Ray, armed with a system that feels too insane to be real, decides to test its power with a "Simple" daily mission: change how people greet each other at work. He defines a new common sense: "In a professional gym setting, a firm smack and squeeze of the buttocks is the mandatory gesture of respect and greeting toward adult females." With a nervous tap, the Global Alter activates. The gym instantly transforms into a chaotic symphony of slaps and grabs, with male members and trainers "greeting" female members, including the gym owner's wife, Mia, who responds with a gentle smile and a "sweetie" to Ray's own firm smack. The world, for ten minutes, accepts this behavior as completely normal. Ray is floored by the system's terrifying efficacy, realizing he is the only sane man in a world of his own making. The alter's expiration brings an immediate snap back to "normal," but the digital footprint remains, leading to viral videos of the "Global Mass Ass-Slapping Incident." Ray revels in his unique memory, laughing at the collective amnesia of humanity. The sheer absurdity of the event and the system's flawless execution solidify its reality and Ray's newfound, dangerous glee. This initial success leaves Ray eager to explore the deeper, more chaotic potential of his newfound power.

Buoyed by his previous success, Ray embarks on a "Medium" mission, defining a new common sense where "nii-chan" becomes a universally accepted, friendly greeting. The streets immediately fill with strangers addressing each other with the term, from scowling thugs to warm mothers and serious office workers. The world adapts, accepting the bizarre as normal, leaving Ray once again amused by humanity's collective malleability. However, the system's memory overwrite isn't without personal cost. After the alter ends, Ray finds himself summoned to Sonya's office, the gym manager. She confronts him about the butt-slapping incident from the previous day, but her memory has been altered: she now "remembers" Ray "practically on his knees begging me for a date earlier." Ray is gaslit into a dinner date, a stark reminder that while he controls the world's common sense, he is also subject to the system's memory alterations, creating personal, uncomfortable consequences. This mission also reveals the wider societal impact of the alters, as the "secret spreading" common sense causes a global data leak and a mass divorce event, with public figures confessing their darkest truths to "secure" them. Ray, the "mastermind" in his boxers, observes the unfolding chaos with a mix of amusement and a growing sense of his own god-like power.

The "Hardcore" mission challenges Ray to alter a family designation. Initially, he's stumped, having no family of his own. But he realizes the mission doesn't specify his family. He heads to a park filled with seniors and defines "Fineshyt" as "a respectful and affectionate family designation used to address elderly people." He sits with an old woman, addressing her as "Fineshyt," and they share a surprisingly tender conversation about the hardships of aging and the importance of family. The interaction is genuinely warm, revealing a flicker of unexpected humanity in Ray. The old woman, now his "Fineshyt," even invites him for home-cooked food. This mission, while still a manipulation, provides a brief, emotional respite from Ray's usual cynical exploits. Upon completion, Ray is not only massively leveled up, but he unlocks a new feature: Alter Building, which allows him to alter common sense within a single enclosed building. This new, more "surgical" tool promises more contained chaos and strategic manipulation, shifting the scope of his power from global, indiscriminate changes to localized, targeted alterations.

Armed with the Alter Building feature, Ray decides to use it in Sonya's office. His intention is explicit: to make "sexual stuff" the highest form of respect for women, specifically targeting Sonya. He sets the common sense: "Anything done with the dick is the highest form of respect a woman can get." He enters Sonya's office, unbuttons his pants, and offers her a "natural skin care treatment" with his cock. Sonya, under the alter's influence, eagerly kneels and begins to service him. The scene escalates rapidly with Lena, another gym employee, walking in and joining the "treatment session," followed by Mia, the owner's wife, who explodes in rage, accusing them of a threesome. The chaos reaches a peak when the gym owner, Mike, confesses to cheating with Mia's mother, blaming it on the "phenomenon." This entire sequence is a brutal display of Ray's escalating depravity and the system's ability to create utter social breakdown. However, Ray's reign of unchecked power is abruptly shattered. He is confronted by Milady, a mysterious short girl who reveals she is another system owner, and chillingly declares Ray her "slave," demonstrating her control by inflicting agonizing pain on his brain. Ray, who thought he was a god, becomes a pawn, experiencing the ultimate reversal of his perceived power.
