The darkness that hid for so long must come out, and this time no one is safe.

In the night of Okutama Forest, the survivors hear strange sounds moving around them: ticking... metal scraping... and a silence more dangerous than the noise. Then shadows begin to appear from every direction, and Son and his friends, together with Misaki and Rin, must decide in a single moment: run, or fight?

Behind the fence, a dark facility waits for them, and what they find inside may change everything.

📖 What's inside:

• of action, horror and suspense

• Sounds in the night and shadows you can't count

• Sword and spear battles in the dark

• An ending that opens a new door
