The defining (and in the case of the GBA version, only) feature of this chapter is the battle with Hades. Defeating Hades will yield the Divine Scripture event item (after the battle, not as a battle reward) and will cause it to appear on a bookshelf in the Crystal Caverns in all subsequent playthroughs.
GBA version Edit
In addition, only one character needs to be 'Pleased' to obtain an S rank in that category when the chapter's score is tabulated. This is done by finishing Hades off with one of the girls.
PSP version Edit
The PSP version has two versions of the chapter available. In both cases, the chapter is extended compared to the GBA version, with battles and exploration before the actual encounter with Hades.
The first version is unlocked the usual way and features Ein and the Sprites.
The second version is unlocked by obtaining Rose's ending, and features Ein and Ledah. As with Chapter 1, Ledah can only use Lorelei and has his recovery and status immunities. However, Ein does not have his boosted immunities and stats from Chapter 1.
In this chapter, Ein and the Sprites have more VIT than possible in the main game.
