Abyss and his friends, they are able to get back to where Yasaka is just in time, as Abyss was able to get the CELL Core inside of the syringe that Yasaka had brought along with her. However, since Abyss has modest, Ravel had to do the honors and inject the CELL Core into Yasaka's soul. And after a little bit of time, the CELL Core began to take its effect on the Kyuubi's soul and body, making her more stronger then before, and since Abyss already powerful her with the Energy Cell, it was able to be completed into her body much more faster than before. However, Abyss knows that this thing will not last for long. So, he was able to get a communication's device, and was able to speak to Alphys and told her of the situation. Alphys could not believe what she was hearing and what Abyss revealed, of how their world is still existing with people, but now has became an undead world. Regardless of the shock, she went to work on making a machine, and was able to make a dome that protected all of Kyoto. And this is where Abyss is at right now.

"Entry Log 4:

I didn't expect visiting my AU again to be this bad. The world I once knew no longer exists, it's now something I never could have dreamed of. I can't figure out how the Fallen Cells have managed to mutate further. Normally they die off within hours, unless they find a way to stay alive longer, but these creatures have the intelligence of wild animals. They know how to hunt, kill, survive. My best theory is they've found a way to survive in this environment by consuming flesh, but there are no more living beings left in my AU. Unless something or someone is deliberately feeding them? Or maybe, they've managed to hunt in another AU undetected? ...I hope I am wrong. I have nicknamed these new mutated cells 'DEAD CELLS.'

The next day, Alphys felt ill. She said she was burnt out and had a headache. Normally CELL hosts are immune to sickness and disease. Perhaps she's pushing herself too hard? For safety measures, Alphys is the only one who can access the teleport machine. So we have to wait until Alphys gets better. In the meantime..... I was practicing teleporting to different AUs without the machine.

My first test was to teleport to the classic Undertale
world. No problems there. But when I tried returning to Outertale, I ended up somewhere else. Everything was dark, but then I saw CONTINUE and RESET appear above me. I encountered a version of Classic Sans called Geno, who's badly injure but still makes puns. There was a Frisk there, too. We conversed for a while, until we talked about Papyrus. At first, I was hesitant to talk about my brother's situation.... but I hoped Geno could give me some advice about how to help him recover... I regret it. It was pretty intense, but we both managed to calm down. We managed to apologize with no hard feelings. It was time for me to say goodbye to Geno and Frisk, and return home. I made it back to Outertale safely. I was exhausted after teleporting to several AUs in a single day. Alphys and Mettaton didn't realize I was gone for a few hours.

A few days later while in another AU, I took a break in a nice spot beneath a tree, and was peacefully reading my book, until an unexpected visitor greeted me. He calls himself Template. Apparently he is a version of Error that has decided to be a protect like the one that is named Ink.

Another day, another unexpected encounter with another Sans traveller. This one is. maybe the grumpiest Sans I've ever met. And here I thought I was grumpy.

And speaking of Ink, another day, I met the infamous guardian of the multiverse himself, Ink. He is a very odd person to be with, but I felt something wrong. I could not sense anything I side of him, not even a place where his soul should be at. He may be a protector, but I have a very bad feeling about this guy. He may seem funny at first, but I am going to need to keep my distance and make sure that Ink is not trying to do something.

Next week, we returned to work. Today was a
pretty interesting day. This AU's ambience was...
blue and grey. Feels depressing, if you ask me.

Alphys and I headed to the lab to get minerals and medicine for my bro. When she met this AU's Alphys, well, she noticed the difference and started asking us questions. Alphys distracted her counterpart with lots of nerdy stuff and anime. It was successful, and everything turned out okay.

The next day, to the next AU. It was Alphys and Mettaton's turn to go to the lab for materials and equipment. When I was about to make dinner, I caught a little thief. The intruder looked like a tiny
Underfell Sans, who snuck into the kitchen and tried to steal a bottle of mustard. This small fry thought no one was home, but him trying to steal food from us was a big mistake. I wasn't able to catch him and
he escaped with the bottle. It was almost empty, anyways, so it doesn't matter He can have it. And besides, I teleported him back to whence he had came.

One month has passed since the incident in my
undead AU. I wonder if Parasite!tale sans is doing okay."

Abyss sighed, as he has finished his most recent entry log, a little bit exhausted. Clearly, he did not think that he was going to get exhausted. He never felt so stressed on his life. Abyss held his head, as he than stood up, as he looked around. It's been a month since he is now back in his own AU. Inside of the safe dome that Abyss is inside of right now, which Alphys has made with a machine.

After Alphys had made that machine, Yasaka finally got a huge break from doing all of this. She was so worked up from having to do this for so long that she thought that she was going to collapse and not come back up again. But thankfully, now that Alphys has made this machine, she is now able to give Yasaka the break the she deserves.

The House has been teleported back to an empty spot in Kyoto, and so far, everyone is okay living here, especially since the force field is indestructible, and cannot be broken. Not even the Dead Cells outside are able to break the entire done. So that is a relief. And thanks to this, Kunou is able to have some fun with Yasaka again after what must have been so long. However, this is one thing that bothered Abyss, like a lot, with when it involves Kunou. After Abyss has saved Yasaka from this terrible fate, Kunou was very happy and thankful of what Abyss had done for her. Atla, not liking that Kunou was getting to close to Abyss, tries to defend Abyss from Kunou, as to not have Kunou get close to him. But Kunou, in a desperate attempt to be close to Abyss, had bitten Abyss in the leg, for her territory.

And needless to say, the situation got very messy for Abyss, as he had to try and prevent the 2 of them in making sure that they all do not fight over each other. And since Kunou had bitten him in the leg, there was nothing that can be done, and thus, Atla had to let Kunou be, since she had marked her territory. However, this did not stop Atla from raising her own had and biting Abyss in the neck, in order to mark her territory.

Lucidia and Paper Crane had to go, and Abyss have Paper Crane a single Energy Cell in order to fill him up, and he said goodbye, but not before calling him, little fluffy Sans, much to his ire. Lucidia needs to leave as well, but promises to come back to meet you with Abyss and see how his progress is doing.

Ganyu was exploring the place just fine, as she wanted to see what it is all like in Kyoto. Abyss did not seem to mind, as he allows her to do it. Ravel and Kunou began to walk side by side and hang out a lot, while Atla simply went along with Abyss.  Of course, Kunou also gets to hang out with Abyss whenever she has the chance to do it. The other, such as the Shinobi, Eri, and Nejire, are inside of the house, and refuse to come out, until they know that their friends are alive. Although, for Eri, he thinks they the others keep them around, simply because they enjoy her presence.

Abyss sighed, as he than puts his Entry Log down and submits it. He than stood up, and turned around d to see the DNA Strands all over the floor and coming out from his back. He than looks around and saw that he needs to go outside so that he can gain some fresh air. And so, Abyss than puts on his jacket, and his scarves manifested beneath the fluffy hood. He does not know how much that he can take it, but he needs too see however is doing, ever since he has disappeared from his AU, after all, he wants to know how everyone now is feeling. And Atla, being her usual self, held onto Abyss' hand, as starts to walk along with Abyss, as she refuses to let him go. Of course, Abyss realized that, he got Kunou's age wrong. She is not 12, she is a year old. She is a 13 year old Kyuubi. So that fact that he had gotten her age wrong is a tiny bit frustrating for Abyss, due to the fact that he is not supposed or act like this. And of course, she is at the same age as Atla, who is also likely to be at the age of 13, and both are very possessive of Abyss himself. But since Kunou is with her mother, Abyss simply walked around town.

Abyss looked and observe everyone's facial feature. While they do look more relived, due to the fact that they have a much more permanent protection than what Yasaka had done, they are still scared about the stuff that is happening outside. They are lucky that Abyss had called Alphys, who was able to set up a dome of this size, but it still does not change the fact how much the Dead Cells outside scare them. Because of this, they did all they can to make themselves feel comfortable.

As Abyss walked around, he hears a voice form across the street.

"Sans..."

Abyss stopped, as he actually heard that voice before, and it sounded very familiar to him. He than turned around to see who it is that had spoke out to him, and sure enough, it is someone that he knows about, it is from when he was still in Union Academy, which had outright tormented him.

"...Rossweisse."

Abyss said, as Rossweisse was stunned to see Abyss, as she did not expect him to come to Kyoto, as Rossweiss was stunned to see Abyss, as she than began to speak out to him.

"Sans...is that...is it really you, Sans?"

Than, tears began to flow out of her eyes, as she teleported to Abyss, and before Abyss can do anything, she hugs him right. Although normally, he hates Union Academy, he does have some friends here, and people that are rather affectionate to him. And Rossweisse, she is one of such people affectionate to him.

She hugged him tightly, and Abyss could not simply reject it. So all he did was lean against Rossweisse's neck. And Rossweisse felt very happy that this is in fact Abyss, due to the fact that she is able to feel his rather familiar body.

She than looked at Abyss, and saw that he has grown a lot more taller, as she than spoke out to Abyss.

"Wow, you've grown taller, and it has only been a year since we had last seen each other. How are you...you..."

Abyss sighed, as he than spoke out.

"It...it is gonna be a very long story, so, do you think we can sit down someplace for us to talk about this topic?"

Rossweisse nodded her head, as she saw a bench,
And Rossweiss sat on it, as Abyss does the same, and he began to explain what had happened, and the fact that time had worked differently whenever he had left. When he finished, Rossweisse spoke out.

"This is some story. And now, here you are right now, you are all grown up, already an 18 year old man, and already a handsome person with a newer tall height."

This made Abyss embarrassed a little bit, as he than shook his head in order to get rid of the blush that is coming onto his face. Atla was not happy, as she hugged Abyss on the arm tighter, as Rossweisse than spoke out to Abyss.

"But...seriously, it is still amazing that, you had went to different universes, and met alternate versions of you. It just have been a frightening experience for you, isn't it?"

Abyss nodded, as he than spoke out.

"Yeah, that, and the fact that time in different AUs is changing as well. I went to an AU called Kintale for simply hours. But for the house that Alphys and Mettaton and Papyrus lived in, they thought that I was dead, and I was simply gone for 2 years in both their experiences. I had no idea how this happened."

Rossweisse nodded, as Abyss than spoke out.

"And also, there is also some answers that I would like to know. When the entire situation first happened, Ravel said thar she cannot teleport for some reason to the Underworld. What happened?"

Rossweisse was afraid he would say that, but she obliques and answers Abyss' question.

"Apparently, when all of those things popped up, and began to attack and consume people, the red entities from outside. The Underworld and Heaven tried to put them down. But because of how they simply multiplied and simply split apart into more and more entities, it instead kept on getting worse and worse. Rias Gremory and Sirzechs Lucifer, they held the longest, due to the fact that their Power of Destruction was enough to put a bunch of them down, but because there are so many, and the fact that they can risk the entities running loose in the Underworld or Heaven, they decided that it is best to lock themselves away. Rias and the rest of her peerage, as well as some of their friends, such as Irina, Kuroka, and the Sitri Peerage, retreated to the Underworld, and the Angels decided to stay in Heaven, as too not let the Infected inside of them, for then can risk breaching the Holy System. And to make sure that they do not get inside, they made special barriers to prevent anyone infected in being able to teleport into both realms. Me, however, I decided to stay behind and made sure that the humans or any survivors are able to get inside of this place, this one single sanctuary that no infected could breach."

Abyss looked stunned at this, but he looked down and sighed. Obviously, Rossweisse had told the reasons as to why it is not happening, and as much as he wants to curse at the 2 species, they seem to have good reasons. Rossweisse than stood up.

"Well, it is nice to see you, Sans. Let's meet again sometime, okay?"

Abyss looked at Rossweisse and nodded, as Rossweisse bent down and kissed Abyss on the cheek, as Abyss blushed, and Rossweisse teleported away. Abyss shook his head and Atla felt a little bit frustrated, as Abyss than carried Atla and landed onto a building, as he looked at the surrounding area that's before him.

But as Abyss looked at the view before him, another familiar voice spoke out.

"No way...Sans?!"

Abyss jumped and turned around to see who it is.

"Sans!!!"

Asuka shouted, as she leapt down along with the rest of Team Hanzo, as Abyss ran up to them, and hugged them all tightly. He is so happy that his old friends are alright. Abyss is happy, as he spoke out.

"Nice to see you all again, Team Hanzo. I thought you guys had died!"

Hanzo shook their head, as Yagyū spoke out.

"We did not die. And the Crimson Squad is kind of traumatized with all of this, but still fight in this city. And as for the rest of Yumi's team..."

Than, a presence was felt behind Abyss, and he turned to see 2 people that he did not expect to see. And it is also people that he had thought had died in the middle of this crisis, when I'm reality, they both had been alive after all of this time.

"Shiki, Murakumo, you girls are okay!!"

Abyss shouted, as they are stunned and happy to see that Abyss is alive.

"Sans! You're alive!!"

Murakumo ran up and hugged Abyss tightly, as Abyss struggled to breath, due to where his head is inside of. But he felt happy to see Murakumo again, as Shiki spoke out.

"Oh my, it seems that you are alive as well, handsome. How is my favorite Lawn Gnome?"

This made Abyss annoyed, but he still spoke a little pleasantly.

"I'm doing fine. Yumi and the other members of your team are doing fine themselves.

This caught their attention, as Murakumo spoke out.

"Yumi, Minori, and Yozakura are alive?!"

Abyss nodded, as he spoke out.

"Yeah, they're even at my house."

Murakumo and Shiki, without hesitation, jumped and leapt as fast as they can, and they know what Abyss' house looks like, as Asuka spoke out.

"It is good to see you again, Sans. But...where's Papyrus? Is he okay?"

When Papyrus was mentioned, Abyss looked sad, as he than spoke out.

"Papyrus...he...he is alive...but...he is in a coma. He lost his limbs and a top right part of his head, as well as losing an eye. Right now, he is kept inside of a capsule at my house, so he can remain stable enough, until me and the others are able to help heal him."

This made Team Hanzo stunned. And before Abyss can say more, they leapt to go and find Papyrus, in order to see what he looks like. But Abyss can only bet that their reaction will be of shock and disbelief, just like Abyss had those when he saw Papyrus' condition.

As Abyss looked down, Atla, sensing the distress in Abyss' mind, gripped his hand as tightly as she can, as Atla leaned her head against Abyss' shoulder, and Abyss does the same thing back to Atla. Seems like he is getting used to her presence in a more comfortable way.

Later...

Abyss and Atla began to walk down to what appears to be a hill made of grass, as Abyss felt like he needs to be in something in order to make himself feel like he is at home. Even though he has said this many times to himself and had thought of this many times to himself, he is going to think this to himself again. He still can't believe that this has happened to him. He still canMt get over the fact that what had once been a beautiful world has turned into a biome of the red Dead Cells that are out there, looking for food.

As he goes there, he then spots that there is someone there, and he goes to see who that someone is.

Ganyu is shown to be lying on the grassy hill, as Abyss spoke out to her.

"Heya, Ganyu. You enjoying this place so far?"

Ganyu nodded, as she than stood up, and looked at Abyss in the eyes, as she than spoke out to her kind friend.

"I do. I will admit that, even after all the stuff that has happened to your world, one of its many places still looks beautiful, even after all of this that lead it to become the way that it is."

Abyss nodded, as he sat down onto the ground, with a rather unhappy expression on his face, and Gamyi seems to notice this unhappiness that is present, as she than sat up and began to speak out to Abyss, concerned.

"Sans, what is wrong?"

Abyss looks at Ganyu, a little bit distressed, but he calms down, as he than spoke out.

"It's just that...I just...I just can't believe...what has happened to my world. It was once a lot more beautiful than it is right now. It had so many friendly people, a city that cares so much for its citizens, and a lot of beautiful wildlife, and now, now this happens. Everything that I had known about this place, it is almost all gone. Some of my friends, they are almost all gone, and now, everything, it won't be the same again. Everything I had is fine, everyone that I had known is mostly gone. The whole world as I had known of it, it has all crumbled down. I can't be the same again, my world will never be the same again."

Abyss than tucked his knees to his face, as Atla hugs him very tightly.

"I don't know how I am going to be able to deal with this."

Atla than leans in against Abyss, as he spoke out.

"Sans, it's okay. You may have lost so may, but you did not lose your others friends still alive, you did not lose your brother, and you did not lose me, you even made new friends."

Ganyu than puts a hand on Abyss' shoulder, as she spoke out.

"You may have lost so many. But you do not fall in any sort of way. You still keep on going. That means that you did not lose everything. You still have time to do something about this. The fact that you are able to keep on moving, means that you are not going to stop at any time, and that you are able to keep on going, regardless on how painful it must be to you. You may feel like that you are alone, but the truth is, you are not. You are never truly alone. You have found people that hav estates by yourself, friends that have aided you in stuff that you could not bare to do by yourself, and now, you had found me, and here I am, being able to help you in whatever it is that is happening to you. So please, Sans, allow me to help you, and allow your friends and family to help you.

As Abyss looked down, with a feeling of happiness and relief growing inside of him in the fact that he is not doing this all alone, he than hears a voice spoke out.

"Perhaps I can be of assistance in making you feel better."

Abyss and the others looked up a little bit, before they than turned around to see someone that they did not expect to see.

It's another Sans, but this one has a golden crown on top of his head, wears yellow, green, and black clothing, and has royal, golden eyes, and he appears to have a very nice aura to him. In fact, when he feels this aura, he felt like he is feeling many of the happiest moments that he has had in his entire life. The aura and the magic that he is feeling from this Sans, it feels like the total opposite to Nightmare, who had an aura that was filled with so much despair and damnation that Abyss can hardly stand it. He only stood a change against that, because of the e fact that his CELL Core is trying all that it can to keep Abyss from growing insane. This made Abyss surprised, as he spoke out to this mysterious Sans that's behind him.

"Huh? Who are you?"

The other Sans smiled at Abyss, and spoke out.

"My name is Dream, I am the Guardian of Positivity. And you must be Abyss. It is nice to meet you in person for the first time, even in this one little space. Ink has told me that you had met him once."

Abyss' eyes widened, due to Dream knowing Ink, but he than realizing spoke out before he can stop himself.

"Dream...wait a second. You wouldn't be related to another Sans name Nightmare, do you?"

This surprised Dream, as he spoke out.

"You know of him?"

Abyss nodded, as he than spoke out to Dream.

"Yeah, he and I fought against each other. I barely got away from him. And it sounds like you know of him."

Dream nodded, as he than spoke out, unhappily.

"Unfortunately for you, yes, I do know of him. Because, honestly...Nightmare...

...he is my brother."
