It has been about a week...since Dust Sans has returned to the Underground itself. And needless to say, things have been very interesting for Sans and the people he had rescued.

Thanks to Asgore, at Sans' request, he was able to make a new area in the Underground, with Sans having collected enough Mobians to save them from extinction. Horror also went around and found so many humans by the same amount of Mobians that Dust had found. Thanks to that, the 2 other species are saved. Although...the monsters are a little bit hesitant to get along, due to them remembering the Bloodbath of Mobius, with the feeling being mutual to the humans from the surface. But the King of the Monsters had encouraged them to give it time, as all 3 of them are facing a very common threat, and the 3 species must stand together in order to defend against those horrifying creatures.

Cream and Vanilla are able to get a house that is identical to the house that they had back in the surface, except that the house is located in Snowdin, which is here Sans lives in.

She chose to be in Snowdin, because since Sans saved her life, she feels very comfortable about her, almost like he is there to always protect her. And of course, Vanilla is extremely thankful that Sans protected her daughter from the demons. Sans doesn't seem to mind, as he actually had taken liking of the kid.

Blaze and Shadow are living in their own separate houses, although Blaze lives in hotlands, due to the heat that is present. And Shadow...he never shows his house, due to being a secretive guy of privacy. But Sans leaves him he to do his own stuff, since he really doesn't care about what that hedgehog does.

Tangle, Whisper, and Jewel are living in Waterfall, and the trio are living next to Undyne, who they now have a good relationship with, due to being immensely brave. And they been train with each other in order to make each other more stronger.

Horror Sans, Papyrus, Flowey, and Aliza are at a house of their own. It resembles Dust's house, but in a little bit more of a creepier fashion. Aliza still comes out of the house, and has grown to like the monsters of this Mobius, due to the fact that they are a bit more friendlier.

Amy Rose had immense difficulty adjusting, due to how she is a demon, and the Mobians seemed to be very weary of her very presence. But eventually, with some help, she was able to grow comfortable, and even sully, the whole underground feels comfortable to have a friendly demon. Speaking of Killer, Amy and him are living with the Dust Skeleton Brothers, because Papyrus has a healing influence on his mind. Thanks to that, he does not need to feel like Killer anymore, and in fact, can now suppress Killer longer.

As for Rouge...well...

Inside of Sans' own room...

"Mmmmmmmm..."

Sans has been feeling strange...due to a sudden increase in weight suddenly appearing. Sans tried to stand up, but than...he felt arms wrapping around his body. He than opens his eyes, and sees that these arms...belonged to Rouge the Bat herself. That's right. Rouge decided to live inside of Sans' house. And clearly...Sans has no idea why she decided to go inside of his house. But it looks as though that she has taken quite a liking of the Skeleton. Even Sans has nothing to say about this right now. Sans tries to move, but Rouge ended up wrapping her legs around Sans, and wrapped her arms around his neck. Sans was a bit surprised at this action, and Rouge ended up putting her head over Sans' shoulder, as her ears than twitched on his cheek. Sans wanted to do something about it, but Sans is simply a little lazy.

Sans just simply shrugged, and he just went to sleep, as he lets Rouge sleep next to him. Rouge continued to hug Sans, and Sans felt...something soft...on his chest. He doesn't know why...but he know that what he is feel...it is like a pillow. But Sans...he does not have another one. What is it that is touching him?

As he looks at Rouge...

SLAM!!

"NYEH!! SANS!!! WHY ARE YOU STILL IN BED, YOU LAZYBONES??!!!!"

This made Sans leap in the air for a bit, and looked to see that his brother was responsible for the noise he made.

"papyrus...you do know rouge is sleeping, right?"

Papyrus looks and sees Rouge is in the room with Sans, and true to Sans' words, she is sleeping her head off, and is still sleeping amazingly, in spite of how loud Papyrus was acting for before. Papyrus covers his mouth, as he than sees Rouge began to move and hug Sans a bit more tighter. He than looks up and spoke out.

"she still cannot stop thinking about the horrific stuff that had happened to her back at the surface. mind letting her get the rest that she needs right now?"

Papyrus nodded, as he spoke out.

"ABSOLUTELY, BROTHER!"

He than closed the door, and thankfully, does not make a sound. Sans sighed...as he clearly had no idea what to do with his brother.

An Hour Later...

"rouge? are you all dressed up yet?"

Sans spoke out to Rouge, who is getting dressed up inside of his room.

"Just one more minute, hon."

Sans sighed, as he clearly wished that Rouge would stop calling him that. But, what are you going to do about it?

Sans waited outside for a minute, before Rouge finally spoke out.

"Alright. I'm done being dressed. You can come back inside now."

Sans sighed, as he than got up from the ground, went to the door, and opened to see that Rouge is in fact dressed...with a seductive pose.

Sans blushed a bit, as he saw him the way Rouge was posing to him. But luckily, he is wearing his hood, and because of this, Sans' face is completely covered up.

"Well...besides that. Anyways, let's see how the others are holding up at adjusting to the Underground. Shall we, Rouge?"

Rouge smiled, as she spoke out.

"I couldn't agree more."

Sans smiled, as he grabs her by the shoulder, and they both teleport outside of the house. The snow began to crunch underneath their feet, as they landed onto it.

They than looked around, and saw that everyone is doing their everyday thing, except that they are snow greeting the Mobians that made the decision to live inside of Snowdin. Sans smiled a bit, as his 2 red eyes glowed a little bit of seeing the 2 species get along. Aliza, she is the only human that lives in Snowdin, and yet, she gets along with everyone. Sans sighed, as he than spoke out.

"Guess it'll take a long time for all 3 of the races on New Home to get along. The ones is Snowdin get along swimmingly well."

Rouge than spoke out.

"Well...why don't we see how the others are doing?"

Sans looks and nodded with a smile on his face. But as they are preparing to go...

"Mr. Sans!"

Sans looks to see that Cream is flying towards him and before Sans realizes what was about to happen, Cream rammed and hugged into his chest. Sans didn't budge, and hugged Cream back, clearly feeling a little bit happy that she's okay.

"heya, kiddo. seeing you're still your usual self as always."

Sans spoke out, as he began to rub her head, and Cream smiled in content, at the feeling of her own head being rubbed by Sans. Cream than looks up at Sans,

"If you don't mind telling me, where are you going, Mr. Sans?"

Sans spoke out to Cream.

"i'm gonna go see how the others are doing with how they're getting used to this, living in the underground, i mean. after all...it is a very new experience for them."

Cream nodded her head.

"I guess that makes sense. After all...me and momma had trouble with getting used to this as well, Mr. Sans."

Sans nodded, before speaking.

"understandable...as this is a very new experience for everyone to witness."

Cream and her mother, Vanilla, initially felt uneasy of being inside of the Underground, where the monsters reside in. But after a little bit, and seeing that they are friendly, they got used to the new place that they are living in, and soon, they start to act a lot more like neighbors, almost like they are still at the surface world again. Sans than puts Cream down.

"well, kiddo. i've gotta see how the others are doing. also...tell your mother i said high, capiche?"

Cream nodded with a smile.

"I will."

Sans smiled, before Rouge than picks him up from the ground, and took flight, as they both go to the Waterfalls, in order to see how Tangle and her other 2 friends are doing there.

They continue to fly, until they finally reached the area they've been wanting to go to, the Waterfalls.

[There should be a GIF or video here. Update the app now to see it.]

Waterfalls, is very beautiful, and the beauty does not cease to impress Rouge, as the Echo Flowers glowed in the dark, and they illuminated the entire place.

"Wow, this place...this is still very beautiful. Must be a very interesting experience to hear those flowers."

Rouge spoke out, as she clearly has never seen them in action on her life. Sans smiled, as clearly, he never showed Rouge of what they can do. It would be an interesting thing to see what they are capable of doing.

As they began to fly away, a voice spoke out to them.

"Sans, Rouge!! Over there!!"

Sans and Rouge turned to see Tangle, Whisper, and Jewel with Undyne, who is now out of her armor.

"Hey, punks!! Nice to see ya!!"

Sans grinned a bit more, as they than landed on the ground, with Rouge putting Sans down first.

"Heya, guys. Nice to see ya. You 3 able to get used to this?"

Tangle nodded, as she spoke out.

"Yep, we are. It was a little strange, but Undyne sure is very friendly, even when she's a little bit rough."

Undyne smirked, as she spoke out.

"Well...that is what I always am, Tangle! Besides, you are the same thing!"

Tangle smirked, as both her and Undyne smacked hands together, and Sans smiled.

"Well...it's nice to see that you girls are getting used to living in the Underground, even if it is a very weird experience for you 3."

Tangle shrugged, as she spoke out.

"Well...at least we manage to get used to it. Besides...having a training partner with the captain of the Royal guard just makes my day."

Undyne smiled, as she seems to like the fact that Tangle appreciates her. Rouge the spoke out.

"Well...it seems like we have some very nice areas to go to, especially the Waterfalls."

Sans smiled, as he closed his eyes. Than, Rouge picks up some voices, and turns to see that...it is coming from the Echo Flowers. She looked interested in it, while everyone just watched as they heard the voices from the Echo Flowers.

"These flowers do give m the creeps. Having voices repeated inside of them, it is a little bit terrifying for me."

Jewel spoke out, as Sans simply shrugged.

"ehh...it is what it is in the underground."

The skeleton spoke out, as Tangle spoke out.

"I think it's cool that they do that."

Whisper nodded a bit, admitting that this is very interesting to see these sorts of things. Sans looks around, and spoke out.

"well...as much as I like to converse with ya, but i'm gonna go to hotlands to see how the others are doing. Namely, blaze and silver, since they're living here."

Whisper spoke out.

"Understandable, considering what they have been through."

Tangle smiled, and spoke out.

"Oh, and Sans..."

Sans looks at Tangle, and before he knew it, he is suddenly wrapped in her tail, and he began to spin around, before being hugged by Tangle, catching him by surprise.

"Thanks for helping us back at the surface. Weren't sure what we would do without you helping."

Tangle spoke out to Sans, who is surprised, but than hugged back, and spoke out.

"ehh...don't mention it. besides, you should thank asgore for letting you stay in the underground."

Tangle smiled wider, as she spoke out.

"Still, thanks."

Both Sans and Tangle separated, as Rouge flied next to him, and spoke out to them.

"welp, see ya later."

Rouge picks Sans up, and flies, as they waved goodbye at the 2, as Rouge and Sans go where Blaze and Silver are residing in. Rouge smiled, as they than go to the route of where Hotlands is at, but as they did...they went to a rainy section of Waterfalls, and they both got wet. But that didn't matter to Rouge, as being with Sans didn't make it a bother for her when flying.

But as they continued on, they than saw something in the distance. It was New Home.

Rouge stopped for a bit, and looked at the city in the distance. It was very large, enough to house about a million Mobians inside of it.

She looked, as the rain dropped down on top of her head. Her eyes looked in awe, as she sees the city off into the distance. In spite of how dark the area she is in is, it's still clearly seen.

Sans stood in the rain, as he spoke out.

"Interested in New Home?"

Rouge nodded her head, as she went next to the Bat Mobian that is staring at the city in awe of its appearance. Sans made a genuine smile, as he spoke.

"Hey, we'll go to New Home last, alright. For now, let's go to Hotlands."

Rouge turned and nodded her head.

"Right."

Rouge than picks up Sans again, and they all go out to the Entrance of Hotland. But it went so fast that Sans has no idea how long it took for them to reach the entrance. When they did, they finally have arrived. And needless to say, they are greeted to a sight that they are not expecting.

[There should be a GIF or video here. Update the app now to see it.]

Now they are in Hotlands, and needless to say, it really lives up to its name. There is a river of lava below the mechanisms and the rock that the metal is suspending above it.

"Okay, this does actually looks bit creepy. How does anyone even live in this area?"

Rouge spoke out, as Sans spoke back.

"Fire monsters, but there are others that do are not fire-based, yet still live here. So it really doesn't matter."

Rouge sighed, as she puts her hand in her face.

As they landed on the ground, another male voice spoke out.

"Hey, guys! Over here!"

The 2 turned to see Silver and Blaze are inside of Hotlands.

"heya. see you're doin fine from being in the underground."

Sans spoke out to both Blaze and Silver, as Blaze spoke out.

"Of course we are okay, Sans, thanks to you."

Sans smiled a bit wider, as Silver spoke out.

"Don't know how the future is going to change with this happening, but it is worth the shot to try and bring them to the Underground. I'm just hoping it will really help."

Rouge spoke out to Silver.

"I'm pretty sure it will, Silver. They're safe inside of Ebott."

Silver looks down, as he than spoke out.

"I hope so."

Sans sighed, as he shrugged.

"By the way, the both of you seen Shadow anywhere?"

Blaze looks and spoke out.

"Shadow? We don't know where he is. But he's fine, as he is in some part of the Underground."

Sans spoke out.

"Of course."

Rouge than looks at Blaze, as she than spoke out.

"And the Denizens of your world, how are they doing?"

Blaze turns to Rouge and spoke out.

"They are doing very well, Rouge. It will take them a long time for them to get used to, but they will pull through and get used to this. After all, the joke we live in is no longer hospitable for them, due to what that demon had done to it, as well as the citizens that were caught by him."

Rouge nodded, as Sans spoke out.

"well, i hope that they like their new place to live in, even though...it isn't like their home, as well as the home you live in."

Blaze nodded, as she than spoke out.

"One more thing you should know...the Chaos Emeralds, Sol Emeralds, and the Master Emerald, they are now used to increase the Core's Power, with Mecha Sonic and E-123 Omega guarding them. This is so it can increase the magic covering the entire Mountain of Ebott to protect us against the demons, as well as making sure that the concealment becomes something else to the Demons, should some try to entire the Mountain itself."

Sans nodded, as he spoke out.

"Understood."

Sans than looks behind him, and spoke out.

"Well...me and Rouge are gonna go to New Home, to see how the Mobians and the Humans are doing, I'd you don't mind the both of us leaving."

Blaze shook her head, as she than spoke out.

"Not at all."

Sans smiled, as he puts a hand on Rouge, and used his ability to teleport to the lady location they wanted to be in.

[There should be a GIF or video here. Update the app now to see it.]

Now they are in New Home, and needless to say, this whole place is filled with Monsters everywhere. There is simply no end to the amount of Monsters in the area. But that is simply one part of New Home. In another part, are the Mobians, both from Sonic's World and Blaze's world.

Rouge began the look around and see the Monsters, Mobians, and Humans in New Home, and Sans does the same.

"You seem to be enjoying yourself."

A voice spoke out, making Sans turn around, only to see Shadow from behind.

Shadow smiled, as Sans spoke out.

"well...you could say that. i'm surprised to see you here, even though you are a loner at best."

Shadow spoke out.

"Normally...I would, but even I am impressed at how you can live like this, especially in a mountain."

Sans spoke out.

"okay. but mind telling me why you are speaking to me now?"

Shadow simply spoke out.

"Maybe because I want to?"

Sans spoke out.

"Sure, why not."

Suddenly, he felt someone grab his hand, and before he knew it, he is suddenly raised above the air fast, and looks to see Rouge being the one that is grabbing onto him. Rouge looks down with a pleasurable smile on her face, as she than let's go of Sans for a bit, before grabbing him by the sides of the torso. Before Sans realizes what was about to happen, Rouge suddenly kissed him.

"ghhhhhhhhh..."

Sans was caught by surprise, as Rouge kissed Sans at the mouth, even though he does not have lips of any kind. But it seems that you don't need lips to kiss. Sans tries to push her off gently, but Rouge held him on extremely tightly, and Sans has no idea how to escape her grasp. Teleporting is not going to work for him, as he needs to be separated from Rouge. But since he is not, he's stuck until Rouge is done kissing at his mouth.

Sans blushed purple, and because of being in a place that has monsters, his face is now being shown. Clearly, Rouge wanted to make him to do this face, as she wants to see Sans blush.

With Exetior, Sark, and Pervision...

The 3 demonic hedgehogs are sitting someplace to be in for a meeting of sorts. They are conversing with each other, as Pervision spoke out to Exetior.

"Master Exetior...I manage to collect the Red Liquid that seems to come from the Skeletons that we have been fighting. It is...interesting...to say the least."

Exetior looks at Pervision, and spoke out to him, interested.

"What is this liquid than?"

Pervision looks at Exetior with his one eye, and spoke out to him.

"I have examined as much as I can...and it is filled with properties that I have never seen before. It is tied to the trait called, Determination, and it seems to be capable of effecting time itself."

Exetior looks up at Pervision, as he spoke out.

"Effect time itself? How can you be so certain about this one, Pervision."

Pervision than spoke out.

"I have looked into the liquid, and see that a memory of a human that had this power. Apparently, they have the power to go back in time, and choose a route to either spare the monsters and free them, or to kill them. Sans, he is the only one that is capable of remembering them, and both Dust and Killer, they gained their own determination through the killing of their own kind, although Dust destroyed that power when he no longer has any use for it. But Killer...maintained it."

Exetior held his hands, as he spoke out.

"We need to find a way to get them, but how do we do that? They live in a place that we are unable to locate."

Sark thanks began to laugh, as he spoke out.

"It will be no problem, Exetior...for I have manage to get someone that could be of help for us."

Exetior looks at Sark, and spoke out.

"And what would that be?"

Sark than snapped his fingers, and suddenly...another Sans appeared from behind Sark, and he does not look very good."

"What is that?"

Exetior spoke out, as Sark spoke out.

"I manage to find a Sans that we can use for us to kill. One where he is devoid of Love and Compassion, and instead, is filled with nothing more than violence and extreme sadism. And since he is a Sans powerful enough to combat against the other 3, we might as well use him to combat against those 3."

Exetior than looks down for a little bit, before speaking out.

"Just make sure he brings them to me alive, Sark. Do you understand it?"

Sark nodded with a smile.

"I do. Hey, Insanity!"

Insanity looks at Sark, as his mouth twitched in his maddening grin.

"Try and find those 3 lookalikes of you!"

He spoke out, as he conjured the appearances of Killer, Dust, and Horror in the air, as Insanity spoke out to Sark in a sincere, maddening tone to the one that had summoned him from his Mobius.

"It will be done."
