Stain: I guess I was wrong about you, boy. You're not as greedy or naive as those other children are. You would've became a great hero...

The blade was raised once again.

The killer intent had risen.

Mikoto eyes went wide.

Iida: (Oh-no....)

"If you hadn't cross paths with me."

Stain charged.

Deku: MIICHAN!!!!

The blade striked towards Mikoto who wasn't fast enough to dodge. He waited for the pain to take it's course...

However...He felt nothing...

Mikoto opened his eyes and looked up to his savior.

Shouto: Sorry I'm late Mikoto... Midoriya...Iida...

Mikoto/Deku: Shouto!/Todoroki-kun!

Iida: (What is he doing here?!!)

Shouto had managed to save Mikoto's life by using a wall of ice from his palms.

Mikoto: Shouto...

Shouto:....I'm glad you're alright...You too Midoriya...

Izuku shyly nodded but turned his attention to their paralyzed classmate. Well...They can't really say the same for him...

Shouto: Iida....

Stain: Grrr...Why do brats like you love to keep getting in my way...

Shouto: The Hero Killer...Stain...

Mikoto: Careful Shouto. This man is dangerous. You see his sword. When he stabs you with it. He activates his quirk to parilyzed you once he licks your blood. The same thing happened to Iida-kun and Manual-san...

Shouto: I see...Looks like we won't be leaving this place unharmed then...

Mikoto: Guess not...

Deku: Miichan...?

Mikoto: Izuku...Can you still fight...?

Deku nodded feeling the determination coming back, he gets back on his feet and powers up one-for-all.

Stain didn't wait no longer as three boys teamed up.

Izuku activates Full Cowl and tries to attack the Hero Killer, but Stain slashes at Izuku with his katana, causing Izuku's leg to bleed as Stain licks his katana and activates his Quirk, which immobilized Izuku.

Mikoto: IZUKU!

Deku: Don't focus on me Miichan! Sorry guys! I can't move at the moment! CONTINUE FIGHTING HIM!

Mikoto reclusively nodded before he looks at Shouto.

Shouto looks at him.

Mikoto: Think you can guard me for a little while?

Shouto nodded at his cousin as he begin to use some of his ice powers.

The two had settled on a close range and long range support style of combat. The plan was the best that they could think up of but it was effective nonetheless. It allowed for the both of them to cover as much space with ice and snow as they could to prevent Stain from making any moves that would break any chances of the two winning, it could work for the them.

Stain slashes towards Mikoto who was quick enough to dodge the blade this time.

Solemn breaths escaped from Mikoto's lips as he was launched back by an attack by Stain to relocate back towards Todoroki's position, somehow unharmed as of yet.

He glanced up towards the icy pillars, gaining another idea. Mikoto quickly aims for them to be striked down towards the killer who dodge the attacks leading them to hit the ground.

Iida: NO! JUST STOP YUKIMURA-KUN! TODOROKI-KUN!

Growing irritated, the cousins had enough of Iida pathetic attempts for them to try and keep them from fighting Stain.

Mikoto: IIDA! FOR ONCE IN YOUR LIFE, SHUT THE FUCK UP!!!!

Iida:........

Shouto: IF YOU WANT US TO STOP! THEN STAND UP AND MAKE US!

Iida: O_O

Mikoto: SO STOP ACTING LIKE A COWARD! YOU WANT TO BE A HERO RIGHT?!! THEN STAND UP AND FIGHT!!!!

Shouto: BE THE MAN THAT YOU WANT TO BE!!!

Iida:......(I want to be like my brother...I want to be a hero too...)

Thanks to both Mikoto and Shouto, Tenya begins to break free from Stain's quirk!

Mikoto smirked while raising up his strength of his quirk and boosts up his quirk.

Tenya is ashamed that he needs protection from his friends, Mikoto, Izuku and Shoto.

Iida: I remembers my brother's motivation for being a hero; That helping people is the best motivation for being a Hero.

Mikoto: That's the spirit Iida. You ready to fight?!

Tenya gave a identical smirk.

Iida: Yes.

Shoto begin to attack Stain with a stream of ice concealed in it is fire but Stain dodges.

Stain: You're relying on your quirk too much. That stuff is going to get you killed~!

Stain prepares to cut Shoto with his katana.

However, Tenya intercepts him with his speed and helps Shouto get out of the way. Stain's eyes went wide through the bandages.

Stain: You...How did you...

He then realized his quirk wears off some time ago.

Iida: I agree with you...that I'm a failure as a hero in comparison to the others. But now I have the motivation of not wanting to be outpaced as a hero by Midoriya, Yukimura, Todoroki, and my brother.

Tenya uses Recipro Burst and smashes his leg into Stain's katana, shattering the katana in half and saving Shoto in the process. Tenya then kicks Stain away.

Tenya then looks at the other three...

Iida: I'm sorry you guys for letting you get involved in my problems. I did not want anymore blood to be spilled because of me.

Deku: *Smiles* Don't worry about it, Iida-kun!

Shouto: *Nods*

Mikoto: At least you're back to way you are. Remember, we're all in this together!

Stain the gets up and criticizes Tenya.

Stain: You have a change of heart? A man's character never changes and that you're still is a fake hero who prioritizes selfish desires. Selfish people like you are the "cancer" of society and that he is here to correct that.

Mikoto: Don't listen to him. He's just trying to mess with your head.

Shouto also tells Tenya to pay no heed to Stain. But Tenya says that Stain is correct about him not being a true hero. Tenya tells Stain that he cannot give up so easily as doing so means that Ingenium would die, much to Stain's anger.

Tenya asks Shouto to cool down his leg, but Stain attacks Shouto with daggers to which Tenya intercepts and falls down to the ground. Mikoto finally boosted up his snow, helps Tenya cool down his leg before helping Izuku regains his mobility and activates One For All Full Cowl, jumping off Shouto's ice platform towards Stain.

Tenya uses Recipro Extend and leaps into the air towards Stain. Shoto encourages Mikoto, Izuku, and Tenya to press forward with their attacks.

Shouto: DO IT!

Mikoto: LET'S FUCK HIM UP! SNOW TORNADO!!!

Recently learning a new move thanks to Geysis-Sensei, Mikoto send the small but strong snow tornado towards the wounded killer who gets hit by full on.

Izuku: FULL COWL!!!

Izuku punches Stain in the face with his enhanced might while Tenya hits Stain in the stomach with his speed enhanced kick.

Iida: RECIPRO BURST!!!!

All the attacks had overwhelmed Stain and begin to lose conscious. However, Stain somehow keeps himself awake and makes one last-ditch effort to kill Tenya by attacking Tenya with a blade. However, Mikoto manages to pushed Iida out of the way before blasting the blade right back at Stain and Shouto shoots a stream of fire at Stain's face, burning the Hero Killer's face.

Shouto and Mikoto's additional attacks causes Stain to reach his limit, becoming unconscious and falls onto ice defeated. Shouto and Mikoto created an ice ramp so that Izuku and Tenya can land safely. Izuku and Shouto carefully remove Stain's weapons while Iida and Mikoto tied him up.

Mikoto: (Wow...We did it...we fought a villain and won...Oh boy...The others are going to be jealous about this...)

Deku: Is...everyone okay?

Shouto: Yeah...

Iida: I am alright Midoriya...just barely...

Deku: Miichan?

Mikoto: Yeah...I'm alright...

They managed to beat the hero killer.

Tenya felt a little relived that he avenged his brother's honor but still felt guilty for putting lives at risk.

Mikoto: H-Hey...Iida...Is Manual going to be okay?

Iida looks at the hero who was interning him a while ago...he remembers the man telling him not to persuade himself into going after Stain. But he didn't listen....

Another wave of guilt...

Iida: We should get him to the hospital. Just in case...

Mikoto: Yeah...but first, let me call Geysis-Sensei and tell him-?!

Before he could finish, a piercing screech echoed throughout the city as the four boys looked up in shock.

A large creature with wings was barreling towards them from the sky. Izuku recognized it was the Nomu that attacked him and Gran Torino on the train when they were on their way to Hosu City.

Deku: LOOK OUT!

Before any of them could even dared to move, the Nomu charged at fast speed before grabbing Deku, taking him into the sky.

Mikoto: IZUKU!!!!!!!

Iida/Shouto: MIDORIYA!!!!!

Mikoto barrels himself into the sky using his quirk to try and reach Izuku.

???: I don't think so~~~!

Mikoto: Eh?

Mikoto then felt blow to his back as something attacked him from behind. He then found himself flying in the air before being shoved onto a large building.

An shadowy claw like hand grabbed him by his neck and hoisted him onto the wall.

Mikoto coughed before looking down at this new enemy.

The mop of midnight green hair revealed himself from his hoodie showing a cheshire cat-like grin.

Niko: So we finally meet...Yukimura Mikoto~!
