Remi Takashima is a four year girl. The building which Remi lived in had burned down. After going through the remains, firefighters found her buried under some rubble, and amazingly, she was still breathing. Assuming Remi possessed the beast gene, she was kept alive to be used as a guinea pig.      ~!After being observed in the hospital, she once again unintentionally starts a fire. Jun is sent in to eliminate Remi. After being attacked by her fire, Jun transforms, but still tries to confront Remi without hurting her. We see a flashback, and learn that, after finding an interest in fire, Remi found that she had the power to start fires with her mind. Remi unintentionally started a fire in her room. Her mother came in to her room to get her, but after touching Remi&#039;s hand, she caught on fire and burned to death.     Remi calls for her mother, and walks toward Jun, arms open. Jun hugs Remi, and the fire surrounding the child slowly dies out. Jun hugs Remi one last time, and the child cracks and falls apart. All of this having started because Remi possessed the Beast gene, and was unable to control her powers.!~

Fudo Jun is a beautiful supermodel who is idolized by many. She also has a dark secret that not even she knows about at first, for within her veins run the genes that hold the next step in the evolution of mankind. The same blood as the beastlike superhumans that terrorize the city. Unlike the rest of them, though, Jun has managed to hold a tenuous grip onto her humanity, and she is recruited by the mysterious Asuka Ran, member of a secret organization within the government, aimed at controlling, if not eliminating, these berserk destroyers of mankind. Jun, as Devilman Lady, must now exterminate her own kind, but how much longer can she keep her sanity in a situation she never chose in the first place?
