Guides I Am Setsuna WALKTHROUG description

As you begin the game, you find yourself in a forest and meet up with an old masked man, who introduces himself as a mercenary named Hapsper. He'll be working with you on this mission, as you're a mercenary yourself. You're free to rename your character if you please, but his default name of Endir will be used throughout this guide. Talking to the old man will bring up a dialogue option, but these aren't really used for anything, so pick whichever one you want.

Hapsper mentions that you'll be doing all of the fighting on this mission, as he'll simply be an adviser. Once you can move, follow the path a little bit to encounter your first enemy, where you'll learn about the Encounter system here. Basically, if you sneak up behind an enemy without it noticing you, then you'll begin the battle with full ATB and SP gauges. ATB, or Active Time Battle, is a gauge at the bottom of the screen that fills up as battles progress and once it's full, you will be able to select an action.
