Legend:

"Talking."

'Thinking...'

Prologue: Problem Children

Between all the times that his quirk decided to stop working, this wasn't a good moment.

Those damn quirk destroying bullets had hit him and his quirk, for strong that it is, now it is out of the picture for some hours. And those hours can decide if they make it or not.

He felt a real bullet graze his cheek and blood started to pour from the wound. His grip on Izumi and Eri tightened as he took a turn into another alleyway as more bullets came flying past them.

He felt two pair of arms hug his neck and felt Eri whimper on his shoulder "I'm scared..."

Izuku looked at her with his blood-red eyes and gave her a smile with all his sharp teeth. "Don't worry Eri... the three of us, are going to get away from them... and never going back." he felt a bullet pierce his tight making him growl of pain. But somehow, managed to keep running.

"You're hurt!" Izumi exclaimed as Izuku breath became shallower.

"Don't worry Izumi, as long you two are good, nothing will stop me." he went to a closed door, and with one good kick, opened it and got in.

He closed the door and blocked with some nearby furniture. His green-blackish hair covering one of his eyes, as he scanned the place. It looked like some sort of theater.

'The roof... we can escape across those...' Izuku thought as started to limp up the stairs, Eri and Izumi on his back. They could hear the screams and the door being smashed. They got to the fire exit in the rooftop, and Izuku fell to his knees. The multiple wounds in his body were starting to take a toll on his body.

"Big brother!" Izumi and Eri screamed as Izuku sight became blurred.

They got in front of him as Izuku panted. He hugged the both of them as tears came into the kids eyes. "I'm sorry... I won't be able to go with you..."

"B-But, you promised that..." Izumi sobbed and Eri nodded.

"Y-You were coming with us! We-We were getting a home in the woods! Like in the story!" Izuku chuckled as he broke the hug.

"Izumi... keep both of you safe... look for a hero... they will keep you safe." Izuku said as the sounds of steps were approaching. "Now go..."

"B-But..." Eri said and one tired look from her brother made tears go to her eyes. Izumi balled his fists and grabbed Eri's arm and dragged the screaming girl down the fire ladder.

Izuku somehow managed to stand up and from his pants took out both of his guns. He only had one clip for each, and there are at least 20 guys.

He glared at the door that was broken. "Showtime."

*With Eri and Izumi*

Izumi never ran so fast.

He still had a grip on Eri's arm as he ran with her still crying. Big bro will be fine! He is always fine, there is no one stronger than him!

His thoughts were interrupted when some bandages grabbed his waist and stopped in his tracks. Both, his and Eri's eyes were widened. Where they caught!?

"Brats... where are your parents?" A gruff tired voice asked them and both kids looked at a man dressed completely in black, yellow goggles, a white scarf and black hair.

Izumi panicked and was going to do something, but Eri recognized him as a hero her Big Brother studied. She didn't remember his name, but she knew who he is.

"Our brother needs help!" She exclaimed and the hero nodded.

"Where is he?"

She pointed to a rooftop but Izumi put her behind him "W-Who are you!?" He demanded and the hero sighed.

"Stay here while I go after your brother." He ordered and Izumi glared at him but Eri tugged his arm.

"He is good..." She mumbled and Izumi was going to answer but the hero was already gone.

*With Izuku*

Izuku fell against a wall, as both of his arm limped at his side. He had wounds on his abdomen, torso, face, head, arms and legs. And somehow, his quirk came back in time to save him. Well, at least part of it.

While his regeneration was still off, he still can use his strength and reflexes. And once the bloodrush came, the Yakuza's time was over.

But he ran out of strength and energy as usual whenever he went into bloodrush. He felt tired. More than ever. He just wanted to sleep...

He saw someone land in front of him. He didn't have the strength to rise up or fight back. So he just followed what his body told him and closed his eyes.

*UA*

"Is he still asleep?" Aizawa asked to Recovery Girl that sighed.

"Yes. His wounds are healing almost by themselves at a great speed. He is only unconscious out tiredness right now, but he should wake up soon." She then glared at the pro-hero. "But why did you take so long!? When you brought the boy here, he was about to go! Do you at least know what happened to him!?"

"From the bodies on the rooftop, I would assume he was in a fight. And before that, in a chase for what the two brats said before."

Recovery Girl nodded "Hmmm... I wonder from who they are running... I examined the boy and he had a chip on his neck. Don't worry, the chip is gone now."

"And I thank you for that..." They turned their heads to see Izuku leaning against the wall with an arm, breathing between pants. "But now, I want to know where Eri and Izumi are..." His red eyes glared at the heroes.

Aizawa was about to activate his quirk, no doubt alerting the boy, but luckily, Recovery Girl was there. "Now, now; they are fine with director Nedzu. I'll call them to come and see you, but you still need to rest."

Izuku growled and glared at the old woman. He could smell again and simply walked past both heroes and decided to fetch his siblings by himself.

He caught Aizawa's scarf and glared at the man that glared back. But before anyone could do anything, two blurs hugged Izuku's waist.

"Big Brother!/Big Bro!"

Izuku blinked first, his instincts still slow, before his face broke into a relieved smile "Eri! Izumi!" He exclaimed as he hugged them. "I told you two we would be fine."

"And indeed you are!" A hight-pitched voice exclaimed and Izuku smell an animal. He looked down to see one in a suit and in red shoes. "Hello! You are probably wondering what I am. A dog? A rat? A bear? Well, I am UA director, Nedzu!"

Izuku raised a brow but said nothing. "Now, would you like a cup of tea while we discuss the terms of your stay in UA? Not to brag, but I was told I make an excele-"

"Wait? Stay in UA?" Izuku asked and Nedzu nodded.

"That's right! The three of you will stay in UA, you as a student! You are lucky classes starts next week, otherwise we would be in a problem." Nedzu chuckled and Izuku glared.

"What do you win? I doubt you are doing this out of good will."

Nedzu chuckled "Well, the only thing I wish is to save three young kids from the claws of evil! And what do I win, you ask? Well, for starters, you can help us by giving us information on the villains that were chasing you and I will get a future hero. See? We all win!"

Izuku glare softened and looked at both kids. Eri was beaming, nodding her head, approving the idea, While Izumi, much more silent about it, also nodded.

With a sigh, Izuku nodded.

"Excellent! Now, Recovery Girl will treat your wounds, while I'll show this two their new home! Oh! And before I forget, what's your quirk and who were the people behind you?" Nedzu asked and Izuku looked over his shoulder as he sat down.

"My quirk is called 'Blood-Thirst' and they were Yakuza..." He informed and Aizawa raised a brow.

"Yakuza? Why would the Yakuza be after you three?"

Izuku shrugged "That for later. I still feel tired from before."

Nedzu chuckled "Well, you two will have time to know each other! We will talk more whenever you feel better, Young Midoriya." Izuku stopped in his tracks and turned to the director with wide eyes.

"How did you..."

Nedzu chuckled "Your mother had been really worried. But don't worry, you'll see her again."
