Soul/Katagi

Katagi (気質; lit. "Temperament") is the component of one's soul that embodies and contains all of an organism's emotions. As a result of containing these attributes, the Katagi -- being the total sum or a conglomerate of all of a specimen's emotional tendencies and quirks -- also embodies the personality. As with other aspects of the soul, manipulating this quality also has an adverse effect a specimen's persona - giving one the potential to manipulate the emotions of others.

Overview
The Katagi is said to be one of the more complex elements of a sentient soul. This component lingers in close proximity to the Tenmei, and is predicted to be a top layer of the soul. Like a constellation of satellite, the katagi is believed to orbit an individual's soul, and thus it serves to reason that one's emotion or temperament can have an adverse effect on their spirituality.

All of the core emotions are said to exist as sub-Reishi particles that exist within. The amount, or the types, however, aren't fully studied, nor are there many theories on the subject. Nevertheless, it remains certain that this aspect of the spirit completely and utter constitutes the emotional spectrum that a person may be able to experience.

Based on this, scholars determine that certain phenomenons, such as anger breeding ferocious strength, and determination or desperation providing in endurance are as a result of heightened emotions. Given the close proximity to the Tenmei, the Katagi may have a slight effect on one's alignment. Hence the stereotypes of evil beings often being filled with range, and virtuous beings often normally having compassion and patience.
