Now for a manga spinoff for a change.

Fairy Girls is a bunch of filler side stories to the main manga Fairy Tail, featuring prominently are Erza, Juvia, Lucy and Wendy as they take on various jobs and ultimately get drawn into shenanigans including such situations as looking after a lost baby, infiltrating a school as students, waifu wars as well as many ecchi situations; this among the regular Fairy Tail filler types of poorly constructed villains vs Fairy Tail.
What more could you ask for? Well they chose a guest artist named Boku to draw this version which is fine but Hiro Mashima's style is missed in this.
It's pretty harmless, they chose the timeline between Grand Magic Games and Tartaros which I always considered the point where Fairy Tail peaked, at four volumes it doesn't out stay it's welcome either.
Final Verdict: A nice breather to read before Tartaros arc as I always believed that arc to be brutal and emotionally draining, while the art and situations aren't for everyone it's still a good read.
