"The Iron Mask Incident I" Volume I: Complete Record of Attacks
1.1 First Attack: Sewer Assault

Scene: The bodies of two Asterleeds Defense Corps soldiers were discovered in the sewer. The fatal injuries were deep neck punctures. The bodies were arranged in a kneeling posture, facing the direction of the Corps headquarters. The weapon used was a standard-issue Defense Corps firearm (Serial No. Gun-1079, originally assigned to the deceased soldier, Ryan Clough).
Internal Corps Report: "Preliminary assessment indicates a retaliatory strike by the violent group 'The Hobos'. It is recommended to suppress the news to prevent public panic. "

1.2 Second Incident: Arena Town Theater Assault

Witness Testimony (excerpt from Thomas' notes, a reporter at Ocean Hill Evening News): "During the third act of 'The Nobles of Byrnhald', the protagonist's wings suddenly ejected shards of gears. Defense Corps soldier Thomas, seated nearby, was struck and seriously injured.
Upon investigating the control panel, a modified firearm was found lodged in it, with the handle inscribed 'Legacy Knight No. 1'. "

Technical Analysis (from Artisan Guild's report): "The weapon was a modified training firearm issued to the Defense Corps. The training module appears to have been replaced with a high-damage combat module."

1.3 Final Showdown: The Bell Tower Duel
Testimony from Surviving Defense Corps Soldier (Audio Recording No. 102, name omitted for safety reasons): "It was a man wearing an iron mask, his right arm moving too swiftly to be human... Soldier Adeline fought him, and in the end, she used Ryan's old sidearm to shoot through Ryan's chest. That's when Ryan finally fell.
But at that moment... I heard Ryan's body make the sound of metal being pierced. "

Autopsy Report: "The killer's right body had been modified with an unknown module, and a metal plate had been attached to his face. The left side of his face matched that of Ryan Clough. Ryan's heart was absent from the body." --- "The Iron Mask Incident II" Volume II: The Altered History

Dr. ■■'s Mentor, Master Artisan Mason Stonecutter: "Ryan's tragedy is a clear reminder-when technology eclipses humanity, the abuse of Legacy will ultimately consume the soul. "
