The Digimon Hunt is Booming! The Virtuoso Hunter of the Shopping District!

Synopsis
While hunting a KoZenimon in the DigiQuartz, Tagiru befriends another hunter, Hideaki Mashimo, and his Partner Digimon, Dobermon. Tagiru accepts Hideaki's offer to help catch Zenimon messing with cash registers in the shopping district, agreeing to split the money they receive for "fixing" the registers and letting Tagiru keep all the Zenimon.

While hunting Zenimon, the two stumble upon a Ganemon who claims that the Zenimon are his. They three make a deal to give any Zenimon they catch to Ganemon in order to make more money, and the three continue their hunt. However, unbeknownst to Tagiru and Hideaki, each Zenimon caught carries a few yen coins which they feed to Ganemon, slowing making him bigger and stronger.

After taking a break and watching a takoyaki stand make people happy, the two hunters return to the DigiQuartz and find Ganemon releasing the captured Zenimon back into the shopping district. Confronted, Ganemon explains that his favorite food is the human greed soaked up by money, and that he'll have his Zenimon steal all the money in the world just to fill his appetite.

Ganemon offers that the two hunters continue helping to feed him, since they're just as greedy as him, but Hideaki angrily refuses, claiming he cares more about bringing his customers smiles than money. Tagiru and Hideaki bring out Gumdramon and Dobermon to fight, but all the money Ganemon has eaten makes him too powerful. In addition, the Zenimon swarm against the two hunters, and not even Arresterdramon can keep up with them.

Remembering his Digimon's incredible speed, Hideaki suggests fusing Dobermon and Arresterdramon. With Dobermon's legs and speed, Arresterdramon defeats Ganemon, who is then caught by Hideaki.

With Ganemon's help, the two hunters return all the stolen and swindled money, much to Tagiru's lament.
