Yusuke Nogi from Ryosho's Energy Development Division reported that 10 times the official down payment was mistakenly sent to GFL, a local infrastructure company involved in a solar energy plant to be constructed in the Balkan Republic in Central Asia. Suspected of involvement, he travels to the Balkan Republic to recover the $90 million difference. With the help of his CIA friend Sam, Nogi learned that the terrorist al-Zaer had laundered the entire contract amount into diamonds and smuggled them out.
