GyakuTen – Paradoxical Reincarnation
A saga of shadowed bloodlines and hidden truths, and self introspection...
This is a world where it will move your hearts.
📍 Setting: Neo Japan | Tokyo | Beyond | Set in the year 2100 +
All references here that relates to our book, worldbuilding, or quotes, are coded in:
"There are those who walk unseen among us—whispers in the wind, shadows in the crowd. In the age of concrete cities and neon skies, beings of ancient bloodlines still move beneath the surface. They are shinobi, assassins, spies, demis, androids, youkai, elemental majin, and shifters—each gifted with strange powers that bend the rules of our world."
Known only to a few, this hidden society thrives in secrecy, bound by myth, magic, and the weight of unspoken wars. Some live in silence. Some carry out missions in the dark. And some… are still searching for where they belong.
This is not the world you know.
This is The World of Introspection.
In Neo-Japan 2100, beings of ancient bloodlines live hidden among humans—powerful, ancient, and utterly alone. To survive, they must remain silent and safe. To live, they must be truly known and risk everything. In the world of introspection, being seen is the most dangerous power of all—but what does it cost to finally belong?
We let our characters grow from the silence that unfolds around them. We allow awkwardness to flow silently, which helps us better understand the characters and the world here.
