You are fated to eventually reprimand the humans for dumping trash into the ocean. They'll face your wrath!

Grow up to be a successful circus performer

You're fated to watch over the little demon in you care until it becomes an adult, and assist you in your travel

You're fated to watch over the little demon in you care until it becomes an adult, and assist you in your travel

You'll be the star in several performance art pieces until you are fated to be discovered and join the big-time. Your face will become so widely known that you will rarely have a moment of privacy or peace again, but you will leverage your fame for good causes and effect a very real difference on the world.

You're fated to be a judge-like being for eternity. You oversee other people's fate but never yours.

your fate is to spend your youthful energy on the pursuit of a dream of fame in entertainment, only to see it gradually fade from your grasp, until you turn your attention aside and take your act to the remote places of the world. Even there you are more novelty, for the remote places have concerns of survival more than entertainment, and gradually your focus will shift, until you become a champion of causes such as access to healthy drinking water, and die remembered as a powerful force for infrastructure establishment.

You're going to spend your life buried in books.

(Kuuki, it's supposed to be the fate of my AVATAR, not MY Fate! ha ha ha ha)

Your fate is to be cursed: you shall become an enchanted seashell for decades. Eventually a hermit crab will use you as a home, and the proximity to your magical aura will grant it speech. It will be brought to the castle because a talking hermit crab is clearly something special, and when it outgrows you, the discarded shell (you) will be taken to Umiel.
That's when he'll figure out there's something up, and disenchant you.

So much time will have passed, your friends and family will be gone, and you'll be adrift, sort of like a time traveler from the past.

To repay Umiel, and for lack of any other option, you'll be stuck acting as his assistant/apprentice for the rest of your life.

It's okay, though. You'll learn a lot of magic yourself, and eventually fall in love with someone who comes to Umiel for help with a spell, and will live happily ever after with them.

You're going to become a real gargoyle and won't be able to move for years.
