Ep. 1: Rohan and Izumi visit Millionaire Village to test strict etiquette rules and mountain gods

1

Kyouka Izumi convinces Rohan to join her at the secluded Millionaire Village for a potential villa purchase, warning him about the residents' strict manners. After rescuing a bird and meeting doorman Ikkyuu, they are accused of violating rules. When Izumi learns of her family's death in a car accident and the bird is found dead, Rohan uses Heaven's Door on Ikkyuu. He learns that mountain gods punish breaches of etiquette by taking precious things away. Rohan's own violation causes Izumi a heart attack, leading to a test involving eating corn on the cob. Rohan realizes the setup, tricks Ikkyuu into breaking his own rules repeatedly, and ultimately saves Izumi and her loved ones from the consequences.
