MHA: A hunter in the world of heroes

As the bell rung, everyone got up and started gathering their stuff. Most of Killua's classmates were in low spirits as their battles were analyzed and their mistakes were pointed out. But that made them all the more determent to improve.

Denki: Hey let's walk together -Kaminari suggested to Killua and the rest whom he spent lunchtime with (Momo Yaoyorozu, Kyoka Jiro, Mina Ashido, Shoto Todoroki, Eijiro Kirishima)-

Momo: Actually, my driver is here, but if you would like we could give you a lift.

Eijiro: We wouldn't want to trouble you

Momo: it's no trouble at all. -She said and she received a few nods-

Killua: Thanks for the offer, but I have to wait for my uncle. -He said while side-eyeing Aizawa who was taking some notes. That action did not escape from Shoto-

Shoto: And I have a few chores to take care of, but thanks.

Momo: Alright, maybe another time then. See you guys tomorrow. -They exchanged goodbyes and the group left leaving Shoto, Killua, and Aizawa alone in the classroom-

Shoto: I didn't know Aizawa-sensei is your uncle.

Killua: Yeah. But that doesn't mean he's pulling any favors for me, on the contrarily he is way tougher and has a lot of expectations for me, I just don't want to disappoint him. -he told Shoto then turned to address his 'uncle'- hey Shota, I'll be waiting for you outside. -After he received a small nod as an indication of a reply, he walked out in the entrance with Shoto beside him-

Shoto: I know you said you don't want to talk about your scars, it's just if Aizawa-sensei is your uncle it's weird he let something like this happen…

Killua: Well... he's not my uncle, not biologically. It's really complicated.

Shoto: I see. You don't have to tell me.

Killua: I know, and I won't at least for now -He said as they got out in the entrance where he saw a familiar pair of blue pigtails- Hey Wendy, wait up.

Killua called out to her and started running in her direction with Shoto following, curiosity was written all over his face. Wendy was taken by surprise she stopped and immediately turned around looking for the voice that called out to her, then she saw familiar silver fluffy hair and a small smile taken over her face. Chestnut brown eyes interlocked with sapphire blue ones.

Wendy: Killua -she said in a small voice, but Killua was a master assassin and was able to hear it. He saw as her eyes drifted from him to Shoto behind him-

Killua: Wendy this is my friend Shoto, Shoto this is Wendy we met in the entrance exam. -he introduced one another-

Wendy: Nice to meet you -she said and bowed-

Shoto: Likewise. -he replied while copping her gesture-

Killua: Seems like you were worried for nothing since you passed the exam.

Wendy: Just barely though… Which class are you guys in?

Killua: 1-A, what about you?

Wendy: Class 1-B. By the way, I wanted to thank you for today, for calming everyone down in the cafeteria.

Killua: No problem… Look, I actually wanted to ask you something. Your surname, Marvell sounded familiar and after some thinking I recognized it. Are you by any chance related to Dr. Grandeeney Marvell?

Wendy: Oh, yeah, she's my mom… how do you know her?

Killua: A few months back I was in the hospital and she was my doctor, I didn't get the chance to say thank you or goodbye, would it be possible to arrange a meeting with her? You know, to express my gratitude.

Wendy: I can ask her, though I am going to need your full name.

Killua: Right, it's Killua Zoldyck.

Wendy: Isn't that the name of the guy who placed first in the entrance exam?

Killua: Guilty as charged. -he said with a flirtatious grin, making Shoto mask a small well knowing smile and Wendy blush a bit-

Shoto: I didn't know you were hospitalized, are you okay now? -He asked him while avoiding Wendy's topic…for now-

Killua: Yeah, it wasn't something major…

Shoto: I barely known you for a week and I already don't believe you.

Killua: Oh, that hurts… I didn't know I was so unreliable.

Shoto: It's not that, I just get the feeling that you tend to ignore your health.

Wendy: Now that you mention it, I remember hearing my mom telling my dad about a kid that run away from the hospital a few months ago. -She said and both looked at him, he just stared back at them, "Is it so damn obvious?" he thought-

Killua: Why are you looking at me? -As mentioned above though, guilty as charged-

Wendy: Well, it was nice talking to you, but I, unfortunately, have to go. Maybe we can eat lunch together tomorrow.

Killua: That would be nice…

Wendy: Great, see you tomorrow then. -she said and started walking away-

Killua: She's more confident than she was in the exam -he said unconsciously out loud while having a small smile-

Shoto: I didn't know your type is this kind of girl, I had thought someone like Yaoyorozu is your type. -Shoto comment making Killua drop his smile and become flustered-

Killua: I have no idea what you're talking about, besides I've seen the way you look at Momo.

Shoto: We're talking about you now… she seems like a nice and sweet girl… the exact opposite of you

Killua: What's that supposed to mean? -he said while flustered, he didn't even bother to mask it-

Shoto: opposites attract each other…

Killua: Oi…

Shoto: Well anyway, I've got to get going, see you tomorrow.

Killua: hay, wait for just a second… -"What just happened?" he thought while looking at Shoto's retreating form.-

A few minutes later he met up with Shota, who just looked at his flustered face and started laughing, saying that under all this tough guy act he was actually a hormonal teenager, making him even more flustered…

Killua: I. DON'T. HAVE. A. CRUSH. ON. WENDY. -he gritted out, but with the way, he was looking it was obvious he was lying-

Shota: Whatever you say, kid, whatever you say.

Killua: I came up with another idea for Himiko… -he said while ignoring Shota- If Himiko goes to prison, nothing will change her addiction, it will only make it worse, which is why I thought that maybe she could work on the prison's infirmary.

Shota: She's going to need a doctor's approval for that…

Killua: Grandeeney Marvell, you may remember her since she was my doctor. She's also Wendy's mom, I asked her to arrange a meeting with her under the excuse of showing my gratitude, you can come with me and talk to her.

Shota: One problem… I was the hero who found you and then lost you, I'm not your authorized guardian… Also, it would be suspicious, don't you think?

Killua: Well… then we could use the papers we made.

Shota: That won't change the fact that I'm not your legal guardian. For that to happen we're going to need to go through court to establish legal guardianship and that's where our biggest problem is… we need information about your past, legal papers and certificates and not just yours but your parents as well, the best option we have is…-he paused a second taking in Killua's facial expression, his eyes were focused on the road and to someone else he could have been thought as unfocused and uninteresting, but Aizawa could see the gears in his head working- adoption… -he finally said and saw as Killua's expression become blank- I don't mind doing it, it's up to you. We could also explain to her that you're a runaway kid with villains as your parents and you're under my protection. I can ask Nezu to help me with all the papers and make it impossible to look like fakes, but that's the only way to avoid court.

Killua sighed and gave a small nod as an agreement to Shota's suggestion. The rest of the ride in Shota's agency was quiet, both thinking about the adoption and what it would mean for both of them.

When they finally arrived, they met Nezu, Midnight, Present Mic, and All Might at the entrance. Midnight and Present Mic eyed Killua and tried to ask Aizawa why he brought him here. Of course, he just ignored them and walked with the rest of them inside the meeting room, where heroes including Hawks, Endeavor, Sir Nighteye, Best Jeanist, and multiple other heroes were sited and were interacting with each other.

In the head of the table was sitting an elderly-looking woman with blonde ash hair in shoulder-length and turquoise eyes. She had a serious-looking expression and was talking with Setchi, who in his turn was as serious as her. She took her eyes off of Setchi and eyed Killua for a moment, she sighed heavily and then continued her talk with the buff blonde male.

Aizawa: Killua -Aizawa called out to him and once he had his attention he pointed into a chair beside another teenager- Go and sit there with Setchi's nephew.

He nodded and headed towards the other boy, as he got closer, he noticed that the boy had a muscular build, he too was wearing the school uniform with the exception of the blazer, he also had blonde hair, the top part of which was arranged in a cowlick, while the bottom section was swept backward. Once Killua was close enough the boy got up and bowed in order to introduce himself.

???: Hello, you must be Aizawa – sensei's nephew, my uncle told me about you. My name is Mirio Togata, is a pleasure to meet you.

Killua: My name is Killua Zoldyck. -he said and bowed as well- the pleasure is all mine, Setchi told me you are a third-year in UA.

Mirio: Indeed, I'm in class 3-B. What about you?

Killua: Class 1-A.

Mirio was about to say something but was interrupted by the elderly woman. The moment she spoke all the conversations were ceased and everyone was sited down. She introduced herself as the Public Safety Commission President, Killua took notice of how she avoided the use of her real name, along with everybody else in the room who used their titles or hero names. The meeting started with a briefing on the case, that lasted at least two and a half hours, during the briefing Killua went through the files he still had and noticed a pattern in Giran's bank account movement, it came from some well-known 'underworlders' that were close associates with Giran, their names were coded but Killua easy cracked the codes since he too used it in his time with Giran. The names that he got were Spinner, Twice and Muscular. He had heard of them before but as individuals.

Suddenly the image of a snake woman came in his mind, he remembered seeing Muscular the day he fought Medusa, he was on her side of the cage, outside holding his phone, at the moment he didn't think much of it just that he was taking a video of the fight. Only to realized that taking video fights was prohibited, and only the Combat Association could take videos so they could later sell them. Therefore, he wasn't filming but video chatting, most possible with the league.

He followed the movement which led to a warehouse just outside of Musutafu. His attention was brought back in the meeting as they proceeded to explain their plan in which they made multiple changes, Killua wanted to tell them his findings and to offer his insight as well but held back.

They were separated into eight units, three-strike forces with ten to fifteen heroes, two medical units, and three informative units. The three strike units would block the underworld's known entrances and had to storm inside and capture as many villains as possible, the informative teams would follow and gather as much information as they could and look for villains that hid, and lastly, the medical teams were supposed to be on alert at all times, in their designated spots, as to reach any of the three places within minutes. Meanwhile, the police had to evacuate the citizens that were close to the 'battle zone', and block the perimeter. After the meeting ended Killua sprinted to Aizawa and told him what they had missed.

Aizawa: And you're sure about that?

Killua: Yeah, Mascular was in Medussa's side appearing like he was filming the fight, but since that's prohibited the only other logical explanation is video chatting.

Aizawa: And since Medussa was with the league…

Killua: Mascular has to be with them as well, he was probably video chatting with Shigaraki or whoever is the mastermind behind their operation. Then there are also, Spinner and Twice. Those two also made huge transactions with Giran.

Aizawa: Most possible league members as well…

Killua: Yeap, we find the warehouse, we find the league

Aizawa: Those transactions happened before we infiltrate Giran, after he disappeared, they could probably have found a new base

Killua: True, but we should still check it out, it could give us clues as to where they are now, or what has happened to your friend.

Aizawa: Oboro… other than he was the first Nomu project, we know nothing. That paper had only information about Oboro and his quirk, along with what a Nomu is… he could be dead…

Killua: From what you told me, he should be dead… Look, I know what I just said is harsh, but you shouldn't have your hopes up. Even if he's alive, he probably doesn't remember the life before being Nomu, and I highly doubt he has full control over his actions let alone free will.

Aizawa: I know… anyway I'll form a small team to go check it out.

Killua: Maybe the two of us can go…

Aizawa: Killua…

Killua: We could take permission from Nezu, he knows my skills, besides we need infiltration skills and both of us know that the two of us are the experts in this department…

Aizawa: Fine… I'll talk to Nezu, but if they are there you stay out of the way and we call backup, once they come you disappear as you were never with me. Understood?

Killua: Yes sir!! -Killua said while he gave a salute like he was a soldier, something that actually disturbed Shota since Killua was at some point some kind of soldier-

͛֎͛

Just like the first time they infiltrated together, they blend in with the shadows and the darkness of the night. Despite being only the second time, they worked together they both worked in perfect harmony.

They got in the warehouse by car, they stopped many miles away and from then they used Killua's godspeed to reach their destination, once they did they got inside through one of the windows from the second floor and moved without making any noise, they found clues that indicated that at some point the league was indeed there but not anymore. They left their guard down but not completely after all they were still in enemy territory. They continued looking for clues that could indicate their new whereabouts or the rest of their members but found nothing.

Killua: You smell that? -Killua asked in a hushed tone. They were now on the third floor where Killua picked the scent of rotten flesh. A scent he was overly familiar with-

Aizawa: Yes… Do you think they could have a Nomu lab here? -He asked while looking for a clue that could tell them where the smell came from-

Killua: Maybe… -he said, as he finally took notice of the marks on the floor. Marks that indicated something heavy being pulled, he looked up at the library and smirked "Cliché much?" he thought as he scanned the library for a way to open it. His eyes landed to a small globe that had the least dust and pressed it. –

A clicked sound echoed the room gaining Aizawa's attention. He saw as the library came forwards and Killua put it open. The smell of rotten flesh became even stronger as it infiltrated their senses, making Aizawa gag and grimaced in disgust. He pulled his shirt a little bit and covered his nose trying to stop the smell from entering. Keyword trying. He followed Killua into the room.

What he saw made him freeze not from fear but from the gruesome sight. Multiple bodies of all ages and gender, mostly being younger males, skin white, blue lips and nails, blank eyes filled with fear, and most importantly multiple cuts and stubs all over their bodies. It was a gruesome sight, the room was filled with blood, and worst of all there were straws everywhere, all around the room. Giving a clue as to who was behind these murders.

Aizawa: Do you still think you can save her?

Killua: It wasn't too late for me…maybe it's not for her…

Aizawa: I'm not so sure about that kid, you're a master assassin I'm sure you can see it. There is too much joy and pleasure in these kills, even if your plan works and we manage to stabilize Toga's addiction to blood, she will still be addicted to murder…

Killua: I know… -he said while he was standing above a body, he knew from reading Toga's file. Ichika Toga. Himiko's mother- it's too late, she's too deep into her madness, but we could at least try and stop her addiction before it gets even worse.

Aizawa: How much worse can it get? She already killed her parents… I suppose we could try, but she's already too out of it… just like you said we can't have our hopes up.
