All copies of the game will feature the out of work ninja on both sides of the cover art.
Atlus announced early this week that the sequel to Izuna: The Unemployed Ninja will feature reversible covert art. The backside of the cover art for Izuna 2: The Unemployed Ninja Returns will depict "a beautifully-rendered bust-up portrait" of Izuna. Consumers merely need to slip out the cover slip, turn it over, and re-insert it into their DS game cases to be greeted with the following visage of their favorite itinerant ninja.

Izuna 2: The Unemployed Ninja Returns will be available at American retailers on July 22.
Check Out Izuna's Backside: Izuna 2: The Unemployed Ninja Returns To Feature Reversible Cover Art
June 17, 2008 - Atlus today announced that every copy of Izuna 2: The Unemployed Ninja Returns for Nintendo DS™ will include reverse box art, with the alternate side featuring a beautifully-rendered bust-up portrait of the lovely out-of-work ninja herself.
Izuna and her gang are back—and just in time for a wedding! Lured by the promise of free food (Why else would Izuna attend?), the festive event becomes a puzzling mystery when Izuna's sidekick Shino suddenly disappears, off in search for her long-lost sister. And making matters worse, the foreign gods have also arrived on Japanese soil, and they aren't very happy with the meddlesome, unemployed ninja. With disgruntled deities on the warpath, a sidekick to track down, and a missing sister out in the wild, it could all shape up to be one of Izuna's more exciting adventures. Sounds like a lot of work for a girl out of a job!
