The year is 2084 AD. Magic users known as Justices have existed since the dawn of written history. However, many distrust Justices and see them as an aberration of the human race. Designated as Anti-Magic Faction groups, these xenophobic militants of humanity have spread worldwide to eradicate Justices and those who support them.

Aya Masayoshi is a middle school student on Arahi, an island encroached by AMF influence, as crime and corruption run the country. Her life changes upon meeting a young girl on the run from the authorities while releasing an alien threat as old as the Justices themselves. Now a Justice herself, Aya rises to the challenges ahead of her, whether it be overcoming her issues at school and home, confronting this ancient menace, or triggering a revolution to end the tyrannical world order for good.
