They're last mentioned to join the fight in Chapter 453, but after that, they're forgotten for the next 21 chapters.

Knowing that their primary objective is to quote eradicate all evil brought about by (Dark Guilds and) Zeref unquote, what I want to see next is Jellal confronting Zeref now that he finally appeared in Chapter 474.
