This might be similar to an already answered question, but...I know shinki powers only work in vessel form but does that apply to powers that a character has in canon, like magic and such?

For a specific example, my guy here has some limited control over 'darkness' in canon, enough for some attacks and self-buffing. His shinki power is basically the same, only with a greater variety of applications. Would he be able to use the canon-explicit powers or none of them at all in his human form?

I don't want to assume and screw up later.
