-Izuku POV-

When I looked up I saw an elderly man with strange clothes and a big wooden cane looking at me, he also had a very long beard.

==============================

~~Character bio~~

Name: Shigekuni Yamamoto-Genryūsai

Age: Unknown

Quirk: Unknown.

It is known that Yamamoto can create and manipulate fire. To what degree however, it is unknown.

==============================

Izuku: 'His aura is something else! How strong is he?!' Yes of course.

???: Thank you.

He sat down oposite from me and after a few moments of silence he spoke.

???: I'm sorry. I haven't introduced myself. I'm Shigekuni Yamamoto-Genryūsai. It's pleasure to meet you.

Izuku: Izuku "Yagi" End. Likewise. May I ask. What is that you need? Someone with such high power level as yourself are not normal people.

Yamamoto: *chuckle* As I've heard the rumors were true, a new King of END really has high senses.

At this the tension between us rose but it very quickly dissappeared as the maid approached us. And put my tea and some cookies on the table.

Belfast: Here is your tea nya~. And some cookies for the little girl nya~. *looks at Yamamoto* Would you like to order sir? Nya~.

Yamamoto: Some strong tea would be much appreciated.

Belfast: Understood nya~.

As she walked away the tension between us returned as we continued to stare at each other while Eri was munching on the cookies.

Izuku: *serious* How do you know that?

Yamamoto: There is no need to be hostile. I simply heard rumors and decided to see for myself. Now I can say, you're a good kid, you have a golden heart.

The tension dissappeared but I was still on guard.

Izuku: *sips tea* They make nice tea. Now back to the subject. You know about the existence of the END. That begs the question, what business do you have with me?

Yamamoto: That is simple really. I want an alliance between your kingdom and the Soul Society.

Izuku: Soul Society? I thought it was just a myth. That it dissappeared without a trace a few hundred years ago.

Yamamoto: Indeed. But in truth we were transferred to a new dimension. To the one where we were needed. I somehow remained with an ability to travel to this world and back. So when I heard of a new King I immediately started the search. I must say. You gave me some trouble, you were trained very well in hiding your aura.

Izuku: Thank you. But again, why is that you want an alliance?

Yamamoto: I've been getting reports of some endermen attacking some of our reapers and dissapearing without a trace. One of the survivors have described one of them. They had Hollow masks on their faces and I fear that something bad will happen in the future. And when it does, it would be helpful to have your support.

Izuku: That is strange, yes. *sips tea* I've had some reports of a missing endermen. And it seem like something or even someone has captured them and controlling them. But I have a theory that they can be brought back to normal if exposed to one of the END Crystals.

Yamamoto: So does that mean?

Izuku: Yes. The alliance between Soul Society and the END dimension will happen.

Yamamoto: Splendid.

Belfast then came back and put Yamamoto's tea on the table.

Belfast: Here you go sir, nya~. If you'll need me just call me nya~. *walks away*

Yamamoto: *sips tea* Indeed they do have good tea here. Now then that is done. I have a question as well. Who's the little girl to you?

He gestured to Eri who was still eating cookies.

Izuku: You could say that she's my adopted daughter. But I'm thinking of changing that when she's older.

Yamamoto: At such young age and already a father. You know, I've been searching for someone to teach.

Izuku: What are you implying?

Yamamoto: I want to train you. Not only in our ways but as well as to how to go to our dimension.

Izuku: But why?

Yamamoto: As I said. Something bad is going to happen and I fear I won't be alive after that. So I want to pass down my knowledge to someone who can take care of everything when I'm gone.

Izuku: *inhale* *exhale* If that what you want then I can't deny such a request.

Yamamoto: That's good to hear. Now then, we'll start your training in a few days.

Belfast led them to the table Izuku was at but upon arriving they saw the money on the table under the cup and Izuku as well as Eri and Yamamoto were gone.

Unryuu: Seems like we were too late.

~it's timeskip time~

-3D POV-

It's been a year and 2 months since Izuku met Yamamoto. In these 14 months many things happened. Izuku and Yamamoto officially made an alliance between Soul Society and the END dimension instead of only by words. In this time Izuku helped Eri with her nightmares and PTSD as well as to control her quirk. When he brought her to the END she was scared a bit but after some time she quickly became friends with all of the endermen as well as some other creatures in the END. She started to call Ranboo an Uncle and when Yamamoto visited to train Izuku she started to call him Grandpa. In the middle of the 2nd month the dragon egg hatched and now there were 2 Ender Dragons. The small dragon quickly warmed up to Eri and became her best friend. (Here's the looks of the dragon)

Now onto Izuku. For his training Yamamoto wasn't going easy on him. First they unlocked his Reiryoku and its amount was almost as huge as Yamamoto's. Yamamoto started training Izuku in using it as well as teaching him many techniques. Seeing that in swordsmanship Izuku was on par with him he determined that it was unnecessary to train it but they did spar from time to time for Izuku not to get rusty. On the 7th month Izuku was finally able to unlock his zanpakuto and started to train with it. After a year passed Izuku mastered almost everything Yamamoto taught him but he still couldn't figure out the name of his zanpakuto. After that Yamamoto left to take care of the soul society and the problem that have been rising when he was away. In the last 2 months Izuku mostly spent time with Eri and taught her many things she needed to know. As of right now, Izuku was talking to Ranboi while waiting for Eri. Who after a few minutes ran up to them.

-Izuku POV-

Eri: I'm ready papa.

Izuku: Alright. Ranboo did you get it?

Ranboo: Yes. A Diamond VIP ticket to the concert of K/DA. *hands him the ticket*

Izuku: *takes the ticket and places it into his pocket* Good. *picks up Eri* Lets go then.

Eri: *waves at Ranboo* Bye uncle Ranboo.

With that we teleported a block away from the building where the concert was happening and I started walking there.

Eri: Why couldn't we just teleport there?

Izuku: Because it would look bad if some random people appeared there out of nowhere. Also I don't understand why you like their music so much.

Eri: Because it's so cool! My favorite is Kai'sa. I love how she dance.

Izuku: I don't know who that is but ok.

After a but of walking we approached a huge building with a very big line at the entrance. I walked past them and went to the VIP entrance and was stopped by a bouncer.

Bouncer: You VIP ticket.

I took out the VIP ticket and showed him. He nodded and opened the door for us and when inside we were escorted to the Diamond VIP seats. I told Eri that I needed to use the restroom and left but not before leaving an assassin enderman to protect her. On my way to the restroom I saw 3 suspicious men sneaking around so I decided to stick to the shadows and followed them. After a few minutes they stopped in front of the door that had KDA written on it. I knew where this was going to I quickly knocked the two men who were looking around while the third was picking the lock. I stood behind him and cracked my knuckles and he shakingly turned around and looked at me and I knocked him out. Now I need to bring these three to the security.

~a little timeskip brought to you by Eri being cutely angry~

-Izuku POV-

When I came back to Eri I noticed that she had a face of amazement and that I missed the whole concert. Was I really gone for THAT long? Anyway I picked up Eri and she looked at me.

Eri: Where have you been papa? You missed the show!

Izuku: Sorry snowball. Some things came up and I had to deal with them. Are you ready to meet them?

Eri: Wait we're going to meet KDA?

Izuku: Yes. As a diamond VIP we get to meet them and spend the whole day with them.

Eri: *big smile* Yaaaaaaaaay!

Izuku: *almost gets a heart attack cos of her cuteness*

Then a man in a suit came up to us and gestured to follow him. While walking to their room I dismissed the enderman and upon arriving he opened the door and we walked in. In the room I saw the KDA who were relaxing on the couches.

Fox ears: Oh shoot we were supposed to meet the diamond VIP as well! *notices Izuku and Eri* Aaaaaaand they're here.

The rest of the girls looked at us and silence fell until Eri jumped out of my arms and ran and hugged one of the girls legs and looked at her with a smile.

Eri: Oh my papa! You're Kai'sa! Can I have a photo with you!?

Their attention turned to her and I swear to whatever God there it i could see them getting heart attack from Eri's cuteness alone. It is official, Eri is a weapon of massive cuteness overload. They stated to talk with her and take pictures etc, while I just zoned out.

-3D POV-

Ahri: Wait did I hear you right? You said "oh my papa"? Maybe you meant "oh my god".

Eri: No. I meant papa. He is strong and he is a king of our own world.

Evelynn: And who is your papa?

Eri: Him. *points at Izuku*

The girls: Huh!?

Akali: But how? He looks no older then 16!

Eri: I don't care. My papa is the best papa in the whooooooooooooooooooole world.

Ahri: 'TOO CUTE!' *passes out*

Seraphina: Welp, there goes Ahri. So, what do you want to do now?
