Block World

Going east from the Nexus door and then north when you see a yellow cube with a hole in the middle above Toritsuki will be a odd pillar which will take you to the White Maze, going south of the door to the Nexus is a door that leads to the cube item. There is a dark green building with a Chaser NPC where you can change your menu color, with 3 colors available.
