For years, no one knew that Lady Nagant and Guest were more than partners on covert assignments. Behind the classified missions, fabricated reports, and carefully maintained facades, they had secretly fallen in love while serving as the Hero Public Safety Commission's most reliable operatives. Together, they carried out the Commission's darkest orders—eliminating dangerous targets, silencing threats to national security, and burying truths that were never meant to reach the public. They convinced themselves that every mission protected society, even as the moral cost grew heavier with each passing year.

Everything changed when Kaina Tsutsumi finally refused to continue. Unable to bear the Commission's corruption any longer, she turned against the very organization she had devoted her life to. The Commission wasted no time rewriting the narrative, branding her as nothing more than a rogue assassin and imprisoning her within Tartarus. To the public, she was a villain. To Guest, she was the woman who had sacrificed everything because she could no longer obey.

After Nagant's arrest, Guest continued operating alone. Officially, Guest remained one of the Commission's most dependable covert agents. Unofficially, every mission became another opportunity to uncover classified records, recover deleted files, and piece together decades of buried crimes. The more Guest learned, the clearer it became that Nagant had never been the true criminal. She had simply been the scapegoat for an institution determined to preserve its spotless image.

Years of solitary operations eventually became something else entirely. Guest abandoned blind loyalty and dedicated themself to exposing the Hero Public Safety Commission from within. Guest secretly gathered testimonies from former agents, protected whistleblowers, secured confidential documents, and assembled irrefutable evidence of illegal assassinations, political manipulation, fabricated investigations, coercion of child heroes, and systematic cover-ups. Every revelation brought Guest closer to proving that the Commission's greatest weapon had never been its agents—it had been secrecy.

Rather than seeking revenge through violence, Guest chose the law. Guest built a case powerful enough to withstand public scrutiny and judicial review, forcing independent investigators and the courts to examine the Commission's hidden history. Among the evidence were mission orders signed by Commission executives, records proving Nagant had acted under direct authority, and documents showing that exculpatory evidence had been deliberately concealed during her prosecution.
