Shurelia

"I know how I look, but I'm a real administrator!"

A young female artificial life form known as a Reyvateil, created to oversee the Ar Tonelico tower that supports Sol Ciel.
Her unfathomable abilities are such that she alone is capable of managing the tower that supports the entire planet, and she exudes an aura of divinity.
Her actual self is quite awkward, and she seems to be a natural klutz who gets lost, falls down, and causes the most mind-blowing problems.
She also likes the sound of an unusual animal called the Usako.
