Erika

Erika is a young woman with a curvy figure and long brown hair, usually seen in a flowing dress paired with a necklace and dark heels.

At first Erika comes across as cold, toying with Feather and belittling his heroics, yet the tears she hides once she turns away reveal a pang of guilt. After Tatsumaki rescues her from Big Iron, she becomes a fan of the S-Class hero and resolves to write her a letter.

The Iron Fist gang of N-City spreads word that a woman named Erika has been taken hostage. Feather, an A-Class hero and her boyfriend, storms the gang's base and downs many of its members but is left wounded and nearly beaten. To rub in his defeat, the gang parades Erika out, and she coldly claims she deceived him the whole time and is really the girlfriend of their leader, Big Iron. Feather laughs off her act as poor acting, pointing to the tear she sheds as she turns aside, and tries to fight on, only to be knocked down by Tatsumaki and Saitama, who have smashed through the wall behind him. When the gang turns on the S-Class heroes and is crushed, Erika watches the collapse with her own eyes, deeply touched by Tatsumaki and vowing to send a note of thanks. As an ordinary civilian, she has no abilities beyond those of a normal person.
