Erika is a very petite teenage girl with long, deep purple hair reaching down to her waist. She wears the standard Azumi girls' uniform; a white sailor-style blouse with navy blue trim, a white skirt, and a navy sailor necktie with a pink flower at the top. She also wears a black (originally colored purple) petticoat underneath her skirt, black gloves, pink flowers in her hair, and a white beret on her head.
Erika is a selfish and strange girl who acts as if she's a princess that everyone else must obey. Though she claims to be from France, she's actually Tokyo-born. It appears that she has much free time, as she hangs around the Barjona school to make fun of Yamato.
But although she is loud and arrogant on the outside, she actually can't stand to be alone and longs for someone to care about her. She has the strange verbal tic of laughing "Nohohohoho".
