2236 A.D. [Sekai Project & Chloro]

This tale began five years earlier, in the spring of 2231. Mankind has evolved a new kind of communication ability called “telepathy.” Yotsuba notices a young girl who does not use telepathy in his first term. In the days that follow, she remains closed off.

One day in the yard at his home, Yotsuba finds a Phillips-head screwdriver. He traces its origin to a nearby abandoned manor, and enters. Inside, he finds something…

The thing that humanity has denied.
The thing that memory has forgotten.
