In ages long forgotten, when Earth found itself on a collision course with a meteor, Legendary Pokémon Arceus used its power to avert the danger. However, this feat caused the 16 Plates surrounding it to scatter across the world. Without the Plates providing Arceus with life energy, it began to die. A human named Damon managed to find one of the Plates and returned it to the moribund Pokémon, helping it recover. As a reward, Arceus created the Jewel of Life and gave it to the people of Michina Town, stipulating that it must be returned, but the humans refused, hogging the Jewel to themselves. In the battle that ensued, Damon was killed and Arceus went into slumber, vowing to punish humanity upon its return.

Satoshi and his companions arrive in Michina Town where they come across Sheena, a descendant of Damon, who claims to be in possession of the Jewel of Life and intends on giving it back to Arceus when it awakens.

The situation takes an unexpected turn when Arceus, despite Sheena's best intentions, remains unsatisfied. Satoshi must now prevent the destruction of the entire human race, as Arceus' fury causes distortions in the fabric of the universe, enraging the Legendary trio—Dialga, Palkia, and Giratina—and disturbing the world's balance.

Following Studio Petit's popularity for Time Journey's, the crew is now faced with 3 anime at the same time. Rushing to fill the quotas, the owner of Studio Petit hires Takashimadaira, a veteran producer to help Kuromi. However, all Takashimadaira cares about is making deadlines, severely hurting the quality of the images. Shihonmatsu, who has been helping Kuromi, gets angry at the new producer and leaves, leaving Kuromi with a difficult choice: to choose between the quality or the deadline. Studio Petit managed to survive the production of "Time Journeys," but now that show's finished, and in its place they've got no less than three series to animate, with just four artists, one manager and one director - not to mention one very bedraggled animation runner. And it doesn't help that Shihonmatsu picked this week to quit smoking. As the staff starts to fall behind their crushing deadlines, the owner calls in an old "pro," Takashimadaira, to get production back on track. But once he starts putting speed above quality, the Petit team has to choose between following orders and doing their jobs right.

Papi, the tiny president of a faraway planet, escapes to Earth to avoid being captured by the military forces that took over.

Doraemon, Nobita, Gian, Suneo, and Shizuka start a big adventure as they try to hide and protect Papi. (Source: ANN)
