Using feedback from the original game, the team decreased and smoothed the transition between exploration and battle, and adjusted the controls to be more user-friendly. The character of Aya had been created for Parasite Eve by the producer Hironobu Sakaguchi, and designed by artist Tetsuya Nomura. Her design in Parasite Eve II was handled by a different artist, using her original design as a template. While most of the design was finalized, the new designer had quit halfway through the game's development, and Nomura was called in again. As the in-game model had already been created, he preserved what had already been done while adding touches of his own. After the game was done, the team was merged with those behind Brave Fencer Musashi, Mana and Chrono Cross to make Final Fantasy XI.

The game's music is depicted as being much more ambient than its predecessor. The sound effects of Parasite Eve II were influenced by futuristic and sci-fi themes.
