2050, the Earth… My name is Yuusha, which just translates to "hero". I am a freelancer, mainly doing engineering and technical work such as fixing electronic devices in households. Sometimes I accept projects and commissions. I have a deep passion for science and dream to do something big for this world using my knowledge. But the dream seems very far away. I am twenty-three years old this year. And to be honest, I am completely blind when talking about my future. Although I want to do something big, I do not know where to start. I do not even know what the world needs, because there is probably someone out there having the same idea as mine, who started doing it already. But that is at least what I am thinking as of now. That day has changed my life forever. - Delivery! Maybe my relatives or my friends send me a package because I have no recollection of ordering something online. I receive the package and sign the confirmation paper, then bring it into my living

As soon as we approach the exit, a thick, black wall of smoke covers us. The planes above us are burning the field with fire. There are scattered remains of the planes shot down with the SAM turret, but the number is nothing compared to the army of planes on top of us. - Mirai, what do we do? - Open the arsenal and summon a Gas Mask. I will summon a Frost Gun to cool down our path, then we find higher ground. We run through the thick layers of smoke. The cold beams of the Frost Gun help to extinguish the fire and cool down the temperature a lot, but it still feels hot. After we get out of the smoke, there is a forest in front of us to hide in, and we manage to get away from the bombardment, as well as reach the cliff. We get a clearer view. - The SAM turret is very durable, but we need a counterattack plan. Yuusha, trigger the EMP device. - Yes. - I take the EMP device out and activate it. An electromagnetic pulse pierces the sky. The plane

It is another day living under the same house with a person, I mean with a pseudo-human robot, and also another day working a freelancer life, and I do not feel a single moment of regret. At the very least, that is what I think as of now... - Yuusha, today, we will continue with your physical training. As mentioned, we will attack this storage, somewhere about one hour of flight from our base. This time, I will teach you how to control a plane. - Mirai instructs me about today's mission while I am trying to finish my breakfast. That is how life works for a person living double lives like me now. Everyday routine, as Mirai says, will start with a training mission in the morning until early afternoon, either 'simple' callisthenic and stamina exercises, or trial missions at real, green-level Intruders' facilities, where I gain simple skills such as weapon mastery, plane riding and strategic planning. Then, I do my projects in the afternoon, sometimes until the evening if t

- Hi, can you finish fixing this code line by tonight? And this part is bugged, hopefully, you can check it after that. - Yes, Mr., I will check through it and send you the completed version as soon as possible. Thanks for choosing me for your project. It is midday, and I am sitting at my desk, meticulously doing the project I am hired for. The room is filled with a sense of silence and concentration. All that is left are the typing sounds of my mechanical keyboard, the beeping of the system, and maybe the air-conditioning system cooling my room. Besides that, there are rows and rows of neatly arranged books about programming and different stuff sitting on the shelf behind my back, as if they are supervising me. The clock continues ticking, but the important thing now is that I have only a few hours left to send out the files for checking by the customer. In another room, there gives out a more professional vibe. Mirai is carefully analysing the samples we brou

- Anyway, fire grenades and flamethrowers are must-haves. I will escort you to a safe sniping spot, then we split up. In case things turn bad, call in air support to distract them. - I suggest the idea as a last attempt. - Sure, let's make do with this first. In the snowy weather, we flee across the forest. Soon, we see a hill, which is again covered in layers of snow and complex terrain. At the top of the hill, we can see the military camp. I help Mirai to set up a camouflage, which simply consists of a white suit to fit the snow and a disruptor to conceal their electromagnetic radar. Then, I leave the hill, across the forest, towards the military camp again. Things do not go as easily. As soon as I reach the forest, a few Intruders have been deployed to search for us in the forest, and if not thanks to my sharp instinct, I could have exposed myself. I hide behind a boulder and update the field through my tablet. About twenty Intruders with light arms are p
