I, without any personality, become a hero!

"Uh... what's this?"

Genos was startled by Midoriya's sudden action, but at this moment, the light in Midoriya Izuku's eyes grew brighter and brighter, as if he had seen his favorite thing and was unwilling to let go.

“My master! What’s so interesting about that bald, crappy robot apprentice? Shouldn’t you be focusing on improving my power?”

The "Grim Reaper" expressed his dissatisfaction, and Izuku Midoriya, realizing his actions were somewhat impolite, bowed apologetically to Genos and inquired:

"Um...excuse me, are you an intelligent robot? Or a cyborg?"

"I am a cyborg created by Dr. Kusno, or as you put it, a cyborg."

"Dr. Kusno?"

"This is the one."

Genos was introduced to the kind old man beside him by gesturing with his right hand, and Izuku Midoriya immediately appeared in front of him and bowed.

"Dr. Kussno, my name is Izuku Midoriya! I'm sorry for what happened so suddenly, but could you take me on as your apprentice?!"

"Hey hey!!" X2

Genos and the Grim Reaper stared in astonishment at Midoriya's sudden decision to become his disciple, while Dr. Kuseno, still smiling, inquired:

"If you can create such terrifying beings as 'Hellish Monsters,' why would you want to learn from me?"

"That kind of thing is just a hobby with a little knowledge. My main dream is to strive towards the goal of manufacturing mechanical equipment."

Midoriya, who has been learning manufacturing techniques from Akira Hata since the beginning, no longer strives to become a "hero" after experiencing so much. He simply wants to be a scientist "out of interest".

After witnessing Genos's exquisite skills and the advanced mechanical technology around him that exceeded his imagination, Izuku Midoriya made up his mind to learn from Dr. Kuseno.

Another "Hellbringer" suffered a fatal blow; it was despised by its own master... Was it really inferior to that broken robot?

"Sure, I would love for talented young men to come and learn. After all, knowledge is meant to be passed down to future generations."

The kind-hearted Dr. Kusno nodded in satisfaction and agreed. After all, he was appreciative of Midoriya's talent for creating someone like "Hell Monster".

"My name is Midoriya Izuku. Nice to meet you!"

And so, Izuku Midoriya's plan to learn science and technology from Dr. Kuseno was settled, and then...

--------------

"My master... why are we going to that bald guy's house?"

The "Hell Messenger" following behind Midoriya complained, while Genos kindly led the way. When ordinary citizens in Z City saw the "Hell Monster" appear, they immediately sounded the alarm and then disappeared without a trace.

"Although it's somewhat shameful, you are indeed a 'messenger of hell' that I created, so I must bear the corresponding responsibility."

Midoriya, pointing his index finger, offered insightful comments, his expression like that of a strict father scolding his child.

"I heard from Genos that you've been causing a lot of trouble for that guy named 'Saitama' lately, haven't you?"

"What trouble is there! I've challenged him hundreds of times during this period, and I've been killed and reborn hundreds of times. I should be the one who suffers more losses and injuries."

The indignant "Hell Messenger" had been trying to defeat the "bald guy" for some time, but no matter what it did, it was always killed by a single punch. Finally, when it couldn't think of a way, it asked Dr. Kusno to create a "space portal" and bring its master from the original world. Only by strengthening its own power could it find a way to defeat the "bald guy".

"The teacher has complained more than once that 'Hell's Monster' is impossible to kill; no matter how far you throw it, it always comes right back to you. It's more annoying than a fly."

Genos, who was leading the way, explained, while Midoriya tapped the chest of the "Grim Reaper" on the back with his right hand as a warning. Speaking of which, this guy's height and build are similar to All Might's... Midoriya wondered if the "Grim Reaper" was directly modeled after All Might when it transformed into its monster form.

"In short, we'll go apologize to Mr. Saitama today, at least to prevent others from just punching you to death whenever they see you in the future."

"What does it matter? I can be reborn anyway. The immortal body you created for me, Master, is perfect!"

"Shut up......"

Midoriya was having a bit of a headache. He really needed to apologize to Saitama properly this time. He had always kept in mind what Akira had told him.

Why are they called babies?

"Of course, these adorable babies were made by my own hands, and they are irreplaceable and the best children."

"We, the creators, are like parents to the babies!"

The "Grim Reaper" fell into this world and became a monster. Although he still doesn't understand what happened, Midoriya should at least take responsibility... He should go and apologize to others first.

The abandoned neighborhood in Z City is a place where strange people often appear, so almost all the citizens moved away long ago, but there are still people living there.

"Teacher, I'm back."

In an inconspicuous residential building, Genos was knocking on the door, and soon the door was opened, and a bald head poked out.

"Oh, Genos, you're back."

When he saw that there were other people behind Genos, the bald-headed man flung the door open and angrily pointed at the "Grim Reaper".

"Genos! Why did that bastard come with you?!"

"Hmph! Today I'm here to challenge you again, 'Bald Head'!!"

The inappropriate remarks of the "Grim Reaper," the enraged Saitama... a battle is about to erupt.

Chapter 3 Hot Pot, Here We Go!

Saitama, enraged by the words of the "Grim Reaper," was about to punch the despicable monster in front of him when someone immediately spoke up to dissuade him.

"I'm so sorry, Mr. Saitama! This guy has been causing you a lot of trouble lately."

Midoriya bowed and apologized on behalf of the "Grim Reaper," and Saitama scratched his bald head in confusion... Who is this kid?

"My master, you don't need to do this. This 'bald guy' is an opponent I must defeat!"

"Bald guy..."

Saitama, who was once again enraged, was called the taboo name by this "Hell Monster" whenever he had nothing to do or was bored. No wonder Saitama was completely in a bad mood whenever he saw him.

"I'm so sorry, this is my apology!"

Seeing that things were going badly, Midoriya quickly slammed his right elbow into "Hell Messenger" and then took something out of his left pocket and handed it to Saitama.

"This is?"

"I bought some Kobe beef at the supermarket on my way here; it's just a small gift, nothing more."

"(⊙o⊙)...Please come in, please come in!"

Saitama, whose attitude immediately softened and became cheerful, very kindly invited Izuku Midoriya to his home, which finally gave Midoriya a break. Luckily, he had consulted Genos before coming.

Izuku Midoriya, who was originally going to apologize, should have prepared a gift for his visit. After asking Genos, Midoriya discovered that this "Saitama" was so easy to please, and his recent dream was simply to have a good meal of meat.

To facilitate the flow of funds between different locations, Midoriya, who was originally traveling the world, acquired a "dimensional pocket" Quirk before his trip. This pocket allows him to store items by pinching them together, similar to reaching into a pocket. Currently, it can hold the size of a room, so Midoriya carries a lot of luggage and hard currency like gold with him... all funded by All For One's wealth and friendship.

Having arrived in a strange world he knew nothing about, at least he could still exchange gold for some money. When he visited Saitama again, Midoriya also went to the supermarket to buy a lot of "Kobe beef" as an apology.

Let's have hot pot together!

Saitama was overjoyed. It was rare for a guest to bring such a precious gift, so she decided to cook a delicious hot pot feast to entertain him.

"Teacher, let me do it!"

Genos took the initiative to go into the kitchen to prepare hot pot, and Saitama also unusually offered to make tea and water for Izuku Midoriya.

"Hey, you bastard, do you want to go or not?"

Saitama could only manage a barely polite attitude towards the "Grim Reaper," since its master had brought him a precious gift, and he couldn't afford to be too rude.

"I don't need it. Food and water are meaningless to me. I am perfect as created by my master."

"That's true, you don't even have eyes or a nose on your face, let alone a mouth."

The "Hell Messenger" has a completely ethereal and dark appearance. Apart from its hands and feet, which are not much different from human structures, its entire head is a pitch-black egg that is constantly changing light and shadow, and it does not have the mouth, ears, eyes, nose and other structures that humans must have.

However, none of this bothered Saitama. He had seen and fought countless monsters, and he was used to all sorts of monsters. At most, this seemingly indestructible creature in front of him annoyed Saitama a little, but to him, it was essentially the same thing.

Saitama's thought at that moment was that when they ate beef hot pot later, there would be one less mouth to feed, and he could eat more slices of meat.

"By the way, Mr. Saitama... I'd like to ask you something."

"Oh, what is it?"

Saitama himself is very good-natured when it comes to guests who bring him precious "Kobe beef".

"Do you know how monsters come about in this world? I heard from Genos that you, Saitama, are very strong... and have defeated quite a few monsters, so you should be quite familiar with this, right?"

"I'm very interested in the fact that the 'Grim Reaper' transforms into a monster and gains life."

After hearing Midoriya's question, Saitama waved his hand dismissively, looking rather bored.

"Who knows... I once met a guy who turned into a weirdo after eating too many crabs. Who knows how these weirdos are created?"

"Um...can eating too many crabs turn you into a weirdo? This is a very valuable piece of information."

Midoriya suddenly became more and more curious about this world. The "Hell Messenger" gained life and became a monster, and eating too many crabs can also turn you into a monster... There is great research value in this.

"Anyway, thank you very much, Mr. Saitama."

"No need to thank me. If you really want to thank me, then tell that guy next to you to stop bothering me."

Before Midoriya could even say anything, the "Grim Reaper," specifically named by Saitama, suddenly stood up and declared:

"That's impossible. The reason I became what I am now is to defeat you, Saitama!"

"!!" x2

Both Izuku Midoriya and Saitama were astonished, stunned by the words of the "Grim Reaper".

Midoriya was surprised by the meaning behind the "Hell Messenger's" words. Judging from its current monster form... it seemed that it had transformed into a monster in order to defeat Saitama because Saitama was unharmed within the explosion's range?!

Saitama was even more astonished. After calling him "bald" for three months, this bastard monster actually called him by his real name for the first time ever. You see, Saitama tried every time to correct the "Hell Messenger" and make it change its way of speaking, but this guy was killed and resurrected countless times and still wouldn't stop calling Saitama "bald".

"My master said that if I address you by your full name, 'Saitama,' you'll accept my challenge, right?"

Saitama immediately turned his gaze to Izuku Midoriya, who was sitting down. Midoriya picked up his tea and drank it all in one gulp, as if it were none of his business. He didn't intend to stop the "Grim Reaper" from challenging Saitama. Anyway, this guy could be killed hundreds of times and still be resurrected unharmed. It just so happened that he also needed to collect enough experimental information.

"Fine... as long as you honestly call me by my name, you can challenge me however you want."

Saitama simply picked up his teacup and drank it all in one gulp. Anyway, he had gotten used to this thing harassing him for the past three months. As long as it didn't keep doing something stupid like calling him "bald head," Saitama could barely accept it.

"The beef hot pot is ready, let's all eat together."

Genos brought out the beef hot pot from the kitchen, and it was time for a joyful battle.

"Genos-kun... you can actually eat!?"

"Well, strictly speaking, I am a cyborg, and I can eat."

"Wait! You can't eat, right? And where the hell did you eat from?!"

"Haha, you didn't expect that, did you, Saitama! I can eat directly by breaking things down."

"Stop it! You're just wasting delicious food!"

"Wait, this piece of meat is mine!!"

Chapter 4 House of Evolution

The following day, Izuku Midoriya devoted himself to learning new mechanical knowledge from Dr. Kusno. He has now officially settled in Dr. Kusno's laboratory, where he learns the knowledge and skills he needs as a new trainee scientist.

Wearing a white lab coat and sporting a striking green head of hair, Midoriya was busily adjusting the machinery in his hands. Practice combined with theory is the best way to grow and improve. Immersed in his work, Midoriya had no time to notice his surroundings.

Finally, the person standing to the side... no, the strange creature finally couldn't hold back any longer and began to complain:

"My master, shouldn't you be trying to increase my combat power first so I can defeat that 'bald guy'? That's how it should be!"

The "Grim Reaper's" complaints had an effect; Midoriya put down his work to rest for a moment, then turned to his creation and said:

"This matter can't be rushed. First of all, I've just arrived in this world and haven't made any progress in the research on so-called 'monsterization,' nor do I have enough data to refer to yet, so..."

"So?"

"Now let me get down to business. Once I've thoroughly studied Dr. Kusno's knowledge, I'll build you a set of mechanical armor just like Genos's, okay?"

"........."

Startled by Midoriya's words, the "Grim Reaper" quickly left the research room to calm down. If its perfect body were covered in the same scrap metal as its "bald" apprentice, it would probably be a psychological trauma it would remember for a lifetime.

"This absolutely cannot be allowed to happen!"

Clearly sensing that Izuku Midoriya was about to get himself into trouble with the "Hell Messenger," it immediately started racking its brains for ideas... On one hand, it wanted to strengthen its own combat power, and on the other hand, it wanted to provide its master with enough useful information.

In order to avoid being encased in armor of scrap metal, the "Hell Messenger," having mustered all its strength to think of a solution, suddenly came up with a brilliant idea.

Without hesitation, the "Grim Reaper" immediately took action. Based on its understanding of Midoriya's personality, this method was sure to be very effective.
