Whilst Jimmy KEN hosts a rally for the members of Demons, Keisuke Amasawa eavesdrops in the distance, hidden from Jimmy KEN, awaiting K. Ryuji and Wormmon plan to hide during their meeting, just to make sure nothing happens to his employee.

After Keisuke refuses, Ryuji forces Keisuke to take him with him as well. This pisses off Ryuji, who then tracks Keisuke down and demands him to cancel the meeting with K. Ryuji however, after finding it suspicious that Keisuke hadn't turned up for work that day, pressures Erika and causes her to reveal Keisuke's plan to meet up with K. Wormmon winds up revealing himself to Keisuke and states that since he's a Digimon, he doesn't count as a 'someone', so it clearly means Keisuke would still be 'going alone'. Wormmon however was sent by Erika Mishima to spy on Keisuke to make sure he was okay. K had told Keisuke to go alone, which he planned to do.

Keisuke however, had already agreed to a meeting with K at the Demon's Den. Zaxon contacts Hudie and tells that that they're attacking the Demons and not to get involved. Before Keisuke can get any more information out of him, Yu deletes his account, removing his only lead on his missing account. Upon defeating him, Akira reveals he did indeed steal Keisuke's account but found the account so boring, he sold it off a long time ago. Eventually, he gives a lead on Akira Hosaka, which leads Keisuke and Yu, who 'happened to be there' when K contacted Keisuke, to fight Akira. Keisuke ignores Ryuji and continues to follow the leads provided by K, which leads him to defeat Youji Shiga and Tooru Kayaba, though neither are shown to have stolen the account. Keisuke follows these leads, though eventually joins hacker team Hudie and Ryuji Mishima attempts to force Keisuke to cut contact with K. K contacts Keisuke with information on hackers that account raid, in an attempt to find out who stole Keisuke's account. In order to fulfill his longing to be with him, Yu becomes a hacker known as K and steals Keisuke's avatar. Yu is in love with Keisuke but Keisuke does not return these feelings. Yu is Keisuke Amasawa childhood, and only, friend and have known each other for over 10 years.
