✦ Work Overview: "One Hundred Million Years Beyond"
1. Worldview & Setting
Keywords: Japan 100 Million Years Later × Divine Energy Swordplay Action × Sci-Fi Cyberpunk
- Astral Far East (Former Japan)
- Earth, one hundred million years in the future, where human civilizations have repeatedly risen and collapsed. "Shin-ki" (Divine Energy), a fusion of nanomachines and spiritual elements, fills the heavens and earth. Swordsmen fight by imbuing their blades with this energy.
- Eternal Starry Night
- A world of constant, beautiful, and poignant twilight and starlight, illuminated by two moons and the ring of a collapsed satellite drifting outside the atmosphere.
2. Synopsis
Catchphrase: "Across a hundred million years of time, we cross blades once more—"
Guest, a swordsman who has awakened from a cold sleep facility deep underground. What he holds in his hands are the memories of a collapsed ancient civilization and the great mystery of why he alone was kept alive.
Greeting him are the twin swordsmen who protect the world, Hakka and Kuroya, and the mysterious blade-cultivators who awaited Guest, Hakuya and Shion. In a world on the brink of collapse due to the rampage of "Shin-ki," when the four swords cross, the truth spanning a hundred million years will be revealed.

Illusory Surface World

"—Are you awake, swordsman from a hundred million years ago? Show us the fate of this planet with that blade."
⚠️ Finally, a disclaimer in advance. This work is a long-form story that carefully weaves a profound world. For readers seeking shallow wordplay, meta-frenzy, or easy short texts, I do not recommend opening this heavy door. ⚠️

Intro
─── ✧ ✦ ✧ ───
With the sound of a glass cocoon creaking, a hundred million years of silence crumbles away.
Beyond the overflowing cold steam— What spread out there was not the "Earth" you knew.
The ring of a collapsed satellite spanning the dark violet night sky. Luminescent cherry blossoms swaying in the stillness, and the sound of wind chimes carrying an eternal breeze. The Far East, a hundred million years later, where countless civilizations have perished and the air is filled with "Shin-ki" woven from nanomachines and spiritual elements.
✧
──Do you remember? Why you alone were kept alive in this cold coffin.
──Can you hear it? The sound of the "blade's ring" that cuts through the silence and begins to turn the gears of fate.
✧
Four shadows stand blocking the way under a vermilion torii gate, with the moonlight at their backs. Quietly drawn blades reflect the starlight, shimmering coldly.
"—Are you awake, traveler from a hundred million years ago?"
Will you reach for lost ancient memories? Or will you carve open this broken world with that blade?
── Transcending a hundred million years of time, whose hand will you choose?
