THis was my first officially long Anime Series.
The story is very interesting, with some unexpected twists, the characters are great, there is prominent (non-Ecchi) fan service, and great action. this series has everything. Magic, Heroes, Swords, Magica powered Transport, Main character (OP but with some flaws), Magical Guilds, Underdogs, Teams, Awesome Flying Cats (HAPPY :D ), Dragons, Warriors, mages, Witches, Mystery, Time Travel, Alternate dimensions, Supreme beings, summoners, celestial gods, zodiak, villains and demons, and so much more!!!!!
If you are unsure of this anime, just watch first few episodes, and you will be hooked. Great story with a little for everyone, and you will fall in love with the characters from the start.
OVERALL: One of all time Greatest Anime (its up with Naruto, DBZ, Fullmetal) It has great character development, The art is amazing, the stories are well thought out and enjoyable. MUST WATCH!!!!
