Fei Wong Tomoe Ignacio, Date, Keisuke and Erika Mishima come up with a plan to ambush Ryuji, in which they stall him in Eden and then catch his body in real life whilst he's logged in after Erika hacks to find his position. Fei stalls Arcadiamon and Keisuke and Date track down Ryuji in the real world, however it appears Ryuji was one step ahead of them and the signal sends them to a random hacker instead. When Fei is informed, the Ryuji/Arcadiamon in front of this vanishes, with it merely being a fake. Upon returning to the Hudie base, Ryuji walks in and states that Fei is first on his list to kill, as she was responsible for Chitose being attacked by an Eater, as it was Zaxon's plan to go to Under Zero and that after he's killed Fei, Yuugo Kamishiro was next. Fei is pissed off at the threat to Yuugo's life and her TigerVespamon comes out to help Fei. Erika attempts to calm down her brother but Ryuji just screams at her, saying that him losing all his friends, his family and even Erika herself is her fault. Arcadiamon then digivovles into his Ulitmate form, destroys the Hudie base and flies out into the sky, with Keisuke - who was on his way back - seeing the duo flying off. TigerVespamon manages to save the lives of Fei and Erika whilst the building collapses.
