Erica

Erica is a Twilight and a "hunter" that works for the Corsica Family. She is Delico's younger sister.

Appearance
Erica is an emotionless young girl who very closely resembles her older brother, so much so they can be mistaken for twins. Unlike her brother both her eyes are dark colored.

She is a female of average height with short blond hair and similarly blond eyelashes which lighten her dark eyes. Her attire consists of an inverted Lolita corset with long sleeves, black shorts and a pair of black high-boots.

Personality
She is utterly expressionless even whilst killing or fighting and is either extremely stoic or unfeeling. It could be said that she completely lacks human emotions, not to mention that she's a person of very few words. She keeps Mikhail on task and reminds him of their orders.

Background
Erica was employed by the Corsica Family to murder Twilights.

Abilities
Erica is a very proficient combatant, able to effortlessly overwhelm and kill most Twilights she encounters. She has gone toe-to-toe with Nicolas twice and both times matched him for most of the battle. When fighting alongside Mikhail, they are a formidable force.

Weapons
She wields a straight-edged blade that lacks a guard.

Trivia

 * It is assumed that Erica is a Twilight, although it hasn't been confirmed. Based on Dr. Theo's analysis of the massacred Twilight bodies, it was assumed their killers (Erica and Mikhail) were also Twilights and, even though Erica has no visible tags, the fact that Delico is her brother further supports the possibility of her being a Twilight.
 * Her status as a Twilight is confirmed in Chapter 3 of the spin-off manga GANGSTA:CURSED.
 * Nicolas noted that she was braver than her brother and quite talented when he encountered her during the "Bastard" massacre.
