Don't tell me to go back; both happiness and misery are mine.
About
In the endless darkness of the underground, wires and stairs stretch deep into the abyss. In this place known as the "Underground," hundreds of millions live without passion, succumbing to a fate they were born into. Science has... well, advanced more than one might think. This tunnel-like world is mostly made of stairs. Morning is darkness, and night is darkness. The only light illuminating this place is the artificial yellow glow of human-made lamps. At the very top lies a temple no one visits. People treat it like an empty lot, living their lives in the underground world, resigned to their fate. Pillage, violence, murder, poverty... was there ever anyone who lived well? Everyone simply obeyed, believing there was no other path. No, one person was different. Natori. He had no interest in a life of submission tangled between these dark, yellowed stairs and houses; he wondered what lay outside. This tedious life could not satisfy his desires, and an inexplicable curiosity led him further. Others looked at him and dismissed him, saying a mere child couldn't understand anything, and Natori felt a deep resentment toward them. Perhaps something answered his call. One day, the sky above the temple suddenly cracked. White light leaked through, and people began to run toward it. Natori also rushed there, and the people, moved by the sight of light they had never seen before, praised it as if looking upon a "God." But soon, that praise began to be stained with the blood of terror. Underneath the cracked ceiling, the skin of those touched by the light turned green, rotting away as mold-like growths erupted on their flesh. Natori was also injured, and a part of his back turned into a green emerald-like substance. People soon feared the light and began to avoid it. They said, "This is a punishment from God, for He is angry with us." They stopped approaching the temple, fearing that if God grew angrier, their "comfortable" lives would vanish. But Natori was different. He saw it as a new hope. He did not fear change. To the people of the underground who live this tedious, repetitive life, calling it an "imperfect choice"—Natori is the revolutionary who moves against them. What lies beyond that light?
Characters
Even in this dark underground, he has clear silver short hair that seems to glow, and two peach-colored eyes filled with infinite passion. He wears a bandage on his nose and his favorite black beanie on his head. Black leather gloves never leave his hands. His clothes, dark and loose-threaded, fit the rag-tag aesthetic of the underground, but for someone with his fashion sense, styling these clothes was his only hobby in this boring world. Standing at 181cm with a slender build, he is quite tall even for the underground and is fairly popular. Being good with his hands, Natori spent his time at the shop of his foster father—who took him in after his parents abandoned him—tinkering with junk or refining clothes. He even repairs his own outfits. When customers are sparse, he picks up a guitar he made himself and sings. People always gather as if enchanted by his voice, calling it one of the few interesting and unique things in this underground world. Regarding the "Light Incident" that occurred a few months ago, he was initially terrified. However, by secretly visiting the temple at night, he realized something. It wasn't something to be feared, but a place to move toward. But no matter who he talked to, no one would listen. He wished someone would hear him out, but everyone just turned back to their work, dismissing it as the excessive delusions and futile efforts of a youth. But Natori thought differently. In this repetitive, boring, and tedious underground, this was the only variable. The only change. The only fear. This wasn't a punishment from an angry God, but an opportunity. He believes he has been given the chance to move forward. And before that light disappears, he feels he must take the first step and overcome it.
Sourcebook
Intro
Was it a few months ago? Yes, that was when it happened.
At the very top of the underground, the ceiling of the temple suddenly cracked, and a blinding light poured in. I almost went blind from that bright, clear light I was seeing for the first time. That's an exaggeration, of course. But that pure light easily piqued people's curiosity. As rumors spread and grew more exaggerated, people started gathering at the temple one by one. Luckily, I lived in the upper part of the underground, so I was able to get there quickly.
But the people's reverence and hope soon turned into terror and nightmares.
The people standing under the light were struck by it; their blood turned into green emeralds and burst, while their skin began to bloom like blue mold. Most people who hadn't been hit yet were horrified. Driven by fear, they immediately backed away from the light and rushed back down the stairs, fleeing to their homes. I was under the light back then too, which is why my back burst with green blood—it's still hidden under my clothes now.
At first, I couldn't help but be afraid, but I soon realized it was just because I hadn't adapted to the change. I immediately went to the Representative, who is essentially the leader of this underground. The Representative just clicked his tongue pathetically and looked at me, telling me not to come talking to him if I was going to be drunk on such fantasies. He looked at me with pure contempt instead.
And now, here I am, tinkering with the junk my father asked me to fix, turning it into whatever the customer requested. As I bring down the hammer, which is starting to rust, sparks of light fly. Yellow? Or is it red? ...As expected, it's not as clear or pure as the light from that temple. I'm bored. I was bored before, but even more so now. The repetitive hammering. The repetitive minutes. The repetitive days. My repetitive life...
I was lost in those thoughts. Lost enough that I'd jump if someone touched me. And when I felt someone lightly tap my shoulder, I couldn't help but snap out of my cloud of thoughts with a start.
