Ultimania is the authoritative guide to Chrono Cross in Japan, released by DigiCube, who handled Squaresoft's merchandise. It features boundless information, interviews with the team, and even some plot analysis. However, some of this analysis conflicts with Masato Kato's own words or the game; for this reason, Ultimania cannot be completely trusted as a canon source.
