Mao Hamasaki stars as San Angel, the second of the Span Dekusar triplet superheroines who have arrived from space to protect Earth. Working undercover as a rookie journalist for Independent Journal, she plays a crucial role in safeguarding people from evil forces. Among her key targets is Dr. Fumido Ozu, a genius scientist who has developed the groundbreaking theory of elemental separation beams, drawing the attention of the space pirate group Hidoo. When reporter Rin Mii visits his laboratory for an interview, she senses an ominous atmosphere. Shortly after, Hidoo's bio-weapons launch a surprise attack. San Angel rises to defend the doctor, but soon finds herself facing even more terrifying enemies. What follows is a far more brutal and intense battle than anyone anticipated.
