A high-stakes psychological thriller where losers gamble their lives to erase massive debts. It’s a brutal look at how far people go when cornered by society.
Why it's similar: Both shows focus on the extreme desperation of men at the bottom of the social ladder. Like the boys in Cell 2-6, Kaiji must rely on temporary alliances and sheer mental fortitude to survive a corrupt system designed to crush him.
Power comparison: Neither show features supernatural powers; instead, the 'power' lies in psychological resilience and the ability to outthink a cruel opponent under life-threatening pressure.
Why watch after Rainbow: Watch this if you loved the feeling of being trapped in an unfair situation and want to see a protagonist claw his way out.
