In a world where demons steal human souls to fuel their wicked desires, the Demon King, their ruler, uses a school as his base while preparing to plunge deeper into darkness. Meanwhile, Dynawoman, a super agent sworn to protect the world's peace, infiltrates the school disguised as a female teacher to uncover the Demon King's whereabouts. One afternoon during remedial class, demons suddenly attack in front of the students. Cornered and desperate, Dynawoman instantly transforms, fighting back with beauty and strength. However, Majora, a high-ranking female commander who has become a priestess of the demon realm, traps her using a venomous demon spider from the underworld. Paralyzed and unable to move, Dynawoman is mercilessly stimulated between her legs as Majora targets her most sensitive spots. Forced into climax, she experiences a powerful female ejaculation, gushing fluid uncontrollably. Before she can process the shame or humiliation, she loses consciousness and is delivered to the Demon King. His rigorously trained body ruthlessly conquers hers, making her climax repeatedly in degrading positions. She barely escapes, but the sensation lingers within her, vowing revenge—only to be conquered once again. This time, Dynawoman's hands unconsciously pull the Demon King closer in a tight embrace. It was the undeniable sign of loyalty born from her complete corruption. [BAD END]
