Aura

Aura (オーラ) is a particular force produced within all living beings, usually leaking out their bodies in varying amounts. It is a malleable substance with many practical uses; the most prominent being its use in Arts. In combat, the use of aura can enhance the effect of any physical action, resulting in superhuman feats without the aid of Magic or Skills. By observing the potency of a creature's aura, their strength or danger level can be inferred to an extent. Many security constructs within human settlements are built to react to specific auras, usually associated with Monsters. This suggests there are certain qualities not all auras share and can be attributed to certain groups of creatures.
