Yokai Watch Girl

Dr. Fuji, a research scientist of Team Rocket, briefly describes in a prologue how his researchers uncovered a fossil of the remnants of Mew, one of the rarest Pokémon in existence, believed to be extinct (although this is not the case).

The film's setting is in the water-themed Johto city of Altomare (which means "High Sea"), based on Venice, Italy. The city is watched over by two legendary Pokémon, Latias and Latios.

The story revolves around the Millennium Comet, which appears in the night sky for seven days once every thousand years. It is, at the same time, when the legendary Pokémon Jirachi awakens from a long slumber to absorb the comet's energy.

One night out at sea, a mysterious Pokémon egg washes into a massive ship led by Phantom the Pirate. As Phantom is about to hatch the egg for his desires, one of his ship employees steps in, snatches the egg, and escapes the ship, being none other than a Pokémon ranger using his capture styler to make a clean getaway with a Mantine.

The Team Rocket leader, Giovanni, has found Mewtwo in a remote area of the Johto region. As Giovanni tries to re-capture Mewtwo, Ash and his friends are kidnapped by Domino, a new Team Rocket member, while trying to rescue Pikachu from Jessie and James.

One day, while searching for bugs in the woods, a boy named Nate (Keita in Japan) comes across a peculiar capsule machine next to a sacred tree. When he opens one of the capsules up, it brings forth the Yo-Kai Whisper, who gives Nate a device known as the Yo-Kai Watch.

Ash is a young boy who has always dreamed of becoming a Pokemon trainer. At age 11 he is gifted his first Pokemon, Pikachu, from Professor Oak.
