A silent but deadly yokai that walks through the shadows in order to strike quickly at its enemies and then make its escape.
Despite its dark design, Shadow is not a particularly violent yokai. Shadow was drawn to Ade’s large ki reserves and simply followed the young Tennin’s shadow for weeks before he noticed the shadow yokai feeding off of the excess ki rolling off of him. When Shadow made no move to attack, Ade proposed an agreement in which he would periodically give up a portion of his ki in exchange for Shadow’s assistance. This has proved useful as what Shadow lacks in combat skills, it more than makes up for with its skills in reconnaissance and quick travel.
