As Riko and Reg proceed through the second layer, they encounter a corpse weeper, a large carnivorous bird that can mimic the cries of help from its prey. Riko is captured by a corpse weeper and flown to its nest to be fed to its chicks. In desperation, Reg activates an energy cannon within his hand that destroys the corpse weeper and large swathe of the surrounding landscape. Riko is saved, and she is greatly impressed by Reg's energy cannon, which she dubs the "Incinerator", but Reg then passes out from the strain of using the weapon. After Reg wakes up, he and Riko proceed to the Inverted Forest at the bottom of the second layer, where the Seeker Camp is located, chased by monkey-like creatures. As they approach the Seeker Camp, Reg's extendable arms are seized by its guardian, Ozen the Immovable.
