In the anime, she is also shown to like Musashi, Kairi's Chara. Though Amu doesn't love Kairi herself, he does have a crush on her.
The main ability after Character Change is an increased artistic sense but that power is recklessly abused.
Amu becomes "Amulet Spade" when she Character Transforms with Miki. The clover decoration of her Humpty Lock changes to the color blue. Amu wears a white frilly blouse with a pair of light blue pants. She also wears long, striped stockings and a garter belt; all in a blue themed costume. Her special move is "Colorful Canvas", where she paints with a giant paintbrush. Miki says "Drew, Draw, Drawn" during a Character Transformation with Amu.
