Yōkai

Yōkai are very powerful supernatural sub-species of demons who are often confused for actual demons. Yōkai are born from powerful emotions towards a certain creature, idea, or even an object. This causes the creature to have physical, magical, and sometimes even personality traits that are often associated with that creature, object, or idea and the emotions that created it.

Yōkai Magic
Yōkai Magic a Yōkai's main form of combat and the reason why they are considered a powerful sub-species.

Ayakashi
Ayakashi (妖, Literally meaning: Monster), is the name given to Yōkai who were born from emotions toward a certain animal or object. They are identified by their humanoid appearance with animal features or in the case of an object: physical attributes associated with that object. When an Ayakashi turns twelve they gain the ability to transform into an alternate form that is stronger than their humanoid form and has a more demonic-like appearance. Unlike Mononoke who are known for their intellect, Ayakashi are recognized by their overwhelming physical and magical abilities.

Magical Abilities
Shinobi's belief that magic power comes from within was inspired by the Ayakashi, who's magic power isn't created by Ethernano, but rather is produced from within without any help from the Ethernano in the atmosphere. When an Ayakashi is low on magic power the Ayakashi does the same thing a human would do when if they were low on stamina: they eat and sleep.

Mononoke
Mononoke (物の怪, Literally meaning: Specter) is the name given to Yōkai who were born from the emotions towards an idea or concept. These Yōkai are very intelligent Yōkai who love to use their intelligence to win fights rather than user brute force. Evil Mononoke are said to to be more deceitful than an evil Ayakashi due to their into intellect and wisdom.
