A human child wearing a blue shirt with pink stripes and blue shorts, has short brown hair was walking down on the sidewalk has a brown backpack on her back. Along with this child was a twelve year old skeleton girl wearing a green dress and black boots, has long dark brown hair with her bang off to the side covering her right blind eye socket. The human child look up and asked "can I tell you something"? The skeleton girl nodded and said "sure thing, Frisk". Frisk sigh and said "Coco, have you had a feeling that something is out to get you"? Coco turn to Frisk and asked in concerned "what do you mean"? Frisk look down and said "well, I been having these dreams for quite sometimes and mostly is the time where I was being prosiest by Chara. I don't think it's Chara at all that causing this". Coco eyes pupil disappear and she stop in her deep thought. Frisk saw Coco was in deep thought asked "Coco, what are you thinking about"? Coco eye pupil return and she turn to Frisk saying "sorry but I had thought about last week of what Gaster was telling me". Frisk look at Coco confused and asked "um... what do you mean"? Coco gave a soft sigh and said "well he's been telling me that way long ago before the war broke out between the two races was a demonic shadow who was second best because he felt that everyone hated him and didn't want nothing to do with him. So he decide to get the humans souls but the monsters stopped him and cause him to be banish from the land forever. But legends says that the demonic shadow is planning on returning back to the surface and wants the souls of humans who has very special kinds of souls". Frisk gulped and Coco saw Frisk worried look and said "I know it may be scary but Gaster never fables of anything. To me that this demonic shadow could be looking for you, it may be possible". Frisk look down and didn't say anything, Coco sighs and said "you know that Sans and Toriel would not let that happen. I wouldn't let it happen, even though if it means risking my life for it".
Frisk didn't say anything and Coco could see that Frisk was scared. Coco spoke up saying "hey, let's not worry about it right now. Besides it's best that you and I are the only ones know about it". Frisk nodded and said "I don't want anybody worry about me". Coco nodded and said "yeah, well come on. Let's get home before Toriel and Sans began to freak out wondering where we are at". Frisk giggled and said "yeah, let's go home". Coco and Frisk both began to walk back home, once they were both at their house which both of them live together since they came up to the surface. Just then Coco heard giggles behind her, as she was about to turn around that's when she felt someone grabbing her right leg. She look down to see a small lavender spider with two black picky tail hair and wearing a pink T shirt and pink pants. Has six arms and two legs which total of eight and has six eyes. Coco smiled and said "hey there Mia, what are you doing"? Mia look up at Coco and said with a smile "playing with you and Frisk". Frisk giggled and Coco began to laugh. Just then a high screech pitch noise was heard. Mia look over and said "oh mommy's calling us. I better go now, bye bye". Mia jump off of Coco's leg and ran to go back to her mother. Coco smiled shaking her head, "that spider, she's so adorable and cute". Frisk nodded saying "also adventurous". Coco nodded and said "she so small that you barley be able to see her". Frisk giggled just then a female goat wearing a purple dress and a white purl necklace she made two weeks ago and has fang showing from her mouth and floppy ears walk to the top of the steps. The female goat smiles and said "I was beginning to worry about you two". Coco smiled and said "sorry Toriel, we got a little distraction". Coco gave a wink at Frisk and Frisk smiles at her. Toriel smiles and said "Papyrus and Sans went out to get some grocery for me. They'll be back very soon". Coco nodded and said "okay, come on Frisk, Let's see what we can do to hump up our school skills". Toriel and Frisk both laugh at Coco's pun. Toriel shook her head and said "you're as good as your brother". Coco shrugs and said "ah... learn from the expert brother". Toriel let Coco and Frisk in the house first then she came in afterwards.
Frisk went upstairs dragging her bag on the staircase. Coco went into the small living room with two rocking chairs, a blue couch, and a coffee table made out of glass. Coco flop herself down on the couch and put her legs on the couch and looked as if she was down to the count. "Aw... feels good to be home for the weekends". Toriel shook her head and went into the kitchen to cook for supper. Frisk however put her bag on the side of her bed and sat on the bed thinking about earlier of what Coco telling her about the demonic shadow. Frisk thought to herself "I wonder if this demonic shadow is the one causing my dreams, if so how he knows about me and Chara"? Frisk just couldn't shake the feeling off of the dreams she's been having past couple of nights. Frisk got up and went into the next room which was Coco's room and look at the three full shelves of books. Frisk knew that all the books are full of either fairy tale or non fiction books about the history of Underground and the surface. Frisk wonder if Coco has a book talk about this demonic shadow. But each book Frisk look, no book on the demonic shadow. So Frisk went back into her room and sat back down on the bed, she grab her bag and put it on her bed and zip it open. She pull out a science book and a notebook. Frisk put her bag down and lay on her bed to work on her homework.
Later that night everyone was all sleeping. Frisk however was tossing and turning in her bed, having a horrible nightmare. The one she's been having each night but this in particulate was the worse.
Frisk saw herself in pitch darkness, not knowing where she was till she heard a filmier male's voice, still unsure who it is. The voice said in low tone "I know all about your determination Frisk, you can't hide from me. No one cares for you, everyone hates you. Remember how you and that comedian fought in Judgement Hall". Soon a window image appear in from of Frisk, a image of her and a small skeleton wearing a blue jacket a white shirt inside and pink slippers, name Sans being in Judgement Hall. Frisk sees that she was being control by Chara. In the image Sans' right eye socket was deep blue and was using his gaster blasters at her. Frisk remembering what happen was frightened and tried not to watch but it was hard. Then everything around her began to change and soon she saw that she was on the pile of yellow flowers. She recognize where she was and soon a female voice was heard. Frisk smiled knowing this voice, she turn around to see Toriel looking at her. Frisk smiled and said "oh mom". Frisk was about to hug Toriel when all of sudden Toriel began to attack her with fireball. Frisk dodge the fireball and yelled "Mom, what are you doing"? Toriel didn't answer and soon Toriel began to change into a dark shadow looks to be a man figure with bright red eyes in the middle was a black cat pupil eyes. Frisk not only in shock but terrify to see this shadow figure staring at her.
The shadow laugh and asked "how was it Frisk? Was it terrifying to see one of your own family trying to kill you"? Frisk stood up with Determination and said "you were pretending to be my mom. Mom will never hurt me and Sans made a promise to me that he won't hurt me again". The shadow laugh and said "oh Frisk, you still don't get it do you"? Frisk look at the shadow and asked "w-what do you mean"? The shadow said with his eyes pupil moving to one side of both of his eyes making Frisk being creep out, "don't you see? No one will want you around, everyone hates you". Frisk cried out with tears flowing down on her cheeks "no, your wrong! That's never going to happen again"! The shadow said "well you may say that now but I assure you that no one wants you specially after what you've done to them all. The only ones you never killed is Sans and Coco". Frisk began to cry and said tearfully "you're a liar, just like Chara". The shadow laugh and said "I know her very well. The first human to fall in the Underground". Frisk didn't bother to ask, she was still upset at what the shadow said to her. The shadow said with his eyes pupil moving to one side and to another, "face it Frisk, you can keep on saving everyone but it won't last forever. You and I know that. So just RESET... so we can be the best of friends". Frisk look up at the shadow and yelled "No! Never I will RESET again. I promised". The shadow said with irritation "very well then I have no choice but to steal your soul". Just then Frisk began to feel pain inside of her body and soon she look down to see some vines wrapping around her. It made her remember of Flowey and the way he done it to her. Frisk tried to fight but she was unable to free herself. The shadow laugh evilly and said "now do you understand what I'm trying to get at". Frisk struggle and soon the vines began to wrap itself tighter that cause her to scream in pain.
Frisk woke up to find herself crying in her bed. She sniffled a few time and wiped her tears away. Soon the door to her bedroom open and the light of her room came on, Frisk turn to see Toriel and Sans running to her side. Toriel asked worryingly "oh my child, are you alright"? Sans look at Frisk and ask "jeez, kid what happen to you"? Frisk sigh and said "I had a bad dream". Toriel sigh and said "don't worry my child dreams don't always come true". Sans ask with worry "do ya wanna talk about it"? Frisk shook her head and said "no, I don't". Just then a tall skeleton wearing an orange T shirt that says "Cool Bro" on it has red boots came in worryingly asked "what happen? Is the human alright"? Sans look up and said "don't worry Papyrus, the kid just had a bad dream". Papyrus walk up to Frisk and said seeing that Frisk was crying in her sleep "don't worry human the Great Papyrus is here for you". Frisk smiled and began to giggle which made Toriel and Sans feel a little bit better to see that Frisk was feeling better. Papyrus look at Frisk and asked "human do you want to sleep with me tonight"? Frisk nodded thinking that maybe if she's with Papyrus nothing will happen to her. Papyrus smiled and said "okay human, I'll carry you there myself". Papyrus picked Frisk up and carry Frisk in his arms. Sans smiled and said "I think that if Frisk is with someone as cool as you bro, then she's safe". Papyrus smiled and carry Frisk out of the room and took her to his room. Toriel sigh and turn to Sans and asked "Sans, do you think that the dream she had could be dangerous"? Sans shrugs and said "don't know, the kid is too scared to even speak". Toriel and Sans walk out of the room and went back to their rooms to sleep.
Meantime in the other room next to the door leading to Frisk's room was Coco. She heard everything on the other side. Coco sighs and said "poor Frisk, I wish I knew how to help. I wonder if this demonic shadow legend is all true". Coco didn't know what to think but had a bad feeling that the worse is not yet over. She went back to bed and soon fell asleep but deep in her heart that something bad was going to happen tonight. Though she didn't know what.
