Pokemon Movie 21: Minna no Monogatari

Synopsis:
Once a year, a "wind festival" is held in Fura City, the city where people live together with the wind. On the final day of the festival, the legendary Pokémon Lugia will appear and give the people the blessed wind, a promise said to date back to the distant past. Risa, a highschooler and Pokémon rookie. Callahan, a braggart that just can't stop telling tall tales. Toren, a timid researcher that lacks confidence. Harriet, an old eccentric that hates Pokémon. Margo, a mysterious little girl that hangs around in the forest all by herself. While they're participating in the festival, Ash and Pikachu meets these five companions by pure coincidence. Each of them has their own worries on their mind, and are unable to take a step forward together with their partner Pokémon, but when they meet each other, the cogs of destiny start turning...... Will the promise with Lugia be kept? And just what is the true identity of the mythical Pokémon Zeraora?
