A nightmare that Shingo is having one night becomes the preamble to having it explained that Governor Tachibana has discovered a below-ground catacomb of tunnels that are reputed to house vast treasure that could greatly boost anybody's micro-economy. Shingo reads this as an opportunity to boost Parthenon Productions's economic fortunes with a TV special; while Shingo and Governor Tachibana agonize over when the actual excavation will begin before having it explained that there is a family curse associated with the estate, Mamoru gleams with the excitement of the hunt as he races off with Yuu right on his heels along with Toshio and Midori. Shingo and Governor Tachibana now caught with their pants down with the newly-arrived television crew frightened that they will have the treasure stolen from them, the excavation begins in earnest along with the filming to reveal a tunnel into which Mamoru eagerly leads the way deftly defeating the traps he encounters. The ultimate irony of the whole spelunking adventure is that there is neither treasure nor family curse; the closest thing to a curse is the 2.25 mega-yen lesson to want what you already have that Shingo is not refined enough to master.
