Right now Izuku is trying to meditate to calm down but right now he is being pestered by the guys from both class of 1A & 1B to teach them about the elements as Ojiro is the only one that ain't bothering since he knows what to do is to train hard.

Izuku: "Ticks mark" Will you leave me alone?!

Kirishima: Come on bro we want you to train us please!

Tetsutetsu: You are the manliest man ever!

Izuku: Fine, run until you pass out!

All: hai

They left leaving Izuku alone , he look at Ojiro and he had a small Element aura surrounding him

Izuku: "Smirks and thought" He is more talented than I thought

Izuku went back to the dorms as he was greeted by his wives as he then got a called from his mom

Izuku: Mom

Ei: Hey Izuku I need you to go and get some food today? Aether, Ayaka, Ayako, Lumine, Ryuri and Alisa are coming to our home.

(A/N: Ayako is Aether and Ayaka daughter, Ryuri is Crystalline's citizen name, Alisa is Asle Logia's citizen name, and this is my friend's AU) 

Izuku: Sure.

Ei: Thanks Izuku and no using teleport!

Izuku: Why not?!

Ei: Because I said so

Izuku: Fine

He hang up as Izuku then looks up to his wives

Izuku: Mom wants me to buy some stuff.

Ibara: Okay be safe.

Izuku: I will

He went to tell Aizawa which he was okay with it. Izuku walk out of the school as he began to walk toward to the grocery store. After he had everything he needed, he is walking back to his home when Izuku bump into a little girl with white hair

Izuku: You okay?

???: "Hugs Izuku" Help me... bad man 

Izuku: "Thought" Why do I sense evil intent.

???: Sorry about my daughter 

Izuku: "Notices the golden gem" Stellaron! Where did you get it?!

Overhaul: That means that you die!

??????: Bellowing Thunder!

A purple lightning struck Overhaul's head.

(Aether-New Emperor Of Khaenri'ah)

(A/N: We have been revealed in game that Aether and Lumine is from Khaenri'ah Royal Bloodline)

Izuku: Uncle Aether!?

Aether: So your father's fear was right! He's back!

Izuku: Yeah... Bring the girl out of here and tell father, aunt Ryuri and aunt Alisa about "Him"!

Aether: Got it! 

Overhaul: No you don't!

Izuku: I don't think so!

Izuku managed to hit Overhaul sending him back as Aether took the girl and run away. Izuku was in front of Overhaul.

Overhaul: My cure you will pay!

Meanwhile back with the dorms, Ochako were watching the TV as the girls from 1-A they saw the girls from 1-B arrive

Kendo: Hey girls what are you doing?

Yaoyorozu: Watching TV

Breaking New

Setsuna: It's hottie

As everyone turns the TV to see Izuku facing against Overhaul as the girls scream his name

Ochako+Ibara: "Yells" HUN!

Reporter: We see a young man facing against the leader of the Yakuza and there is no hero in sight will this young man do something let's watch 

Overhaul: You are different why can't I defeat you!? I have the Stellaron!?

Izuku: "Smirks and changes into Geo Mornach" Because... I am an Archon!

(Geo Mornach Form)

As Izuku dashes toward Overhaul as they began to fight once more as Overhaul tried to block his attacks but he is alot stronger than he anticipated 

Overhaul: I will kill you and I will take back my cure!

Izuku: Why do you want that child?

Overhaul: She is nothing more than a curse child! She killed her dad with her quirk when she was a baby, she can rewind things back and I will use her to erase quirks from the world. I like seeing her scream in pain. 

{Back to the dorm}

Ochako: He fuck up!

Ibara: Big time!

Kendo: What do you mean?

Ibara: Like his father, Izuku he has a soft side to kids and when you tried to hurt one well...

Ochako+Ibara: The death sentence has arrived!

Reporter: The young man suit has changed into some angelic armor, what is going on?

(Celestial Monarch Form)

Ibara: "Shocked and yells" HE'S USING THAT!?

Kendo: What?!

Ibara: Celestial Monarch form is Izuku's strongest form. Combine the power of the 3 strongest gods Teyvat. An elemental shot of 1% is more than enough to destroy an entire continent!

Ochako: Imagine when Izuku used 100% of his power along with his father's naginata "Dystopius Seiryuu" or anything on his father's arsenal...

{Back to the fight}

Overhaul: What is this?

Izuku: This is Celestial Monarch form... My strongest form!

Overhaul: What?!

Izuku: "Smirks" That's right!

After that, Izuku unleashed all of the techniques he had learned from the gods and even those he had come up with. If you want to describe it, it is a combo that destroys an entire planet. 

Overhaul: Damn!

Izuku: I'm not done with you!

 Izuku tossed Overhaul as he was defeated as Izuku saw that Overhaul was on his knees

Overhaul: "Scared" Please spare me!

Izuku: I don't think so now.... before you die tell me... where is your base?

Overhaul: it's by ***** and *****

Izuku: Good!

Then he pulls the Stellaron on Overhaul's body, leaving an almost dead Overhaul lying on the ground. Izuku looked at the camera and he just left there as he then went toward Overhaul's base and he shot an Elemental blast and made it explode killing all those inside of the base. Izuku then went to Tenshukaku as Nezu had to take care of this little problem.

{Back to the dorm}

Ochako: Let's go to Tenshukaku! He might be there!

Itsuka: Aren't you worried?

Ibara: Nah, he hasn't dead, yet. Besides, he has diplomatic immunity

Setsuna: How?! More importantly who train him?!

Ochako: The "Supreme Three Primodial Gods" with Crystalline-The Crystal Archon, Asle Logia-The Goddess Of Order and his father Cronus-The Primodial God Of Time And Space!

All: "Yells" WHAT!?

Ibara: let's go!

Meanwhile with Izuku as he arrive Tenshukaku to see the little girl with Ei and Mei as he landed on the ground

Ei: Izuku

As she went toward him as Ei and Mei hugged him as well as he then saw Eri

Eri: Is the bad man gone

Izuku: Of course "Takes a knee" and his base is gone also his companions won't ever bother you again

Eri: "Crying" I'm really happy thank you

Izuku: You are welcome "Head patted her head"

Eri: But I'm monster

Izuku: You aren't not a monster! What that bad man said he was wrong, you are not a curse child but a sweet little girl that deserves to be happy

Eri: You think so?

Izuku: Everyone has the right to happiness, whether human or divine.

Eri: Can I ask you a question?

Izuku: Go on ahead

Eri: Can you be my papa?

Izuku: "Blushing" Huh!?

Eri: Can you "Sparkling eyes"

As Izuku saw her sparkling eyes as he couldn't contain it as he then spoke

Izuku: Of course

Eri: Yay I have a papa!

Ei: I'm a grandma!

Mei: I have a niece!

Izuku: "Hugs Eri" How I am going to explain this to the girls?!

Aether: I should tell everybody

As the girls arrive to see Izuku hugging a little girl as they got confused

Ochako: Darling who is she?

Eri: Papa who are they?

Girls: Papa?!

Izuku: Well Eri this are your mommas.

Eri: I have two momma yay 

As the girls immediately blush seeing her like that as they all said

Girls: come to mama

(Meanwhile)

(Celestia Palace)

Cronus: So he's back.

Asle: And yet I thought we killed him in the 2nd Genesis War!

Crystalline: Just like us Archons, killing an Aeon is no easy feat. And it looks like he has a new ally.

Cronus: Now is the rush to train future generations of Archons. Because if he sets foot on Earth...

Crystalline: The 3rd Genesis War will break out. 

{Back to Tenshukaku}

Kagerou returns to Tenshukaku and finds Izuku playing with Eri

Kagerou: Uh... Izuku?!

Izuku: Eri this is Grandpa

Eri: Grandpa "Head tilt cutely"

Kagerou: "Blushing and looks away" Call me Grandpa Kagerou...

Eri: Okay grandpa Kagerou "Smiling"

Izuku: I should call Nezu

Nezu: Don't worry I'm here

Kagerou: Yeah... I won't ask!

Nezu: I have my ways and here are the papers for the Adoption

They sign it not asking how he did that but since he is Asle's pet he can do anything he wants

Nezu: I already told Cementos to make a room for Eri

Girls+Ei+Mei: Shopping!

As they left leaving both father and son alone

Kagerou: You did good son.

Izuku: Thanks dad!
