It would be okay, as long as Rainbow heard what a persona is then her job was done. But to help out, Yukiko pulled out a book that looked homemade and probably a little disheveled. This is what happens when you borrow books from changelings; the little guys gave it to her hoping that she could spread the word about Personas where she went so might as well put it to the test.

"If I were to describe it in one phrase, it would be 'I am Thou, Thou art I...from the Sea of thy Soul I come'. A persona is like an extension of ourselves, a piece of our souls that take shape in the physical world."

And to show an example, she opened the book and turned to two pictures: a pony with question marks around its head and the next one having a huge pony with black coat and mask. Obviously the artist had Yu in mind.

"Personas can be described as either combat or support since they have different skills. It depends on the pony that it comes from."
