Izuna 2: The Unemployed Ninja Returns featured some fairly risque alternate boxart in Japan, where initial shipments were packaged in H-game-like boxes with art of Izuna and Shino bathing in an onsen. The American box for the game may not be modeled after erogames, but it does feature some extra pinup-style art of the title character.
In an absolutely lovely trend, the Izuna 2 boxart has been revealed as reversible, like the boxart for Victorious Boxers Revolution. However, instead of alternate boxart on the other side, the reverse of Izuna 2's cover is a mini-poster of the title character. Nice to see Atlus treating a niche game like Izuna as such a deluxe product.
