Following on from the previous volume.
Contains Episodes 13-24
The first half dozen episodes in this volume conclude the Galuna Island arc, with the focus being on Gray and his relationship with Lyon, and his associates. The anime delves into Grays backstory and why Lyon hates Gray so much. Much of this backstory is focused on them as kids, with their mentor Ur.
Also explained is the backstory of Ur/Lyon/Gray and what exactly happened with Deliora.
Featuring lots of action, with Natsu and Gray having much of the screentime with their battles, and of course Erza makes an appearance too.
Following from this arc is the first few episodes of the Phantom Lord arc, Phantom Lord are a guild that come into conflict with Fairy Tail, much of the focus in this arc is on Lucy. This arc is arguably much more enjoyable than the Galuna Island stuff, with many of the other Fairy Tail members having their time to shine, show off their skills, and generally show how likable they are.
This volume is very good, Fairy Tail is a fun series.
