control of another new character, Squares. The cast of characters travel aboard the S.S Tetra to ask for Ex's guidance, who creates a path of various riddles to help Marle recall the circumstances surrounding the merging of worlds and Squares. After regaining her memories, Marle explains that she is the human incarnation of the Will of the Worlds, and that Squares was created by her to focus on maintaining the order of the world. The group of friends travel to the edge of the two worlds and face off against Squares, who wishes to destroy both worlds entirely due to their merging disrupting the natural order. As they battle Squares, Marle comes to the realization that Squares has the mentality of an infant despite his older appearance and voice. Marle calms Squares, and the group help quell the power he had progressively gained over the course of the adventure. After saying their sentimental goodbyes, the worlds separate once more.
