Michael knew that he could awaken the talent of someone who hasn't had their awakening yet.
Castelle, for example, missed her timing and was unable to awaken hers, forever closing the door to her latent skills. That was until she met Michael, who had the Supreme Skill to do the impossible.
This happened quite frequently because the fee to awaken a talent was quite exorbitant for struggling families to afford. That was why many people failed to awaken at ten years old.
He had been using his Supreme Skill for demi-humans this whole time, who weren't even supposed to have a talent in the first place. So, Michael had yet to try it on to a human who already had a talent.
Hey ChatJK3, is this possible?
[Yes, Michael. It is possible to awaken the talent of someone who already had a talent awakened.]
Michael couldn't believe it.
