Training With My New Ability

A true Soul Spirit had two parts, an Innate Ability and some time of spirit.

The Soul Spirits that Damian copied would become Innate Abilities and the spirit that he copied would be consumed by the copy book to form the Innate Ability.

Utsusu would act as the spirit for all of his Innate Abilities, but it wasn't really needed as unless Damian wanted to unleash more power than his body could handle or evolve the Innate Ability, he would be able to do most other things that he needed to independently.

One's Soul Spirit would be found within the dantian and unlike somebody that had an elemental affinity, the Soul Spirit would have some sort of structure and would be more compressed.

Although, just like an elemental affinity user, there would be a storage of energy within the dantian that would flow around the entire body, an Innate Ability user would also have something additional that represented their Soul Spirit, just like Damian's flame.
