After winning a lottery in the shopping center, Kaito, Mitsuo, Fukuta, Ai, and Kaito's grandfather Zōan head to a hot spring inn, where Hana and the Gamitsui Corporation are coincidentally helping out. Later that night, Kaito accidentally breaks his Bankfon G after being spooked by Ai . Afterwards, Kaito runs into Hana, who explains she is trying to help out the inn, which holds a lot of memories for her, to keep it from being sold to a developer, before accidentally spraining her ankle. The next day, the developer, Ageo Sokoo, comes and smashes the inn's entranceway, trying to coerce the owner into selling the inn . Wanting to protect Hana's memories, Kaito challenges Sokoo to a Hero Battle against his Hero Suit, Heavy Builder, with the inn on the line.
