As Iron Town comes under attack by Cyber Emperor due to Kintetsu's family failing to pay off their debt, Kaito confront's the company's president, Deborah Kizaki, who claims to have purchased Iron Town and plans to turn it into a theme park. Kaito puts his Enter the Gold suit on the line to win Iron Town back from Deborah in a Hero Battle scheduled for the next day. As Deborah does a background check on Kintetsu, desiring to take the rights to his iron body, Kaito is approached by Sennen and brought to his hideout. Sennen warns Kaito that Deborah's suit, Baron the Euro, is a prototype designed to be more powerful than Enter the Gold. Later that night, as the news depicts Kaito's challenge to Deborah in a negative light, Isshin and Kintetsu pay him a visit to give their support. As the battle begins the next day, Deborah uses a poison ability to drain Kaito's strength, and despite Kaito's best efforts, he is overwhelmed by Deborah and loses the match.
