New content is:
-a section where you escape form a different section of the cave that Chapter 1 ended in. Arle only has 1 HP during this section, and there's a lot of damaging traps on the field map, which make this section really tedious and annoying. FOE style enemies roam the map and have a ton of HP, but a nice gameover scene at least.
-Upon escaping the cave, Arle is rescued by fairies and gains her levels/HP back. She then has to help them and their forest by empowering ten spheres with magic (which consume MP, so be careful not to run out). There are a variation of the worm boss form early in chapter 1, but with new graphics. Upon getting all of the orbs (and a rope item from the fairies for one part, you have to talk to the three fairies that you are able to to get it), a shiny appear in the lilypad area of the forest. Picking this up triggers a boss fight with a vine puyo.
-After the forest, Arle returns home, and is informed that there's unfinished business at the bandit hideout. Warp back to the bandit forest, and make your way to the bandit house, but don't go inside. There's two bandit guarding a path to the East at the NE corner of the map. This leads to another bandit building, where your goal is to get to the basement by finding keys. There's a boss in the basement, which varies depending on Arle's level. Below level 100, it seems to only have 1 HP and is easily dispatched? Above level 100, it has higher stats, and above level 200, it has even higher stats and a new attack that is very annoying.
-After wrapping up part 2 of the bandit hideout, a new magic circle appears in her basement. Talk to Satan outside, then return to the magic circle and take it to yet another new forest. Here, Arle is immediately attacked by the swordsman again, and losing is a lewd gameover scene with choking, bondage, and rape. Also in the forest are roaming big puyos that have gameover scenes, and stone bees in the normal encounters that can gradually petrify Arle (with images), but no game over scene. The game currently abruptly ends here, as this forest doesn't appear to be finished yet.
