Aizawa (now wearing his hero costume that made him look like a hobo with a scarf) and both Midoriyas entered a police station, which made Izuku sweat at thinking that Mr. Aizawa lied to him. It was chaos in the station, police officers doing their job and running around in a hurry.
"Don't worry, kid, we're not throwing you in jail," Shouta promised as he led them into the back to a police interrogation room, on the side where you can look in. Inside the room was the chimera of UA and a detective wearing a beige coat and having black hair, sitting down and enjoying a cup of hot tea.
"Is that Nedzu, the principal of UA?!" Izuku gushed, bowing reverently. "Your quirk is so cool! You're, like, the smartest being on Earth!"
"Why, thank you, Mr. Midoriya! Am I a dog, a mouse, a bear? More importantly you're right!" Nedzu clapped lightly.
"Aren't you a stout?" Midoriya asked. "I mean, you resemble one at least."
"You're mostly correct, young man! But onto the reason why you're here," the chimera expertly changed the conversation, "Mrs. Midoriya, since you're Mr. Midoriya's guardian you must be here at all times, which I'm sure you don't mind."
"I don't, Mr. Nedzu," his mother answered, a resolute look on her face.
"Please, let's not allow formality get in the way of talking. Just call me Nedzu, please."
"In that case just call me Tsukauchi, or Detective, if you will," the black-haired man spoke up.
"Can we get to the point already?" Aizawa gruffly asked.
"Fine fine, Aizawa is right. Mr. Midoriya, you have an overpowered quirk in your arsenal, don't you?" the chimera asked, leaning forward in his chair. "A quirk that can make you the most powerful person in the world if used for villainy. I, however, heard you want to become a hero. Is that correct?"
"Yes, sir. All my life I wanted to be a hero like…All Might, or perhaps Eraserhead."
Aizawa's eyes widened marginally, not expecting being the idol for this kid.
"I always knew it'd be an impossibility for me to become one, due to thinking I didn't have a quirk, but now…"
"Now you have one," Tsukauchi finished for him, "and you're scared that you're destined to be a villain, aren't you?"
Midoriya nodded forlornly.
"Well worry no longer, Mr. Midoriya!" Nedzu told him, a smile on his face. "Once you return the quirks you stole, we can begin training you!"
"Uh, Nedzu, the kid has a form of quirk madness," Aizawa butted in.
"I beg your pardon?"
"My quirk, All for One, tells me to do things, to steal quirks from others. It's kinda screaming in my head right now to get away and steal more quirks," Midoriya admitted, wanting some caffeine to quell some of the voice.
"My, how fascinating. And also horrifying. Are you saying that you only committed vigilantism due to your quirk pestering you?" Nedzu inquired.
"Pestering is such a soft word, but yes, I never would have used my quirk if I didn't have to."
"How have you managed it?" the chimera questioned.
"With coffee."
"Ah, I see that the caffeine in coffee quiets the voices. Tsukauchi, call someone in to get this young man a coffee," the principal of UA asked his detective friend, who began to send out a text message to one of the orderlies. "How do you want your coffee, Mr. Midoriya?"
"I just drink it black, but I don't really like it that way," Izuku told him. Nedzu nodded and whispered to Tsukauchi something. The latter nodded and put in the request, and within two minutes a young lady wearing a police uniform came in with the coffee. It smelled fragrant and delicious, unlike every other time Midoriya had it. He took it from her gratefully and sipped it, finding that it tasted divine and, most importantly, quieted the voices.
"That coffee has milk, sugar, honey, and chocolate syrup in it. Now with it, and hopefully a clearer mind, are you, Mr. Midoriya, willing to give back the quirks to those villains?" he asked, his pleasant smile never wavering.
"Absolutely."
"That's my baby boy," his mother cooed, reaching over and pinching his cheeks.
"Mom!" he protested, smiling fondly.
"Well, let's get this underway, shall we?"
Midoriya entered the interrogation room and saw a man restrained to a metal chair. He had earmuffs on playing music, a blindfold on, a pair of quirk-suppressing cuffs, and a gag preventing from speaking. He looked to be the man that tried to asphyxiate Izuku when he was in his sludge form.
Ignoring the voices in his head he reached out and touched the back of the man's neck, pushing Sludge back into his body. All for One was yelling at him, screaming at him about why would he do that. Izuku winced at the intensity of its anger as he left the room. He navigated his way back to his mother, Aizawa, Nedzu, and Detective Tsukauchi, all of whom were looking suitably impressed and happy.
"Mr. Midoriya, I'm proud that you managed to overcome your quirk madness and returned the villain's quirk. You have passed the test," Nedzu congratulated.
"Yeah, good job, kid," Aizawa agreed, nodding with a slight smile. "All Might was definitely wrong about you."
"Of course he was. My darling son is not a villain," Inko reiterated.
"Of course he's not. A little misguided maybe but certainly not a villain. I'll be having words with the man later," Nedzu promised with a frown. "Now, time to return the other two quirks you stole."
"Other two? Don't you mean four?" Midoriya corrected, confused.
"Four? You stole an extra two? When did you do this?" Shouta questioned, not mad at the kid and more concerned for the extra two men and/or women who were missing quirks.
"Well, earlier this week at night I was looking for candidates for All for One when I spotted a Caucasian man wearing homeless attire calling me down an alleyway in the red light district."
"Baby, didn't I tell you not to ever enter the red light district, especially at night?" Inko asked, looking concerned for her precious baby.
"Sorry, Mom, I couldn't help myself," he apologized, hugging his mother tightly. They disentangled themselves as he then said, "Continuing the story, after an…altercation, I stole the homeless man's quirk and a corpse's quirk that was nearby," Izuku explained.
"You can steal from corpses?" Nedzu asked, very much intrigued by this development.
"Apparently so," Midoriya shrugged.
"What were the quirks, sweetie?" his mother asked.
"I named them, uh, Metal Knuckles and Cracked Eyes. The former reinforced my knuckles with a metal, now being silver," he demonstrated by activating the quirk by pulling on it. They all appraised it with a nod. He then wiped the concealer off around his eyes, semi-shocking the individuals in the room by the cracks sprouting on his face. "And Cracked Eyes let's me see in the dark like a dark elf, while also making me have cracks coming from my eyes."
"Well we have to return the quirk to the homeless man, but finding him will be an issue. For now keep it," Aizawa instructed, surprising the young man.
"You're going to let me keep two quirks?" he asked in an awed voice, not expecting them to trust him with it.
"Why of course! How can you be a hero without using your quirk?" Nedzu asked.
"But…that would mean taking quirks!" Izuku protested. "Isn't that wrong? Illegal?"
"Wrong, maybe. Illegal? Not at all, Mr. Midoriya," the detective spoke up. "Taking quirks and giving them to someone else is unthinkable, so it was never written in the books as being a crime. We, legally, cannot arrest you for keeping those two for now. But as a show of trust you need to return the other two."
Izuku nodded as he then left the room and went back into the interrogation room, being instructed that this man had the quirk Mimicry. After a slight back and forth to figure out that it was Inanimate Possession that he was calling it, he returned it easily to the restrained man.
He then repeated the process with another restrained man, returning the mystery quirk that was called Adamantium Skeleton (which sounded really cool to him).
When he returned all the adults in the room were beaming, clearly impressed and happy that he could control his urges and the voices in his head. "My my my! You have the potential to be the most powerful person in the world and you gave it up just like that? I'm convinced, are you, Aizawa?"
"I am, Nedzu. This kid has potential."
"Does that mean my baby isn't going to jail?" Inko asked hopefully.
"Jail? For vigilantism?" the chimera asked, getting a nod from both mother and child. Nedzu shook his head no, a smile on his face. "Your son is not in any legal trouble anymore. Imagine, if you will, it being swept under the rug. Now, however, we need to train your son to become a hero before the day of the UA Entrance Exams arrive, which is in ten months."
"I'll be overseeing your son's training but I'll need to set some ground rules first. Rule number one," Aizawa looked Midoriya in the eye, "no more stealing quirks unless you're in a life or death scenario, got that?"
"Okay, but what about the voices in my head?" Izuku asked, wanting to follow the rules but his quirk was telling him to not.
"We're going to prescribe you some antipsychotics, Mr. Midoriya, under the orders of Recovery Girl."
"Sweet, any more rules, Aizawa-sensei?"
"Don't be a slacker. What's worse than a competent villain?" he asked, quizzing his new protégé.
"An incompetent ally?" the younger Midoriya answered hesitantly.
"Exactly. I will be the arbiter of whether or not you become a hero, Midoriya, and I will not have you slink by and become a half-assed hero, do you understand?"
Izuku swallowed thickly as he nodded, "Yes, sir!"
"Good, training starts tomorrow."
"Wooh! That was a good run!" Midoriya cheered, all sweaty and energetic from the exercise Aizawa-sensei gave him. They were currently at a private gym, usually reserved for elites and pro heroes. The room was empty at this time of day, thankfully, as he and Aizawa went through a plethora of activities, such as weight lifting and the like. His mentor was nearby, getting off the treadmill as he chugged some water before passing it to his protégé, who took it gratefully.
"I'm surprised you were able to do five miles like it was nothing," Shouta commentated.
"I'm in shape because of all of Kacchan's bullying," the younger man answered. After getting a probing look from his mentor he continued, "He's my childhood best friend, or he used to be, at least."
"Let me guess: He bullies you because he thinks you're quirkless?"
"Yep," he answered with nonchalance, as if it didn't bother him (it did). "So what should we do next?" Izuku asked Eraserhead (when he found out his mind was blown), and was led to a boxing ring. The two got into the ring, putting on safety equipment such as bandages and boxing gloves.
"Now is the time where I teach you how to take a punch," Aizawa told his protégé. "I'm going to punch you, slowly, and I want you to react to the hit as normally as possible; whatever comes through your mind."
"Okay, Aizawa-sensei. Lay it on me."
Shouta threw a slow punch at the right shoulder of Izuku, the greenette moving with the punch. "Okay, you seem to understand how to lessen the damage of the punch somewhat, let's continue."
"Why are we at a morgue, sir?" Midoriya asked as they got passed oddly high security.
"You said yourself that you can take quirks from corpses, right?" Aizawa questioned as they entered room filled with cadaver storage. The older man sent away the young orderlie who was monitoring the place. Eraserhead went to the highlighted pull-out storage units and pulled them out, showing the dead bodies.
"Oh my god! Is that Crust, the number seven pro hero?! And Master Driller?!" Izuku asked, guffawed at seeing two pro heroes who were ranked high on the top one hundred pros of Japan.
"You know your heroes. Great," Aizawa drawled out, crossing his arms. "Yes, these are the deceased pro heroes Crust and Master Driller. They simultaneously died in a villain attack against the yakuza."
"And you want me to…" Midoriya trailed off, gesturing to his hands. Eraserhead raised an eyebrow, secretly amused and wanting to fuck with the young lad. "You know…the thing?"
"What thing?" Aizawa pressed, wanting him to grow comfortable with saying what his quirk does.
"Fine…do you want me to steal their quirks?" he relented, pouting.
"Steal is such a strong word; try using take," Shouta suggested. "Unless of course you're actually taking quirks from heroes/villains, that would be stealing," he tacked on. He cleared his throat, "Take their quirks, Midoriya, they don't need it now, do they?"
Izuku gulped and with an excited reach (because of his quirk whispering to him that this was a good outcome), he grabbed both deceased heroes with separate hands and immediately visualized their quirks, soon to decay and die just like its owners. He took it and felt it slot into place within his own body, the first (Crust's) was white as a hospital, while the other (Master Driller's) was silver, like a metal. "I have them, sir."
"Just like that?"
"Just like that, Aizawa-sensei. Taking a quirk is as easy as touching them and stealing—I mean taking, taking it only takes a second," Izuku answered. "I could take your quirk or give you one in a second, sir, all I need is a second of contact," he kept on repeating, not noticing he used the same words three different times in two sentences.
Aizawa thankfully didn't shiver at the scary sentence, instead giving a small smirk. "Only you, problem child."
"You gave him more quirks?!" All Might strode through the door, his steps cracking the ground lightly as he slammed the door shut, the door shaking on its hinges. "What the hell is wrong with you?!" the number one pro hero shouted, in casual clothing.
"Good evening to you too, Yagi," Nedzu calmly answered as he finished his sip of tea, turning off the display on his monitor. "I thought it was a good idea, at least."
"His quirk is—" All Might, in a sense of wisdom, lowered his voice a couple of octaves to not tell the world his secrets, "His quirk is exactly the same as All for One!" he fiercely whisper-shouted. "We had him in our grasps before he became a serious threat, and you let him go with Aizawa?!"
"That was exactly the plan if Mr. Midoriya didn't want to go with you," Nedzu reminded while whispering also, to match the blond man's energy.
"Who cares if he doesn't want to come with me?! He's an international threat!"
"His mother, for one, doesn't want her 'baby boy' to get kidnapped by the number one pro hero," the chimera pointed out. He paused, taking a sip of his freshly brewed tea to not only have a dramatic effect, but also to piss off his pissed off friend even more. "And two, the original was a threat, not the young man," Nedzu corrected, waiting for the inevitable pushback.
"But he has a form or a complete copy of All for One, Nedzu! Being anywhere except the watchful eyes of myself would be disastrous! And look at him now, galviating across UA's gym and testing out his stolen quirks on Aizawa!" he argued while continuing to whisper-shout.
"How'd you figure that out?" Nedzu asked as he turned on the monitor to show the live feed of Midoriya and Aizawa half training and half having a good time, the former using his quirks in great conjunction, the other sometimes turning off the other's quirk; it looked fun and educational, and some, such as the chimera, watched with a fond expression. The other, not so much.
"I went here to talk to Aizawa on the status of the criminal and was told by Present Mic that he was in Gym Alpha. I go in there and I see this?" All Might pointed at a specific scene of their spar. "Makes my heart want to drop! He's combining quirks just like he's done every time we've had him where we wanted!"
Nedzu gave an unimpressed look, putting down his tea cup on his desk. "Yagi, All for One and Mr. Midoriya are two different people. And we cleared him of all charges, so he's not a 'criminal,' like you've called him."
"For now, at least," All Might bit out, a sour look on his face. "We need to arrest and confine him, not give him even more quirks and train him."
"He's a human being, Yagi. A young teenager with an overpowered quirk that wants to be a hero," the chimera reminded.
"The criminal is a villain!" the blond insisted, "He has the most dangerous quirk in existence and should be locked up, the key thrown away—!"
"Enough!" Nedzu raised his voice, stopping his friend. "You're acting irrational, All Might. The young man wants to be a hero, plain and simple. Sure, he has the most dangerous and most overpowered quirk known to man, but that means we need to guide him, nurture him better than ever from the side of villainy! He's not a villain, and he'll never become one as long as we show him it's better to be a hero than a villain," the principal calmly explained. "Do you have anything else to contribute?"
"Hmph!" the blond pro huffed out before leaving the room, going somewhere (presumably to watch Aizawa's and Midoriya's spar).
