I, with no quirk, become a hero!

"Its name is 'Hyperspace Cube', and it should be considered a mechanical product in essence."

"So it is this that connects my room to yours?"

"Well, this ability is great!"

Seeing that Saitama was very interested in his new creation, Izuku Midoriya patiently explained to him what the "Hyperspace Cube" was.

After finding the black fog's "portal" very useful in his original world, and with Izuku Midoriya having to personally run errands twice recently, Midoriya decided to create a new "portal" first.

It just so happens that Dr. Kusno has this technology. You should know that the reason why Izuku Midoriya was able to come to this world was all because of the cross-world teleportation device that the messenger of hell asked Dr. Kusno to make.

However, Dr. Kusno's technology is still immature. Opening a portal not only requires a huge supply of energy, but it is also prone to overload and breakage after being opened once. Therefore, it is unlikely to open a "portal" to travel on a daily basis.

But after Midoriya achieved a breakthrough in mastering the "monsterization", he asked Dr. Kusno to create a prototype of the "teleportation device", and then he used the "monsterization" technology to activate the core, and thus the "Hyperspace Cube" was born.

Strictly speaking, this is actually an intelligent robot. After Midoriya absorbed the rationality problems of the "Hair Growth Monster" and the "Plague Messenger", this time he only activated the core to enhance his abilities, and did not give him too much rationality.

The intelligence was written by Dr. Kusno. Although it is impossible for it to think like a human, most commands and instructions can be completed perfectly.

In addition, this time, Midoriya only conducted a slight "monsterization" experiment on the Core. Just like Saitama is worried that he will be troubled by monsters, Midoriya is also worried that a rational monster will appear again, and he is afraid that he doesn't know what kind of trouble will happen again.

Therefore, the appearance of the "Hyperspace Cube" remains the same and is not directly transformed into a monster, but the effects of its abilities have been greatly enhanced.

First of all, as Saitama saw, two different space nodes could be connected, so when Saitama opened the door of his room, he came directly to Dr. Kusno's research institute.

I won’t go into detail about other functions and effects for now, but Saitama feels it’s okay this time, because it seems that this "weirdo" created by Izuku Midoriya will not cause trouble to him anymore.

"How could I be defeated in one second?"

The indignant messenger of hell was reborn. He had obviously put on a "hero cloak" and his power had increased greatly, but why did Saitama still kill him with one punch? It's too much!

"Don't worry about this kind of thing for now, just work hard in the future."

Midoriya comforted the messenger of hell appropriately, although he also guessed that it would be this scene, because Saitama is really strong... the kind of strong that can be truly called "invincible".

"I'm so tired. I want to go home too! I lost miserably today."

Saitama was grumbling in annoyance and was about to return to his home, but the messenger of hell blocked Saitama's way in an instant, and asked in fear as if the sky had fallen:

"How is this possible! Saitama, you actually lost. Who on earth can defeat you?!"

Although this fact was a little difficult to say, Saitama still told the messenger of hell while scratching his head embarrassedly.

"The supermarket was having a limited-time sale, and I was left behind by the aunties in City Z. I was lucky enough to get some discounted eggs in the end."

“Hiss! — The fighting power of the aunts and grandmas is so terrifying!”

The messenger of hell gasped and made a decision immediately.

"Saitama! Take me with you to the next supermarket limited-time sale. I will definitely defeat you!!"

"Okay, remember to help me buy more goods when the time comes."

Saitama immediately said that it was very OK, he couldn't grab all the goods by himself, and it was just so good that with one more monster he could buy more discounted goods.

Midoriya on the side rubbed his forehead and said that he didn't want to say anything. If the Hell Messenger wanted to play with Saitama, then let him go. He could just have some peace and quiet.

Time passed quickly, and in the blink of an eye it was the scheduled date for next week. Izuku Midoriya also brought the Hell Messenger to the "Hero Association" headquarters as promised. Even though he was going to let the Hell Messenger help him with heroic activities, he still had to show up and register for the first time.

The headquarters of the "Hero Association" is located in a huge black building in City A. It is said that this building, constructed of special materials, can even withstand a nuclear explosion, but no one has tried to prove it.

When Izuku Midoriya and the Messenger of Hell arrived here, their figures were noticed by enthusiastic people from afar. Citizens enthusiastically took out their mobile phones to take pictures, or said greetings, encouragement and other words.

After struggling to escape from the enthusiastic citizens of City A, Midoriya and the Hell Messenger entered the headquarters of the "Hero Association" and encountered an unexpected blocker.

"Hey! What are you doing in the Hero Association, a dark-skinned egghead like you?!"

A little green-haired girl was floating in the air, her height reaching the same height as the messenger of hell. If not many people knew her identity, they might mistake her for Izuku Midoriya's sister because of her hair color.

28. The Terrifying Tornado

Midoriya actually knew the green-haired little loli standing in front of him... Of course, she couldn't be his sister or something like that, and this person who looked like a little loli was actually much older than him.

She is none other than the second-ranked S-class hero of the "Hero Association", "Tornado of Trembling", and according to reliable sources, she is also the sister of the first-ranked B-class hero, "Hell Blizzard".

After all, they are S-class heroes who are the pillars of this world, so it is not surprising that Izuku Midoriya would collect intelligence on them in advance, or it can be said that collecting gossip about heroes has become Midoriya's instinct.

Izuku Midoriya knew the reason why "Trembling Tornado" was currently standing in front of him and the Hell Messenger. After all, this was also the main reason why "Hell Messenger" was rated as a "Dragon-level" monster by the "Hero Association".

Before he came to this world, he heard the Hell Messenger say that when it was regarded as a threat by the "Hero Association" and heroes were sent to destroy it, all heroes below S-level were knocked unconscious by it, so the "Hero Association" finally sent their strongest combat force, "Trembling Tornado".

Although "Trembling Tornado" successfully defeated and destroyed the Hell Messenger at that time, this guy had an immortal body that could be resurrected no matter how he died. In the end, Tornado did not kill the "Hell Monster" but instead exhausted himself.

Although she was the winner on the surface, it was embarrassing enough to retreat because she couldn't kill the monster. From then on, Tornado completely hated the dark-colored egg-head.

Fast forward to the present, after Tornado made some sarcastic remarks to the Messenger of Hell, she turned her attention to Izuku Midoriya.

"Hey! I heard from the people in the Hero Association that this dark and salted egg head was created by you, right?"

"That's right. Is there anything wrong with it?"

Midoriya responded to Tornado with a gentle smile, which made Tornado, who wanted to find fault with him, at a loss for words.

You can't just say "I couldn't kill that dark, salted egghead you created, so I'm angry and want to cause trouble for you now."

Moreover, the guys in the "Hero Association" had already told her that "Dr. Hell" was going to join the Hero Association and become a new S-class hero. Thinking of this, Tornado snorted, turned around and flew away.

When Tornado himself was far away, Midoriya muttered quietly:

"How do I put it... I can't tell that this "Tornado of Thrill" is older than me?"

Whether in appearance or personality, she is just a little loli. Midoriya feels that Tornado is probably just a little older than Eri, and she is still in elementary school with a schoolbag on her back.

"Of course I can't tell from her appearance. Maybe she's just an old lady pretending to be young."

The hell messenger came over and slandered Tornado, but as soon as he finished speaking, he was thrown out of the headquarters of the "Hero Association" by an invisible force, and no one knew where he flew to.

"I heard it all! You damn black-blooded egghead!!"

The sound of Tornado shouting came through, and Midoriya shut up and went to meet the senior members of the Hero Association. It is better to say less about the matter that trouble can come from the mouth.

The next things were not too troublesome. When Izuku Midoriya arrived at the reception room specially prepared for him at the headquarters, the high-ranking staff warmly welcomed the new S-class hero.

"After discussion, we have decided to rank you as the 15th S-class hero, and your hero name is "Dr. Hell."

"Of course, please don't misunderstand me. The ranking of S-class heroes does not represent your specific strength. We determine the ranking based on your achievements in eliminating monsters and preventing disasters."

"Well, of course I understand that."

Midoriya nodded to show that he understood it very well. The "Hero Association" in this world is similar to the professional hero ranking system in his original world. The ranking of a hero does not represent his actual strength, but is a ranking recognition of the hero's contribution to society.

"It's great that you understand. We, the Hero Association, currently have two trump cards. You just saw the first one, the second-ranked S-class "Tornado of Thrill."

"The other one is 'KING' who is ranked seventh in S-class. It is said that Mr. KING's real strength is even far beyond 'Tornado of Thrill'. This is also a widespread recognition that hero rankings do not represent strength."

"king......"

Midoriya is also very interested in this hero who is known as the "strongest man on earth". It is said that he has solved many "dragon-level" disasters that destroyed cities, and even the "Terrorizing Tornado" was once inferior to him.

"Anyway, the next person who will carry out heroic activities on behalf of you, "Dr. Hell", is the weirdo you created, "Hell Messenger", right?"

"Well, because I am just an ordinary scientist and I don't have any combat abilities."

Izuku Midoriya lied with his eyes open, but the senior members of the Hero Association present all nodded in agreement with him. After all, in their cognition, scientists are equal to ordinary people.

"Then welcome "Dr. Hell" to join the Hero Association."

After everything was discussed, the senior members of the "Hero Association" present stood up and applauded to welcome him. Today, the Hero Association has added another powerful fighter.

After finishing his work at the "Hero Association" headquarters, Izuku Midoriya prepared to return to Dr. Kusino's research institute, and all future heroic activities would be carried out by this messenger of hell.

When Midoriya was about to leave the "Hero Association" headquarters, he saw a ridiculous situation at the gate.

The Hell Messenger was trying furiously to catch the little tornado, but this 2-meter-tall behemoth was being played around by a little loli.

"You damned little dwarf, you actually threw me out of City A. Do you know how tiring it is to run back from such a long distance?!"

"You bastard black-blooded egghead! Who are you calling the dwarf?!"

Using her superpowers, the little tornado can not only fly freely, but every time the messenger of hell rushes to attack her, she will be blocked by an invisible force. She is even now being controlled like a gyroscope and spinning rapidly in place.

"Asshole, make me stop now!!"

"Hahahaha, if you spin 1000 more times I'll make you stop!"

The little tornado was in a playful mood. She controlled the messenger of hell like a gyroscope and made it spin rapidly on the spot. She even created a hurricane that blew away all the documents and papers.

"Cough cough..."

Unable to bear it any longer, Midoriya pretended to cough, and Tornado just glanced at him and continued to play by herself. Her style of doing things never cared about the opinions of outsiders.

But the Hell Messenger couldn't stand it anymore. The Master's cough was a reminder for it to stop playing, so the Hell Messenger took on the "Heroic Stance".

A red cloak appeared directly from behind it, and the Hell Messenger, whose strength was greatly increased, broke the little Tornado's superpower with just a wave of his arm. Suddenly, "Trembling Tornado" looked at this dark egg-head in surprise... How come this guy suddenly became so strong after putting on a cloak.

"Um.....we're sorry but we have to leave first."

After politely saying goodbye to Tornado, Izuku Midoriya and the Messenger of Hell left the headquarters of the "Hero Association". Until now... Tornado is full of interest and curiosity about this "Dr. Hell" who has the same hair color as her.

29. Space Cube

"So...why are you following me?"

Saitama was carrying out his routine patrol, but his calm Buddhist mentality was disrupted again today because a dark-faced guy was following him.

"Because the master wants me to carry out heroic activities on his behalf, but I don't know how to do it specifically, so naturally I just follow you and learn."

The messenger of hell followed Saitama with confidence, and it also put on a "hero cloak" to show that it is now acting as a hero.

"It's annoying. You're interrupting my work."

Saitama was extremely unhappy, mainly because the citizens around him who saw this situation were pointing and talking.

"That's the 'Hell Monster' created by 'Dr. Hell', right?"

"Yes, hasn't it appeared in City Z for a long time? And I heard that it has done a lot of good things."

"Didn't the 'Hero Association' just release news that the 'Hell Messenger', the monster he created, is the one who is carrying out heroic activities on behalf of 'Dr. Hell'?"

"It looks like it's on patrol, but why is it following that bald guy?"

"I don't know, but I remember that 'bald guy' was a C-class hero. He should be teaching me, right?"

................

So Saitama was very unhappy. This guy kept following him and caused him to be pointed at by others. He felt extremely unhappy!

"Would you like to go to Master's place to eat hotpot together tonight?"

"Why!?"

Saitama was stunned by the sudden words from the Messenger of Hell. Was this guy kidding him?

"Because the master said that he had been bothering you for a while, and this time he just happened to become an S-class hero and wanted to celebrate, so he asked me to come and invite you to come along."

"There is such a good thing!"

Saitama agreed immediately. If there is a free delicious meal available, then he would be a fool not to take it.

"Then take me with you to participate in the heroic activities, and let's go to Master's place together in the evening!"

"Easy to say, easy to say!"

Saitama's attitude instantly improved after he had a free meal. Even the black-boiled egg-head that followed him was not so annoying anymore.

City Z is not a peaceful place. On weekdays, there are often monsters that have mutated for various reasons, as well as robbers, bandits and other criminals committing crimes. Generally speaking, it is a division of labor and cooperation with heroes fighting monsters and police catching criminals without interfering with each other, but special circumstances occasionally occur.

"I found you! Saitama!!"

The man who appeared in front of Saitama and the Messenger of Hell had a slightly effeminate face and a slender figure. He was a ninja with his specialty of speed, "Sonic the Speed ​​​​Sonic"!

This ninja originally worked as a killer and bodyguard. After he was defeated by Saitama, he stopped doing his original job and instead made defeating Saitama his primary goal.

"Oh? It's you!"

After seeing him twice in a row, even Saitama remembered Sonic, a guy who was slightly better than the Messenger of Hell, but could also cause trouble for him.

"I have come back from a long and arduous training this time, and I will definitely not lose to you again!"

Sonic's momentum is much sharper than last time. After his last defeat to Saitama, he has been training madly. This time, he is going to use the special moves he has practiced hard to defeat Saitama.

"You are so annoying..."
