Maelstrom

A Naruto x My Hero Crossover

Chapter 1: Prolouge

The underground hideout had been shaking for the last half-hour, or at least that's how long Naruto thought it had. He had lost track of how long he had been there captured by these Yakuza. Letting out a sigh as he recalled the rather unfortunate circumstances that he had been in since he arrived here.

Flashback

Naruto let out a low groan as he slowly came back to consciousness. He still felt quite battered, though that was to be expected from his long and brutal fight against Pain. What met his vision wasn't the standard material of the tents that he expected or the open sky but dull gray metal. Rising up he saw several other plain beds and cabinets that he assumed must contain medical equipment.

"Ah you're awake." A voice called out. Turning Naruto came face to face with perhaps the weirdly dressed person he had ever met. A long white coat covered most of the man, though a brown and gold bird mask poked through the hole of the hood. There clothes waiting for you. Follow me when you're dressed." The man left before Naruto could ask where he was.

'Rude' Naruto thought as he dressed in the plain shirt and sweatpants. Not seeing any of his gear or even his headband he walked out to see the man waiting for him.

"Good. Follow me." With that the man started walking, no doubt expecting Naruto to follow. Seeing no other option, he followed while noting that they must be underground. The lack of windows and stale air reminded him of some of the underground bases he and Jiriaya had come across during his training trip. The thought of his old mentor cased a pang of grief to pause his movements. He quickly shook off the memories and continued following the man.

Something was definably wrong here. The more Naruto followed the man the surer was that these people were not good. It only got worse when he noticed more masked people seemed to be following them while surrounding him at the same time. Having no idea who these people were or their combat abilities he followed for the moment. They finally came upon a door much fancier than the others before he was led in.

"We brought him Overhaul-san" Instantly Naruto knew that the man in front of him was anything but good. The ones that had followed them must have noticed him about to attack, for in an instant Naruto felt like he was slowing down while everyone continued to move at a normal pace. Straining he looked back to the while-coated one to see that he was being pierced by something coming from his head. Before he had time to ponder, he was blasted off his feet into the ground by one of the larger ones. Roughly pulled up into a kneeling position he struggled against his captors.

"You sure he doesn't have a quirk? Kid's pretty damn strong!" Shouted one of the men restraining him. Naruto's struggles ceased when a wave of vertigo came over him. Before he knew it he had been clapped in irons that were more blocks of metal than anything.

"Now then." Their apparent leader said as he leaned back in his chair "I have questions that you will answer."

Naruto snarled in response as he continued to struggle before another hit to his back took the breath out of him. Unfortunately, it was the beginning of a rather long questioning.

Flashback

Naruto became lucid again as he registered that he was on the cold hard ground in a small room, with a toilet in one corner and nothing else. Groaning as he sat up he wasn't surprised to see that his captors has restrained him pretty heavily. Luckily whatever these Quirk suppressing cuffs were supposed to do didn't affect his chakra.

He shook in rage as he remembered the questioning he had been subjected to. For some reason he couldn't lie at all, and had revealed things about Konoha that he would never give enemies! What truly confounded him was that for the most parts these Yakuza seemed more confused the more questions he answered

What was his quirk? He responded 'What's a quirk?' and more questions that were apparently common knowledge. At least to people wherever the hell he had ended up from the masked Akatsuki and Kakashi's sharigan techniques colliding. Taking a deep breath, he registered crying coming the doorway in front of him. Knowing that it couldn't be any of the men since it was a little girl, he knocked on the door. A gasp of fear greeted him before he heard the small shuffle of feet before the door opened. He was greeted be a small girl with blueish, off-white hair. A simple gown covered most of her body, but numerous bandages, more than any child should have, covered the parts that the gown didn't cover.

"W-who are you?" The girl timidly asked. Knowing that she was just as much of a prisoner as he was Naruto gave a soft smile as he introduced himself. The girl, Eri as she introduced himself, Made Naruto give another of his famous promises.

He would get them both out of this hellhole.

Flashback

"I should kill you" Overhaul stated as he stood over Naruto. Despite taking out most of the guards that had been assigned to watch over him and Eri he had failed when trying to protect Eri from the attacks from the man looming over him. Eri had already been taken from him and was being restrained with total fear in her eyes.

"Fortunately for you I need you alive for my research, though not whole like Eri." Sudenly a hand gripped his arm before it ceased to exist. Letting out a scream of pure pain he knew that his was supposed to break him.

Unfortunately for Overhaul Naruto resolve only hardened into pure steel.

Flashback

"Hi there!" Came the greeting form the twin-bunned blonde that had entered the room. She must be one of the new people that the Yakuza had been trying to recruit. Being strapped to one of Overhauls experiment table he couldn't really do anything other than appraise the girl approaching him. Like most of the clothing he had seen in this world he was sure that it was appropriate for her age. On top of the uniform was what he assumed equipment that had something to do with her quirk.

"Can I have some of your blood?"

Which apparently was blood-related.

"As long as you don't kill me." Naruto sighed. There wasn't much he could do at the moment. The girl paused for a second, as if actually surprised he offered, before her confusion evolved into a full-blown grin. Taking one of the needles form her equipment she stabbed his thigh, draining affair amount. Honestly, she reminded him on Anko a little. Well maybe it was just that their first interaction had to do with the woman consuming his blood.

A rather sexual moan rather abruptly brought Naruto out of his memories as the girl straddled him. Were it any other situation he would have reacted, but he was restraining himself.

"My name's Toga! What's yours' newest bestie?"

Thus began one of the weirdest friendships Naruto had become a part of.

End Flashbacks

Another tremor brought Naruto out of his memories. Knowing that Eri was more than likely being taken by Overhaul should the hideout be compromised he started to channel Chakra. He had already broken heavier bonds than these after all

'I'm coming Eri. Just hold on.'
