Waking up in the middle of an orientation ceremony, Jace Monroe discovers he has transmigrated into a soft, overweight body with a ticking seventy-two-hour lifespan. The shock of his new reality is compounded by the arrival of the Divine Milking System, a highly degenerate system that demands he extract magical essence from women to survive. Surrounded by arrogant guild heirs who look down on lottery admissions, Jace immediately begins scanning his environment for potential targets. He activates Snake Eyes, a passive ability that overlays the bust sizes and attraction levels of every female student in his field of view. He zeroes in on Belle Fox, a materialistic first-year in House Obsidian who possesses a transactional survival instinct. During their first dinner, Jace uses his modern wit and the charm effect of his system to break through her icy exterior, establishing a tentative rapport while other students watch in disbelief. He also meets his roommate, Hikaru Tanaka, a cold and intensely disciplined student who Jace secretly knows is a crossdressing girl fleeing an arranged marriage in Japan. Balancing the threat of his roommate's lethal abilities and his own physical weakness, Jace pushes through his first grueling day of physical conditioning under Coach Garrett, logging minor stat increases but knowing he is still running out of time. With his death timer rapidly counting down, Jace makes a bold move and invites the wholesome, pink-haired Naomi Love to a private evening training session on the East Field, setting the stage for a desperate gamble that will either save his life or ruin his standing at the academy. As the sun sets over the ocean, Naomi arrives in athletic wear, completely unaware that Jace is about to reveal his most closely guarded secrets in a pocket dimension where the rules of the academy no longer apply. He must convince her to trust him completely within minutes, or face absolute deletion when the timer hits zero.

On the isolated East Field, Jace initiates his plan by helping Naomi train her Wave Motion ability, which converts her physical stamina into devastating energy projectiles. Under the guise of training his own support ability, Jace uses Euphoric Feedback to transmit pleasurable sensations directly into her nervous system, gradually escalating the intensity from a gentle warmth to overwhelming ecstasy. As her attraction level surges to fifty percent, Jace takes a massive risk and activates Private Sanctum, pulling her into a luxurious, fully customized pocket dimension. In this private space, Jace lays bare the reality of his situation, showing her his glowing blue death timer and explaining that he will die unless he extracts her magical essence. Overcoming her initial shock and anger, Naomi's deep empathy wins out, and she agrees to save his life. The ensuing extraction session is a sensory overload of physical intimacy and magical transfer, during which Jace drinks her Silver-tier milk, extending his lifespan to a comfortable seven days and accumulating over five hundred system points. Through the system's Ability Theft mechanic, Jace successfully steals Naomi's Wave Motion ability, unlocking the potential for high-intensity ranged attacks and flight. This pivotal victory transforms Jace from a helpless victim of fate into an active player with a formidable combat option and a secure lease on life. However, the physical toll of the extraction leaves Naomi visibly exhausted the next morning, raising suspicion among their teammates and forcing Jace to manage the delicate emotional fallout of their secret arrangement. When they return to the real world, Jace must face his roommate Hikaru, who is already highly suspicious of his late-night absences and sudden bursts of unearned confidence, leaving him with little room for error as the academy's competitive pressure mounts. He realizes that maintaining this double life will require absolute precision, especially as the first official team evaluations loom closer.

With his immediate survival secured, Jace must integrate into the academy's rigorous academic and physical curriculum. During homeroom, instructor Dominic Vale announces the creation of five-student squads for the upcoming evaluations, forcing Jace into a team with Belle Fox, Naomi Love, the lazy yet observant Jordan Wayne, and the athletic, lime-haired Misato Ayame. Officially named the Midnight Foxes, the squad represents a volatile mix of low-status lottery admissions and high-potential support types. Misato, who also acts as their self-appointed drill sergeant, immediately subjects the team to a brutal training regimen on the field. She singles out Jace, pushing his unconditioned body through a series of exhausting physical drills designed to test his limits. Jace uses this opportunity to further test his system's capabilities, demonstrating a modified version of his support touch on Misato herself to temporarily alleviate her muscle fatigue.
