It has been...a month, since Error had taken Mione Gremory from Rias Gremory, after what she nearly done. And the days have been...weird, to say the least, Error had been doing all that he could to try and make sure that the kid, Mione, is living a comfortable and very carefree love as he could, as well as make sure that Rias Gremory does not find her, lest she tries to use her again. And luckily, he does not have to worry about some stuff with the kid, especially when it involves the baby soiling herself, which she thankfully doesn't do. So Error is safe from that. Thanks to that, it made his ability to take care of the kids much more easier then other parents. The kid, Mione, she has inherited both of Error's powers, meaning the strings, bones, glitches, and Blasters, and Rias Gremory's Power of Destruction. However, on the case of Mione, the Power of Destruction has become a part of Mione's Cosmic Essence, meaning that, if she were to have kids, they'd inherit that Power. And honestly, this is so what fitting for Error, as Error is a type of destroyer, and Rias has the Power of Destruction, so naturally, the child is a very fitting mix for Error himself. Lala helps whenever she can, especially because of the fact that Lala had done, 'it,' with Error, along with the members of the Crimson Squad, and Error knows what this means, which is not bad for him, but he is rather unprepared with the amount of kids that he will have to raise sometime in the future. He just hopes that he is able to deal with it, and raise the children he'll have correctly.

But as that happens, he turns to the backyard door being open, and he looks to see that there is a small humanoid figured sitting at porch, near some potted plants, and it is a girl that Error knows of, for she had been living in this house before he broug  it Mione home.

On the porch, is a young girl, about a foot in height and at the size of an infant, with green hair, 2 toes on the feet, and oddly, a flower on top of the head. This is Celine. She is an infant girl that Error had picked up, thanks to Lala. Orignally, Celine used to be a large alien plant that Lala had given to him and put into his backyard.

And needless to say, taking care of a sentient alien plant was no joke, but the plant that he had raised thanks to Lala is able to like him, even though it is not careful. But then, out of nowhere, became sick, and Error thought that it was going to get better...but instead, the plant turned into the humanoid form that had now became Celine currently. Heck, he had Celine before he had Mione. And Celine has been living with Error since. She even considers Error as her papa. And this embarrassing moment, to Error...he hopes that Error404 does not find him. And luckily, Celine turned into her humanoid form on time to meet up with another girl, who has silver hair and a horn on top of her head.

This is none other then Eri. This girl was found by Righteous when Eri was escaping from a bad person with a bird mask named Overhaul. And Error, he got Eri away from him and handed Overhaul to the police when he was done, and this allowed Eri to live with Error. While at first, Eri could not smile, interactions with Celine made her finally feel happy for the first time in her entire life. A happiness that she never thought that she would be able to feel in living. And like Celine, Eri refers to Error as her, papa. This made Error embarrassed to the bones, as he does not expect for something like this to happen. He could almost feel himself fainting of bashfulness at what it is that is happening. Error even was able to help her gain control over powers enough for her to be careful with it.

Error sighed, as he looked down at the pitch, seeing both Eri and Celine together, acting like sisters to one another, with Eri being the older sister to Celine, who somewhat acts as the youngest. Error smiled at the sight of the both of them being as happy as they can be, and Error spoke out.

"I swear, I don't know what I will do with these 2 rascals now on my life. The both of them are just made for each other."

As Error looked, Celine then hops off and began to run around the entire backyard, and for someone that is likely at the age of an infant, she runs very, very fast, as Eri then tries to catch up to the little flower girl, although Eri is not that fast, as she fails to try and tag the girl.

Error, deciding that he does not want Eri to accidentally hurt herself while doing this, raised his blue strings and wrapped then around both of the little girls, and picked them all inside of the house, as he spoke out.

"Okay, I think that is enough of that, you both. Besides, I made some lunch for you both. Do you all wanna eat?"

Eri and Celine look like they want to protest, but then their stomach growled, and they both looked up at Error and nodded their heads. Error smiled, as he then used his blue stirngs and gave them bowls that are filled with Ramen, the first time he is in making this meal.

Right now, Celine is eating some Ramen with Eri, who is doing the same, due to the fact that Error had been the one to make it. Normally, he's make cookies, as Error404 had been the one to make them and have him eat them. But Error decides to make something new. It took a bit of time and some taste tests, but eventually, he was able to get the result that he wanted. Error smiled, as he sees that the both of them enjoy the ramen that is served to them. And needless to say, Error smiled, seeing that is a sorry of accomplishment that he has made. Honestly, he hopes that the ramen he has made will be enough to make them full. Error sighed, as he puts his hands in his pocket, and he then closed his eyes, before taking out a cookie jar, and began to eat some cookies out of it, liking the fact that it is his favorite chocolate chip cookies. While he is eating, he then decides to carry some of his cookies to the girls, and when they saw them, they then grabbed onto them and began to eat them, liking the taste of the chocolate chip cookies as well. Needless to say, it sends that his tastes are now passed on to the 2 little kids as well. Now...now they are able to enjoy the childcare chip cookies just as much as Error does. Seeing them like his favorites snack puts a smile on his face. He even stuck out his 5 tongues in a very playful way at the sight of this.

After they are done with the Ramen and Cookies, they hopped off of their seats and stood up, as they both began to have their usual fun again. Error, as he sees the young kids have their immensely great fun time that they are having now. It almost reminds him of when he had taken care of Papyrus when he was just a very young kid, as Papyrus is always a very good baby for Error to raise. And being with Error Papyrus, it reminds him of that time. He may have forgotten his times as Geno, but he can still regain some memories that are precious to Geno, especially the times of when he is a bit more younger then before. As Error looked down, a knock on the door was heard, and Error came to open and answer it. And when he opened the door, it is someone that he did not expect to see to arrive at his place.

"Oh, Hello Homura. I see you decided to come and visit me."

Homura smiled, as she then spoke out to the Destructive Polothorn.

"Well, I figured I should come, especially since I want to know how Mione's doing."

Error then turns to the side for a bit, as he then spoke out to Homura.

"Ehh, she's doin' fine. Acting as normal as any other child, although for a kid, she seems to be a little bit smarter then the normal ones you'd usually see."

Homura nodded her head, as she then turns to loom and see that Celine is here, along with Eri, as she then spoke out.

"And I see that the 2 other young girls are okay as well."

Error nodded, as he then spoke out.

"Yeah. And luckily, Yomi is not here to see Celine, otherwise, she'd go nuts."

Homura nodded with a chuckle coming out of her mouth, and she then spoke out.

"Yeah, I'll bet. She's be crazy to try and have Celine go and make bean sprouts all the time for her. She'd try to treat her like she is nothing but a bean sport factory, although she cannot really do that."

Error nodded his head, as he spoke out.

"Quite. Hopefully she does not know of this, or else I am gonna faint from frustration at what Yomi might plan and do with her."

Homura then entered the house, and as she did, the other 2 kids looked up at her and began to hug her, as Homura does the same thing. Homura smiled at seeing the kids in front to her, as Eri spoke out to her.

"Ms, Homura, you came back!!!"

Homura smiled, as she spoke out to Eri.

"Of course I did. Just thing that I would check and see how you are doing. And so far, it's been great."

Eri smiled, as he tongue stick out. And Error smiled at the sight of this as well. Seems like Homura and Eri are both gonna get along with each other, as well as Celine, since she knows that Error has a close relationship with Homura, and wants to be in with it as well. Homura smiled, as she the. Goes to Celine, and rubbed the top of her head, and Celine smiled, with Eri then getting head rubs as well on top of her own head as well. Luckily, Homura was careful in to not having the horn scratch her wrist, as Homura then spoke out.

"You 2 rascals ar so cute. Don't know how Error is lucky with the both of you."

Eri and Celine smiled wider at that, as they both heard Homura speak out onto then like this. Homura smiled as well, before she stood up and spoke it.

"Welp, I gotta go and check to see how the others are doing...and also..."

Homura leans in and whispered to him.

"Hopefully you're ready for our kids~."

Error blushed at that, as Homura then leapt out of the door, and Error, after he has heard this, held his hands to his face in embarrassment at what it is that Homura had said. What in the world is going inside of her mind right now? That is just straight up embarrassing to Error, and Homura herself should be aware of that. And she may have, but she decides to do it anyway. Well, how hopefully, he'll have the chance to be with the rest of the Crimson Squad again. After all, he is very eager to reunite with them, especially after what had happened to them from before.

He then looks to the side, and he sees that Gradient is here, along with Ikaros.

It appears that Ikaros and Gradient have returned from some other place, as Gradient smiled and spoke out.

"Hello, father!"

Error spoke out.

"Heya, Gradient. How are ya doin'?"

Gradient smiled, as he spoke out.

"I'm doing good. It's no big deal!"

Ikaros looks at Gradient with a curious look on her face, as she then spoke out.

"Master...where are we going?"

Gradient then spoke out.

"Oh, going to Outertale to visit an old friend of mine."

Gradient swung his stylus and made a profile, as Gradient says goodbye to Error, before the both of them left. Error look at this and spoke out to it.

"And just as he has appeared, he has suddenly decided to disappear into this world all of a sudden. Well, at least him and Ikaros are having fun."

Then, another voice came out of complete nowhere and spoke out.

"Wouldn't agree more then that, boy."

This made Error jump, as he thought that he is simply imagining things, but he then felt his right arm that had sensed this power, and it is a power that he knows only belongs to one person. He turns around, and it is someone that he did not expect seeing again.

"Oh, sir. I didn't think that you'd arrive at my AU. I thought that you'd stay at your AU, especially since you wanted to have it again for such a very long time."

Error said, as Error404 looked around and spoke out to his student.

"Well...I did...but I figured that I should take the time to see how you are doing, Error."

Error nodded his head, as he then walked around inside of the house, and he looks to see Celine and Eri sleeping on the couch.

"And I see you decided to take in 2 children."

Error then spoke out.

"Well...one of them...one of the kids I took in, the other was given to me by someone in my house."

This made Error404 furious at this, as he then spoke out.

"And who might this someone be that is living along with you inside your house?"

Error was about to speak at this, when Lala came out of nowhere and landed onto Error's arms, and spoke out.

"I'm back, Error!!"

Lala said, as she then hugged and nuzzled a bit at Error's face, much to his embarrassment. This made Error404 surprised, although he hides it very well, as he then spoke out.

"Oh, are you someone aquatinted with my student?"

This made Lala look and see Error404, and spoke out.

"Your student...are you referring to Error?"

Error404 nodded his head, his hands in his pocket, as he then spoke out.

"Of course. I taught him all that I know, and who might you be, if I may ask."

This made Lala smile, as she gets off of Error, and spoke out.

"My name is Lala Satalin Deviluke, it is a pleasure to meet you. And your name?"

Error404 smiled, as he then spoke out.

"My name is William...but I am known as Error404, the first Error to ever exist, and Error's ancestor. It is nice to meet you, Lala."

Lala smiled, as Error spoke out.

"Well, at least you get to meet my superior."

Then, the sound of cooing is heard, and Error404 looks to see that Mione is crawling towards Error, having sensed her father's presence, and she goes to see him. This made Error404 perplexed, as he senses that Error's power is inside of this child. Error holds his arms out, and Mione then teleports into his arms before everyone even knew it. Error looks down at the kid, and Error404 spoke out.

"Error...who is that?"

Error looks at Error404, who has a curious expression on his face, and it is obvious that Error404 is going to go onto the wrong assumption, and Error, reacting quickly, then spoke out.

"Oh, it's a little something that Rias had done. She took a piece of my magic, and used it to give birth to this little girl. She named her Mione Gremory, and so I was able to take custody of the kid, and thanks to Lala, Rias and her peerage are no longer able to remember that Mione had even existed from before."

Error404 nodded his head, and spoke out.

"I see. Does this mean that I am a grandfather or something?"

This made Error embarrassed, as he then shouted out.

"Sir?!"

Error404 chuckled, as he then spoke out.

"I knew that this was going to rile you up."

He then looks at the watch on his wrist, and he then spoke out.

"Oh, and it is almost time for dinner back in Alphatale. Chara is waiting for me!"

He then made a portal to AlphaTale; and spoke out.

"Welp, goodbye for now, Error...and I hope to see my grandkid again soon."

Error404 got away before Error could have the chance to shout at Error404, as his blush became apparent onto his face. Lala looks at Error, and spoke out.

"Come on, Error. Let's have some lunch together!"

Error looks at Lala, and nodded his head, before he spoke out.

"Yeah, let's."

Lala then began to eat as well in her own bowl, as she relishes on the taste that she is able to get from what it is that she is wearing right now. Error began to eat his normal lunch as well, as he looks and sees the cute expression that Lala is making onto her face, as she eats her meal. Obviously, he just cannot get enough of this. At least her younger twin sisters, Moro and Nana aren't here to witness this, and also did not witness Lala and the Crimson Squad making love with him.

Timeskip...

It is now nighttime, as Error is shown to be on his head, with a screen before his very eyes. He looks in Outertale, as he sees that Gradient and Ikaros are watching the Night Sky together.

Needless to say, it is a very beautiful exprirence for them both, especially Ikaros, who has ever seen the night sky to be as beautiful as expected. Error sighed, as he looks at it, with Lala at their side.

"Well...looks like Gradient is having some fun of his own with the Angeloid, huh?"

Lala nodded her head, as she wrapped her arms around Error, and spoke out.

"Yes, they are! And they both look so cute together!!"

Error nodded, and he looks at Ikaros, before he then spoke out.

'I wonder if there is any organic parts that Ikaros has that allows her and Angeloids to reproduce?'

As Error thought this out, and he removed the glitched screen from his face, Lala then decides to go right on top of him, as her arms are wrapped around Error's neck.

Lala began to embrace Error a little bit while they are both in his bed at night, with Lala speaking out.

"You know...Error...after seeing Mione in your arms like that from before, when Error404 is with you..."

She then gripped Error's right hand and puts it over her stomach, before she then spoke out.

"I wonder what our baby would like when we have it soon."

This made Error embarrassed, as he looks at Lala, and he then spoke out.

"Are you...are you for real?!"

Error then grabbed onto her tail, and began to stroke it, as Lala gasped in embarrassment from this, but she then spoke out.

"M-More..."

This made Error confused, but he does it again and continuously, and Lala began to gasp and moan in pleasure this, before she then pins Erorr, and began to go into a make out session sign him. Guess Error is gonna have more on his plate.
