Y/n was in a blank Au. 'Could-could I have made one?' She wondered as she looks around. She grabs the toy and focused onto it putting 10% of her soul in their.

Once again, it came back to life- almost a real one. They meowed and purred on her leg. She lets out a small smile and sat next to the cat.

"Well.. I can still make p/n alive." She mutters as she pets p/n making them purr.

"Now, what should I do.."

'If I am correct.. I can create my own Au by giving a small portion of my soul like I did to p/n but, does it still need a vessel like a toy? Or I can make one easily with only pure imagination? There's only one way to find out.' She closed her eyes and imagined a human —all she can think was the first human who was murdered by gaster. 'A human boy who was filled with bravery.' She thought closing her eyes tightly- trying so hard to make a human. P/n starts to hiss towards to something. Y/n opened her eyes slowly and saw a human boy- the same as she thought in her imagination. She was awestruck on what she did, it turned into a huge smile. She was happy and proud that she made a first creation. Though, 8% of her soul was taken to make one.

'I did it!' She stood up —wobbling slightly.

"This is my own world.." she says as she imagined the world filled with lush green grasses and different kinds of beautiful flowers. She made trees, oceans, lakes, and different kinds of landscapes. She was happy that she made a place so beautiful in such a short time. She lays on the grass and smiled.

"Now all I need are humans and monsters— and of course, I need to forget everything I've experience with him." Y/n says as she looks up.

"I won't be called as experiment 0.3 anymore. I'll be called as y/n —just as how Sans preferred calling me." She yawns from the tiredness.

"Good night p/n." She mutters as she goes closer to them. The cat meows and curls up beside her.

—A Few weeks passed—

"P/n, what do you think of this Au?" She says looking at the Au, Underswap. She was wearing An all black clothes- she was covering her face using a mask. The cat only meowed.

"Hm, I don't know what you mean but, I'm guessing that's a yes—" blue strings suddenly wraps around her arms and by the stomach.

"Now what's an odd human doing in the Underswap Au?" The cat started to hiss at a skeleton.

"A sans? Who are you? You don't seem to look like the sans I know." She says looking at him.

"A fearless one eh? Well anyway, names Error. What 'bout you?"

"M/n."

"A'ight then, m/n. What brings you here in the Au?"

"Nothing in particular. I was just looking at how other Au's work." She spoke. The cat suddenly ran towards Error getting ready to bite him- Error avoids the attack and aims two sharp bones towards to p/n.

"P/n!"

"Tsk, Tsk, Tsk. You should really train your pet to stop attacking a stranger." He spoke grinning.

"You people don't have manners and it's very annoying to have those kinds of things don't ya think?"

"What kind of tricks are you playing error."

"Oh I'm not playing any tricks." He spoke as the strings loosen, y/n falls on the ground.

"I was only presenting how powerful I am if you ever dealt with me." He says as he creates a glitchy portal, "also, if I were you. Ya can't just go on around different Au's merrily, there are also some Au's who kills others." He adds as he enters a portal. The portal was gone just as he enters.

P/n meows weakly.

"P/n!" She ran towards them and picked them up gently.
"I'm sorry. I couldn't defend you." She spoke as she teleports back to their Au.

Recently, she made more improvements in her Au. She made both Monsters and Humans be at peace in each other and made a person who has the soul of determination and also a person who has the soul of hope. She made toriel and Asgore- with asriel too of course. She met a toriel in the ReaperTale Au and made one. Y/n also made her own family and friends as a way for her new self to feel like she belonged to. The place is also modernized like every Place she saw in each Au.

She was in the hospital now looking for a certain monster.

"Toriel!" The goat lady turns around.

"Yes?"

"Toriel please help me recover P/n." Y/n says as she holds back a few tears.

"I'll try my best on that my child."

"Thank you!" She hugs her only using her one arm since the other arm is occupied by an injured p/n.

"No problem my child. Now, may I?" She gave p/n to toriel. In her Au, Toriel was a nurse who has a healing ability like the one in ReaperTale.

Y/n sat by the chairs waiting for p/n.

"Maybe it would be best for them to stay here." A sudden headache comes making her train from the pain. She's forgetting almost everything slowly now and she knew that.

She made everything in this Au so, she doesn't have that much strength or any strong abilities now that she only has 8% soul she has. Y/n planned everything- she made Chara as the bearer of Determination so they were assigned to RESET the world once she told them so. Though, the only thing that worries her was p/n. She knew that p/n won't accept that they will be forgotten completely.

Her body suddenly feels heavy, and her eyes are also getting droopy. She lays on the rows of chairs and let her rest her body.

—In her Dream—

She wakes up in a bright, open garden, with a few trees. Y/n was laying under the tree of feelings. She sat up and looks around and saw a skeleton monster with a purple sleeve clothes and a gold crown with a crescent shape in the middle of his crown. H e was quietly reading a book.

"Nightmare?" The monster was startled and looks at her direction.
"H-hello y/n."
"Hey! How are you and where's your brother?" A faint tint of purple forms on his cheeks and looks away.
"I-I'm doing alright, thanks for asking. And uhm.. my brother is handling other's dream."
"Oh.. well, I'm glad."
"What do you mean by that?"
"I mean, I'm glad that you're the one with me in my dream." Nightmare looks at y/n surprise and bafflement was shown on his face.
"R-really?" She giggles.
"Of course! Why are you so  surprised about that?"
"Well it's just that, no one really said that to me in my life- other than dream I guess."
"Then, you can say that I'm your first Admirer- or fan if you prefer." She says with a chuckle.

Nightmare smiled. he came forward and gave her a slight loose hug. "Thank you y/n."  She hugs back.
"Thank you too for always making my day, Nightmare."

I'm sorry for the late update ;-;
I tried my best to follow the schedule so I wouldn't mess it all up-- also, some of the parts in this chapter oddly reminded me of BNHA(Know that I'm just new to the fandom alright XD)

Though, on the next chapter would be about outside y/n's mind or memory. Meaning we'll know what's happening in the present.I'm quite excited for that-
btw, I might make an Error x Reader After this but the story plot won't be connected in this-- I mean I kinda want an alternate end where the reader ends up to error but nah XD
I kinda completely forgot almost 50% of this plot(tbh I don't think there's an actual or a concrete plot on the first few chapters- I just copied some of the plots that I've read in the Nightmare x reader books XD)

Anyway, thank ya'll for reading this book- I'm very happy that we've reached 41k reads! I'm clearly surprised that I managed to make one of my books had a lot of people reading my book! Again, Thanks for the 41k reads and also for supporting this book for 3 years- Ya'll have been very patient to my updates and I'm glad.
