I, without any personality, become a hero!

Of course, you could tell from Saitama's expression that this bald hero didn't want to join the "Fubuki Group," but he had been suffering from various harassments from Hellish Blizzard recently.

"It's so annoying! That woman comes to my house every other day. Can't you tell her to stop coming if she's your sister?!"

"Correction! I don't have any extra brothers or sisters, and besides, what business is it of mine if 'Hellish Blizzard' is looking for Saitama?!"

Midoriya was furiously making sarcastic remarks when a seductive female voice drifted over, accompanied by the sound of a door opening.

"I think I heard you talking about me?"

Immediately, everyone turned their attention to the entrance, where a stunningly beautiful woman with an alluring figure and appearance, dressed in a dark blue robe, appeared before them. Saitama jumped up in astonishment, exclaiming:

"Why are you here again, woman! Wait, how come you have a key to my house!?"

"Of course, I burned a copy when I came last time so I could have it copied later, which would make it easier to wait for you to come back from your house."

"This is trespassing, which is a crime!!"

Seeing Saitama and Fubuki arguing loudly, Midoriya immediately turned his head aside and asked Genos.

"Could this person be interested in Mr. Saitama?"

"I don't know... but teachers always attract all sorts of people, and aren't you and Midoriya the same?"

"No... I mean that kind of interest... never mind."

Seeing that Genos remained silent, Midoriya decided not to ask any further questions, regardless of his relationship with him.

"So, what were you talking about me about just now?"

Hellish Blizzard naturally sat down at the corner of the square table, and if someone didn't know better, they would really think she was the lady of the house.

"We were just talking about your sister."

"My sister..."

Saitama's words directly touched on Fubuki's sore spot, and the beautiful woman immediately lowered her head and fell silent. Fortunately, Genos sensed the situation was getting out of hand and added:

"We're talking about 'Tornado of Terror' and how she treated 'Dr. Hell' like her younger brother."

"Dr. Hell?"

"Hi...it's me..."

With a miserable expression, he pointed to his own Izuku Midoriya. If it weren't for Tatsumaki's stubbornness and persistence, he wouldn't have come to Saitama's house for refuge.

"I see... No wonder she's been acting all mysterious lately, saying she wanted to take me to meet someone!"

After carefully observing Izuku Midoriya's Hellish Blizzard, the mystery of why his older sister "Tornado of Terror" had recently changed her attitude has been solved.

Chapter 53 You're just a little brother!

After recounting the recent visit from Little Tornado, Izuku Midoriya said to Fubuki in a helpless and embarrassed tone:

"I've clarified this many times, but she still stubbornly believes I'm her brother. So could you please explain this to your sister?"

"I'm sorry, I can't help you either..."

"Hey! Why?"

Seeing Midoriya's exhausted and troubled expression, Fubuki felt rather embarrassed and turned her head to the side, muttering softly:

"Actually... my relationship with my sister isn't very good. We live separately now and it's rare for us to run into each other."

"I see... It seems I'll have to figure it out myself."

Midoriya, tapping his fingers on the square table, was trying to shake off Tatsumaki's entanglement when Hellfire spoke up again:

"However, I roughly understand my sister's stubbornness. 'Doctor Hell,' your hair color is the same as hers, and you also possess 'superpowers'... Who knows, you might really be our little brother?"

"I already told you! Don't add these baseless relationship settings to my story! I won't accept anything that has no basis whatsoever!!"

"But you don't have any evidence to refute your sister's claims, do you?"

"I......."

Despite feeling a deep stomach ache, Midoriya, with his extensive scientific knowledge, could easily produce more than ten different bloodline identification procedures in a matter of minutes. However, his little tornado only trusted her intuition as a woman and even stubbornly believed that Midoriya would use his advanced scientific skills to forge documents to deceive her, making it impossible for her to explain herself.

"What does it matter? Anyway, that little brat treats you like a younger brother, so just accept that relationship and be her younger brother! It's not like you'll lose anything."

Saitama, who was reclining on the tatami mat drinking tea, interjected with the observation that an outsider's perspective is often clearer, and Genos nodded vigorously in agreement with his teacher's words.

"I refuse! How can you decide blood relations so casually?"

Izuku Midoriya, who was making a last stand to preserve his male dignity, was called "little brother" by Tatsumaki, who looked exactly like a little girl. It was simply impossible for him to accept this situation... Besides, he wasn't even from this world.

Midoriya is determined to correct the stubborn Tatsumaki, and for the next few days he plans to stay at Saitama's house to avoid trouble, as being constantly bothered by Tatsumaki is very painful.

Just as Midoriya was about to ask to stay at Saitama's house for a few days, the door was suddenly opened with a "bang," though it was as if it had been pushed off the door frame.

"Found you, little brother!"

It was a small tornado that came from Saitama's house. Unfortunately, the front door of Saitama's house was torn down by "superpowers," and everyone in the house was stunned.

"Aaaaah! My front door! What are you doing, you little brat?!"

Saitama immediately jumped up in anger, while Tatsumaki pouted disdainfully. However, she still used her "superpowers" to put the door back on, since she might get beaten up if she really angered Saitama... although the door fell down again as soon as it was put on.

"Sister...Sister!?"

"Oh? Fubuki, you're here too! That's perfect!"

The stunned younger sister, Hellish Blizzard, was met with a sudden, dramatic response from her older, more mature sister, Little Tornado, who floated down in front of Midoriya and pointed directly at him, saying:

"This is 'Doctor Hell,' our younger brother whom we've never met."

"Don't try to set me up like that! I've said it so many times, I'm not like that!!"

Midoriya was about to explode from being pestered so much. He had explained countless times but couldn't change the little tornado's stubborn mind. This was driving him crazy!

"By the way... how did you know I was at Saitama's house?"

"Oh? Of course, I got it from that guy with the jet-black bald head in your house. I went to the research institute to look for you but you weren't there. I just happened to run into that guy in Z City, and it was easy to find out your location from him."

"........"

Unable to utter a word, Midoriya decided to kill the Grim Reaper later; for now, he needed to deal with the older little girl clinging to him first.

"Anyway... I'm not your brother, I've said that many times!"

"I understand! It's because having two older sisters all at once puts a lot of pressure on you, but I'll help you get used to it gradually."

"No...you're fundamentally mistaken."

Midoriya was speechless, but with so many people around, including Saitama and Fubuki, he decided to explain the situation to Tatsumaki.

"Let's get this straight! I'm not your brother, Saitama and Genos can testify to that!!"

"Oh, really?"

Turning their attention to the small tornadoes on the two onlookers, Saitama took the lead and raised his right hand to speak:

"I can testify! Aside from hair color, superpowers, and always causing me trouble... you and that little brat seem to have quite a lot in common. Midoriya, are you really not her brother?"

"........"

Midoriya, his finger trembling as he pointed at Saitama, remained silent. Was this bald-headed guy deliberately trying to screw him over?

After listening to Saitama's words, Tornado nodded in satisfaction. Although this bald-headed bastard called her "little brat" again, she would let it go this time since he had said something in support of her.

"Genos, you're the only one who can say something fair!"

Turning his gaze to the wise and reasonable "Cyborg," Midoriya believed that Genos wouldn't speak carelessly; this was his trust in him as a friend.

Upon seeing Izuku Midoriya's gaze, Genos nodded, the cyborg understanding what he should say.

"Midori-kun is actually very mysterious. Neither my teacher nor I know his past or origins, but his ability to create a monster like 'Hell Messenger' is quite remarkable. He does indeed share some similarities with 'Tornado of Terror,' the second-ranked S-class monster."

"Genos—you!"

Seeing the eerie smile on the "cyborg's" face, Midoriya knew that this guy was taking the opportunity to get revenge on him. Because he had modified and upgraded the guy without permission, adding a lot of drills to his body, Genos was taking the opportunity to finish him off.

"So that's how it is... I didn't know any of this."

With a look of pity on her face, Tornado looked at Izuku Midoriya with compassionate eyes and said in a heavy and sorrowful voice:

"Because your 'superpowers' were discovered when you were young, you were captured and imprisoned in a research institute of an evil organization for experiments. As a result, you have lived a miserable life without seeing the light of day for many years. That's why I haven't been able to find any information or intelligence about your past. And you must have learned that forbidden scientific knowledge in the research institute, right?"

"Hey! Don't just jump to conclusions and fill in the blanks in my head! It's not like that at all!!"

No matter how hard Midoriya tried to refute, after Tatsumaki made those remarks, everyone present looked at him with pity, as if Midoriya had really been subjected to inhumane research experiments in the past.

Chapter 54 You wait, I'm going to cause trouble right now!

In the end, Izuku Midoriya still managed to slip away... Under the pitying gazes of Saitama, Tatsumaki, and the others, he couldn't bear it any longer and let the "Hyperspace Cube" open a door before running off. In this situation, he was utterly frustrated and speechless.

Instead of returning to Dr. Genos's research institute, Midoriya was afraid that Tatsumaki would run there to look for him again, so he went to Dr. Genos's underground research institute instead.

Dr. Genus, who switched careers to sell takoyaki, originally had his cyborgs dig an underground warehouse to store things because of land use issues. However, they accidentally dug it into the size of an underground research institute.

Recently, Midoriya borrowed equipment from Dr. Genus's research institute. After all, Dr. Genus's institute is full of mechanical equipment, while Dr. Genus is an expert in biological science equipment.

In short, in this world, besides Saitama and Dr. Genos, Midoriya can also be considered a friend of Dr. Genos, after all, he has benefited a lot from Dr. Genos's knowledge.

Boros, the cosmic overlord who was recently rescued by the messengers of hell, has been recuperating in Dr. Genus’s underground research facility. With this period of rest, Boros’s injuries have been largely healed, but he is still undergoing rehabilitation work... such as using a certain messenger of hell as a punching bag.

Having fled from Saitama's house, Midoriya, having nowhere else to go, ended up at Dr. Genus's place. Coincidentally, Midoriya was also planning to visit Boros to see how he was recovering.

The "Hyperspace Cube" opened a portal directly in the takoyaki shop in Z-City. After Midoriya walked out of it, he saw the armored gorilla in charge of grilling takoyaki.

"Oh, it's Dr. Midoriya! Dr. Genus is in the underground laboratory, so I don't need to show you the way, right?"

"No need, by the way, how's business lately?"

"It's alright, since we don't need to factor in the cost of the octopus, so overall we're still in a profitable position."

"This is definitely a very profitable business... Oh, and get me a serving of takoyaki too."

Midoriya took the takoyaki from the armored gorilla and casually stuffed a takoyaki into his mouth. It's definitely worth it to mooch some food and drinks when visiting a friend's house.

Of course, Midoriya was originally planning to stay at Saitama's house to avoid trouble and also get a free lunch, but after Tatsumaki came, he had to move again and ended up getting a free lunch at Dr. Genus's house.

Having been here several times before, Midoriya knew the route well. After taking the elevator from the warehouse to the underground research facility, he headed towards the room where Boros was. This cosmic overlord had now stepped out of the glass tank, but his combat power had not yet fully recovered.

Upon arriving at the destination room, Midoriya saw the cosmic overlord Boros assisting Dr. Genus in collecting data. Midoriya, still eating takoyaki, greeted him directly:

"Boros, it seems you're recovering quite well lately?"

"Is this Dr. Midoriya? Thank you for sending the Grim Reaper to accompany me during my rehabilitation training."

Boros rarely expresses gratitude to others, but not only was his life saved by Dr. Midoriya, who also specially sent the Grim Reaper to fight and recover with him, because Boros yearns to fight against the strong... Although the Grim Reaper isn't very strong at the moment, its immortal body makes it the most enjoyable punching bag.

Under the weight of all these favors, Boros also developed a good impression of Midoriya, after all, he had helped him contact Saitama, giving him another chance to challenge that invincible man in the future.

"It's okay, just beat that Hellbringer as hard as you want, you can beat him to death a thousand times over!"

After settling his personal score by drawing a mark on the messenger of hell, Midoriya turned to ask Dr. Genus a question.

"So, any breakthroughs in your research?"

"No, the cellular structure of aliens is completely different from that of Earth... or rather, only Boros's cells are this outrageous."

Dr. Genus, who is currently conducting research on Boros, has of course obtained permission from this cosmic overlord; otherwise, angering him might mean destroying the entire Z City.

"I don't have any good solutions on my end, so you should take over this... You know Saitama better than I do."

Dr. Genus, who was communicating with Midoriya, returned to his old ways because Boros, the cosmic overlord, had asked him for a favor.

Boros needs to become stronger—he must become stronger than he is now—to defeat Saitama, he must be much stronger than his former self.

Previously, Boros was so powerful that all he thought about was sealing his own power. But now he knows that there is a man even stronger than himself. He needs to do something he never thought of before: he must strive to become stronger to defeat that man, the hero named Saitama!

Boros, as the ruler of the universe, also had a very high vision. After learning about the amazing scientific technology of Dr. Genus and Dr. Midoriya who saved him, he personally asked the two to conduct research on him, hoping to become stronger than he was now as quickly as possible.

Boros wanted to challenge Saitama, but he was a defeated opponent who had just been defeated, and he had not even recovered his original power. Therefore, Boros's primary goal now was to become stronger.

During this time, in addition to recovering his body, Boros has been cooperating with Dr. Genus in research experiments, although it seems that the genius scientist cannot come up with any better solutions at present.

"I understand. Leave the Boros matter to me."

Originally somewhat resistant, Midoriya immediately agreed. After all, Saitama, with his bald head, had just conspired with Tornado to trick him, so it would be strange if Midoriya didn't take the opportunity to cause him some trouble.

"Dr. Midoriya, do you have any good ideas?"

"It's not great, but it depends on whether you're willing to give it a try."
