Fairy Tail is the most recent manga by Hiro Mashima, the creator of Rave Master. Like Rave Master, Fairy Tail has also been turned into an anime series, which premiered earlier this fall.
The story revolves around the infamous mage guild of which the manga gets its name and its cast of characters. The main characters are Lucy (a girl who longs to become a full-fledged mage) and Natsu (the wide-eyed, happy-looking hero).
However, the draw of this series for me is the character named Gray. He is thoroughly comfortable without clothes and is prone to removing them at the worst possible times. As you'll see below (and in the rest of the pics), this is something the producers of the anime are really playing up.
The original manga of Fairy Tail is available in America from Del Rey. The anime can be viewed on Crunchyroll but only by paying members.
