About a Month has passed since the entire Hydra Chambers Incident, and things have been going smoother than ever since then.

Your class of pupils was growing stronger by the day, and you've spotted some major improvements since your first training day.

After a long class of more hard training, you had once again wrapped up the session and sent your students off to the infirmary to see Asia.

Y/N: Alright, good work today, class! I'll see you on Monday! Rest well during the weekend, you're gonna need it!

Class: Yes, Boss...

???: Heh. They don't sound nearly as thrilled as they were on the first day!

You then looked behind you to see Midoriya who had also just finished his classes, approaching you. However he seemed to be in a much more energetic mood than you.

Midoriya: So, You've been teaching the same class for a month straight. How do you like it?

Y/N: To be Honest...It's pretty hard. A lot of my students have varying abilities to the point where some of them are Polar Opposites of each other.

Midoriya: I understand. I was just coming to remind you that our vacation trip is this weekend.

Y/N: Oh right! I had completely forgotten about that! Who's all going?

Midoriya: Well...We'd be here for awhile if I listed everybody one by one. But all of our friends and family are coming along!

Y/N: And have you all decided where we'll be going...?

Midoriya: Actually, Yes! We'll be going to a special place from my own world! It's called I-Island, and I think our friends would really enjoy it there!

Y/N: I see. That sounds like fun! I don't think I've ever actually been to your world before despite how long we've known each other!

Midoriya: Mhm! Principle Nezu recently contacted me and asked if we would be open to going to an exclusive event! The Cross-World Expo!

Midoriya was starting to show some excitement as he talked more and more about the whole plan. You figured that it was because he hasn't been to his home world in years.

???: Mr. Midoriya!

The both of you then looked to see someone flying towards you in the sky. They quickly touched down and approached Midoriya in a huff.

Midoriya: Oh! Hi there, Mark! Did you forget something?

You were now looking at a teenage boy. Judging from his looks, you could assume that he was around 17-19 years old. His outfit looked similar to that of a Hero from Midoriya's world, but his energy said otherwise.

Mark Grayson (Invincible)

Mark: Um...Yeah. I need my phone back. I saw you pick it up after I dropped it during training...

Midoriya: Oh! I'm sorry! I completely forgot that I picked it up! Here you go!

Midoriya then handed the young man his Cellphone to which he quickly took from his hands. You yourself had a Cellphone too, but you rarely used it.

Mark: Thanks, Mr. Midoriya!

Y/N: This one of your students, Midoriya?

Midoriya: Y-Yeah! This is one of my most powerful students! He's currently trying to master his abilities!

Y/N: Interesting...His Dimensional energy feels similar to that Cecil guy I met over a month ago...judging from that I think it's safe to assume that they're from the same world.

Mark: It's a pleasure to meet you. I'm Invincible!

Y/N: Oh? That's quite the claim!

Midoriya: Mark, we talked about this. You don't need to address yourself by your Hero name here.

Mark: Yeah I know...Mark Grayson.

Y/N: Y/N L/N. The pleasure's all mine!

You and Mark then shook hands as his grip was very firm. It was almost as if he was trying to squeeze your hand rather than simply shake it.

Mark: So you're Y/N...?

Y/N: That would be me.

Mark: I've heard a lot about you! Are you really a King...?

Y/N: Well...I'm still trying to figure it out...

Mark: Gotcha.

Watching as the two of you shook hands, Midoriya thought about it for a second, and he was really curious to see if you could teach Mark a thing or two.

Midoriya: Y/N...are you doing anything else today?

Y/N: Well...I was just gonna go home and hang out with Kirishima or something like I always do. But besides that I'm not busy.

Midoriya: I see...would you be open to sparring with Mark here?

Y/N: You want me to Spar with him?!

Midoriya: It's alright if you don't want to. I was just thinking that Mark could learn something if he faced against you.

Mark: I'm up for the challenge! I hear that you're really strong, Y/N! Think you can live up to the rumours?

Y/N: Oh most definitely...We'll start 30 feet away from each other. Midoriya, I suggest you get out of the battle zone.

Midoriya: You don't have to tell me twice!

With that Midoriya leaped away as Mark backed up to gain a safe distance. You remained standing in the same spot as Mark looked you in the eyes.

Midoriya was starting to worry a little bit. Mark had grown a lot stronger since he first arrived here at HOH University, but his power was still nowhere near yours.

Eye-Catch

Eye-Catch

Y/N: I'll give you a handicap. If you can land one solid blow on me, we'll declare you the winner! It's an old training method that one of my old teachers used back when I was a kid.

Mark: Alright, I hope you don't regret it!

Y/N: Well...Whenever you're ready.

Mark then clenched up his fists, leaped into the air, and begun his attack. Mark tried to land a simple punch, but you of course dodged with relative ease.

However with Mark's speed along with his fighting style, he had little to no control of his momentum in the air, and ended up crashing head first into the ground.

Y/N: You'll never beat your opponent with a strategy like that. I could see what you were going to do from a mile away.

Mark was quick to get up, he growled and kept throwing punches. All of which while having a decent amount of power behind them, we're incredibly sloppy in terms of coordination.

You then flicked him away with one finger as he went flying backwards. He was barely able to stop himself from from crashing into a building.

As soon as he was able to stop himself, Mark screamed and charged directly towards you. Not even showing the slightest bit of concern, you simply focused on the distance between you and Him.

Y/N: Just as I thought...

As soon as he was close enough, you raised one arm, glided your hand upon Mark's forearm, and redirected his attack to where he would simply fly right past you.

This simply sent him head first into the ground again as you looked down at him from over your shoulder.

Y/N: He's way too reliant on his power. He may be strong in general, but he barely knows even the most basic things about combat.

Midoriya: Looks like Y/N's got him all figured out...

Mark them picked himself up from the ground yet again as a part of his mask was now ripped. His power was growing, and he was starting to grow angry and frustrated.

Mark: Why can't I hit you?!?

Y/N: It's easy. You don't know how to fight an experienced warrior such as myself. No matter how many times you try to punch me, it won't work. The more times you try the same thing, the smaller your chances are of actually succeeding.

Mark let out an annoyed growl before screaming and charging towards you yet again. Your little lecture only made him more frustrated.

Y/N: Hm...

You then decided to dodge rather than simply throw him around again. His power had nearly doubled but his concentration was as good as shattered.

Y/N: Again, it won't work. It's time to end this.

You then landed and slid across the field before looking at Mark and going in for the kill. Moving towards the boy at Supersonic speeds and kicking him right in the stomach.

Mark: GUGH!!!!

Y/N: Better luck next time, Mark...

With that Mark went flying into the distance as you simply warped behind him and caught him before he could cause any actual damage to the environment.

You held Mark in your arms as he was now unconscious. Midoriya walked over to retrieve him as you spoke up.

Y/N: He shows some promising potential, but he has a LOT to learn...

Midoriya: You're telling me...I better get him to the nurse's office. I'll see you around, Y/N.

Y/N: See ya!

With that Midoriya walked away and was off to take care of Mark. You scratched your head and sweated nervously as you watched him walk off.

Y/N: Maybe I went a bit overboard with that one...

Letting out a small sigh, you were about to head out yourself when somebody suddenly spoke to you out of nowhere.

The deep and flirty like voice definitely belonged to a female, and if Issei or Mineta were here they'd probably bust a fat one.

???: My My...It's been so long since I've seen you...how could you run off and have fun without me after letting me kiss you?~

Y/N: Oh boy I know that voice...

And indeed you did. It was none other than Kuroka Toujou. Big Sister to Koneko, and a lady that's been hitting on you since day one.

You turned around to see her laying in the grass. The look of pure desire in her eyes hadn't changed a bit from the last time you saw her.

Kuroka: You've grown even more Handsome, My King~

Y/N: *Sigh*...Hi, Kuroka...

Kuroka: Awww...what's the matter? Aren't you happy to see little ol' me?

Y/N: I mean on one hand it's good to see that you're doing well but on the other hand...ehhhhh...

Kuroka: Maybe you just need a pick-me-up...

The black haired Cat-Girl then got up and walked slowly towards you. Wrapping her arms around your neck and pressing her body against yours as you simply stood there with no reaction.

Leaning in and getting closer, she then whispered in your ear as you could had to stop her there.

Kuroka: Are you looking for a good time, my Big Strong Warrior...?

She was about to start licking your ear until you gently pushed her away. This surprised her but at the same time it didn't.

Kuroka: Mm...You've always played hard to get~

Y/N: Listen, Kuroka. We were kids back then and I let you have your fun, but I'm a Married man now. I simply can't do this with you.

Kuroka: Hmm...That's a shame...If you ever decide that you want to have some real fun...you know where to find me~

With that Kuroka then disappeared in the flash of light of a magic circle. You simply sighed yet again and walked off.

Meanwhile Kaminari was watching in the distance as he had simply came around the corner at that exact moment.

Kaminari: dammit you're so lucky, Y/N...
