Naka was arrested alongside Square Enix employee Taisuke Sazaki for allegedly having confidential knowledge of Final Fantasy 7: The First Soldier's existence before the game was announced. Using that knowledge, Naka reportedly bought roughly 120,000 shares in the game's developer ATeam before its public reveal. These shares were worth around 144.7 million yen (that's $1 million), thus making for a pretty damning case of insider trading. This amount far exceeds that which was reported in Naka's original arrest for insider trading over Dragon Quest Tact. In a similar turn of events, Naka allegedly purchased 10,000 shares in the developer's studio Aiming for 2.8 million yen (around $20,000) before the game was revealed. Square Enix employee Taisuke Sazaki was involved in this charge too. Over the new Final Fantasy charges, Naka, Sazaki and an unnamed third party allegedly participated in insider trading together.
