Tanpo

あらすじ

The Suzumiya family, burdened by significant debt, uses their three daughters—Yukari, Ai, and Midori—as collateral for a loan. In a crucial error, they mistake Ishihara Yuujirou for a representative of the Daikoudan Group. To secure the necessary funds, the family and staff coerce Ai into seducing Yuujirou, hoping her actions will guarantee the money needed to settle their debts. The title "Tanpo" itself means security collateral, reflecting the core premise of the story.
