In an era when the abyss swallowed the world, I was abandoned in the rustiest corner of human defense. They called me trash until I was forced to climb into that mech - codenamed Mourner.
They said it was a tomb and a monster. They were right.
The moment the nerves connected, the biting cold and world-destroying hunger crushed my consciousness. In the broken memory, the stars are burning and the steel is wailing. An overlapping whisper screamed deep in my bones: "Hungry... Give me... Flesh..."
I became a symbiosis of monster and trash.
Driving this biological mecha that "eats", evolves, and looks increasingly more ferocious, I hover on the edge of humanity. Every time I devour an abyss monster, I become stronger and closer to madness. The senior officials of the Seventh Great Wall regard me as a terrifying weapon. The secret research institute "Black Tower" is eager to dissect and study me. Even the teammates around me are struggling between dependence and fear.
But on the front line of this abyss of despair, I discovered that the hunger of the mourners may not only be for destruction. The shattering truth points to an ancient betrayal, and the painful reverberation deep in the mecha whispers of the possibility of redemption.
When a larger conspiracy tears apart the defenses, and when the abyss reveals its real fangs, my "old buddy" and I must make a choice: Should we become monsters swallowed by fear, or should we chew out a glimmer of dawn for humanity in the midst of endless hunger?
This is the story of the driver and the mecha going into the abyss together. We are all imperfect, we are each other's fangs and armor.
