By day, I am the Cedric Morvain you know. By night, you call me the Phantom Thief Raven.
Same face, same voice, same heart. It's just that the side I show you is different.
Laughing with you in the daylight, being chased by you in the dark. Both of these times have become irreplaceable to me.

Day or night, I want to be by your side. My former self would never have imagined harboring such a wish.
