In the drenched capital of Tenshōkyō, fear rules more effectively than law.

The Kurain-humans born with unnatural abilities-are hated, hunted, and blamed for the violence consuming Eios. While politicians promise peace from behind glowing screens, corruption festers beneath the city like a disease.

Seventeen-year-old Riku Hinoki lives between two worlds.

By day, he's a silent student at the elite Hoshin Academy feared and admired by everyone around him. By night, he becomes something far more dangerous-a masked shinobi carrying out covert missions beneath the command of the charismatic political leader Masashido Kurozen, a man determined to "save" society from its own hatred.

But as violence escalates and the line between justice and revenge begins to disappear, one question slowly emerges:

Can a broken world truly be saved...

Or will the people trying to save it become monsters themselves?
