About "Error":

-Physical Energy, is the sum of Strength, Speed and Endurance respectively. The 3 are the statistics that consume Physical Energy in a higher proportion. Their maximum potential is also the sum of the potentials possessed by Strength, Speed and Endurance respectively. Physical Energy is life itself, vitality, and if it runs out, the individual in question will die immediately.

-Spiritual Energy measures the size of the soul and quantifies it. It grows throughout life. Its potential is indefinite because the soul itself is something virtually eternal.

-Chakra is the sum of Physical Energy and Spiritual Energy respectively.

-Nature of Chakra is defined by the essence of the body and soul itself. If it exceeds a percentage of 50% then it can be manifested using the Chakra. Except Yin and Yang which require a percentage greater than 90% for manifestation.

--Yin and Yang measure the difference between percentages of the Chakra, be they Spiritual Energy and Physical Energy respectively. They are a framework that defines the balance and harmony within the body.

-Souls, defines how many souls Inai can absorb after touching a recently deceased human being. Souls are used to exchange Soul Points. Souls are reclaimed by the Shinigami if they are not converted into Soul Points after a certain time.

-Soul Points vary according to the size of the soul collected. The larger the soul collected, the greater the amount of soul points that can be exchanged. The soul points serve to increase both physical and spiritual statistics in a proportion equivalent to 30-70%. 30% for physical statistics. 70% for spiritual statistics. This is because "Error" is incomplete. "Error" constitutes primarily a spiritual entity than a physical one.
