MSZ-12 Heroine Special Punishment: Divine Beast Squadron Beast Ranger, Beast Yellow, Oikawa Umi

The Beast Ranger, a heroic team that fights every day to protect people from the evil organization Ashura Gang. One of its members, Beast Yellow, Rinka Kizaki, battles Ashura Gang’s soldiers alone and barely drives them off. However, a man who has been obsessively following Beast Yellow steals the confidential Beast Suit data card containing Rinka’s secret information. He brings it to Ashura Gang and, in order to make Beast Yellow his own, asks to be turned into a monster himself.

A few days later, a chimera monster appears before Beast Yellow. Exploiting a weakness in the female enhanced suits of the Beast Ranger, which can intensify sensual stimulation, the monster defeats her with an attack that overwhelms her senses. Beast Yellow is then abducted to Ashura Gang’s hideout, where the chimera monster subjects her to relentless psychological pressure and attempts to break her resolve. As the repeated waves of pleasure push both mind and body to their limits, she is driven into a corner, her expression caught between anguish and dazed surrender.

In the end, Beast Yellow gives in to the overwhelming sensations. She comes to seek pleasure on her own, sinking into it with an empty, submissive expression. [BAD END]
