S/N: C'mon, Dad! Hurry up!

Y/N: I'm coming, I'm coming...

You were currently carrying a hill's worth of suitcases full of clothes and other belongings as you as well as your family and friends were all scheduled to head for Midoriya's home world.

The suitcases belonged to all of your kids and all of your wives. Kasai was going through the same kind of thing but not nearly as much.

Meanwhile Lotus and Maquist were happy to only have one to two suitcases in hand.

S/N: So where are we going again?

Y/N: Midoriya said that we'll be going to a special place found only in his world for a week.

S/N: But you can go to other worlds on your own, right...?

Y/N: Yup. It's what I do for a living.

S/N: ...So why are we taking an Airplane...?

As S/N had pointed out, you were walking towards a large Airplane which was built specifically for Worldly Travel. You don't know the ins and outs of the thing, but you do know that it was crafted from a special material only found in the Second Reality.

Y/N: It could be so much easier if I just warped everyone there...

Midoriya: Well Y-Yeah but Nezu had a whole landing site constructed for us and all of that money would've been a waste if we didn't take a Plane...

Y/N: I guess...But if we're all going, who's gonna keep all of our students safe...?

???: Leave that to us!

You then looked over to see two individuals who had been longing to meet you. Two self proclaimed Demon Kings. Anos Voldigoad and Rimuru Tempest.

Y/N: Who are you two? I haven't seen you around here before...

Rimuru: We've been trying to get a chance to speak to you in person but you always seemed so busy. My name is Rimuru Tempest. Thank you for having me here!

Anos: And My name is Anos Voldigoad. It's an Honor to be here.

Y/N: Well...Rimuru, Anos...It's a pleasure to meet you both! But are you guys really that confident that you can protect everyone?

Rimuru: You don't need to worry about us. Our Opponents' biggest mistakes are underestimating us.

Y/N: Heh...Well that sounds promising. When we get back, I might have to rest your skills personally and see for myself! Until then, make sure nobody dies!

Rimuru: Will do. If anyone tries to cause trouble, they won't be able to handle the two of us.

Y/N: I'll have to take your word for it.

With that you waved them off and walked towards the Plane with your family. Rimuru and Anos also leaving the scene to attend to their own business.

Time Skip

After loading all of your luggage onto the Plane, you were finally able to go inside and take your seats. There was a lot more seats than expected but you noticed that a lot of other students from the academies were also on the plane. People like Shinso and Neon.

Y/N: Ahh~ What a relief to finally have those suitcases off my back...literally!

You were currently seated next to S/N and Son on both of your sides. S/N was watching a movie on the small screen attached to the seat in front of him, leaving you and Son to talk.

Son: So, Big Bro, what's new? We don't really talk anymore with you being so busy with work and stuff!

Y/N: Not too much. My class has been doing pretty well with their training.

Son: What do you think this "I-Island" is like?

Y/N: Well there'll probably be a bunch of people with unique Quirks like Deku and the others from his world.

Son: Do you think they'll be strong?

Y/N: Heh...Probably not...Deku when I first met him was a prodigy for his World's standards. I often surpassed my power back then, but if I didn't, he wouldn't have lasted 5 seconds with me in the ring.

Son: Dang, that's a downer...

As the Plane started to take off, it started moving at high speeds, even for a Plane. Eventually it was able to move so fast that it bent the fabric of Reality and warped to the next dimension.

As the Plane flew off, Rimuru and Anos watched in the distance. However little did they know that somebody was watching them in the distance.

???: Good. Now that he's gone, I can cause some real Havoc...

Time Skip: An Hour and a Half later

The Plane was just arriving into Midoriya's world, and everyone was pumped to finally be at their vacation destination.

Eye-Catch

Eye-Catch

S/N: We're finally here!

Y/N: Looks like it!

It took a little while, but the Plane eventually landed near the site, and during that process you managed to get a better look at the Island.

It didn't look like that much of a natural Island. In fact, it all seemed to be Man-made with all of the technology you were seeing.

Midoriya: It's been so long since we've come home! I wonder if anything has changed!

Uraraka: I'm getting excited just thinking about it!

Issei: So this is Midoriya's World, huh?

Ruby: It looks so cool! There's so much high tech stuff around here!

Akko: I've never seen so many machines in one spot before!!

Y/N: This looks like it'll be fun!

Eventually you were able to get off the Plane, this time with only your own luggage. Yang and the other girls chipped in to carry the rest of the luggage.

Eventually after scans and registrations, you finally managed to get to the main area, and boy, you weren't disappointed with what you saw.

There were lots of people, and the buildings were like nothing you had ever seen before. You could even see words in the distance made from Giant water sprinklers.

Jaune: So colourful! 

Skylar: This is such a nice change from the dark halls of the Chambers!!

Eventually, you all walked down a long fleet of stairs and were greeted by a lady who seemed to be there to give tours.

Woman: Welcome to the I-Island Cross-World Expo! We hope you enjoy your stay—*GASP* It's you! Mr. L/N!

Y/N: You know me?

Woman: We were told to prepare for your arrival! You came much sooner than expected! I can show you where you'll be staying!

S/N: Look at that guy! His hair is on fire! That guy's got a Gun for a hand! Does that Lady have wings?! This place is so cool! C'mon, Dad! I wanna explore!

Y/N: Hold on there, Buddy. We've gotta get settled in first!

Yang: It's fine, Y/N. You can take him to look around for a bit. We'll all be doing that right after anyway!

Kirishima: Yeah man! You're on vacation! We'll take your luggage up!

Y/N: Well...if you say so. Thanks!

With that You handed Kirishima your suitcases and went off with S/N to look around for a bit. Son wanted to tag along as well. S/N practically pulling you around as Son followed.

S/N: Let's go, Dad! This place is nuts!!

Son: Wait for me, guys!

Akko: We just got here. Is it really a good idea to let them roam around?

Yang: Y/N's been really busy with stuff recently and he's had a lot on his mind. He deserves some quality time with his family, and besides, like I said, we'll be joining him soon anyway!

Meanwhile

You, S/N, and Son were all now at a food stand because You and Son were understandably hungry. S/N and Son didn't get too much, but you got yourself three servings of full course meals. Of course to you, only three servings was merely a snack.

Sitting at a round table, You all enjoyed your food was S/N kept pointing out all of the people and their Quirks.

S/N: *Munch*...That guy's got spikes on his back! *Munch*...She's got a sword...Oh My God!! Look!!

S/N then pointed at a Lizard like man who was at least 40 feet tall. He looked like an off brand of a certain Kaiju that I can't mention because of Copyright.

...Oh what the heck. This is a Crossover Fic. GODZIRRA!

S/N: THAT GUY'S HUGE!!! I GOTTA GO CHECK HIM OUT!!

With that S/N ran off to get a closer look at the Hero which caught you by surprise. You were about to get up and go after him, but Son insisted that you relax.

Son: I'll make sure he doesn't hurt himself, Big Bro. Just stay here and enjoy your food! S/N don't go running off like that!!

You were hesitant, but even if things got bad, S/N can still handle himself fairly well. You decided to stay out and keep eating. This was a vacation for everyone after all. Let the kid have his fun.

???: Y/N L/N? Is that you...?

Y/N: Hm...? Did somebody say my name?

???: Over here!

You then looked over to see a girl who was on the taller side. She had bright red eyes and long hair of the same colour to match them. She was just sitting there enjoying a beverage as the two of you made eye contact.

Y/N: Hey there. Did you need something?

???: Oh my god it is you!! I've been dying to meet you face to face! You probably don't know me but we both attended at HOH Academy together! I'm Sarah, and I'm a huge fan!

Y/N: Oh! Sarah Bernhardt, right?

Sarah: You know who I am?!

Y/N: Well I had to sign a bunch of people in for HOH University, and I have to remember everyone's names. Although I also remember Akko mentioning you a few times.

Sarah: That's crazy! I can't believe you know my name! I remember when I first saw you, I wanted to be just like you!

Y/N: You want to get Stronger?

Sarah: Oh, no, I'm not really the fighting type. You're the Leader type! Someone who always knows what to do! I think that people like that are so cool! Do you think you could teach me a thing or two...?

Y/N: Hm. Well, I'd be lying if I said being a Leader figure is easy. In fact, it can be kinda tedious at times. Everyone looks to you for answers, and even if you don't know the answer, you still gotta do something. But I think anybody can be qualified to be a Leader with the right Mindset.

Sarah: That sounds rough...but I still want to be a Leader! I'm up to face the challenge!

Y/N: Well...I've never taught anybody anything outside of fighting, but I can help you with some tips, if you'd like!

Sarah: That sounds great! Thank's Y/N!

Y/N: No Problem!

Your conversation was then interrupted when you heard Son call out to you. You looked over to see him standing with S/N and Blake who had just arrived on the scene.

Son: Hey, Big Bro! Everybody's going to this swimming pool and Blake wants to know if you wanna come!

Y/N: Oh boy, Fan-service time!
