A pair of happy twin girls shared a same dream on their sixteenth birthday. The next morning, they felt empowered with a strange energy. The following night, they both had a nightmare and fell into a state of unconsciousness. Their souls were transported to an unknown dimension. When they awoke, they noticed they were wearing strange costumes on their bodies and regained their power of transformation they had lost in a previous life. The two realized that they had to combine their forces in order to return to their own world. Reluctantly, they advanced into the dark where the evil souls happily engulfed them. [ Background Source ]
