In 20XX, the world trembled in fear of an unknown threat known as "KAIJIN." Standing against this menace was Mika, the warrior known as Masked United. After narrowly surviving a near-fatal accident, she miraculously gained the power to control bioelectric currents at will, along with the ability to transform into Masked United. However, this power came at a price. After each battle, overwhelming urges would surge uncontrollably through Mika's body. Overusing her abilities during combat intensified these desires, leaving her vulnerable to enemy manipulation. Just when she thought she had defeated her foe, a new threat emerged—Vaglants, a high-ranking KAIJIN officer. Exposed to his aura, wild impulses raged inside United, causing her to writhe in agony, her body no longer her own. As he groped her groin, she lost control and involuntarily pissing herself. Trembling and convulsing, she was forced to stand before Vaglants, who coldly declared, "You're just like us—a mere monster." Captured and tormented by ever-worsening urges, United struggles to regain control. Will she ever be able to stop this spiral of madness? [BAD END]
