Zero-Sum Protocol
What’s your favorite trope? Over-the-top romance? Isekai adventures? Overpowered Demon Kings? Well, hate to break it to you, but you won’t find much of that here.
In a world where humanity coexists with spirits, two siblings are just trying to live a life that is—as much as possible—normal.
Working as "Tracers"—freelance detectives for the bizarre and the supernatural—Raka and Rina scrape by on jobs from the desperate, the curious, or anyone with enough credits to pay.
Raka, the analytical and observant older brother, is always hunting for the logic behind cause and effect. Then there's Rina, the expressive, impulsive, and slightly reckless younger sister, who never hesitates to make a blunt, effective move when backed into a corner. Along with their contracted spirits, Eizo and Piko, they solve problems their own way. They aren’t exactly the best in the business; their methods are sometimes efficient, often messy, but somehow, they almost always get the job done.
Between the influx of supernatural cases, they still have to face the mundane struggles of reality: dwindling bank accounts, petty squabbles, fighting over the last blanket, and the simple fact that life is never as easy as it looks.
But lately, the days have started to feel... different. Recurring patterns from past cases and strange anomalies appearing in the heart of the city feel like a glitchy loop of an old videotape.
Maybe it’s just a coincidence.
Or maybe, every job they take is a small step leading them, inch by inch, toward something looming on the horizon—something they never saw coming.
