スタジオジブリ
Level-5 collaborated with Studio Ghibli to produce the game's animated sequences, and the game features graphics and visuals replicating the traditional animation style of Studio Ghibli films. The collaboration began when musician Naoya Fujimaki, who had previously worked with both companies, introduced Level-5 president Akihiro Hino to Studio Ghibli president Toshio Suzuki. At the time, Studio Ghibli had completed work on "Ponyo" (2008), and the animation team had no ongoing projects, which influenced Suzuki's decision to collaborate with Level-5. Another influencing factor of the collaboration was witnessing Hino's passion for the project. Studio Ghibli approached the production process in the same way that they would create an animated film. Work on the animation began in July 2008, and took much longer than the predicted three months.
