Ki



Ki (気, Qi) is a vital life force that exists in all living beings.

Summary
In several cultures around the Human World, ki is explained as being a life force existing in living beings, but most humans are unaware of its existence. In Japan and China, it is noted for being used in several practices, in which one channel ki for various purposes such as coordinating and cultivating it for health purposes. Ki is also noted as being used by martial artists (those who were able to awaken it) and Japanese Clans found in Shintoism. It is due to humans' physical limits, as such, it was a common practice for them to cultivate their ki to overcome that limit.

Ki can be linked to ones' emotions and willpower as ki tends to flare up whenever their emotions fluctuate towards anger; whenever their willpower is weakened for whatever reason, for example, injuries, then their ki will become weaker than it would in a normal situation.

Abilities
Ki can be used to enhance their physical abilities to superhuman levels with enough training and control, which a lot of martial artists and clans has explored. There are also a number of people who are able to person ki-based attack instead of enhancing their physical abilities. Being a force that also exists in nature, then it is also possible for a person to manifest different elements such as fire and lightning.

Learning
It is not uncommon for humans to be able to awaken their ki and is difficult to invoke without intensive and diligent training, which is most common in martial arts. The far easier form of training for ki is Internal Martial Arts (内家拳, Nèijiāquán) found within China, which trains ones' awareness of the Spirit, Mind, Qi. Ki can also be increased through physical and mental training.

Unlike other kinds of energies, ki is one that remains invisible and unseen, but it is possible to sense it. It cannot be seen by other people when used in higher concentrations forming an aura that is colored white most times for a lot of people including looking almost like steam, ki can also be used to perform ki-based attacks.
