Hello, everyone. Back to update this chapter for you all. Thank you all so much for the love and support for this story. And so sorry for the late update.

To say that Izuku was nervous was an understatement. Just a few minutes ago, he heard knocking on his door and answered it. He thought that must have been Tomura or Kurogiri checking in on him. But he was shocked to see someone else on the other side of the door. The man before him was tall and had an intimating aura around him. He also wears a business suit and a black mask that was covering his face so it was hard to tell what he looks like.

One could argue that the man looked like a villain. But Izuku wasn't going to do that to this man. Especially when the man is revealed to be the landlord of the apartment. So when the landlord politely asked to come in, Izuku did that without any hesitation. Was the man here to collect the rent money already? The rent wasn't due for another week. So why was he here?

"Tomura seems to have taken a fondness for you, Midoriya-san," The landlord said.

Izuku blush when the man mentions Tomura. Ever since moving here, Tomura and him have been coming closer each time they spend together. The older boy was becoming more and more like an older brother to the younger boy.

"Oh? Yes, Tomura-kun is very kind to me, sir. Both him and Kurogiri," Izuku said with the blush still on his face. It made him look like a strawberry. Which was adorable to look at.

Even All For One found the young boy to be too adorable. Both Tomura and Kurogiri had often said that Izuku was extremely cute. According to both of them, the boy's smile was very bright. Brighter than the sun itself. All For One had originally that was the buy's Quirk. Matter of fact, he was originally just going to meet him just to see his Quirk himself. However, when Tomura had revealed that the younger was born Quirkless, the ancient villain was actually surprised.

"I've wanted to thank you so much for letting someone like me live here. I just hope that I didn't do anything that you might dislike, sir," Izuku said, bowing a few times to show his gratitude towards the man.

The green-haired boy went over to his kitchen and grabbed something from his small refrigerator. It was a gift basket with fruit in it.

"I bought this for you just today. I was going to ask Tomura-kun if I could meet you tomorrow, sir," Izuku as he handed the gift basket to his landlord.

All For One was now quite stunned to see that boy had brought something for him just to thank him for living here. It has been a while for someone to actually giving him something. The man wonder if Izuku was planning something on the League of Villains.

So, he uses one of his Quirk to see what he was planning. Going through the boy's mind, All For One founded nothing. Izuku just wanted to be nice. The man even smiles when the boy had wished for the former to get better.

However, All For One had seen the memory of Izuku meeting All Might. Tomura Shigaraki did say that his young friend had met All Might and the latter had told the boy that he couldn't be a hero without the help of a Quirk. But the man had never imagined that Izuku had actually seen All Might in his true form. It was quite funny to All For One. All Might had crushed the hopes and dreams of his biggest fan, and now the boy was living under the same roof with two dangerous villains. It's irony. Perhaps this could work out in his favor. After all, Tomura did also say that Izuku had a notebook on the Pros and their Quirks.

"Thank you for the gift, young man. It's such a nice thought to think of," All For One said as he took the gift basket from the boy.

"Oh, no. It was nothing special. I just wanted to thank you, sir. That's all," Izuku said blushing.

This man before him was such a kind and caring soul. The poor man was suffering from something that made his health fragile. Izuku had never imagined that his landlord's health was that bad. Perhaps he should make have tea for him the next time he visits.

"If you excuse me, I have to leave for now. It was wonderful to meet, Midoriya-san," All For One said, taking his leave.

"You can just call me Izuku, sir," The green-haired boy said.

All For One smile at the young boy. He was so trusting and innocent. It was hard to find someone like that today. Frankly, the kid was too cute for his own good. The man had wondered if the young boy had lied about being Quirkless and his actual Quirk could charm anyone he meets.

"And you can just call me Sensei. Tomura calls me that as well," All For One said.

Izuku nodded. His landlord was a nice man, "Of course, Sensei," The green-haired boy said happily.

"Tomura Shigaraki is also my adoptive son. So thank you for being his friend, Izuku-san," All For One said, riffing the boy's hair like a father would do with his son.

At night

Later that night, Izuku was watching TV in his room. It was just him since Tomura and Kurogiri had something to do with something. Not that Izuku shouldn't complain. His kind neighbors can't always spend all the time with him. Although, Izuku did wonder what they were doing.

The green-haired boy was watching a history show that was about an American scientist telling his theory of how Quirks were much older than the public thought.

"In my research, I've had discovered some stories of rulers or healers of powers that are similar to that of Quirks. I believe that Quirks have been around since mankind had existed," The scientist said.

Izuku was very amazed. He began to write down everything he could on what the scientist said on how Quirks had already existed before the first report in China happened.

"The Quirks users in those times were either worshipped as gods or feared as devils for their powers. During my search for answers, I've had found ancient temples around the world of images on the walls of people using their powers for either good and bad. Quirks in those times were much rarer then."

Izuku had written almost everything down. This was amazing. He began to mutter as usual. The green-haired boy wonders what was it like to have a Quirk back then. The scientist had even said that Quirks had always been part of humanity.

"If this true, then everything we thought knew about Quirks is wrong. This also means that Quirks have helped build many civilizations like how they build a hero society. This also means that Quirks have been growing more since the last centuries. If so, we're they hiding their powers from everyone?" Izuku mutter to himself since no one was with him.

"I've got to tell Tomura-kun about this when he gets back. I just help he'll like hearing this," Izuku said.

Since it was discovered that he was Quirkless, Izuku had developed a liking to study Quirks. He watches the Pros using their Quirks to stopped villains from attacking people. He also carefully watch villains and criminals using their Quirks of breaking the law. The young boy had always felt those Quirks could be good at heroism no matter how dangerous they were. After all, there are no such things as bad Quirks but bad users.

Okay, everyone, that's it for this chapter. I hope you guys like it. I also hope that you all like the meeting between Izuku and All For One and the little quirk theory that I've made.
