Who is Misa Amane?

Question

Who is Misa Amane?

Answer 1

Misa Amane (弥 海砂, Amane Misa?)

A girl with an immense crush on Kira, Misa is a popular idol in Japan. She is immature and tends to refer to herself in the third person in an attempt to be cute. Misa is completely devoted to Light, and she once said that she loved him at first sight. Light, however, only views her as an asset to his plans because of her Death Note and her Shinigami eyes (that she obtained at the cost of half of her remaining life span, twice). Misa devotes herself to Light because he killed her parents' murderer after several trials had failed to convict him.

Answer 2

She is a small goat of about 30 inches high that plays the piano, BUT ONLY WITH ONE HOOF.

The problem is she can not read music and tends to make it up as she goes along.

Answer 3

It's from the manga DeathNote. If you check it out (and you're into that kind of stuff) you'll find a character with the same name.
