As dusk settled, Rose was walking through the wasteland outside town. She wouldn't have ventured into such a dangerous area if not for an urgent errand. In a hurry to return home, she heard a faint wheezing sound. She should have ignored it, but she couldn't help but check it out.

Peering behind a rock, she saw a creature she'd never seen before, lying wounded, breathing heavily. Though frightened, Rose felt a strange urge to help the suffering creature. But as soon as the creature locked its eyes on her, it opened its massive jaws wide and tore her body to pieces.

As dawn broke, she opened her eyes behind a rock. I must have dreamt that I was devoured by a terrible monster, not a scratch on my body. She must have been very tired to fall asleep in such a place. Rose left the black stain behind the rock and hurried back to town.

Cursed by an unidentified demon, Rose has unwittingly acquired the demon's powers. She can now separate her body at will and transform it into fangs and jaws. In addition, her overwhelming monstrous strength should remove all obstacles that stand in her way.

Rain is her protégé. Vanilla is her childhood best friend ... and henchman.

Rose had been cursed by the unknown monster, uninentionally gaining its powers. Now, she can freely separate her body parts, and reshape herself into jaws and fangs. Her superhuman strength can crush any obstacle in her path.

Rein is kind of her henchman. Vanilla is her best friend since childhood... and also kind of her henchman.
