It was an ordinary day in City Z, one of the most dangerous cities in the country, known for its high rate of monster or Kaijin sightings, which in the past had devastated the city. This forced the inhabitants to move toward the center, creating an abandoned area known as the Ghost Town, where two heroes from the association live.

Saitama, a B-7 rank hero in the association, has a simple appearance: he is bald due to his intense three-year training, his face is oval, and he has dark eyes. At first glance, he seems to have a slim build. The other hero who lives with him is Genos, an S-rank cyborg. Genos does not look human at first glance; he has a pale face, blond hair, eyebrows of the same color, yellow irises, and black sclera.

As usual, Genos was cleaning the house. While he was cleaning the bathroom, he heard the doorbell. He found it strange, as very few people dared to walk around that part of City Z, being an abandoned place frequented by Kaijin. Genos peeked out of the bathroom door and saw his máster, Saitama, in his pajamas, picking up a letter that had been slipped under the door.

"It's strange that the post office delivers mail here," Genos commented, surprised. "Who's it from?"

Saitama read the sender's name and felt a deep nostalgia, an unusual feeling for him.

"It's from my father," Saitama replied.

"Your father?" asked Genos, curious.

"Yes, my family lives in the mountains," Saitama responded. "It's a place two hours from here, although they used to live in the city."

Genos asked if his family had moved because of past events, but Saitama denied that this was the reason. He explained that they moved to take care of his grandfather, who was bedridden due to an illness.

"Since we didn't have enough money, my family moved in with my grandfather. I stayed because at that time, I was determined to work as an office worker," Saitama explained as he opened the envelope to read the letter.

As he read the letter, Saitama's usually expressionless face changed, and he sighed deeply. Genos, intrigued, asked what the letter said.

"My grandfather died, and they're going to have a funeral," Saitama replied. "I have to go to the house in the mountains."

Saitama sighed as he put the letter away and thought about wearing more appropriate clothes to attend the funeral.

Shortly after, Saitama dressed formally, and along with Genos, who insisted on accompanying him, they began walking along a stone path that led to his grandfather's house. Both carried a bouquet of flowers for the funeral.

"If I remember correctly, the house is after we go up this path," Saitama commented to Genos as they climbed the steps.

After about ten minutes, they reached the top of the path and found themselves in front of a postmodern Japanese-style house with Western touches. At the entrance, a woman between 45 and 50 years old awaited them, with some wrinkles, long black braided hair, dark brown eyes, and dressed in a formal suit.

"Mother," Saitama said, approaching the woman.

She looked at Saitama with narrowed eyes, confused, as she did not recognize him due to the changes his training had caused. However, after a few seconds, she recognized him.

"My dear son!" exclaimed the mother, hugging Saitama. Then, as she pulled away, she looked at him. "You've changed a lot. Don't tell me you're going through a second rebellious phase and shaved your head."

"It wasn't for that reason," Saitama replied with a forced smile.

"Then it must be because of your job. Stress makes your hair fall out," the mother said worriedly, then looked at Genos. "And who is the young man accompanying you?"

Genos introduced himself as Saitama's disciple, and the mother looked even more confused.

"It's a long story," Saitama sighed, changing the subject. "I don't see many people here."

"Well, they couldn't come. They said the place was too far away," the mother replied with a smile. "Well, come in. Your father and sister are in the main room, where they're watching over your grandfather."

Saitama and Genos entered the house, guided by the mother. Genos, interested in his master's life, took out a notebook and began to describe everything he saw, including the family. Upon reaching the room where Saitama's father and younger sister were, the latter was the first to stop praying and run to hug her older brother, much to the bald man's surprise.

"Brother, I missed you so much!" exclaimed the girl, a 17-year-old teenager with fair skin, a slim body, dark eyes, and long black hair tied with a black ribbon. Her hair was unique, as a section of it was dyed red.

The girl was wearing formal clothes for the occasion: a white shirt, a black skirt, black stockings, and black shoes.

"Hello, Nao," Saitama greeted, still surprised by the enthusiastic hug.

"Brother, you've changed a lot," Nao commented as she pulled away. "Did you shave your head to look more intimidating?"

"No, sis, things happened, and my hair fell out," Saitama replied with a forced smile. "But how did you know I'm a hero?"

Nao explained to her brother that she was very interested in the world of heroes and always followed the news about them. She even mentioned that she had seen him on TV.

"Though they barely show you, brother," Nao said. "And they talk very little about you, which annoys me. I've even had some online arguments about it."

Saitama was surprised to hear his sister and felt a sense of pride inside.

"Enough, Nao. Remember, we're at a funeral," said the father, smiling, as he stood next to Nao and touched her shoulder. "Let your brother and his friend pay their respects to your grandfather."

"Oh, I'm sorry. It's just that when I talk about superheroes, I get excited and forget the situation," Nao said, scratching her neck while smiling.

Saitama's father had a common appearance: a slim body, dark eyes, short black hair, and dressed formally.

Meanwhile, Genos analyzed Saitama's family, trying to find any traits that might suggest a genetic aspect to his master's powers, but he found nothing. He concluded that his master's family was very normal and simple. The most striking thing was Nao's hair, but to Genos, it was just dye.

Saitama left his flowers and knelt in front of his grandfather's coffin. He prayed for a few minutes and then stood up. Genos did the same. After the funeral ceremony, lunch followed. After eating, Nao went to wash the dishes, and Genos offered to help her, which Nao appreciated.

While Nao and Genos were washing the dishes, Saitama's parents talked to him.

"Son, we need to talk to you about your sister," the father began.

"About Nao?" Saitama asked. "What's going on?"

"Well, your father and I want to travel the world," said the mother. "So we want Nao to live with you for a while. We'll obviously pay you for it. What do you say?"

Saitama thought about it for a moment. Genos was already living in his apartment, but he could make room for his sister. After all, they would pay him for it, and it was better for her to live with him than with another relative or a friend.

"All right," Saitama replied. "Although there's not much space in my apartment, we can manage."

His parents thanked their firstborn for his response. Then, Saitama mentioned to his parents that he was surprised to know they had the money for such a long trip.

"Yes, it's a bit unusual, but your father got lucky," Saitama's mother replied. "He won a lottery prize, which was a large sum of money, and, well, taking advantage of this, he decided to go on this long journey."

While they continued talking, Nao and Genos started a conversation.

"What was your relationship with your brother like?" Genos asked Nao.

"He's always been a good brother; he helped me a lot. He also had the patience to support me with my homework and defended me from bullies," Nao replied, smiling. "I remember when they were bothering me, he stood in front of me, looked at those boys straight in the eye, and said, 'Stop right there, criminals! If you touch my sister, you'll wish you'd never been born.'"

Genos listened intently to Nao's anecdote. As Saitama's self-proclaimed disciple, knowing more about the caped baldy helped him understand him better. Nao continued sharing several experiences from her childhood with her brother, smiling as she recalled how Saitama would pretend to be a hero.

"I see, so Máster always had the intention of becoming a hero," Genos commented thoughtfully.

Suddenly, Genos's concentration was interrupted by the sound of a phone taking a picture. He looked at Nao, who was holding her cell phone.

"Sorry, I couldn't resist taking your picture," Nao said, smiling and scratching her neck. Then she added as she uploaded the photo, "I'm going to post it on a superhero forum... right, I also need to take a picture of my brother."

While uploading the photo of Genos, Nao asked the blond about her brother's feats.
