In a world where only Pokémon live, one Hikozaru wishes to be part of Pukurin Guild—a large area where Exploration Teams gather and work. Intimidated by the apparent strength of the guild members and the guild's security, Hikozaru runs away, stumbling over an unconscious Pochama in the middle of his escape. The Pochama wakes up and is immediately shocked by both a talking Hikozaru as well as his own appearance—because Pochama knows that he is actually a human! With Pochama having no memories aside from previously being human (as well as countless questions about his new body), Hikozaru suggests that he ask the leader of Pukurin Guild for help. While Guildmaster Pukurin may not have answers about Pochama's transformation, he decides to make Pochama and Hikozaru an Exploration Team, which HIkozaru calls Pokédans. For their first mission, the duo must get a Gabite Scale by going to Labyrinth Cave with Kimawari!

In a world where Pokémon live and communicate with each other, there are mythical treasures known as the Time Gears that regulate the flow of time in their respective areas. If one is removed from its resting place, time will freeze in that area, so even evil Pokémon do not dare to steal them. But recently, anomalies in time have been appearing throughout the land, causing the appearance of Mystery Dungeons and violent Pokémon. Pokémon exploration teams have been formed to explore these Mystery Dungeons, arrest the violent Pokémon, and help maintain the peace. It turns out that the anomalies in time have not been caused by the recent disappearance of the Time Gears, but by Temporal Tower slowly falling apart and Dialga corrupting into Dark Dialga. The newly infamous thief Juptile had stolen the Time Gears in order to take them to Temporal Tower and stop its deterioration. The Pokémon exploration team Team Pokédans—which consists of Hikozaru and a once-human Pochama—must team up with Juptile to go to the Phantom Land where Temporal Tower is located. If the trio fails, Temporal Tower will completely collapse, leaving the whole world frozen in time forever...
