When characters pass into the Netherworld, the gameplay shifts entirely towards the action-adventure side of its genre. Basic attack techniques are performed by utilizing "folk", various creatures and spirits that upon defeat can be absorbed for the player's use. When a folk is nearly defeated, its spirit will glow red, allowing players to absorb it by locking onto it and performing shaking and yanking motions with the Sixaxis motion control (rather than a conventional button interface) to reel in its energy for use. While the player can choose from nearly all folk encountered and absorbed, only four at a time can be mapped to the controller's main four interface/action buttons and used in quick succession for combat with different kinds of folk being better suited for certain situations and techniques such as close-combat, projectile attacks or magic. The two playable characters themselves also differ between play styles. While Ellen uses a variety of folk as basic strategy and favors a defensive stance with the ability to cloak herself with folk powers, Keats uses more straight up brute force attacks with usually all-round stronger folk along with the ability to release built-up energy to become invincible and perform stronger attacks for a period of time.
