't try the same thing with the monster.

"If they find him kill them." A voice and my head tried to tell me but I ignored it. I always ignored it as it always tried to make me hurt others. That just wasn't me.

The bell then rung and we all ran out the door to get out of school. Nowadays everyone called me insane for going out into the woods everyday after school but I knew I was safe. How you ask, would I be safe, when there might be a monster? Because that monster is M.K. and he's my best friend. I was on my way to his hideout deep in the woods and I heard screaming. The voice sounded familiar so I went to check it out. I followed the screaming to the top of the mountain and saw M.K. in ropes held in place by the boys in my grade and saw he was gagged. they were getting near a hole in a cave near the summit. For some reason the boys were wearing hoods but I didn't care for the reason.

"Leave him alone." I yelled in anger as the boys looked at me.

"Oh look, Little Miss Shy is yelling at us. I feel honored." One boy smirked not even flinching and one boy went to hold me back. I struggled to break free but I couldn't.

"Oh, this is the reason you're always in the woods. You, little miss imperfect, found a monster. You would have been given a medal had you not been friends with this thing." Another boy spat and hit M.K.

"What did he do wrong? He's only a kid." I cried out desperately still struggling as M.K. struggles in the ropes

"He's a monster what other reason do we need?" The Leader said, who I recognized as Mark, "Throw him down."

I watched in terror as the boys pushed M.K. down a deep hole in the mountain and laughed at him.

"M.K!" I screamed at the top of my lungs and broke free but couldn't reach him in time and started crying as my best friend was probably dead.

"Now listen hear Frisk, you won't tell anyone about this or else we'll tell everyone that you were hiding a monster. Got it?" To which I numbly nodded as I was still in shock at M.K. dying. I felt tears flow down my face for a few minutes before I decided on something. Or instead something decided it for me and I listened.

"They'll pay. Humans and Monsters. If they hadn't fought then M.K. wouldn't have died. They'll all die by your hands." The voice tells me playing on my grief and this time I agree. Humanity would die. Monsterkind would die. I thought this while I remembered the first time I met M.K.

(Frisk Flashback)

One day when I was on a picnic with my family I decided to go explore the woods near our mansion. I thought it was a good idea and I would prove my siblings wrong and be brave by going alone. I happily skipped through the woods humming happily as I went along. They always told me "No don't go there, Frisk there's scary monsters that will eat you," and then the other would scare me. Now I was going to show them wrong and monsters wouldn't eat me. It was all fine until I heard a branch snap.

"Who's there?" I whimpered out in terror and realized that my siblings were right and that I was weak. I saw a bright yellow tail flash in the bushes and it seemed to be shaking in fear.

"It's okay I don't want to hurt you." I told it while slowly approaching.

"P-promise?" It asked in fear and I nodded trying to seem brave.

"Yeah. I don't want to hurt anyone." I smiled and noticed the tail stopped shaking and slowly I saw a creature come out of the bushes. It looked like a small lizard like yellow creature with a scaly tail. He looked to be my size as well.

"You won't hurt me r-right?" He stuttered out in terror.

"I just said that silly." I smiled before giving him a hug. That was when our friendship began.

Every week I would sneak out to the woods to meet with him and play until the day we were found out. The only time I wouldn't go out to play with him was the week of my birthday, but that was because our family always took a vacation that seven years but my friend was gone. Now all I could think of was ways of making everyone pay the price for hurting my best friend.

(M.K.'s POV)

I hit the bottom of the hole rather quickly. I could feel my soul cracking. I knew that soon I would turn into dust, that's how every monster died, or so my parents told me before they died. The last thing I heard before my soul shattered was a voice scream in terror, "where did this kid come from? The Surface? oh god he's at 0 HP!" And then I felt myself fade into dust as I heard cries that tried to comfort me as I faded.
