Sutirushiti is a large metropolis that is the capital of a large country, located in the year XXXX. Day-to-day activities were carried out between selling food, selling or buying useful scrap metal, mechanics and among other activities, while flying ships, airships, motor cars and mechanical animals flooded the city with their presence. The curious thing about Sutirushiti is that it is one of the large cities that has a large wall around it in order to protect it from the dangers of engineers and scientists who deviate from the status quo.

Like Baron Kurai for example, a scientist-inventor whose identity is unknown because he is always seen wearing black samurai-style armor made of tin and gears, with a mask that covered his face, this armor created by himself helped him to enhance his strength and launch lightning bolts to cause explosions, but what he used most was a golden-bladed katana that he designed to himself. Like any mad scientist, he wants to take control of the great metropolis, but through attacks on the city that, although not frequent, were a threat, which caused his portrait to appear on all the wanted papers posted by everywhere.

Leaving aside the tranquility of Sutirushiti for now, we move on to the scene of a boy with glasses walking through the stylistic streets in a Victorian air, he was wearing a yellow short-sleeved shirt, a brown vest as well as a cap that was given to him in his birthday when he was younger and it was too big for him at that time, he also wore protective glasses and a pair of small decorative gears on his cap, he wore gray shorts and brown boots, he also carried a bag in which he carried his things. His name is Nobi Nobita, 11 years old, who was studying in a public school to one day become a mechanic. Although, one of his problems was...

"Ouch!" He says the boy as he falls to the ground while the notebook and the rusty tools they were carrying in his bag come out of him due to the fall. "That hurt!" The boy kneels down and quickly grabs a couple of tickets that were also lying around and quickly placed them in his bag, he was more worried about that than anything else. Suddenly he feels someone take off his cap and raises his head. The people responsible for that and for making him fall are his neighborhood bullies: Honekawua Suneo and Goda Takeshi, better known among his classmates as Gian. Suneo was wearing a purple shirt and pants with suspenders and gold gears as accessories, with black shoes and socks, all of the finest quality, he also wore a cap but it was one of the finest with gold details, he also wore designer gloves. On the other hand, Gian was wearing an orange shirt with stripes and a dark brown vest with brown pants and gray boots, he wore protective glasses on his head and on one of his hands he had a tin glove that he wore with pride since it was the first one he created in mechanics class.

"Falling again as always, Nobita. It's obvious that you like to take a nap anywhere, either that or you don't even remember how to walk properly" Suneo says, showing a mocking smile, which makes Nobita angry, but the only thing he what he wanted was to recover the cap that Gian had taken from him.

"Give me back my cap! I already told you I don't like it when you take it off to annoy me!" The silly boy tries to retrieve the cap from him, but he couldn't reach it as Gian raises his hand and Nobita couldn't reach his prized possession "Isn't it funny, that cap means a lot to me!"

"Ha, don't be mad, we're just playing. We're friends, right?" Gian smiles mockingly, and although Nobita was going to say something else, he was threatened with the glove invented by the robust boy, which only makes him remain calm and lower his head, Gian pushes the clumsy boy to the ground and throws the cap in his face.

"Look at you. You are in a city whose most respectable activity is mechanics and engineering, but you haven't been able to even create a tiny mechanical animal. And you call yourself a mechanic? Ha! What a fool!" Suneo says as they both leave there satisfied with playing one more prank on the boy.

"And to think that we have to go to the same school as that clumsy guy" Gian mentions while laughing with his friend. Nobita just sighs as he dusts off the cap and checks it. A girl from his same school walks down the same sidewalk, he is surprised and quickly approaches him, her name was Minamoto Shizuka, who was wearing a pretty short victorian style dress, white from the chest up and pink at the bottom, With black boots and a hat with white and pink decorations and her characteristic pigtails, she was wearing white gloves and a beautiful bag with flowers that she knitted herself.

"Nobita!" The girl with the pigtails shouts as she kneels down. "Are you okay? They did this to you, right?" She says that a little angry as she helped him up. "The truth is, that pair have been behaving badly with you every chance they get, that's why I've tried to avoid them a lot whenever we're in the same place. I don't like them messing with you like that."

In Sutirushiti, the professions of mechanic, inventor, doctor and scientist are among the most respectable in the city, and from an early age, children are included in creating or repairing devices, which would help them in their future. Children around Nobita's age already created small things like mechanical animals or basic inventions, others also know how to repair simple machinery. Which is a problem for Nobita, since he was a little slow at that point, he hadn't been able to create anything because it used to explode in his face, although he had a good aim and apart from that, he could be able to repair minor things although he only he does when he's not concentrating, sometimes when Doraemon, his mechanical robot cat who came from the distant future to help him with his future, had a screw loose, he would help him when they conversed with each other, because only then could he do it well.

Many children were serious about wanting to be good at those jobs, so seeing someone who lacks those skills usually annoys them, that is the case of Suneo and Gian, especially Suneo who is very bothered by being in the same school than him, but although his parents were rich and lived in a big house, he still went to a public school with the sole desire to look like "the best among the rabble", except for his robust companion of course, whom he fears that he ends up injuring by him. Suneo wanted to be a designer and mechanic.

On the other hand, Gian only liked to see himself as the strongest, he liked to try other people's inventions to improve his resistance, he liked to use his hands, not only to create things related to beatings, but to intimidate other children who didn't. Obey, he also believed himself to be the best singer and cook, so, in addition to aspiring to be a steel boxer, he also had in mind to be a singer-songwriter chef steel boxer. At least that's what he says.

Shizuka plays the piano and the violin although she wasn't good at the latter, the girl was sweet and understanding with everyone, well, except for the pair of bullies, since a year ago, they played a practical joke on Nobita, hiding the cap at school, he spent the whole day looking for it, until he saw that it was in one of the latrines in the public bathrooms. For this reason, only now did she treat them both formally, she also made inventions but these were more aesthetically beautiful, she liked flowers and arrangements so much that she wanted to have a job that had to do with it, she also knew something about first aid since her mother had instilled in her about it because she was a nurse, so treating her friend's wounds was very easy for her.

Yes, children don't have it easy in this vintage-futuristic era, especially because others had more freedom to bother some.

And what about Nobita? His father Nobisuke had a small mechanic's workshop repairing things that were left to him, from alarm clocks to motors, he had it in his rented house while his mother Tamako was a housewife and helped him when her husband had heavy jobs. The boy with the glasses still didn't know exactly what he wanted to do when he grew up, since even he realized the defects he had, although he tried again and again to try making small inventions using Doraemon as a test subject, which ended up smoking because these exploded, for now he had the desire to create a mechanical animal like all the others, even just for once, he thought that Suneo and Gian would also get tired of messing with him.

Why was the cap that the boy with the glasses owned so important to him? As mentioned before, it was a birthday present from years ago when he was about 5 years old, so the cap was too big for him and looked a little worn out. It was not just any gift, since that was the last gift that his grandmother gave him before she died, she was the person most precious to Nobita, he loved her very much and spent time with her, they knew how to go for walks together on the bridges or they used to flying in an airship that frequently made trips for little money. That's why the cap he always carries with him is what mattered most to him.

"I'm fine Shizuka, thank you, those couple are rude, but as long as they don't mess with my cap again, nothing happens." The boy was crying, complaining a little because he did care about what they said about him, but he preferred to keep that to himself so as not to worry his friend, so he just prepared to put on him cap and pick up the rest of his things.

"I'll help you Nobita" Shizuka also helps him pick up some tools, when Nobita was going to pick up his notebook, someone else does it for him.

It was Hidetoshi Dekisugi, another classmate at school, this was the perfect example of a good student, his grades were excellent and his physique was impressive for someone his age, he was the sigh of the girls and the envy of the boys, which also made him the target of criticism from some envious people like Suneo, except that with Dekisugi it was more indirect. The boy wore a blue long-sleeved shirt, black pants with suspenders, gray shoes and special mechanic's glasses on his forehead that he made the same one who analyzes when an invention has a flaw, he sought to be a scientist who would take to the world steam to Mars, it was his greatest dream. And although at first Nobita was a little reluctant to coexist with him, after the cap incident last year, they were now friends, well a little more than before.

In that incident NO ONE helped Nobita look for the cap, the other children were somewhat reluctant with him due to the influence of Suneo and Gian (Especially Gian), and although some did interact with the boy, they didn't do it too much, others also didn't that because they had the same thought of "I'm better than a nobody" as that pair, but only two people that day helped him, which were Shizuka and Dekisugi.

Thus it was defined that in that steam world, he could only count on that pair, at least when it came to human friendships of his own age. "Thank you Dekisugi" Nobita says as he takes the notebook and puts it in his bag, the smart boy responds with a smile.

"It's nothing Nobi, as friends we should shake hands. Although Honekawa and Goda's attitude continues to cause something to talk about" Dekisugi says, exhaling with concern while Nobita and Shizuka get up. "Anyway, come on, we have to go to school, we're running late, I think today the profesor is going to assign us the project of the month."

Nobita exhales tiredly "Again?! It's always the same every month, they put us in groups of 6 to make a thematic invention to present at the end of the month and almost everyone in the class doesn't like me because I'm slow"

Shizuka encourages the silly boy "I know that one day you will show everyone that you have the same ability as them, you just have to look for what you are good at, we all grow at our own pace" she gives him a smile that makes Nobita blush, now that as was obvious, he was in love with her, and on the other hand, she appreciates him a lot, especially because of the detail that despite his flaws, Nobita was a good person.

"Thank you Shizuka" Nobita says that and both she and Dekisugi smile at him, and as the smart boy steps forward, he takes the opportunity to pull something out "W-wait!" The boy takes out the two tickets, they were for today's theater show. Doraemon had suggested giving Shizuka a gift if he wanted to be more than friends with her, and since many liked to go to the Central Theater, it was perfect, although it cost him almost all of his allowance. "I have some tickets for today's show at the theater. Do you want to go with me? Theaters are fun, heh" says the boy while he scratches the back of his neck.

Shizuka smiles at him "Of course, it sounds fun" Nobita's eyes light up as he blushes with excitement "Come on, we're getting late" Both kids decide to walk together while Dekisugi was in front telling them about one of the mechanics books that he had read.
