Roughly twenty years later, Daisy and the other Monster Makers – sans Shibumi—were reunited by Yamaki and Hypnos, in order to learn more about Digimon, so that they could destroy them. However, when the Juggernaut system failed to destroy Vikaralamon, Yamaki was fired from his position.
Later, when Yamaki made contact with the Tamers, who had travelled to the Digital World to rescue Calumon from the Devas, he called Daisy and the other Monster Makers together again so they could explain the situation to the kids' parents. Daisy and the others then started work on building an ark to bring the kids home. An attack by the D-Reaper on the Hypnos processor almost delayed their plans, but they were able to utilise the processing power of computers from all across the world to finish their calculations and send the ark into the Digital World to bring the children home. But it wasn't over – the D-Reaper followed the kids back through to Earth, and immediately infested the Shinjuku area, causing the Monster Makers and Hypnos staff to flee the building and set up a new temporary base of operations, where Shibumi joined them.
When the ark, which had become sentient, contacted Yamaki via his computer, Yamaki went to Daisy with the information. The Monster Makers then decided to modify the ark into a "battle steed" to help the Tamers – Daisy was the one primarily responsible for designing the ark's new physical appearance, turning it into Grani. It Bio-Emerged just in time to join the battle against the Optimizer. Daisy and Riley then set about modifying Grani and equipping it with the Yuggoth Blaster.
Later, after they had to move out of their temporary base and relocate, the sensors planted within the D-Reaper by Johnny Beckenstein and the Global Taskforce revealed to the Monster Makers that the D-Reaper was a quantum bubble. With this knowledge, they formulated their final strategy against the D-Reaper, Operation: Doodlebug, using MegaGargomon to create a vortex within the D-Reaper's mass and activating the Juggernaut, returning the D-Reaper to the Digital World and devolving it to a harmless state.
