it's frustrating that Crime Sorcière hasn't appeared since Chapter 416 (the entire group), and Chapter 444 (Sorano). And they're last mentioned to be joining the battle in Chapter 453, but after that they've seem to be forgotten and now it's 2016 and they haven't been utilized, but since this a battle against Zeref, They must come since "The guild's primary objective is to eradicate all evil brought about by Dark Guilds and Zeref".
