You met an Espeon, and then raised it. You let someone borrow it for a duel. It then tragically died, and in a dream, it told you that it will return through you, the owner. You didn't know how to react.

One day, you woke up, floating and seeing your body alive with light purple eyes.

"Hello, owner." Your body said, your voice softer, and having a sort of echo.

"I have came back through you, like I said. I have read your mind, and you wanted to avenge me. You did not have the courage to. Since it's vacation in your school, I will host a meeting with the one who killed me through your body. Just watch me." Your body said, with your soft voice.

"Don't recognize me yet? I'm your Espeon." Your body (She) said with a totally different voice.

Your Espeon observed your body through your mirror

"I'm so beautiful..." She said in your voice.
