Fourth Dimensional Bank

"What if your lifespan was the only currency left to spend?" Zetsu is 22. Jobless, purposeless, and drowning in regrets, he’s become a ghost haunting his own life—breathing, but not living. Until one rainy night, an email appears on his phone with no sender, no address… and one terrifying offer: A second chance—if he’s willing to trade his remaining years. When he clicks [ACCEPT], Zetsu awakens in Tokinomachi—a strange city suspended outside time, where lifespan is money, laziness kills, and your only worth is how many years you have left. Here, every second ticks against you. Work buys you more time. Doing nothing? That’s how you die. And when your time runs out, Shokutai comes—the reapers who execute those with zero balance. At the heart of this cruel system lies a mysterious institution: The Fourth Dimensional Bank, a place that loans you time… at soul-crushing interest rates. But the deeper Zetsu dives into this merciless world, the more he realizes—something is very wrong. Why do the clever die young, while the ruthless survive longer? What secret does the Bank truly hide? And most of all… who is really pulling the strings? In a world where time is power and life is debt, Zetsu must do more than survive— he must break the system before it breaks him.
