Lost in Digital Space.After a brief talk with Mikey Kudo, Nene Amano still needs to find her younger brother named Ewan Amano. Nene discovers that her Black Fusion Loader is no longer working. Nene collapses from fatigue. Needing to get her some help, Mikey Kudo, Angie Hinomoto, and Jeremy Tsurgi decide to take Nene to the Monitamons' home in the Warrior Zone. While traveling between the zones, the Fusion Fighters are attacked by the legendary Digimon named Arukadhimon. While the other Fusion Fighters and Mikey’s Fusion Loader are sucked into Arukadhimon's subspace, Mikey learns the attack was arranged by Laylamon to make him suffer as he is thrown to float in digital space. However, Mikey encounters a strange book and meets its occupant named Wisemon who attempts to dissect him before convincing the Digimon not to. Mikey soon learns more about the Digital World. Mikey also learns how the strange events happening in his world are a prelude to what will happen once Bagramon has all the Code Crowns from the 108 Digital Zones. Mikey attempts to convince Wisemon to help him save his friends. However, Wisemon explains it is illogical. Mikey is forced to go on his own. Despite Wisemon not removing the ball and chain he placed on Mikey, Mikey reaches Arukadhimon's subspace as Shoutmon and the others barricade themselves in the monster's nest to keep him from eating them. Sacrificing Wisemon’s book home after a change of heart, Wisemon saves Mikey as he regains his Fusion Loader and forms Shoutmon ×5 so he and the others can make their escape. Arukadhimon attempts to stop them from escaping. Arukadhimon is finally destroyed by Shoutmon ×5 after Mikey uses the Darkdramon DigiCard that Jeremy attempted to use earlier. As Laylamon arrives, she is enraged to find Arukadhimon defeated. Wisemon joins the Fusion Fighters as they arrive in the Warrior Zone. The Fusion Fighters are greeted by a clan of Monitamon.
