A/N: I don't own RWBY or Undertale. In other words, I'm not Monty "The Magnificent" Oum or Toby "Mr. Radiation" Fox. I wish I was either of them...Anyways...still don't know what to call this story so I'll worry about it later. In the meantime, enjoy the story.
Frisk woke with a start yet again. She had been having recurring dreams of her brother committing genocide against all of monster kind, and her small amount of determination could do nothing against his rampage of insanity.
She then remembered who she was thinking about.
"Chara," she called out, whispering at first.
She looked around as she called out for her brother.
"Chara, where are you?"
She heard a grumbling noise to her left. She noticed she had been lying in a rather fluffy and comfortable bed. She looked to her left and saw the familiar disgruntled face of her brother. He seemed older...taller...more...hairy. He had a strange scruff around his chin and little hints of hair on his jaw line. His hair on his head had grown into a very much more defined bowl-shape.
She then looked down at herself and noticed a strange feeling of heaviness as she tried to sit up on the bed she was in. She noticed that she had...matured...slightly following her time in the underground.
She looked around the room again and noticed that there was a third bed in the room. After reassuring herself that her loose-fitting nightgown was actually going to stay on her, she slowly wandered towards the other bed, not wanting to wake anyone.
As she got closer to the bed, she noticed a familiar shape. A human skull. She looked closer and, sure enough, the blue light emitting from the left eye socket assured Frisk that it was, indeed, her old friend Sans. He was sleeping peacefully. There was no doubt in Frisk's mind that Sans was dreaming of Grillby's, his favorite diner. There was something different about Sans too. He was missing his worn down parka and his old blue jeans. He had also gotten a little bit taller. Frisk's suggestion to drink milk instead of ketchup had been working well for him.
"It seems you are awake. I am pleased to see that you are finally showing signs of life. It seems your friends are still partaking in beauty rest. Shall I wake them up?" A voice said behind Frisk, making her jump and hurriedly scramble back to her bed.
The voice chuckled at her childish actions.
"Relax. I'm not here to hurt you. I'm friendly."
Somehow, finding her voice, Frisk said, "Th-the last time someone said that to me, I was almost dead after trusting them."
*Remembering your first encounter with Flowey the Demonic Flower still chills you to the bone. Regardless, you are filled with DETERMINATION.
"Ah. I'm sorry to hear that. Would it be any comfort to you if I revealed myself to you?"
...
"I suppose."
A man in a green tailcoat walked in, coffee mug in one hand, cane in the other.
"I am Professor Ozpin. Headmaster of Beacon Academy. You are currently here in Beacon in a special ward for severely injured or special patients."
*Remembering your unknown reasons for being here, you begin to worry where Sans' brother, Papyrus is. The worry shows on your face and your DETERMINATION drains. You have temporarily lost your ability to save.
"Is something troubling you?"
"Y-yes...Miste-Professor Ozpin. There was a taller skeleton of about your height with a tendency to say "nyeh-heh-heh" with us. Have you seen him nearby?"
"Yes. Of course. That one. He has been moved to his own separate recovery room so he doesn't disturb the healing sleep of the other patients."
*Now knowing the whereabouts of Papyrus, your DETERMINATION refills and you have regained the ability to save. The relief is shown by your expression. You may not want to lie to Ozpin soon, because he seems to be able to read expressions well.
"That being said, I haven't been introduced formally to you and your friends here. Would you care to tell me of your little group?"
"O-of course, s-sir."
"Just call me Ozpin. It's fine."
*Ozpin gives off a calming, fatherly aura. Your MERCY actions have increased percentage of working on enemies in this area.
"Well...I'm Frisk. Frisk Dreemurr...I climbed to the peak of Mt. Ebott and fell into the Underground, a world underneath our own full of monsters. These monsters were actually very friendly, save for a few murderous robots, demonic flowers and Annoying Dogs. The Underground was where I met the two skeletons who are here with us, Sans, the one in the room with us now, and Papyrus, the taller one who says 'Nyeh-heh-heh.' Long story short, I saved the Underground from certain doom with the help of the friends I gathered along the way and the continued support from my brother, Chara, who can be a little...not right in the head...sometimes. The barrier keeping the monsters sealed in the Underground was broken and the monsters began to live in society again, but I'm not even sure what year it is anymore, so I don't think I can go back and save who I had left behind."
"That is indeed a lot to take in. If it is any help to you, It has been about nine year since the monsters...erupted...from Mt. Ebott. Mt. Ebott is actually right behind Beacon, so we were the first people in the world to experience these so called "monsters." They were rather pleasant creatures. I am especially worried for a pair of strange goat monsters that were looking for..."
Ozpin stopped for a moment, shocked.
"Two eight-year-old children. One, a girl in a purple and blue striped sweater, and the other, a boy in a green and yellow striped sweater. Ms. Dreemurr, it's been nine years since your arrival here. I'd tell you of your current situation, but I'm afraid you already know what you want to do."
"I need to find those goat people," Frisk said, determination filling her voice.
*You look around to find that no one is rousing to come and help you. You feel somewhat embarrassed and your dodging speed has gone down by one level.
"So are you planning on going out in that hospital gown, or are you going to come with me to retrieve your belongings, Ms. Dreemurr?" said Ozpin expectantly.
