The silver wings responsible for the rise of Nega Nebulus, the legion led by Kuroyukihime, are weakening! During the battle with the mysterious Acceleration Research Society, Haruyuki sustained corrosion damage from the revived Chrome Disaster, and he has still been unable to escape its effects.

Now Haruyuki is faced with a choice--undergo the grueling purification process, or have a bounty on his head and risk being cast out of the Accelerated World altogether!
