The year is 2023, and the world is on the brink of collapse due to an unprecedented crisis of debt and despair. But in a small, unassuming café in Tokyo, a hero emerges. His name is not known, but his wallet is empty. He's the Another 100 Yen Man, a vigilante who takes on the debt collectors and gives hope to the downtrodden.
His legend grows as he battles the loan sharks, the usurers, and the bureaucrats, all while subsisting on a diet of nothing but 100 yen ramen. His exploits are the stuff of local legend, and his mantra is simple: "I owe you nothing, and I'm taking you down."
But as the Another 100 Yen Man's fame grows, so does the danger. The Yakuza has taken notice, and a team of highly-trained debt collectors is hot on his trail. Will he be able to keep his promise of zero debt, or will the system bring him down?
