Next day, after the battle has ended, at Y/n's home. Irene and Erza are laying on a deck chair, looking at Y/n training with his father

https://youtu.be/xaDngop_j_c

Lucy: (Waves) Hey guys! Are we to late for lunch?

Gray: Would be really sad if we were.

Wendy: I hope not, his cooking is really amazing.

Juvia: His cooking really makes me excited.

Carla: Let's just hope Natsu won't burn it.

Natsu: I can behave too, you know!

Happy: Says the guy who always burns my fishes!

Frost: Good to see you Happy!

Happy: Frost, let's have an eating contest between us!

Frost: Aye! You will lose! (Starts to devour his ice cream, as Happy gobbles down his fish)

Carla: Oh dear, how childish.

Erza: No, you're just in time. Y/n is soon done with the training and lunch should be ready shortly.

Irene: Your fiance is really powerful, he fixed half the city in an instant.

Erza: Yes, he has the power of his father, but I don't like it that he's already back at training with him. The injuries are still fresh. (Holds her baby cradling it slowly in her arms)

Irene: I still need to process that Silvia is half Saiyan, the tail looks so fluffy.

Erza: Bahamut gave me an ability to have a tail once, all of my armors have a hole at the place of it. Now it's possible for me to feel how it's like to be a Saiyan, with the drawback that the tail makes me very sensitive when it gets squeezed.

Lucy & Juvia: Silvia looks so cute when she's asleep.

Irene: You have the tail right now?

Erza: Indeed, I made it so that I can always have the tail when I want. It makes me even more attracted to him and even closer to my sweet baby.

Irene: I see Y/n has done a lot, but he still has to hit his father in the training.

Erza: I forgot to tell you, if you actually grab the tail and stroke it, you make him aroused.

Irene: Really? (Grabs Erza's tail and strokes it softly, as her face blushes and falls back on the deck chair with the baby in her arm) Hmm... Interesting.

Erza: Mom, don't ever do it again!

Irene: I was just curious.

Bahamut: (Smirks) You are as slow as ever, boy.

Y/n: (Smirks) We have played around enough now, time to make it serious! (Transforms into Super Sayian God)

Bahamut: This might be a problem. (Gets kicked into the ground by Y/n) That actually hurt.

Y/n: Bring it on Dad! I'm all powered up now! (Bahamut and Y/n collide with their fists, making tremble ground)

Irene: How did Y/n react when you told him you're pregnant with Silvia?

Lucy: Oh yeah, I want to hear it too!

Juvia: I want to know how the mighty Fairy God reacted!

Wendy: I don't know if I want to hear it.

Erza: (Sweating) Well...

Flashback

Y/n Pov

I was at home, waiting for Erza to return from Porleyusica, to know what she has. Suddenly I felt a chill go down my spine and a very angry energy and heavy footsteps coming closer . Shortly after Erza kicked open the door and made the wall brake as well, I was scared and sweating buckets from how she was looking at me.

https://youtu.be/BS74dVVh-No

Erza: (Angry Grabbing his collar) Y/n! You made me pregnant you baka!

Y/n: (Sweating) You told me that you want to have a baby. I will think about what we have to do, I will go and make some dark guilds atone for their sins for now and tell you what we can do to prepare us when the time comes.

Erza: (Angry pulls out a sword and points it to Y/n's crotch) Atone for your dick first, Y/n!

Y/n: (Scared falls down) I'm sorry Erza! Don't cut it off please!

Erza: (Laughs) I'm not angry Y/n, I only wanted to scare you. I'm happy that we'll become a real family now.

Y/n: (Pale face) ...Erza, you really scare me sometimes but, (Kneels down and hugs Erza's belly) I'm happy as well for us to become parents.

Erza: You will be a good father, I know that. I saw how you behaved around Wendy, always helping her and showing her how to improve without getting to much pressure on her.
(Y/n stands up and kisses Erza)

Y/n: And you will be a good mother as well, strict but not harsh.

Erza: I already know that you will train it in martial arts and show it how to use it's power like you did when you were young.

Y/n: Training is very important for a Saiyan, Erza. You will make it learn on how to fight with swords, right?

Erza: You can bet on that. It has the DNA of the two of us in it, so it's going to have a lot of fighting spirit.

Flashback end

Irene: He took it well I see. And how did you react when you found out you're pregnant?

Erza: I can tell that too.

Flashback

Y/n: Erza, are you sure you don't want me to go with you to Porleyusica?

Erza: I can go on my own, no need for you to be there. You can wait here at home. (Erza leaves to go to Porleyusica)

Erza: Porleyusica, I need to ask you something very important?

Porleyusica: Let me guess, it has to do with your body Erza?

Erza: Exactly, I need to know something important about... (Mumbles) B...babies.

Porleyusica: I think I have something for that. (Searches for something and takes out a vial with a transparent liquid in it) Take this and spit inside of it, if it turns blue you are pregnant, if it turn green you have nothing to worry.

Erza: (Nervous) Fine. (Spits in it and waits nervously on the result) Porleyusica, is there something I need to know if...

Porleyusica: I will tell you when the color shows it. (Erza looks at the changed color with worry) Congratulations miss Scarlet, you are pregnant.

Erza: (Looks at the color with mixed feelings) P...pregnant? ...I can't believe this. (Tears form in her eyes, as she covers her mouth with her hand) What should I do? I mean, the time is good for it to happen, we have nothing to worry right now, but how am I going to do all the things at home? And the investigations will be harder with a baby growing inside of me.

Porleyusica: (Smacks Erza's head with a newspaper) Don't overthink it! You will be fine! Just follow what I will tell you and get these books. (Hands her a note) First: No drinking alcohol from now on until the baby is born and afterwards, because you will have to breastfeed it. Second: No stressful activities. Third: Stay at home and roll yourself in a blanket and let your fiance do all the chores from now on until the baby is born. Fourth: Stay calm at all time, any emotion that causes anger or stress is bad for the baby and for you. Fifth: Let your fiance spoil you with food all the time and have enough food at home for your food cravings that will happen in your pregnancy.

Erza: At least I don't have to miss on eating sweet things, so it's not that bad after all.

Porleyusica: Now get out of my house! I don't like humans even if they are pregnant! (Throws her out) And come here every few days for a check up on your pregnancy. Now square off!

Erza: Thank you miss Porleyusica. (Smiles happily looking at her belly) And now I will have to tell Y/n about it.

Flashback end

Erza: I was frozen on the spot, after Porlyusica said to me that I will be expecting a baby. Not knowing if I should be happy, but I knew that I was happy as the tears I had were tears of happiness and I was smiling with content, as I finally had a baby from Y/n.

Irene: I'm happy that you got someone so caring. Your father was an asshole, he tried to kill me and my unborn baby, because I turned into a dragon and I didn't want to give birth to you in a cell. So I placed an enchantment on my baby bump. I had you inside of me for more than four hundred years, until Zeref had changed me back into a human. Then I was finally able to deliver you.

Erza: So I'm the daughter of a dragon? I'm a half dragon? Now I know why I was able to learn Dragon Slayer magic so easy. Your clothes, I kind of like the look of it without the over sized hat.

Irene: I have a few spare in a suitcase. Their size can adapt to your body.

Y/n: Enough for today. Lunch is ready! (Holds his hand over the chest wound) I'm glad you made it heal Dad, but you could have just let the scar stay and not make it barely cover it.

Bahamut: It was Erza's Idea, she wanted you to suffer for a bit more for making her think you died.

Y/n: I should have known it, Erza really hates it when I make her worry so much.

Erza: I need to change the bandages of your wound, or else It will not heal well. (Takes them off)

Y/n: Do I really have to? (Erza applies disinfectant) AAAAAAAAAAH it burns!

Erza: (Giggles) You're really weird, you can fight while being highly injured, but a bit of disinfectant makes you scream in pain like a baby.

Y/n: It's the alcohol in it that burns.

Wendy: Y/n and Erza can you please sign this? I need two adults to sign it, it's for something important.

Y/n & Erza: Sure. (Sign it) What's it for?

Wendy: (Smiles) Just an adoption certificate. (Erza and Y/n look at Wendy in disbelieve)

Y/n: What do you think of this Erza?

Erza: I don't mind it. Wendy my daughter! (Hugs her)

Y/n: If Erza doesn't have anything against it, than why should I. Come here Wendy! (Pats her head)

Wendy: Thank you Erza and Y/n.

Erza: Call me Mom and Y/n Dad from now on.

Y/n: Sure why not.

Irene: Why didn't you ask me Wendy?

Wendy: Well Erza and Y/n are already like my parents from the beginning, since I met them.

Y/n: You know what that means from now on Wendy, right?

Wendy: I have to look after my little sister now?

Y/n: Correct. 

Erza: (Erza wraps the wound in fresh bandages) Done, we need to change it twice a day. What is on the table for today?

Y/n: I made Sushi, Udon, Yakitory, Ramen and Donburi as main dish and Wagashi as desert.

Irene: This looks so appetizing! You really hit the jackpot with him Erza.

Erza: Thank you, now let us eat. But how did you make this without cooking?

Y/n: I already made it and stored it in an area that stops time, so it stays fresh.

Irene: (Eats a piece) It tastes so good... My body is twitching and having a foodgasm.

Erza & Y/n: (Shocked) ...

Bahamut: That sounds a bit weird to me.

Frost: I really like our new family, it's a lot more lively now.

Y/n: You're right Frost. Irene your clothes are still ruined, don't you want to buy new ones?

Irene: Well, I wanted to buy some, but I need money first.

Y/n: Don't worry, I'm going to buy them with you and then we will do some job requests together, so you too know how it's to be in a guild.

Irene: That's very kind of you, Y/n. I'd like to try this next, Gotcha Pork Roast from a very famose cooking show.

Y/n: The recipe looks good, I will try it. What's the name of the cooking show?

Irene: It's Food Wars, it's the best cooking show I have seen, with perfect recipes to make at home.

Y/n: I heard of it.

Lucy: I saw the show too, it's a bit strange but fun. I wonder why Gray wasn't in it.

Gray: Why would I be in a cooking show?

Juvia: You would cook them to the ground, Gray-sama.

Later the same day

Y/n: Buy whatever you want Irene, I will pay it.

Irene: I will bring a lot of clothes.

Three hours later

Irene: All of them.

Y/n: Four millions on clothes? Damn. What did you buy Irene?

Irene: I looked into Erza's wardrobe and saw some interesting pieces I wanted as well.

Y/n: Hmm, like the cat costume here?

Irene: It looks good on me.

Y/n: Erza will be shocked, to see her mother is the same as her.

Erza: Here you are, you two. How long are you going to need... Why are all my clothes here?!

Irene: I liked them so I bought them.

Erza: ...

Y/n: Now let us go back home and let Irene change into her new clothes.

Back home

Irene: So how do I look?

Bahamut: Like a knight in revealing armor.

Erza: Why are you wearing my forth model of the Heart Kreuz Armor?!

Irene: It has something that makes it look more mature than the others. And you are wearing my clothes without the oversized hat.

Erza: This was the armor I was wearing when I already had Silvia, for a more comfortable use as the chest was bigger and still is. And I was curious on how it looks on me so what do you think of this look Y/n?

Y/n: (Nosebleeds looking at Erza in the clothes of Irene) It looks good and gives protection, so why not. Let us go to Fairy Tail now. And Erza, you look absolutely hot in it, I might want to fight you..

Erza: (Places her hand on Y/n cheek) I know what I want to do afterwards. (Winks at him and walks to the living room)

Bahamut: Their behavior is literally the same!

Y/n: Yea talk about being a perfect copy, Erza constantly had the guys looking at her when she was fighting in her skimpy armors and now Irene is literally doing the same.

Irene: So Y/n, is Erza the same as I am? I mean in bed, as I'm very fierce when doing it. Places her hands on his cheek)

Y/n: (Thinking: Is she trying to get a move on me?!) (Sweating) I...I think yes, she likes to dig her nails into my back a lot and she's very energetic on it.

Irene: (Smirks) I knew it, she's really just like me. Good job at giving her a baby, Y/n. You're very strong indeed. (Pats his shoulder)

Y/n: (Screams internally)

Fairy Tail

Makarov: Good day to the new family.

Y/n: Hello Master Makarov, are the S class requests here already?

Makarov: Yes, upstairs, as always.

Y/n: Hmm... Eliminate 100 monsters. Beat the bandits in the mountain near violet town. Oh this looks like a good one: Fight against four titans to protect Clover Town.

Irene: Titans? I only heard of them in rumors, they are supposed to be large rock type monsters who take a lot of damage to kill.

Y/n: That's why this is a decade quest, only the strongest can beat them. We will take all three of the S rank requests, Mira!

Erza: You want to make us fight against four of these things, are you insane? We barely stand against two of them!

Y/n: Trust me, we are a lot stronger now.

Fighting the Titans

Erza: Stronger, huh?

Y/n: I'm not using my full power, so stop!

Irene: Well, what are you waiting for then?

Bahamut: This is not how you are normally, you are too weak now.

Frost: (Smiles evil) You stink Y/n, just give up and let Erza handle this, cause you're never gonna win.

Y/n: (Angry) WHAT DID YOU JUST SAY?! I prove you how strong I am, by defeating them myself!

Shortly after

Frost: You showed them that fighting the God Dragon Slayer is going to make them confess their sins.

Y/n: You weren't to sure of me earlier.

Frost: Cats have a really bad short term memory, you know.

Erza: Alright, you proved to be strong. Are you still mad?

Y/n: (Sulky) Yes. (Erza Kisses Y/n)

Erza: Now it's better, let's go to the next request.

Irene: How did he manage to suplex a Titan?

Bahamut: He has his methods.

Fight against bandits

Y/n: I usually use my fists when fighting bandits, Irene. It makes more fun.

Irene: I will try as well. (Kicks a bandit in the face)

Erza: Finally, Bahamut why are you always with us, but never fight the enemy?

Bahamut: Someone has to look after the baby, so I take it with me and you are not to far from it to feel like you abandoned it. And my own rule as God makes it impossible for me to fight, it's a personal decision. Even though I attacked those dark guilds, but that was a lot of fun.

Erza: Thanks for explaining it. Now let's beat some bandits!

Fight versus 100 Monsters

Irene: This is quite challenging, the monsters aren't strong, but the number makes it hard.

Erza: That's why we love fights versus a lot of enemies, right Y/n?

Y/n: Yes, I really can let lose here. Next time we are at the Grand Magic Games and the Pandemonium is on, I want to fight them.

Erza: All down, let us get the reward and go back at the guild.

Back at the guild

Makarov: I see you are done. How was it?

Irene: We had a run in with some bandits. Y/n beat all four Titans on his own. Oh, we took down one hundred monsters as well.

Makarov: Sounds wonderful, we are happy to have a new member here.

Gildarts: This armor looks good on you, Irene.

Irene: (Blushes) Thank you for the compliment.

Y/n: Looks like someone has an eye on Irene already.

Erza: Gildarts? It might work out well, better than the younger ones of our guild.

Y/n: Yeah, I don't think Laxus would be good for Irene.

Shortly after

Erza: Do you know where Irene is?

Y/n: I saw her go with Gildarts...

Cana & Erza: WHAT?! NOO!

Y/n: Oh crap.

Mavis: Be happy for your parents Erza and Cana, they are made for each other.

Cana: Well, I guess it can't be worse than not having parents. But still, Erza as my possible sister? I don't know.

Erza: How much can change? It's not like Gildarts really thinks I'm his daughter then.

Cana: You know how he was when he found out that I'm his daughter, have fun with that.

Erza: (Panicking) I don't want to be crushed to death by his hug!

Y/n: Calm down Erza, if he's going to hug you I jump in front and take it.

Erza: The baby has feeding time now. (Un-equips her armor) There you go my baby.

Y/n: I wonder if any of the other female members of Fairy Tail envy you for having a baby.

Erza: Probably Juvia.
