After learning from Sennen about the Underbank cyberspace Adachi resides in, Kaito meets up with the Hero Bank company president, Kinzo Sengoku, who explains he is unable to give Kaito his prize because Money Ghost's interference has put his company in trouble. Just then, Adachi puts his plan into action, using Nagare's power to drain everyone's bank accounts and remove money from the world. He then covers the world in cyberspace and unleashes an army of Megalion Ghost Hero Suits to destroy the city. Learning the Megalions are made from data, Kaito and the others are able to use their Hero Suits to fight back, earning battle money from around the world. With more people joining the fight, Kaito heads towards the Underbank to rescue Nagare.
