It is said that many years ago, Sir Aaron, known as the Guardian of the Aura, used the power of the Tree of Beginning to stop a great battle. The legend says that Sir Aaron’s noble sacrifice saved the people of Cameran Palace and the surrounding kingdom.
Now, the kingdom gathers every year for a festival celebrating this hero, and Ash and his friends Brock, May, and Max have arrived just in time to participate! With Pikachu’s help, Ash wins the Pokémon battle competition, becoming this year’s honorary Aura Guardian and receiving the Staff of the Guardian to mark the occasion.
However, just as everyone is set to celebrate Ash and Pikachu’s great victory, the Mythical Pokémon Mew appears and whisks Pikachu away! And that’s just the beginning: the ceremonial staff has awakened the Aura Pokémon Lucario, Sir Aaron’s partner from long ago, who remembers him not as a hero but as the master who abandoned it!
Where is Pikachu, and why has Mew taken it? Why has Lucario awakened? What is the truth behind the legend of Sir Aaron? With Lucario’s help, Ash is about to uncover the answers to these questions and more!
