1. "Double Payback! A New Hero Rises Against Corrupt Bosses!! Can He Recover 500 Million? Battles Among Wives in Company Housing — Ambition or Friendship?"

Hanzawa Naoki (Masato Sakai), the loan manager at Tokyo Chuo Bank’s Osaka West Branch, joined the bank during the bubble economy. Twenty years later, he is a central figure in its operations. His colleague and close friend since joining, Tomari Shinobu (Mitsuhiro Oikawa), often advises and supports him. At home, his cheerful and honest wife Hana (Aya Ueto) stands by him. One day, Branch Manager Asano (Kanji Ishimaru) orders him to secure a 500 million yen loan from Nishi Osaka Steel—with no collateral. Though this brings the branch its first excellence award, the company collapses three months later, revealing massive hidden debts and fraud. The bank loses the entire loan, and Asano shifts all blame to Hanzawa, backed by Executive Director Ōwada (Teruyuki Kagawa). As internal power struggles flare between old factions of the merged “mega-bank,” Hanzawa vows to recover the lost money—his only way to survive as a banker.
