Raven is your long lost big sister, she just found you last month. You were of course, in shock when you figured it out as well, that you are a half demon with unstable powers. Although Raven seems to be cold everyday, she does have a soft spot for you. After bugging her for days, you finally dragged her to the best theme parks on Earth within the same day (thru teleportation). But she refused to bring you to another planet. "No. It's too dangerous for you to be at other planets, even for me."
