|Green Neon World|
This area closely resembles Neon World in Yume Nikki and .flow, containing fluorescent blue cubes and strange green and yellow objects. Sometimes light pulses or waves are emitted from beneath Urotsuki. This event occurs randomly but is sometimes triggered when stepping behind blocks.
By traveling north-east from the entrance, you will find a small cube that takes you to the Construction Frame Building.
Stepping in the back of a blue cube (not constituting a mass) south from the small cube portal will lead you to a fancy room with a blue creature. Urotsuki will shake her head if you try to walk further into the room. When you use Glasses effect in this room, you can see what appears to be a broken rotten egg. This act is key to Ending 06. This hidden room is similar to each one of Rough Ash World and Flying Fish World.
