-(Last P.O.V: Nobita)-

"Come on silly boy, wake up we have a lot to do!"

How long was I unconscious? I fainted from the pain of the blow I received, but I'm starting to feel someone patting me on the cheek, I'm slowly regaining consciousness, my vision is returning, I was back in the command console room of the black airship, I feel like I can't move. I see that my hands were tied behind my back and my arms were tied, not only that, my legs were also tied, I don't have my protective equipment or guns either, I can see them under the console.

I see the place that was behind the large display case in the console room, it was... Was it the outside? I had already seen it once when I was traveling with my grandma on the airships, but seeing that it's still as deserted as before made me a little nervous. Just thinking that this was what the great walls hid due to the wars that took place, scared me before and still scares me now.

I see the baron's right hand next to me, she was the one who was slapping me on the cheek to wake me up, I only see her nervously while I try to free myself from the ropes but no matter how hard I try to move I can't do anything "Don't waste your strength, you won't be able to get rid of those ropes"

I hear Baron Kurai's voice, he was without his helmet, he is behind me, as the command chair was swivel, he turns it in his direction "I hope you are comfortable Heartbreaker, you will soon witness an impressive spectacle. We are close to Sutirushiti, and when it's time for the awards ceremony, that's when we'll dominate everything." He just looks at me with that sinister smile that disturbs me, it's the same one from that day in the warehouse.

"It's a shame that the plan they involved you in failed. But that allowed me to see your talent, I knew from that day in the warehouse that your potential was that of a living weapon, if you were on the right side of history, you would win. After all, you are my creation."

Why does he insist on that? It seriously bothers me that he calls me that and also says that I'm his creation. "Stop calling me Heartbreaker, that name is horrible because it reminds me of everything I went through because of you and that moment when you wanted to corrupt me! I'm not a number, I'm not an experiment or a weapon, I'm a human, my name is Nobita, not 807, not Heartbreaker! You didn't create me, I don't owe you anything, you're just a monster who wants to use Sutirushiti as a giant laboratory!" I say all this with tears, I'm already fed up with him, I had already gotten rid of a couple of bullies to fall into the hands of another.

"I guess you're in denial about the fact that you owe me your life, Heartbreaker. But it's understandable, we have time, so... What if I told you that the heart that's now beating in your chest is actually MY invention?"

WHAT DID HE MEAN THAT MY HEART IS HIS INVEN...?! Obviously that's a lie! "That's not true, Seiya and Melia's grandpa was the one who created it!"

"In part that's true, but with MY plans and details, some time ago after blowing up my laboratory 50 years ago, I decided to return to the world of mechanics and science with a mask and a different identity to develop the foundations of this plan that you see now. You know how good I'm at hiding my identity, you've already experienced it." It's true, he really fooled us all when he disguised himself as Professor Yamada, not even Dekisugi could be able to discover it.

"We both worked on a project years ago, my idea was a special motor, one that was capable of being used by the human system, not like the common mechanical prostheses used today that can be connected by limbs. I'm talking about a true engine that is capable of giving to a human the ability to power even the greatest inventions, the invention which I named: Mechanical Engine." The unpleasant man only smiles in such a macabre way that it even made me shiver more

"Yes, it isn't a very original name, sometimes geniuses have their flaws, but that invention wasn't only going to be a unique energy generator, but at the same time it could be a weapon if used correctly. I created the plans for the engine, how to place it, how to make it work with the human system, how it should be used. You have no idea how many cardiology and anatomy books I had to study to create the perfect plan for the Mechanical Engine, but for a superior genius like me, those types of situations were like a walk in the park."

Seiya is right, this man is very self-centered. Suneo falls short compared to him "Using the alias Professor Hideki, I became a colleague of Professor Hirano, the former owner of Suchimu Corp. My goal was to use the professor's talent to create the Mechanical Engine and use it as I please, in When he saw my plans and details he was fascinated, so we got to work, without knowing the true purpose of the invention: My own benefit."

Did Professor Matsuyama trick Seiya and Melia's grandfather into helping him build an engine for his own benefit? Has he just dedicated all this time to using people for his own benefit? "I was planning to incorporate the Mechanical Engine into my plan by disappearing with the invention as soon as it was finished, but it seems that someone realized my false identity since the police began to investigate me, which forced me to have to disappear from the human eye again by pretending taking a break from work with the invention's progress almost close to halfway done, so I thought I'd wait for him to finish it for me to claim it and use it on one of my minions, after all it was MY idea, MY plan, MY creation..."

The baron just turns around, I can feel a thoughtful change in the tone of his words, so even though I couldn't see his face, I felt like he was starting to get upset "But when I called him once pretending that he was going to come back... That fourth grade teacher told me that he hadn't only finished the engine, but that he tested it and that it was a failure. That made me feel frustrated, I felt like I had failed for the first time with an invention, but there was no turning back, I had to continue with the original plan of taking control of Sutirushiti. So as much as it hurt me, I gave up with the engine and continued with my assistant to put together the plan."

The baron begins to walk from one side to the other, even if it's just a little bit. Now I can see his frustrated face, which is just as creepy as that horrible smile. "Years passed until the current time and I even forgot the existence of the engine..." He just looks at me. Please stop looking at me, it makes me nervous! "Until you showed up. You showed up just to give me the answer to something I thought I had lost. And the only thing I had to do to reveal the truth was cut you! That day of the incident in the great hall, my goal was to capture Dr. Keta who would attend that event as a judge, he is another of Professor Hirano's colleagues, that was in order to get information from Suchimu Corp and make him work for me like the others. Who knew that plan would be interrupted by someone who played the hero?"

"You wanted to hurt people and you tried to hurt Shizuka!" At that moment I receive a slap from the baron's right hand, even so, what I said is true. They were going to hurt a lot of people there!

"Don't talk back to the future leader of Sutirushiti, Heartbreaker, learn your place! Don't forget that it's thanks to him that you have that power!"

I don't owe that guy anything! Everything I've been experiencing is his fault! Why would I have to thank him for that?! I just can't say anything else, I don't even know where Doraemon is, I know he must be on the airship, but I don't know where he will be, if I ask I'm sure they won't tell me and they'll slap me again. It's possible... It's possible that they brought him in to blackmail me...

And... It's working, until I don't know where he is, I can only tear up and hang my head, I feel trapped here... I feel alone... I feel vulnerable without my best buddy with me...

"When I heard what happened to you on the radio, there was no doubt that those guys used MY ENGINE, so I sent Katami to not only get the documents of that absurd plan with which they wanted to arrest me, but before that happened, I put her to find out more about the Mechanical Heart that you have and confirm my suspicions. Professor Hirano was the one who lied to me saying that the invention failed, but in reality it worked, and created 4 more similar prostheses for other parts of the body, not only that, But he modified the original design of the engine to turn it into a heart and thus obtain subjects for the prostheses. Can you believe that I thought that one of MY INVENTIONS had failed?! Me, who am a strong and superior genius!

"Now that I think about it, I think it was also the fool who made the police investigate my false identity. But that doesn't matter now, I know that there were many guys before you Heartbreaker, when Professor Hirano's son assumed his legacy, he must have been unaware the potential of the heart, so he used it as another special prosthesis."

"Being the most complicated organ to adapt, I'm not surprised that it hasn't been compatible with adult human beings. I understand that, but what I can't understand is that of ALL the adult human subjects..." The monster only approaches me at me while he puts his hands on the arms of the seat with a frustrated smile that only made me pale, this guy is crazy, I don't want to see his face anymore

"WHY DID THE ONLY ONE COMPATIBLE WITH THE ENGINE END UP BEING A STUPID 11 YEARS OLD BOY WITH SO MANY DEFECTS?!"

The way he yelled at me just made me shake and cry, I'm face to face with the person who complicated my life 4 months ago, it's like my old self took possession of me for a moment by yelling at me like that, it's like I feel like at any moment he could get rid of me. I think Mr. Hirano and Dr. Keta didn't know this was going to happen, I don't think they hid the fact from me that they put the invention of a villain inside me.

I don't think they wanted to hurt me too. I-I trust Seiya and his family!

I only have to close my eyes and look to the side, I want him to stop looking at me "But... Like every naive child, you too can be molded, Heartbreaker. I created you because I was the one who gave you the opportunity to get this power, If it hadn't been for my hand, you would still be the weak and stupid boy who couldn't even defend himself against a couple of spoiled classmates who knew the meaning of power. If it hadn't been for my plans and my idea, you would be in a grave now while your pathetic parents and friends cry over that."

I'm just... I'm just letting him insult the people I love in my presence, more than afraid, I was starting to feel irritated, he talks about death as if it were nothing! Doesn't he have even a shred of empathy?! "You now have the power, a power that you now know how to handle, but that needs to be polished, needs to be perfected. And who better than your creator to do that? This is your last chance." With my eyes closed I only feel less weight, for which I open my eyes and look at him again with a rage that was beginning to replace fear.

"Join my ranks, Heartbreaker, if you really want to stop suffering anymore, so you can be free of that old-fashioned and useless empathy that binds you so much to being weak and mediocre, weakness will be the reason why Sutirushiti will fall. You are an as, you don't need anyone, just your power and I can make your power become something that will show strength, you can be better than those who convinced you that they do the right thing."

"Your parents may have given you the life, but I made you better, and if you accept, I'll make you superior. Those teammates you have who claim to be equal to you just because they have unique prostheses only use them to help the weak, it's a waste. BUT YOU, you aren't like them, we aren't like them. We have the power to prostrate the world at our feet, because this world belongs to the strong, because as I said before: THE WEAK DON'T DESERVE MERCY. "

-(Leaving the last P.O.V)-

At the same time that the Black Airship event was happening, in the now temporary shelter, everyone fell silent upon hearing Dr. Keta's story about the Mechanical Engine, which although it was the same as the story told by the steel monster, was from the point of view of Professor Hirano, Seiya and Melia's grandfather. "So... grandpa had discovered that Professor Hideki, the one who became his colleague, was an imposter when he was working on the Mechanical Engine, and that's why he notified the authorities?" Melia says

"And that after that he discovered that it was Professor Matsuyama and that he lied to him on that occasion that he called him saying that the engine was a failure just to prevent him from coming back for it and prevent it from falling into the wrong hands so that after that he could transform it in the Mechanical Heart to then create the other 4 mechanical prostheses for its dual purpose?" Mia says

"And Professor Hirano transferred the special prosthetics to Mr. Hirano when he took over Suchimu Corp, including the mechanical heart that has a great power of energy that is capable of reanimating even huge inventions while launching that same energy as attacks in conjunction with the STEAM Experiment plan, to use them to stop Professor Matsuyama in addition to creating miraculous prostheses for the future, and the only one who told you the true identity of the heart was you doctor?" Dr. Keta nods to what the intern asks, leaving Olivier pale, who sits on the floor.

"Why didn't my father tell me something so important? That prosthesis was the Baron's idea... And I put it on a child" The poor man can't help but put one of his hands to his face "I put a dangerous prosthesis on a child, his parents trusted me his life and I... I thought... I thought it was just a prosthesis that accumulated energy to keep the body alive and nothing more if I had known from the beginning the subsequent risks that the heart carried, I would never have suggested it on the day of the incident, I didn't know at that time that it had functions beyond a normal heart, that is why I had suggested to Nobita that he not get involved in this if he didn't want to... And now... That monster has him"

"Dad" Melia puts her hand on her father's shoulder "What's done is done, don't feel guilty about all this, you wanted to give the heart to Nobita because you are a good person, you wanted to save his life. You didn't know that grandpa had hidden crucial information about the prosthesis, you helped our friend to continue living, if you hadn't he wouldn't be with us. Nobita wanted to enter the program because he saw this as an opportunity to prevent more people from suffering what he suffered. And if you still decide to tell him this background, I don't think he will hate you, because he was so happy to live again, it was noticeable when he woke up from the coma."

"Your father made me promise not to tell you this until the day of the mission, he confessed everything to me before leaving because it's possible that he felt partly guilty for having created something together with the baron and sought to make amends by preventing it from falling into the wrong hands, I'm sorry I didn't tell you this before, but I take my promises seriously, you saw it in the incident when I promised to help that boy and his family" says Dr. Keta. "There is no need to grieve now, first we have to stop Professor Matsuyama, when that happens, we will all be free, including his own invention, we have a mission of years to finish, apologies will come later."

Mr. Hirano stands up making everyone perk up "Fine, but I'll tell him the truth, after all, I have a contract with his parents when they put his life in my hands, I should be the one to be direct, at least with he deserves to know. Hikaru. How are we doing?"

The intern smiles showing a small panel of homemade parts and gears with about three buttons. "It's ready, just give me the signal to do it."

"I suggest doing it when it's time zero, the Baron is very confident and we will make his entire world fall little by little, we will use a radio to do it, Dr. Keta will be in charge of that panel, they need you up there. That's why Mia, Melia and you will go upstairs to assist the other half of the Sutirushiti Task Force for the real counterattack. And I trust that Seiya will be able to get Nobita and Doraemon out of that predicament, I know they will be able to get out of there."

Mia nods as she clenches her fist. "Okay sir, we have to put an end to this. The Assistance Phase is back in progress."
