A/N:Just a Prologue, a short one but this is an understanding of an Anime many of you may not recognize, enjoy.
Some humans have an unusual gift that grants them the ability to morph one or more of their body parts, such as limbs, into a form similar to an animal's body part. Some are capable of even more radical changes, such as growing wings or full-body transformation. The transformation processes are very fast, and occur at the user's will. When inactive, the morphed areas revert back to normal, leaving person's clothing and body completely untouched. The only visual mark of this ability appears on the body of the person, in the form of a black tattoo-like marking. Occasionally, the user bears some behavioral characteristics of their animal, but this is not common.
All who have such an ability are collectively referred to as +Anima.
The +Anima are capable of controlling their powers at will. Their abilities range widely ≈ including, but not limited to, superhuman strength, agility, and reflexes, as well as heightened senses, and the growth of physical features such as claws or wings. All of these originate from the characteristics of a +Anima's animal. Every +Anima bears the characteristics of only a single animal.
The origin of this phenomenon is unexplained.
The +Anima's powers are not understood by the normal people, and the +Anima are subject to negative prejudice. they are feared as monsters, and even hated by some. Some are envious of such powers and seek to gain control over them. Thus, afraid of the negative reaction from others, most +Anima tend to hide their true powers whenever possible.
This is how life is in this world many live; in this ugly yet beautiful world.
