This story is inspired by many other works and may bear some resemblance in certain places. However, I will endeavor to make this story it's own.  


2 years ago monsters were released from the underground, ending their centuries-long imprisonment at the hands of ancient humans. 

Not a soul remains in the underground.

But that doesn't mean no one's there. 

Be it chance or fate, The First Fallen will soon meet an all too curious human as he ventures into the deep beneath. 

The Reader or [Y/n] is male and Chara is female.
 I apologize if this bothers you it's just how I've always seen the character. 

Disclaimer: I don't own these Chara-cters nor do I own Undertale. This is just for fun.
This story's rating is [M] for explicit language, violence, suggestive or sexual themes, and fantasy/fictional violence.

My lovely reader @NightTheDemon1 told me that the artist of the cover is a Twitter user known as
@A___IRAA. Thank you!

You've been doing the same True Pacifist / Pacifist Run over and over in a place called the "Underground". Though you like the Underground, you can't help but feel weary.. Every time you [SAVE] everyone, the World just..[RESETS]... And with that, you're back at the beginning again. You just want to go home... Why won't this "Underground" let you leave? ... Well, if you can't leave... Something 'new' should happen sooner or later, right..? (You hope that something exciting or different will happen in the Underground.) (You are filled with DETERMINATION.) --- ;) ~~~Disclaimer: I don't own those (MULTIPLE) pictures used in the Cover. I just mixed them up for a spicy cover. ( ͡° ͜ʖ ͡°) Mash-up covers are the best. ;') (I spent up to 3 hrs mixing stuff around + editing + adding light and shadows...*Dies*) If you have a problem with the Cover, I'll change it.
Kindness 《Undertale》[Completed] by Maela_Bow
10 parts Complete
It had been less than a day after your best friend Chara, had gone missing. You were already really worried about her (Chara is Female in this) The others didn't look so worried but that's because you and Chara were pretty much slaves to them, although you thought that everyone has some sort of kindness within. You then decided to go to the only place Chara ever wanted to go, Mount Ebot. So this isn't a full on Sans X reader, it does have it in it so there that. But I'm sure it'll get better along the way. So most of the art in this is going to actually be mine, the art I used for the cover, is not however. The credit for that art goes to the actual artist. The music I use isn't mine either. I do NOT own Undertale (Though I wish it did) It belongs to Toby. Also there might be some swearing in this... MIGHT.
Remembrance - An Undertale Story-DISCONTNUED by MEJ2235
8 parts Complete
Long ago, two races ruled over the Earth. Humans and monsters. At least, that's the story we all know. There was another race. Technically, they were monsters. Skeleton monsters to be exact. Humans shunned them because they were monsters. Monsters shunned them because humans had skeletons. In retaliation, the skeletons split into two different races. The Surface Skeletons and the Abyss Skeletons. The Surface Skeletons reaches out to both monsters and humans. However, when the war started, they were some of the first monsters attacked and many were killed when they fought with the other monsters. Only a handful were sealed underground but without the Sun to strengthen their bones, the skeletons suffered until they received anonymous help. Very few survived to this point and slowly, they died out. The Royal Scientist at the time and his wife tried to have children. Each time left them severely weakened. Each child dusted until the wife gave up her life to bring a great skeleton into the world. That child is the last of his kind. The Abyss Skeletons shunned all other monsters and humans, considered them all demons. Their society was alike human society long ago. Divided. They believe they are strong and emotions only weaken. The class system was rigid and they possessed a kill or be killed attitude to all other monsters and humans. They thrived underground and ended up building their society in the Underground's own Abyss. It is a shame that only their leader can reclaim their heir from the corruption caused by those demons. Warning: Rated Mature for possible smut and probable gore. I'm sorry I don't know what I'm doing but this ain't for little kids. Also, cover doesn't belong to me. Credit to creator. Found it randomly when I searched up Undertale.
No Chocolate - Chara X Frisk by mellophor
57 parts Complete
DRAMA, ACTION, BLOODSHED... Love? After erasing hundreds and hundreds of timelines, Chara is suddenly stripped of her abilities. She's forced to lead an everyday life in a world unknown to her, but that doesn't become a problem because Frisk, who just fell into the Underground, makes her forget everything, focusing only on their emotions and the chemistry between them. Chara and Frisk will go through good and bad together. They will have to protect each other from "the external factors" lurking in the shadows, and their teenage desires which they can't control~ All chapters labeled with "~" are exclusively lemon and unrelated to the main story. Go there if you want to have some fun ;) ""YOU HAVE NOTHING TO SAY HUH? THAT'S WHAT I THOUGHT." Frisk was uncomfortably close to me, even though she's a girl, she doesn't know that I'm gay as fuck for her." *IMPORTANT INFORMATION* - Chara (16/F) x Frisk (16/F) - Emotional and gruesome scenes - Sexual interactions and moments - Rough + gentle switch lemon

Betrayal of Euphoria «Book 1» by xHaunting-Whispersx
10 parts Complete Mature
"I'm bleeding...but it seems as if my fears have vanished as I stare at the male before me. He gazes at me with such intensity and I can't help but feel...compelled by his alluring crimson eyes. A feeling of felicity bubbled within my stomach. It was weird...since this man kidnaped me and all, but...I wasn't afraid-not a sense of qualm within my body. I was relaxed and eased...I wasn't afraid, which I guess, made me enjoy his presence. He was a God and I was the measly beggar before him...Oh, how I just wanted him to hold me...wait...what am I saying? "'Snap out of it Blu! He kidnaped you! This isn't some Stockholm Syndrome thriller! He's going to kill you if you don't do something!!'" Despite the edge my conscious clearly announced, I felt at peace. I was happy-no anxiety, no sadness...just bliss...he treated me well and I loved him...but, did he feel the same?" - This is kind of like an AU? Like Chara is an actual human not a video game character, along with Frisk who pops in or is mentioned a few times throughout the story. This story contains smut (it's shitty regardless, lol) and swearing, maybe, and it's between two males. If you're not into gay stuff, then this story is not the right one for you. :) It's also written in third person, not first person, like the description is...oops? Disclaimer: I do not own Chara or Frisk, I just own the plot and the character Blu, his family, and that's about it...

Frisk x Reader by TeamFreeWillCCD
23 parts Complete Mature
The year is 20XX. A human has fallen from the surface world! She was running from her abusive home when she made it to Mt. Ebott. However, when she looked behind her to see if she was followed, she forgot to stop running. Needless to say she tripped and fell. However, she was not caught by the ground, instead she kept falling. When she landed on a patch of yellow flowers, she heard a voice. She began to freak out watching a figure approach her as she fell unconscious... Hello everyone! It's been a bit huh? Yup it's an X Reader fanfic! I myself read these types of stories because I'm a lil' lonely but also a lot of them are really good! However, when I went looking for Frisk x Reader stories I found that most of them were Male Frisk(/Chara) x Female Reader, or visa versa. I was looking for a Female Frisk(/Chara) x Female Reader. I didn't find many at all. Therefore, I have decided to write one myself. Hey guess what? THE COVER IS ORIGINAL!!! I actually did this one on my own and was proud of myself because I think it looks pretty decent! TBH I don't quite know what's in store for this one... I didn't plan this one like I did Danvid.........But Also Dadvid. So let's see how this goes together shall we?

WRONG (FlowerFell FanFiction ) by tmntrebeka
21 parts Complete Mature
"Everyone has their story, but ours is no fairytale. We lived it. We both endured it. God, I just wonder why it all went so wrong..." "Not all of it did, Sans. We had our moments. The special things in our lives. We just always were... in the climax of life." "That was Hell. You lived a life of Hell, Frisk." "We both did..." "F*ck it! If you want to know our sh*ty life story then go ahead, but I ain't any story teller so don't get mad at me if you don't like it!" "Sorry. He doesn't like to talk about our past. We never had it easy." ------------- This is a FlowerFell fanfiction. It contains violent events, blood, and swearing. This NOT whatsoever a lemon. Pictures not ours This book was Created, and Edited, by Shu0904, Wolfgirl62250, and me. Its a bit ruff around the edges, but that is because this book has come from a Roll Play, (also known as RP) A RP is more or less LARP, (Live Action Roll Play) Its like Dungeons and Dragons, but we have done it through chat. This makes it were we can create our own story line, and thus it can be based in anything. This RP (book) has took almost 2 years to make. And frankly, just sucks. Read at your own risk. -All Rights Reserved- ------------- This is a book of back story, or more of a preview to the book series "Wrong".

Many years ago there was a war between humans and monsters. Although monsters had inborn magic on their side they were sentenced to live in the Underground, seperated from the surface by a barrier of human souls. The monsters have broken through the barrier and now wish to live among us. Duska watches from her room as a reporter interviews King Asgore on the TV, wondering how life will change for her. Now she lives with two monsters. How much will her life change? Can she reveal her deepest secret to them? Will she find more about herself? Will she fall in love? (Undertale does not belong to me, only Duska does. The songs linked belong to their respectful owners and so does the art. There will be swearing and strong themes. Please enjoy!)

It's the same beginning. Isn't it always? (Y/n) is a neko (a cat-like human) who has fallen in more ways than one and will now have the pleasure of being stuck in the Underground with the Master of Flirtation, the Pie Queen, the almost Psychotic Ghost and other somewhat funny names for the rest of the monsters in the Underground. Let's see where this goes... Nowhere good I suppose? Oh wait! Don't some people leave a paragraph from the story in the description? Let me just... "I was about to turn back and hide when another shot rang and came right towards me. Without thinking I moved back to dodge, and I did dodge the bullet. Only I went down instead of to the side. So here I am, falling with only one thing on my mind... 'Will I land on my feet?' " There ;) Also, I own none of the artwork that you will see here.
