From the XSEED Press Release:
Originally released in Japan as Zwei II Plus and developed by acclaimed RPG developer Nihon Falcom, Zwei: The Ilvard Insurrection is a charmingly presented action RPG featuring a unique food-based experience system, a colorful cast of characters, and a quirky, standalone narrative. When the haughty vampire princess Alwen du Moonbria saves the life of brash, treasure-hunting pilot Ragna Valentine in exchange for a blood contract, the unlikely duo must set off to recover Alwen’s stolen magic and usurped castle.
The game’s real-time combat is tied to a unique leveling system that allows players to choose when to apply experience toward leveling up or whether they should save it for extra perks later on, and pets can fight alongside players to help take down some of the massive bosses encountered on this lengthy adventure through the land of Ilvard. Fans of vampires, treasure-hunting, fairies, ninjas, luchadores, cat-people, vintage airplanes, magic castles, robots, chickens that lay bombs, and more will find lots to love! ©Nihon Falcom Corporation.

As an additional note: Falcom originally released Zwei II in 2009. This wonderful action RPG is infamously their final PC platform title, and has yet to see a console port for it. In 2009, Falcom lost their PC distribution due to declining sales. As a result, the English release of the game that Falcom clearly loved is a much needed chance at redemption from English speaking audiences.
