I, without any personality, become a hero!

"You want to know? Then I'll tell you!"

"What?!" x2

Meanwhile, the Grim Reaper and Genos were extremely surprised. Genos had a listening device on the salted fish doll that allowed him to know what was happening, but Saitama was about to reveal his powerful secret without holding anything back, which was simply astonishing!

"This is a rigorous training that is comparable to hell, which is why I was able to become so strong in three years!"

"Three years of arduous training..."

Looking at Saitama's serious expression, the Hell Monster couldn't help but feel a chill... He couldn't even imagine what kind of terrifying training it would take to become so powerful.

"100 push-ups! 100 sit-ups! 100 squats! Plus, run 10 kilometers! Do all of these every day!!"

"What......."

At this moment, even the dead fish costume stared wide-eyed at Saitama's answer, which was too shocking.

"In short, you must stick to these exercises every day, and of course, you must eat three meals a day properly. You can eat a banana for breakfast..."

Saitama was adding notes to the precautions when, at that moment, the salted fish mascot costume finally collapsed and exploded, unable to withstand the damage from the battle.

"Wait! It's you?!"

The disguise burst open, revealing his true form. Saitama discovered that the guy called "Salted Fish Man" was actually "Hell Monster," and he was immediately confused about what tricks this guy was up to now.

"So it's been exposed? Well, there's nothing we can do about it!"

It suddenly leaped up and attacked Saitama's messenger from hell, taunting him as it did so:

"Didn't expect it to be me, did you! Once I know the secret to your strength, Saitama, I can completely defeat you!"

"Take this! This is the third move: 'Salted Fish Smash'!!"

However, it was met with a fist wearing a red glove, and the scene of instant death was repeated without any surprise. The figure of the messenger of hell turned into ashes and disappeared.

"If you want to know this kind of thing, just ask me directly. Why bother with these weird tricks!"

Saitama flicked the non-existent cigarette ash off his hand. With the annoying culprit gone, he could finally go home and watch TV.

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

"That's the secret to Saitama's strength!"

Inside Dr. Kusno's research institute, the Grim Reaper honestly told Izuku Midoriya everything it had discovered, but Midoriya just looked at it with a "you're kidding me" expression.

"I said... even if you're going to fool me... at least make up a plausible lie."

"It's true, Saitama said it himself, and I even confronted him about it later!"

"Alright...alright, let's not dwell on this."

Izuku Midoriya decisively changed the subject. The possibility that the Grim Reaper was lying to him was out of the question, so it meant that Saitama was lying to him? But that was unlikely too... So the problem lay in this world.

Even if the "Hell Messenger" can become a monster with life, Midoriya can still accept it.

Chapter 10 "Hair Growth Tonic" (Part 1)

"Alright, take this to Mr. Saitama."

"Master, what is this?"

The messenger of hell pointed to the item Midoriya had given him. The outer casing was a shampoo bottle, but there was no label on it, just like any other counterfeit product on the black market.

"Have you forgotten the time we visited Saitama's house?"

Last time, when Izuku Midoriya brought "Kobe beef" to visit Saitama's house, everyone gathered around to eat hot pot and chatted about things they were interested in. Saitama complained about the "Hell Monster's" BUG-like constitution, which is that he can't be killed and can immediately revive.

Midoriya awkwardly explained the principle of the "Hell Messenger," and he hadn't expected that he would become an indestructible being after turning into a monster.

Genos then praised Izuku Midoriya, saying that a 16-year-old boy who could create a "Grim Reaper" was a very talented and brilliant scientist.

At that moment, Saitama suddenly joked and said this:

"Can you invent something that makes hair grow on a 'bald' head? ...Ah, no...that was just a joke."

Although Saitama immediately brushed it off, Midoriya still kept it in mind.

"I've been analyzing Dr. Genus's research data recently, and this is a product I developed incidentally. I'll give it to Mr. Saitama to try."

"Huh? We're going to give this to that 'bald guy'?"

Hearing the slightly disdainful tone of the Grim Reaper, Midoriya offered a serious critique:

"You're always causing trouble for people. Remember to bring a gift when you visit so you won't be turned away."

"All right......"

Following his master's instructions, the Grim Reaper decided to bring the invention that Midoriya had researched to Saitama, so that he could at least justify causing trouble for him in the future.

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

The Grim Reaper quickly arrived at the abandoned area of ​​Z City. It skillfully knocked on the door of Saitama's residence. Saitama happened to be at home with nothing to do that day. When he opened the door and saw the "Grim Reaper" with its jet-black bald head, his expression turned somewhat disgusted.

"What are you doing here at my house again?!"

"This is something Master asked me to bring to Saitama. Make good use of it!"

"Um... what is this?"

When the Grim Reaper handed him a bottle of unbranded shampoo, Saitama's expression twisted slightly... because he's bald... a bald man using shampoo, what a funny joke~~.

"This new product that Master researched and invented was created especially for you, so cherish it!"

"Oh, thank you so much!"

Saitama's expression immediately turned to joy. He never expected that the boy named Midoriya Izuku was such a kind person. Not only did he bring him "Kobe beef" last time, but this time he even specially researched "hair growth serum" for him. He was simply an angel!

Saitama immediately took the "hair growth serum" from the messenger of hell and welcomed the "hell monster" who usually annoyed him into the house. Then he happily ran to the bathroom to try using the "hair growth serum".

"What's wrong with the teacher?"

Genos, carrying a quilt that needed washing and drying, came out of the house. He looked at Saitama, whose behavior was very strange, and the "Hell Monster" who had come to visit. He was a little confused about the situation.

"That's how it is..."

The Grim Reaper explained the situation clearly, and Genos suddenly realized... So that's what it was about. Saitama has always been very concerned about being "bald".

"Yesterday they somehow got hold of a huge pile of 'seaweed,' but there's no medical evidence to suggest that 'seaweed' has any beneficial effect on promoting hair growth."

Genos commented on what happened last night, and the Grim Reaper nodded in agreement with his jet-black bald head.

"What's wrong with being bald? You don't have to worry about the hassle of going to the barbershop, and it's not like you're ashamed to go out in public."

"Shut up, you heretic! I heard you!"

Saitama emerged from the bathroom, his head still covered in "hair growth serum" foam, but he didn't seem to care and pointed angrily at the Grim Reaper, saying:

"I used to have thick, black hair too. You 'bald weirdo' would never understand how I feel!"

"Compared to me...you're more like a 'bald weirdo'..."

The Grim Reaper was speechless, while Saitama himself clenched his right fist and placed it against his chest, saying confidently:

"Soon I won't be called 'bald' anymore, I can feel it!"

"Life! Life is growing above my head!!"

Seeing Saitama's confident demeanor, both the Grim Reaper and Genos were astonished. Could it be that Saitama's hair was really going to grow back? ...This "hair growth serum" is just too amazing!

"Soon, a completely new me will appear before you!"

Saitama turned around and ran back to the bathroom to wash the foam off his head. He could feel life blooming on his head, a sign that his thick, black hair was returning.

Saitama has returned to the presence of Hellbringer and Genos, but the two witnessing this scene are speechless, which might... undermine Saitama's confidence.

At this moment, after rinsing off the "hair growth serum" foam, Saitama's head not only showed no signs of hair growth, but instead became even shinier and rounder. To give a rough example... if a werewolf saw Saitama's head, it might be like witnessing the moon and instantly transforming.

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

Brighter and rounder, you'll never have to worry about dim lighting again. This bald head is enough to reflect light and illuminate all darkness.

Saitama lay on the floor as if he had lost his soul, not wanting to say anything or do anything... He was just a salted fish without dreams or a future.

"Could it be that Midoriya made a mistake?"

Genos picked up the "hair growth tonic" and examined it closely. The packaging looked exactly like a black market product. Could it really be something that could help with hair growth?

"Impossible! My master doesn't make mistakes!"

After snatching the "hair growth serum" from Genos, the Grim Reaper arrived at the potted plant by Saitama's window. It opened the bottle and poured out a little of the "hair growth serum."

Suddenly, some of the withered flowers in the potted plant burst into life, as if spring had arrived, and began to grow rapidly. In an instant, the potted plant was filled with delicate flowers that could only be seen in spring.

"look!"

Pointing to the pot full of blooming flowers, this was the best proof of the remarkable effect of the "hair growth agent," and the Grim Reaper would not allow his master's greatness to be questioned.

"It seems... this can only be Saitama's own problem."

Genos nodded, seemingly indicating that Saitama's immense power came along with his bald head, and that no method of "hair growth" would work on him.

"This is outrageous! I refuse to accept this reality!"

Saitama, who had been lying on the ground like a salted fish, got up and started shouting angrily. Just as Genos was about to comfort him and tell him to accept the situation, an unexpected event occurred!

The "hair growth serum" in the hands of the Hell Messenger began to pulsate with life. Sensing something was wrong, it immediately dropped the serum on the ground, and the serum burst into white foam, undergoing a violent change.

In Saitama and the others' eyes, white bubbles formed to the height of a person before bursting apart, revealing a strange person covered in long black hair.

"I am the 'Hair Growth Potion Freak,' born from my resentment at being unable to make a 'bald' person grow hair!"

"You bastard, who are you calling 'bald'?!"

Hitting a nerve, Saitama's eyes turned bloodshot as he roared and screamed.

Chapter 11 "Hair Growth Agent" (Part 2)

Saitama was almost choked to death by a single sentence, but then something unexpected happened.

“That bald guy! That despicable bald guy!!”

Suddenly enraged and howling, the "Hair Growth Potion Monster" launched a direct attack on Saitama and the Grim Reaper, its black fur extending out to entangle and attack them.

"Brother, what are you doing?!"

Because it was also a creation of Izuku Midoriya, the "Hair Growth Potion Monster" was treated as its own brother by the Grim Reaper. However, for some unknown reason, this guy suddenly attacked it as well.

"You bastard, die!"

Saitama, already in a panic after being repeatedly mocked, spread his arms to free the hair wrapped around his body, and then unleashed a punch powerful enough to instantly kill anything.

Seemingly sensing imminent danger, the "Hair Growth Potion Monster" immediately used its life-saving technique. Saitama's punch pierced through a large pile of white foam, and the "Hair Growth Potion Monster" had already vanished without a trace.

"Baldy! All bald men deserve to die!!"

Having somehow reached the rooftop of an abandoned building outside Saitama's house, the "Hair Growth Potion Monster" was roaring loudly before running directly towards the center of Z City.

"You bastard, stop right there!!"

Saitama, who hadn't even changed into his hero costume, jumped out of the window in his pajamas and went straight after the "hair growth serum monster."

"What's going on?"

Before Genos could react to what had just happened, and after the Grim Reaper had loosened the black fur binding it, it hurriedly said to Genos beside it:

"Jenos, you have Dr. Kusno's communication device on you, don't you!?"

"Yes, I do. What do you want to do with it?"

As a cyborg, Genos is equipped with many combat-functional parts and devices, as well as communication equipment from Dr. Kusno, so that he can easily return for repairs in case of any damage or malfunction.

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

Izuku Midoriya was engrossed in learning about mechanics in Dr. Kusno's lab when Dr. Kusno walked over with a communication device in his hand.

"Midori-kun, you have a phone call!"

"My phone?"

Although it was a bit strange who would contact him, Izuku Midoriya immediately took the communication device from Dr. Kusno and answered the call. He then heard the Grim Reaper's urgent plea for help.

"Master! The 'hair growth serum' you gave me has turned into a monster!!"

".......What?"
