In ancient times, there existed a mythical beast called the Phantom Beast. This mythical beast is capable of ever-changing forms, and no one has ever seen his true face.
But this mythical beast saved a child who was being hunted. From the moment he rescued the child, he had already fallen in love with the child.
The child never thought that he could see the legendary beast and be liked by it, and unknowingly, he also fell in love with this legendary beast.
