As a result of his excellent performance, his Balancer grade was reevaluated and he was promoted.
Sloane became known as a B-grade Balancer which showed that he was quite a talent and a valuable member to be had in any organization.
The only ranks above B-grade for Balancers were those who had surpassed the normal limits and stepped into realms where they could contend with A-grade Spirits alone or as part of a small unit.
It was a grade just below when the threat level of Spirits rose significantly.
A-grade was when Balancers started to gain an understanding of Life Energy and gained better control over it.
It was also when Spirits started to get closer to their most ideal form and more often manifested some form of unique ability or power.
