It's all in the archive (save for parts of one that was begun on a different forum). The games in the Purvis chronology are Patchouli, Reisen, Utsuho, Maribel, Iku, Nue, Kisume, Yukari, and Miko/Youmu, with (most of) Ran thrown in as a side game that provides a little bit of backstory to how the Buddhists showed up and why Aya began everything in jail.
