Time skip for six years b/c if I put Naru's time in the Underground learning under Toriel, it would be a boring chapter.

Sitting in the middle of a clearing watering some flowers was a sixteen-year-old Naru. The young woman's hair was cyan with a white ribbon tying the bottom of her hair back. Her green eyes had changed over the years, from a dull shade that looked closer to black, to the now forested shade that you would see in rainforests or dark emeralds. Naru wears a miko-like robe that is white and purple with the Delta Rune on the front lie her adopted mother. Naru's skin had taken a porcelain look over the years, but her signature whisker marks still stand out against her skin, proving that she has had contact with the Kyuubi's chakra in her past.

'Today seems like it will be a nice day although I worry due to Flowey's increased activity. I hope that if another child falls that damned weed doesn't get near them.' I still remembered my first meeting with the flower monster after falling into the underground and hoped that no one else got such a welcome. Humming under my breath, I recalled why mother always checks this area.

Flashback no Jutsu

"Mother, why do you take such good care of these flowers?" A twelve-year-old Naru asked Toriel.

"Well Naru, this is where the body of one of my children was buried. I had two children. Asriel, my son by blood, and Chara, my adopted daughter. Chara was a human who was bullied for her looks and actions. She eventually climbed the mountain for the same reason you did. When she had fallen, Asriel found her and brought the dear to me and my ex. Both of my children died to humanities cruelty. My ex-husband swore that any human who entered the Underground was to be killed. He has collected eight souls and still he refuses to acknowledge that a monster can pass through the Barrier with only one human soul. He also refuses to remember our history. You see Naru, the HOPES and DREAMS of every monster in the Underground can be substituted for one human soul and if my fool of a husband would realize that than we would already be interacting with the rest of the world." Toriel explained to her adopted child exactly how the Underground worked as well as pointed out all ASGORE'S flaws.

"You're right, mother. The king truly is an idiot." Naru understood where her mother was coming from and agreed with some of the statements Toriel would make. "If he had bothered to pay attention than this entire mess wouldn't have happened in the first place."

Smiling to herself as she remembered the rant hat followed that conversation, Naru looked up to see a child falling. Naru quickly used her chakra to jump and catch the child.

"Are you alright little one. That looked like quite the fall." The kid looked at me and signed

"Thank you for catching me. My name is Frisk. What's yours miss?"

"My name is Naru. I guess since mom isn't around, I should show you around the RUINS. C'mon." As Naru showed Frisk around, the child noticed how the monsters were respectful to the woman.

"Now, I am going to have a Froggit initiate battle with you. I want you to talk with it and the spare it."

Froggit approaches. It seems happy to be your opponent.

Froggit doesn't know what you said but it blushes anyways.

"Ribbit ribbit."

"Good job Frisk. Although I have never heard anyone flirt like you did. Any ways, you should familiarize yourself with the many puzzles found in the RUINS. It may end up being your saving grace." As Frisk looked around the room, Naru gave the Froggit a piece of monster candy. "You did well. Have a gift."

"Ribbit ribbit. (Thank you, young princess. Your generosity knows no bounds.)"

I am skipping the RUINS b/c those of you who know Undertale already know how the RUINS are. The only difference is Naru stays with you the entire time.

"Here we are. HOME sweet HOME." Frisk laughed at the woman they saw as a sister.

"Is this where you and Goat Mom live?"

"It is indeed, kiddo. Mom is probably making some pie, so let me show you to your room." As Naru walks in, Frisk notices a staircase in the middle of the room. They walked into the left hall and stopped in front of the first door.

{PoV Frisk}

"This is your room kiddo. See ya when mom is done cooking." With that said, Naru walked into the bedroom next to mine.

Walking into my room, I noticed that there were multiple children's shoes all lined up in a closet next to a couple of drawings. 'Did any other children besides Naru fall? That might be why Goat Mom doesn't like anyone leaving the RUINS.' Right as I finished that thought, I heard a door creaking behind me.

"Child are you in here? I brought some cinnamon butterscotch pie." The womanly voice was motherly and cautious, almost as if she were afraid of terrifying me.

"My name is Frisk. Naru told me a lot about you, Goat Mom." Goat Mom seemed to relax a little but also with held a deep resignation.

"You do not wish to stay in the RUINS, do you my child?" At my shake of the head, she seemed to smile a bit bitterly. "I will at least make you a kit to protect you in the UNDERGROUND. Naru seems to enjoy having a younger sibling and I would hate for her to lose the only child she has met. Please promise me you will be safe." I cross my heart to show that I was serious. I have never had an older sibling as caring as Naru and if anyone tried to hurt her they would have a E. Goat mom seemed happy that I promised her to stay safe.

Meanwhile In The Basement

"Knock Knock."

"Whose there?"

"Promise."

"Promise who?"

"I need you to promise me something." The feminine voice said cautiously. Sans instantly knew this was important.

"What do I need to promise?"

"That you will protect the young child that exits the RUINS."

"Wouldn't your mom prevent them from leaving?"

"She already knew that this one planned to leave and instead decided to make a kit to help them."

"I'll see what I can do, Naru."

"Thank you, Sans." With that both comedians left to do their respected jobs.
