Two days they were passed after various incidents occurred that night. News pages are still filled with news of the capture of the hero killer Stain by the No. 2 Hero Endeavor. Although there was also news about the appearance of Nomu, it was all buried due to the fame of the hero killer. There is also talk about Stain's ties to the villain league which has recently become a hot topic.

At the same time as the news spread, a video containing the ideology of the hero killer was secretly spread on the internet. The video quickly spread and many people were influenced by its ideology and some even followed it.

Izuku also watched the news in his office half-heartedly. He wasn't too interested in the stories shared on the internet although he had to admit the videos he saw had enough power to move people. Whether it is for good or bad there is a possibility that this might cause ripples in society. Izuku just thought this would probably pass like it was.

Even though he was also involved in the incident, there was no news about him. This of course happened since Izuku asked the police not to reveal his along with Shoto and Iida's involvement, and turned all attention to the No. 2 hero Endevor since he also came to catch the hero killer in the first place.

No longer interested in the news broadcasting on his computer, Izuku turned his attention back to the documents in his hands.

Since the police asked for the Dawn guild's cooperation regarding the appearance of monsters in that incident, they sent information regarding the development of the case the day after. The information contained developments in the case and new details they discovered, it also included information about the two people he saw that day.

From the information he read, there were several other findings on the bodies of the Nomu he killed that day. Not only was there some monster DNA but also a crystal was found embedded in his chest. When he read this, Izuku couldn't help but furrow his eyes especially when he saw the photo of the crystal that was sent that only confirmed his suspicions.

Finished with additional information he then looked at the profiles of the people he saw at that time. The man with grayish blue hair that he saw at that time had the name Shigaraki Tomura with quirk decay while the other black mist man was Kurogiri who had the warp gate quirk. They both made their debut as villains when they attacked UA students.

It was quite unusual for a novice villain to attack a place like the UA facility. Moreover, with the number of people attacking, it seemed impossible to sneak in without being detected.

Sensing something strange, Izuku could only assume that there was another force helping them. And he was sure that whoever was behind the attack, must also be related to the appearance of the Nomu and chimera Nomu that he killed at that time.

Whatever it is, it's Tsukauchi's job with the police to uncover it. Meanwhile, his task was to investigate the flow of distribution of monster corpses and mana stones from illegal dungeons that might escape their supervision and that of the Hunter Bureau.

Thanks to the information network his guild had he got some useful information. From the information he received, several wild dungeons appeared that were not recorded by either the Hunter Bureau or the other guilds. Apart from that, there are also illegal activities of hunters who are not registered with any guild.

Even though many guilds have been established, there are still some hunters who do not join the existing guilds. Most of these people were people who had side jobs or worked as association raid hunters.

Seeing this information, Izuku knew that he needed to track these people down and track down where the loot from these wild gates was being sold.

After organizing his thoughts, he then contacted his information network to investigate this matter.

After finishing his work, Izuku took a deep breath. And while he was relaxing his cell phone suddenly rang. Izuku immediately picked it up when he saw Shoto's name appear on his screen.

" Hello Shoto-kun, what's wrong? You don't usually call me. "

" Nothing in particular, just.. are you busy today? "

" Not really, what's wrong? "

" I see, Iida asked to meet you, it's like he wants to thank you or something, is that okay? "

" Sure, I think I can "

" Okay, I'll tell Iida. "

" Ah right, if Iida-kun has something you want to ask, you can give him my number. "

" Is that okay? "

" It alright "

" Okay, I'll give it to him "

" Sure, let him know, I'll wait for him to contact me. "

" Of course "

After finishing his work that day, Izuku then went to a family restaurant in Tokyo. The reason he was there was none other than to fulfill an invitation from the Iida family conveyed by their second son.

Izuku stood for a moment looking around the restaurant before finally entering. When he arrived, he was immediately greeted by the waiter who was waiting for him and immediately took him to the room he had booked.

The waiter then opened the door and invited Izuku to enter. There he could see several people who were waiting for him. Seeing Izuku's arrival they immediately got up and greeted him.

" You have come, please have a sit "

The first person to greet him was a man who looked to be in his 40s and bore a resemblance to Iida. Beside him, there was a woman with short blue hair glasses and Iida, and another person who looked like him but was older.

Izuku just nodded and sat in the chair that had been provided for him.

" Thank you for inviting me Iida-san "

" No problem, this is what our son's savior should do. "

" I see, then... "

Izuku then looked at Iida and the young man beside him. The young man then nodded in confirmation and Izuku couldn't help but smile in relief.

" We heard it from Tenya. Thanks to you, we not only saved Tenya but also Tensei. Even though we almost lost hope, thanks to the medicine you gave us, our son finally recovered and was able to walk as before.

Once again, thank you "

"" Thank You ""

The entire Iida family immediately stood up and bowed to Izuku following the head of the family. Izuku, who saw this, could only smile and ask them to sit down again.

" It doesn't matter, I just did what I should do. "

Izuku was still smiling while Iida's family looked at him in surprise. For just that reason Izuku handed over the precious medicine to their son. Even though they had heard the old story that Izuku told their second son, it was still hard to believe.

There was silence for a moment before Mrs. Iida finally started the conversation again. They started talking about topics like work and so on. Thanks to her, the atmosphere became livelier again and dinner that day went smoothly.

Izuku also enjoyed his time with Iida's family, but dinner had to end soon since Izuku received a call from Tsukauchi. Therefore, Izuku went to the balcony and immediately accepted the call. While making sure there was no one around, Izuku also put up a mana barrier around him to prevent anyone from hearing his conversation with Tsukauchi.

" Hello Tsukauchi-san? "

" Hello Izuku, have you seen the information I sent you? "

" Yes, I've seen it "

" what do you think "

" As I thought, there's no mistaking the crystal as a crystal from the monster's body. "

" I see, then what about your side? "

" Well, we managed to find several illegal gates and several illegal activities of hunters who were not registered with the guild, but that's all. We may still have to investigate who the perpetrators are. "

" I see, I'll leave it to you, let's arrange a time for us to meet next time. "

" Sure, let's do that "

Izuku then ended his summons with Tsukauchi. He stared in silence for a moment at the starless night sky as he organized his thoughts.

" Looks like I'll be busy for a while "

Several days passed after that day, Izuku and Tsukauchi tried to gather as much information as they could. And when they felt the information collected was sufficient, they decided to hold a meeting. They met at a cafe near the Kiyashi shopping center.

Even though they could have met at the Dawn guild office or the police station, because this collaboration was still confidential they decided to hold an informal meeting to discuss this matter.

When Izuku arrived there was already Tsukauchi waiting for him. Tsukauchi, who saw him, immediately greeted Izuku and invited him to sit down.

" Izuku-kun, how are you? "

"I'm fine, how about you?"

" Me too, "

" Really, but you seem a little tired, is this because of the increase in villain activity lately? "

" Hah... so you know. "

" Enough to see with my eyes "

" I see, as expected of an S-rank Hunter. So is there anything you want to order? "

" Just black coffee please "

" I see, waiter "

The waiter who took their order immediately went to the back to make coffee for the two of them. And when the waiter left, the atmosphere between Izuku and Tsukauchi immediately turned serious.

" Then, can we start the conversation?"

" Of course, I've also installed extra security for that. "

" extra security? "

" let's just say there is an invincible barrier that prevents sound from being heard out"

" I see, it seems really comfortable being a hunter with various abilities "

" I'm just lucky "

" Then shall we start? "

" Right, then... "

Izuku and Tsukauchi spent almost 2 hours discussing while piecing together the information they had gathered so far. Tsukauchi is trying to gather evidence that might lead to the creator of the Nomu while Izuku has got a list of Hunters involved with illegal gate activities. He also received information about where the loot from illegal gates was sold and to whom. It is known that they sold it to a broker named Giran. But their trading places always moved, and they didn't know where the monster corpses and magic stones ended up.

Even though Izuku had tried to send his informants to the trading location, he didn't find anything, even the traces of monster mana that should have remained were also missing as if someone had never come there at all. Izuku who doesn't believe in this also goes to the location only to get similar results.

Listening to Izuku's story, Tsukauchi frowned slightly. He felt he had heard of this broker named Giran somewhere but couldn't remember it.

" What about you Tsukauchi-san? Have you found the whereabouts of the Nomu? "

Tsukauchi who heard Izuku's question immediately sighed. Seeing this without even needing to hear the answer, Izuku already knew that the results weren't good.

" Then what about tracking the League of Villains? "

" Hah... that's also still under search. Since their appearance at UA that day we have continued to track them but there are still no results. "

" I see, do you need help? "

" no need, we'll handle it ourselves for now "

" Okay, if you need help, just say, I will help you as much as I can. "

" Sure, I'll remember that "

There was silence between the two of them as they organized the information they received while drinking their drinks. Amid those thoughts, Izuku then remembers the assumption he made when remembering the UA attack incident that day.

" Oh! That's right, Tsukauchi-san, do you think there is a force or someone behind the League of Villains? "

Hearing Izuku's sudden question, Tsukauchi could only smile weakly.

" As expected of you, you also noticed it "

" so, do you have any guesses as to who might be behind them? "

" roughly "

" Really? Who? "

Tsukauchi seemed silent for a moment thinking about whether Izuku needed to know this. And after a moment of contemplation, Tsukauchi finally decided to tell Izuku.

" Did you remember that Nomu is capable of using several quirks? "

" yes, I remember "

" When another body's DNA meets in a person's body, it is not surprising that rejection occurs and it is not certain that the DNA can be used completely, the same thing also applies to someone's quirk. However, in the case of Nomu, their DNA is perfectly integrated as if it were their own and even being able to use more than one quirk. This seems impossible unless someone intervenes. A person with a quirk can give quirks to other people."

" Does a quirk like that exist? "

" Yes, not only does it give, but this quirk can also seize other people's quirks to become the user's, the name of that quirk is All For One. "

" Then who owns this dangerous quirk? "

" no one knows that man's real name, but he is a human from the early days of quirks. "

" Wait, wasn't that a long time ago? "

" That's right, and I'm sure you've heard of the man who led criminals to control all of Japan and commit crimes as they pleased. He was possibly the mastermind behind the creation of these Nomu. "

"So you're saying we're dealing with the ghosts of the past rising"

" That's how it is. Even though in the past the man should have been defeated by All Might, the man has not been captured and it seems he has started his movement again. "

" Then do you have any other information about that man? "

" Yes, I'm sure you've heard from Grand Torino that All Might received a quirk from his predecessor, right? One For All is the one that comes from that man's quirk which he gave to his younger brother. "

Hearing Tsukauchi's additional explanation, Izuku's thoughts suddenly seemed to stop. Izuku seemed silent for a moment processing what he had just heard but was unable to ask a question as if he didn't understand what they had just talked about.

" What? One For All comes from All For One? Is that true? "

" Unfortunately that's the truth "

Izuku fell silent again, a frown appearing as he tried to understand the absurdity of the story he heard from Tsukauchi. Not only did he reveal the mastermind behind the emergence of Nomu, but Tsukauchi also revealed the origin of his father's powers.

After a few moments of silence, Izuku finally let out a heavy sigh as if he had just added another burden to his shoulders.

" hah... looks like this will be a headache for a while "
