M1918 (Girls' Frontline)'s first skin from Girls' Frontline, as part of the 'Peaceful Days' skin collection from 2016 through shop purchase (being a pre-registration reward for the launch of the EN server).
As the name implies, it is a bunny girl outfit. She retains her usual hairstyle and head shades, all while wearing a black Strapless Leotard with a detached Wing Collar with Necktie, fake bunny ears, Pantyhose and Black Footwear High Heels. She's also seen with a black bunny plush.
