a spinoff of the mobile game Puzzle & Dragons for the Nintendo 3DS by GungHo Online Entertainment. It was released in two versions simultaneously on July 28, 2016, named the Gods Chapter (神の章) and the Dragons Chapter (龍の章). An anime adaptation by the studio Pierrot began airing on July 4, 2016.The story takes place in a fantasy world consisting of humans, Dragonoids and Monsters.

Currently, the planet is facing Drop Impacts, occurrences where a large amount of Drops are suddenly generated in a single area (and can also spread), which affects the lands and makes the Monsters berserk. In fact, one of the main duties of Dragon Callers is to settle the Drop Impacts by stabilizing the Drop distribution.
The plot follows Ace, son of King (a powerful Dragon Caller, who is missing right from the beginning of the series) and Rena, who aspires to becomes a Dragon Caller like his father. His journey starts when he starts seeing the Drops and finds an egg of a Tamadra, an almost extinct species and he moves to Dragoza, a region formerly belonging to only Dragonoids, but currently occupied by many Dragon Callers. As the series proceeds, he makes friends with Charo and Tiger, and also many other Dragon Callers, while improving his skills and knowledge. There are also the Ancients, a mix of Dragonoids and Humans, who are the leaders who look after the six regions of Dragoza.
