Ai is an elementary school student in 1990s Japan, who will soon realize how isolated she is.

Forced to play children's games in a world of endless twilight, Ai is hunted by alien entities as her life hangs by a thread.

When these horrific situations begin to leak into the real world, Ai must accept that she has only three choices: hide, run, or disappear.

• Evolving Gameplay: Test your strengths in a dangerous game of hide and seek before embarking on a terrifyingly twisted version of "tag" with abyssal apparitions.
• Use the items you've collected to escape your sunset, but make sure you remember the paths you took or risk being trapped there forever.
• Japanese locations burn with a hauntingly beautiful sunset: Experience a chilling blend of beauty, horror, and nostalgia in a mysterious world where a Japanese house, school, and hospital are interconnected.
• Explore corridors painted red twilight, observe the ghostly glow of amber through the paper walls of a traditional Japanese house, and escape from threatening black shadows in hospital rooms where the electricity is always off.
• Ai, 10 years old, has no defensive measures to defeat the enemies she faces. Instead, you must exploit each spirit's weaknesses to survive.
• Hold your breath to hide from blind enemies or run quickly from the deaf as fast as you can.
• If you fail to escape in time, prepare to suffer a terrifying fate at the hands of unimaginable forces.
• A tragic story of friendship, betrayal, and confronting your own struggles.
• After completing the game, another ending will be available.
