Unexpected magical disasters that are known as "Magic Calamity" still happened in the world continuously.
In the government, the department that is responsible for countermeasures against the disasters was in disarray due to the loss of some members and its dysfunctional state. There, some members ranging from extremely smart engineers to bureaucrats formed a secret organization "Enigma" in secrecy. The members of Enigma are those who believe that magic is what is breaking the world. Knowing how powerful magic is, they planned to gather all the magic power and use it to fulfill their ambition of ruling the world.
To achieve their ambition, they first must uncover, steal, and make the main culprit who had brought the magic power into the world in the first place, the Mahou Senshi (Magical Warriors) to give up their power voluntarily.
Among the Mahou Senshi, there is one person that they were eying on in particular. Her name is "Ayahime Kurumi", also known as "Lemmtear Theta". Among the Mahou Senshi, she is known as the strongest and has the most powerful magic power. Usually, she works in a magic medical department, but when an incident occurs, she would transform and join force with other Mahou Senshi. Enigma found that when Kurumi engages in battle or when she experiences sexual pleasure, her magic power will be amplified greatly. To maximize her magic power, Engima deployed an "active unit" to attack her. This unit were irrelevant mobs that had received magic power from the rapid spread of magic and wanted to use the power to fulfill their desire.
Then, Lemmtear Theta got attacked and her body which had become highly sensitive from experiencing humiliation countless times began to give in to pleasure. There, a mysterious young girl appeared and rescued Lemmtear Theta. Her name is "Lemmtear Iota" and she is a new member of Mahou Senshi dispatched from the Goddess Imperial Guard Troop in Roa. The new warrior came to this world to prevent and investigate the scheme of Zerou's remnants who had escaped to this world. However, she refused to cooperate with Theta or other Mahou Senshi and began to act alone.
Will Lemmtear Theta and her friends be able prevent Enigma's plan and protect the world once again?
