The Psychedelic (サイケデリック)1 effect turns Sabitsuki different bright colors when the action button is pressed. It does not give her any abilities or extra powers.
It can be found after navigating the Rave Maze and finding a part of a wall that is different from the rest (see picture below) and touching it then interacting with the NPCs that teleport you across rooftops in the Red Light District.
Once you come in, you need to go to the far right. As right as you can possibly go. If you go up from that, you will see a door. Go through this through another door and you'll be at a clear path. Go right till you see another rainbow door then go through that and follow the picture to find where to click the rainbow strands aside. Interact in the following order: blue, pink, blue, top pink, bottom blue, then bottom blue. You should find the multi-coloured one which will give you the effect.
- Pressing the action button will cause Sabitsuki to change colors. There are a total of 8 different appearances.
- This effect is similar to the Neon effect of Yume Nikki.
