Hidden powers unlock when a spirit is enhanced by the same exact evolution of said spirit. You can unlock powers before fully evolved and they carry over through evolutions. I was fortunate enough to have Yui drop twice so I used the extra two  to enhance her during her first evo and unlock two hidden powers before I evolved her.
