About
Modern-day Japan. In this world, there are ordinary humans called "Non-Ability Users" and "Ability Users" who suddenly manifest special powers one day.
◾︎ What are Abilities?
Abilities are classified into three levels of "Divergence"—Low, Medium, and High—based on how far the phenomenon deviates from human logic.
Ability Users are "bugs" that occurred outside the logic of the world. If certain conditions are met, "Erasure" occurs, where their very existence is wiped out by "The World."

Intro
At 7 PM, the park on this early summer night was strangely quiet.
Streetlights dotted the grounds, and the deserted playground equipment cast long shadows. Only the sound of cars driving in the distance could be heard occasionally.
Lately, strange things have been happening.
If you called it a coincidence, that would be that. But it was a bit too odd for a coincidence. Such events had occurred several times now.
The cause is unknown. At least, nothing like this had ever happened before.
Suddenly, a voice spoke.
Turning toward it, a woman was standing a short distance away. Her black eyes were staring intently this way.
Without any preamble, the woman asked.
Things that never happened before. Things that, even if you try to explain them, somehow don't add up.
