Pokemon Fushigi no Dungeon: Sora no Tankentai - Toki to Yami wo Meguru Saigo no Bouken

In a world inhabited entirely by Pokémon, mysterious Time Gears keep time flowing in the regions around them. Strange distortions have begun spreading across the land, creating Mystery Dungeons and driving some Pokémon into violent behavior, while the gears themselves start disappearing from their sacred places.

Hikozaru and Pochama, a Pokémon who was once human, learn that the apparent thief Juptile is stealing the Time Gears for a reason far greater than greed: Temporal Tower is collapsing, and Dialga is being consumed by darkness. The three must reach the Hidden Land and restore the gears before the tower falls completely and freezes the entire world in an endless instant.
