M1919A4 (Girls' Frontline)'s first skin from Girls' Frontline, as part of the 'Halloween Carnival' skin collection from 2016.
It's a sexy Vampire costume, whose appearances can massively shift depending on whether the censorship is turned on. With it off, she wears a scantily-clad Leotard with cutouts, a Cape, and Wrist Cuffs, as well as a Skull Hair Ornament. With the censor on, she receives a Bodysuit underneath the leotard.
