Radiant Historia: Perfect Chronology, an expanded remake of the original game. The character art was redrawn by Masaki Hirooka. The anime opening was created by A-1 Pictures. Hirata's main goals were to update the game so that it would appeal to a modern gaming audience, with these involving increasing gameplay speed and adjusting the user interface. After that he decided to create a new scenario, discussing with staff how to implement it. Haduki, who had worked as the scenario writer on the original release, returned to write the new scenario based on Hirata's original concept. Hirata wanted to restore the original game's two discarded story routes, but instead opted for preserving the established scenario. A new gameplay mechanic was the "Support Skill" system, where characters could perform follow-up attacks.
