i think soul when you select while there's no «confrontation» on the match, it becomes like keshin or keshin armed: the animal appears and you just get that shiny aura, but when you need to use a hissatsu, you transform into the animal,  and to use soul hissatsu on the confrontations, you need to use summon soul,  before the confrontation

hope what i wrote is enough for you to understand my though
