Acura.

Perhaps Acura is the laziest Keeper of This World. To do business or do something useful she didn't like (although it can, damn it), but that's to do all sorts of stuff she's always first! Although, perhaps, she and the cat, isn't it?..

Sometimes its strange and chaotic decisions even help, but not always. Acura loves attention and affection, the best way to get her to do something - praise or Pat, but to do this in an emergency, no one will.

Can levitate and uses it with or without cause, which is hate Akari ("Everyone's looking at us. You took the form of a pony without wings, so you can't do that, come down.")

Always it turns out in right time in the right place and love seem the strange, confusing other a pony with bribery.

"You know I'm too lazy to go there. I'm sure you'll be able to save the world without my humble assistance" - blatantly pulls Acura, blurring in one of her most cheeky (and disgusting, in the opinion of Akari) smiles. 

Forever stupid jokes even when the situation went to hell the dangerous side, giving hope for the destruction of the world and most Acura's.

Terrible taste in music.
Almost not reads books, but mantra from books on magic not finish reading until the end of (which often becomes a big problem).

Her friends are as stupid as she is. They don't care.

She can't dance, but she likes to.

Perhaps almost never discouraged. Just because she doesn't take anything seriously.
