Round 2! Adults Have Their Own Big Problems!! (E17)

Long, who was accepted as Big Money Company's Vice President, was actually a spy sent by the Money Ghost. Kaito heads into round two of the Hero Wars none the wiser. His opponent is so dull he believes he will win an overwhelming victory and uses Explosive Gold Rush right off the bat. However, an unforeseen "bug" occurs, and he might be in big trouble!
