Set in Kyoto 2024, the Japanese government has made plans to collect and preserve the city's natural architecture and culture through drones in real time, storing all its data in an infinite-capacity quantum computer known as Alltale.
Returning, defeated, to the city, Naomi is suddenly faced with thousands of kitsune men — an effect of Sensei deciding to reboot the system after all data relevant to Ruri's existence has been rewritten.
The system then automatically starts filtering parts of data to keep and those to be erased, causing the space within 2024 Kyoto to shift and for red auroras to appear in the sky.
Teenage Naomi warps to Ruri's hospital room and prepares to bring her to the staircase outside Alltale's complex, which has the optimal spatial coordinates for them to return to their original world.
