On June 14th, 2035, the sky above Shibuya tore open, revealing a colossal spiraling galaxy. The phenomenon, soon dubbed “The Gate,” sent shockwaves across the globe. Despite the deployment of thousands of researchers and soldiers, no tangible secrets were uncovered—until humanity itself began to change.

One year later, humans started manifesting a strange new energy known as Mana, gradually turning Earth into a ground for supernatural awakening. But on August 15th, 2036, a winged entity descended from the heavens, followed by a black vortex that swallowed Raiyo Kureha and dozens of other citizens.

When Raiyo awakens, he finds himself in the Forest of the Abyss — an ancient territory between the realm of angels and the dominion of demons. Alone and disoriented, he uncovers a truth the human world was never meant to face:
The Gate was not an invitation…
It was a judgment.

Where dawn should have bloomed, the sky instead cracked open — slowly — like a cosmic eye becoming aware of our existence. A massive galactic spiral, silent and ominous, churned above Tokyo. People called it The Gate.


Governments panicked. Faiths either crumbled or grew stronger. But after months of fruitless investigations, the world began to breathe again. False alarm, they said. A cosmic anomaly. A collective hallucination.


Boxers could take down bears with their fists. Hearing, sight, and touch are just slightly better. And skin becomes marginally tougher, making it harder to bruise or cut.


And me Raiyo Kureha? I was just a freshly graduated high schooler, obsessed with sports, holding a gym membership and a blurry dream of the future.Until August 15th, 2036. The day everything shifted.


A divine—or perhaps demonic—figure. Black wings. Curved horns. A spiked tail. It hovered above the world, eyes brimming with disgust… and in that moment, we understood.


The Eye of the Apocalypse
