Seven years ago, on a rainy day — it was Eugene who gently cradled Navi, trembling inside a cold cardboard box.
From that moment on, Navi became his only companion. She stayed through the grief of losing his parents, through the loneliness of being left behind by the world, through every wound cut by cold words and colder glances.
Then a sudden accident stopped Eugene's world cold. Unable to face the crushing weight of reality, he retreated — locking himself deep within the labyrinth of his own unconscious, refusing to wake up.
To bring Eugene back to the real world, Navi leaps into his unconscious.
To pull the one who once saved her out of the darkness, Navi begins her fight — cutting through monsters born from shattered memories, battling her way back to him.
