The diagonal paths' connection
Angel, Devil, Heart
The Cyber Maze (サイバーの通路, Saibā no tsūro, Cyber Passage) is a small area accessible from various zones, the quickest way being Valentine Land by interacting with the walking heart.
This area is an 8-directional looping hub. Each path has a particular color and takes you to a path of another color and, sometimes, has an NPC that can be interacted with to go to another zone.
If you take the pink path, you will find the walking heart mentioned before, taking you to Valentine Land. This path connects to the purple path, which will make you find a bat-looking Devil. Interacting with it will take you to the Exhibition.
The red path doesn't have any NPCs to interact with, but it connects to the blue path, where the Angel taking you to GALAXY Town can be found.
The yellow path connects to the green path, and the two multi-colored paths are connected to each other. All 4 paths don't have any NPCs to interact with.
