The sole female member of Mach Ranger, Mach Pink's Mana Satsuragi, brings the evil organization Death Rain to ruin, ushering in a temporary peace across the world. Her battles have since dwindled to simple missions—mopping up the remaining stragglers. But this peace doesn't last long. A secretly developed physical enhancement system gives rise to a new, supremely powerful warrior. Driven by vengeance for his comrades once defeated by Mach Pink, he launches a new assault. His strength is overwhelming—Mach Pink's techniques become completely ineffective. His tactics not only torment her body but inflict deep psychological wounds as well. Worse, his sexual desire is abnormally intense, and Mach Pink is mercilessly overwhelmed by his relentless lust, ravaged beyond control. Her eyes roll back repeatedly as she suffers defeat after defeat, collapsing into unconsciousness again and again, ultimately led toward the worst possible fate…! [BAD END]
