Everyone was awake and getting ready for class however Aizawa came in the dorms and called for Yajin.

Aizawa - Hidashi.

Yajin - Yes. Mr. Aizawa what's up?

Aizawa - You have a letter from ARGUS and it's urgent.

Yajin grabbed the letter and he read it but was shocked of what it said.

Aizawa - I'm going to need your answer after school today but think about it.

Yajin nodded and everyone was gonna ask but he just went straight to school ignoring most of his friends. Everyone made it to class and Aizawa explained that the Hero Licenses are nothing to slack off of. However he told them that today the entire class were going to create something new.

The class door opened and Midnight, Ectoplasm and Cementoss were standing there as Aizawa said that today the students were going to work on two new Ultimate Moves.

They were sent to Gym Gamma as everyone changed into their hero suits as Cementoss explained that everyone will have their own training dummy to practice on.

Aizawa - Hidashi. Daizo. Both of you have achieved a new level of power on the battle against Toxin but the question is...can you transform at will?

Yajin and Daizo looked at each other and clenched their fist as Yajin powered up first. He gritted his teeth as veins appeared in his neck. Yajin let out a roar as his arms, chest and legs slightly grew in size. His eyes slowly changed to red and his hair flowed for a moment but spiked up. With a massive roar, Yajin had transformed.

Aizawa - Not bad. Daizo it's your turn.

Daizo took a breath and let out a powerful yell as he powered up to his maximum. His body had the same yellow aura as well and his muscles slightly grew and Daizo's hair went from dark brown to black and his eyes turned light blue. Daizo had transformed as well.

Aizawa - Good. Now everyone take them for example. Hidashi's Kamehameha and Daizo's Final Flash are good examples as Ultimate Moves but it doesn't have to be an attack it can be a final move that will give you the advantage on any situation. Now hurry and show me you can go Plus Ultra.

Everyone went to their own Ectoplasm partner however Yajin and Daizo sparred with each other.

Yajin - I already have one attack.

Daizo - It was that Dragon attack that you used on the symbiote.

Yajin - "The Dragon Fist" It basically used up most of my power so that's a move that is only a last ditch effort. But I do have another attack in mind and it might be risky.

Daizo - I've been working on two new attacks for a while and these are gonna be my strongest attacks ever.

Kahn - Yajin. Mind helping me with something?

Yajin - Yeah sure.

Yajin went to Kahn as everyone had moments stared at them and couldn't believe that both Saiyans were the offspring's of the Hero Killer. Iida kept glaring them but slowly ignored them as he kept working on his ultimate move.

All Might came in as he started giving the students advice but he stopped when he saw Yajin. He was amazed of the many techniques he was showing off.

Yajin covered two sides of Ectoplasm and flipped over him and did the same action again, trapping Ectoplasm between 4 large energy spheres.

Yajin - "Exploding Transcendence!"

Yajin smiled as he blasted at Ectoplasm causing a massive explosion.

Ectoplasm - Great job but that isn't an Ultimate move.

Yajin - I know. I already have two Ultimate Moves but those take a lot of energy so I decided to create "Super Moves". Attacks that are not as draining but still deal a massive punch.

Everyone was impressed of the smarts of Yajin some even were inspired and created super moves of their own. Eventually the day was over and everyone went back to the dorms but Yajin went the teacher lounge as he met with Aizawa and Nezu.

Nezu - Mr. Hidashi.

Aizawa - Do you have your answer?

Yajin - I do.....I accept to work in the position of my mother in ARGUS.

Both of them nodded and explained that he will have to have late night classes and he would have to work hard if he wanted to keep up with the others. Yajin wasn't worried as he told himself that his mother still had many projects that she never got to finish and it was his responsibility to complete those projects.

(2 days later)

Everyone had their own special move as Kahn had made an idea for a new move.

Aizawa - Alright Wagashi. Show me what you got.

Kahn nodded as he transformed and everyone could see Kahn creating his Ki blade.

Kahn - This one is gonna hurt.

Slowly he started to stab himself on his left hand which made everyone worried and scared but he just smiled and once he pulled out his right arm. A new weapon was created.

Momo - A scythe?

Kahn - Amazing. With this new weapon I've grown much stronger and the potential is limitless. My Divine Wraith

He started to do some martial arts tricks with his scythe as he sliced every boulder that was in his path.

Kirishima - Man these guys are no joke.

Kaminari - Yo Kirishima. How's the move going?

Kirishima - I'm getting there. Hidashi has been helping me increase my strength with his techniques.

Kaminari - Oh yeah. He told me to control my electricity like how Midoriya does and now I've been able to be much more capable of holding more power.

Sero - Hey. Where is Hidashi?

Aizawa - Hidashi is now working at ARGUS so he won't be back until later today.

Some of the students looked worried for him but they were gonna ask him a few questions when he got back home.

(While at Argus)

Melissa - Yajin you need to put on a real lab suit. Not put over a lab coat and calling yourself a scientist.

Yajin laughed as he smiled and Melissa took a picture of him

Melissa - That is going to the album.

He laughed and both pulled out many blueprints and some drafts of ideas that Azura had left. Yajin looked determined to finish what his mother started.

(Later that evening)

Everyone had joined in the common area except for Bakugo, Kahn and Daizo.

Sato - I'm still not satisfied with my strength.

Kirishima - You tell me. I wanna get to the Saiyan Gang's level.

Ojiro - Hey if Hidashi isn't busy. We can ask him to spar with us. Old battle style.

Sato - Yeah. I wanna see if we can at least use some of his martial arts. He is a Martial Arts genius.

Kirishima - Yeah and the three of us mostly use combat so why not.

Right on cue, Yajin walked in the dorms. He was looking normal and for once ever since his return. He smiled. A true genuine smile.

Almost instantly all three of them went to Yajin asking him if he could spar and train them. Instantly Yajin said yes.

Yajin - Alright change into some shorts and meet me in my room.

The nodded and while they left, everyone else had been interested in what they were going to see and asked if they could watch. Yajin agreed and went to Ochaco's room since he wanted her to get some experience.

"Knock knock"

Ochaco - Who is it?

Yajin - Yo Ocha. It's me.

She opened the door and she smiled but she seemed bored.

Yajin - (chuckling) you good?

Ochaco - Yeah I'm just bored.

Yajin - Well I'm gonna spar with Kirishima, Sato and Ojiro. I overheard that you wanted to use your martial arts with your quirk.

Ochaco - Yeah. I'll watch you guys and see some good techniques I can pick up. Let me get changed.

Yajin - Cool just go to my room and knock I'll be sure to let you in.

She nodded and closed the door with Yajin having a good smile but it went away when he saw something he wished he didn't see.

Todoroki - I know we haven't been together for so long but I wanted to give you something for our month anniversary.

He gave her a box and Yaoyorozu gasped as she pulled out a rosé stoned necklace.

Both hugged as Yaoyorozu kissed Todoroki and Yajin's face just went back to his serious one as he walked towards the elevator. But this didn't go unnoticed by the both of them.

Todoroki - Hey you alright?

Yajin - I'm fine.

Todoroki - You don't seem fi-

Yajin - I said, I'm fine!

Yajin walked inside the elevator and went to his room and prepared the training room as eventually everyone made it. They were all surprised of the training room.

Izuku - This looks so cool.

Bakugo - It's not so impressive.

Kirishima - What are you talking about?! This is awesome. Man I wish my room was this cool.

Yajin - I'll try to see what I can do for you later. But right now let's begin.

Yajin walked out from his bathroom and everyone saw he changed into some orange shorts, he taped his feet and put on some kick boxing gloves.

Kirishima - Alright you got some more gloves?

Yajin pulled out 3 pairs of gloves and mouth pieces. Everyone stood around the ring and all three of them got in a corner trying to trap Yajin.

Shoji - Alright. No biting, no eye gauging, no below the belt and no quirks. This is just a sparring match so if you can't continue then stop fighting. Last one standing wins.

All them nodded and took their stances. Easily Yajin could see the problems in them but he wasn't going to say anything. His eyes diverted to Todoroki and Yaoyorozu for a second and he just clenched his fist more.

Shoji - ....Fight!

Ojiro rushed with a kick which Yajin easily dodged and delivered a jab to Ojiro but he quickly ducked under a left hook from Sato and flipped over a sweep kick from Kirishima. Yajin got back up and delivered two hard left hooks to Kirishima's chest and face.

Ojiro flipped over Sato and delivered a knee to Yajin's face and Sato punched him with two jabs. Yajin backed away and dodged and countered every blow that Sato tried to deliver.

Kirishima came back in and delivered a hard uppercut to Yajin causing him to be pushed back as Ojiro came in and delivered a roundhouse kick. Yajin was sent to the ground and Sato wanted to continue by trying to kick Yajin but was countered as Yajin pushed his leg back and performed a kip up and instantly jabbed Ojiro back and performed a 540 kick knocking down Kirishima.

Kaminari - Damn...even I felt that.

Ojiro delivered a hard drop kick on Yajin's back causing Yajin to fall to the ground and hold his back for a moment as his teeth gritted and a small rage was released.

Mina - Oh no.

Tokoyami - This is over.

Yajin stood back up and blocked Ojiro and got him in a full nelson and slammed him down as Yajin started to punch him multiple times and delivered one good left hook and he saw Ojiro was out. Sato got up and went for a left hook but Yajin pushed the fist away and performed a small kick combo and a hard right hook that knocked Sato down.

Yajin saw him slowly get up but he couldn't as Yajin took out his mouth guard and spoke.

Yajin - Stay the fuck down.

He put his mouth guard back as he turned his attention to the next target.

Kirishima stood up bleeding from his mouth but he wanted to continue the fight. He rushed at Yajin who easily dodged all his attacks and even pushed him back like if he was nothing.

He turned around and saw Yajin get in a stance and gave him a signal to come at him. Kirishima obliged by running towards him but Yajin took a quick spin and delivered a devastating kick to his face as Yajin let out a yell.

Everyone looked away or gasped from the brutality of the blow. However Yaoyorozu could feel the anger as she felt like she was the cause of this.

Yajin eyes calmed down and he realized what he did but he decided to make it seem like it was part of his lesson.

Yajin - Your movements were sloppy. Control your breathing and be sure to make your body more relaxed so you can move more fluidly.

All three of them were slowly getting up holding either their jaw or nose since they could feel it pretty bruised.

Yajin - Ojiro, your stance is too basic, try to take a more better stance that can help you better. Kirishima. You need to take more martial arts instead of brawling. To help your body be more flexible and faster even with yours hardening. Sato, the same goes for you since both are brawlers then try a new style of fighting.

They all nodded as Ochaco made sure they were okay and soon everyone left. But she stayed as she spoke with Yajin.

Ochaco - Hey. You okay?

Yajin - ....I don't know.

Ochaco - Look you were going way to far with those last attacks. I understand that your training but remember we are your friends. If you have something to talk about you can tell us.

Yajin - I wish it was that simple but you can't help. Look we can talk tomorrow just please...let me be alone for a bit.

Ochaco slowly walked towards the door but before she left, she hugged Yajin as he slowly hugged back with a small tear dripping from his eye.

Ochaco - I'll always be here.

She left as Yajin wiped the tear as the room changed back into a bedroom and Yajin needed to relieve his emotions.

(Outside of the room)

Everyone saw Ochaco leave the room and they asked if he was okay but she said she didn't know but before they could leave Jirou heard music.

Jirou - Guys...He's doing another song.

They all listened in as they weren't ready for the emotion of the song.

[There should be a GIF or video here. Update the app now to see it.]

Hello, hello
Anybody out there?
'Cause I don't hear a sound
Alone, alone
I don't really know where the world is
But I miss it now
I'm out on the edge and I'm screaming my name
Like a fool at the top of my lungs
Sometimes when I close my eyes I pretend I'm alright
But it's never enough
'Cause my echo, echo
Is the only voice coming back
Shadow, shadow
Is the only friend that I have
Listen, listen
I would take a whisper
If that's all you had to give
But it isn't, is it?
You could come and save me
And try to chase the crazy right out of my head
I'm out on the edge and I'm screaming my name
Like a fool at the top of my lungs
Sometimes when I close my eyes I pretend I'm alright
But it's never enough
'Cause my echo, echo
Is the only voice coming back.
Shadow, shadow
Is the only friend that I have
I don't wanna be an island
I just wanna feel alive and
Get to see your face again
I don't wanna be an island
I just wanna feel alive and
Get to see your face again
Once again
Just my echo
My shadow
You're my only friend
And I'm out on the edge and I'm screaming my name
Like a fool at the top of my lungs
Sometimes when I close my eyes I pretend I'm alright
But it's never enough
'Cause my echo, echo
Oh my shadow, shadow
Hello, hello
Anybody out there?

Yajin wiped his tears as he put away his instruments and everyone else wiped their tears as Yaoyorozu, Ochaco and Tsu could feel the sadness and loneliness in his voice.

Yajin laid down on his bed as he turned towards the window and he couldn't hold back his tears as he felt himself just breaking. His mind just went back to his moments with Yaoyorozu but it always switched to Todoroki and her. He had to come to terms that he lost.

Momo Yaoyorozu loves another.
