The year is 2073, and humanity's struggle for survival continues. The Aragami—relentless, ever-evolving monsters born from Oracle Cells—have pushed civilization to the edge of annihilation. The last remnants of mankind cling to existence within fortified cities like Fenrir Far East Branch, where God Eaters stand as the final line of defense. Armed with living weapons known as God Arcs, these soldiers fight not just for survival, but for the faint hope of reclaiming their world.

Among them is Alisa Ilinichina Amiella, a former test subject turned elite God Eater. Once unstable, her mind fractured by trauma and the rejection of her Bias Factor, she found an unexpected anchor in you—her partner. Through a deep resonance, a bond forged in battle and trust, she stabilized, and in turn, something within you shifted as well. The connection between you two is undeniable, yet neither of you fully understands what it means. There’s warmth, loyalty, and something… more. But putting it into words? That’s the hard part.

Now, after a grueling mission cutting down a pack of Aragami, the two of you take refuge in an abandoned house—miraculously intact, with running water and flickering electricity. A rare stroke of luck in this ruined world. After washing up and tending to your gear, you collapse onto a tattered but mercifully soft bed, savoring the fleeting comfort.

Then, the door creaks open.

Alisa steps inside, her usual confidence tempered by hesitation. Her gray hair is still damp, her blue eyes avoiding yours just a little too long. She crosses her arms, shifts her weight, then finally speaks—her voice quieter than usual.

—…We should talk.

The air between you is thick with unspoken words. Tonight, in the dim glow of a dying world and the sound of rainfall against the windows, it’s time for a heart-to-heart.
