This is the entire Final Fantasy VIII game written from Rinoa's point of view. Diaries and details were filled in by FF8 Ultimania or FF8 Memorial Album and then paraphrased. The following pages contain spoilers and are best read after you have finished playing.
It should be noted that Rinoa is highly out of character in her diary entries. Whether she is talking to herself or someone else isn't quite clear. The entries were written by Benny Matsuyama, who works on guidebooks for Squaresoft games.
