In "Pandora in the Crimson Shell," Nene Nanakorobi, an energetic full-body cyborg who desires global peace, meets inventor Uzal Delilah aboard a cruise ship heading toward the tranquil Cenancle Island. They quickly become friends with Clarion, a feline combat android who accompanies Uzal. Their bond is tested when terrorists attack the island. To protect Uzal, Nene receives the Pandora Device, originally housed inside Clarion, granting her the ability to instantly master complex skills, though Uzal appears to die in the incident. The pair then carry out various missions, such as rescuing children from burning malls and apprehending criminals, all in pursuit of world peace. Their efforts are further complicated by B.U.E.R., a sentient laser disguised as a deformed teddy bear with unpredictable power and crude behavior, posing a constant danger. Adding to their troubles, Takumi Korobase, Nene’s guardian and a genius inventor, becomes obsessed with obtaining B.U.E.R. As Nene and Clarion strive to protect the Pandora Device from enemies and uphold their idealistic goals, the mounting pressure threatens to break their newly formed partnership.
