The dormitory at Hazakura Academy, where Hiro and his friends attend, is buzzing with gossip. If you ask first-year, Riku Fukatsu, what you want, he'll deliver it to you the next morning no matter how limited or rare that item is.
Meanwhile, Hiro hears from Espimon a rumor of a strange phenomenon: When a person living in a building hears a strange whispering in the middle of the night, that building shakes. He goes to investigate late at night and sees a single condominium building shaking nearby. He even finds strange rust and cracks within the building.
Hiro talks to Ruli about this, and Ruli tells him that there's been a lot of talk on the internet recently about "Reward Elves," small creatures who deliver things that people want. Hiro begins to suspect a connection between the Reward Elves and Fukatsu. He then checks on a suspicious website that Fukatsu said he'd stumbled on. Come to find out, the site, "MY NO JE LL," is a business that Jellymon and Antylamon started. Seems Antylamon can make anything using the flow of spirit energy, however, they can't create objects from nothing.
After learning about the business from Jellymon, the dorm begins to shake. The students are evacuated. Angoramon believes Antylamon may be absorbing the iron in the buildings, which is causing the rust. Hiro and Jellymon race to Fukatsu's room, but he has run away. Jellymon demands that the orders be canceled. Antylamon says the orders cannot be canceled. unless they go thru the proper channels. Worse, he threatens her if she interferes.
The Antylamon increase in size. Hiro engages the Digital World. Gammamon evolves to Betelgammamon. Ruli arrives. Angoramon evolves to Symbaangoramon. Unfortunately, the Antylamon are very strong. Betelgammamon super evolves to Canoweissmon! Symbaangoramon super evolves to Lamortmon! Any damage the Antylamon take are erased with "Meditation Cure!" Thankfully, Jellymon was able to get a hold of Fukatsu's PC and cancel the orders just in time!
Kiyoshiro returns from his business trip to find the dorm in a shambles. Hiro asks that the Antylamon fix the dorm, and they do using the rare items ordered by the students. The Antylamon say they just wanted to make people happy. Kiyoshiro takes them to a recycling center he's involved with. He offers the materials from there making everyone happy.
