Mayura Tenjikudō stands as one of the twin schoolgirl protagonists, distinguished by her blue hair against her sister Sarasa's red. Her personality diverges sharply from her twin, marked by sexual experience and an active pursuit of physical relationships. She exhibits scientific aptitude in her role as a researcher.

Their scientist mother designed specialized power suits that enable superhero transformations. These suits resemble oversized animal costumes, requiring manual entry after their clothing vanishes during activation—a process Mayura finds logically baffling. The twins deploy these suits against invading forces commanded by the inept villain Kyomoto, who seeks their mother’s aid for world conquest.

A core combat mechanic demands synchronized orgasms between the sisters to generate necessary power, devoid of incestuous interaction. During missions, Mayura endures molestation by a female antagonist. Her scientific expertise aids strategic counterattacks against adversaries like a gear-based monster and a thread-launching sewing machine creature.

In personal subplots, she initiates a sexual encounter with her teacher, framed within the series’ contextual norms. She collaborates with Sarasa to pilot a gynoid mecha during critical confrontations.
