When hired to try and deal with an Idol, who abused her fans for money, Keisuke finds out it is a Lotosmon in disguise, who mind controls her fans to steal their credit card information by having the person the mind controlled is in love with trick them into giving away the information. This even works on Keisuke, who gets mind controlled, his thoughts manifesting Lotosmon as a fake version of Erika, who states she will be his girlfriend if he gives away his credit card information. Keisuke is half way through doing so, before the real Erika arrives and slaps him, snapping him out of it. The duo then proceed to defeat the Lotosmon. When Erika asks Keisuke what he saw that nearly caused him to give away his credit information, he avoids the question, not wanting to admit his crush on Erika to Erika herself.

Digimon Story: Cyber Sleuth - Hacker's Memory
Keisuke Amasawa was accused of a crime he didn't commit, which lead to him dropping out of school, the only person left trusting him being his childhood friend, Yu Nogi. Keisuke's Eden account had been stolen, so Keisuke goes on a journey to find out who stole his account. Using information provided by a mysterious hacker known as K, he attempts to track down his missing account. He finds himself at a place known as the Digi-Market, in which he starts to ask around and not wanting to seem out of place, attempts to buy a Digimon, however he barely has any money, meaning he can only buy one of the worst Digimon they have, which were going to be deleted anyway - one of Gotsumon, Tentomon or Betamon. Keisuke chooses one to buy, though before he does, he demands the salesman let the other two go instead of deleting them. The salesman becomes angry at Keisuke for demanding such a thing, so summons his Ogremon and Devimon to attack Keisuke. Ryuji Mishima and Cyberdramon appear to defend Keisuke and the chosen Digimon runs in to try and help defend Keisuke too. Seeing this, Ryuji adds the Digimon capture program to Keisuke's Digivice which allows Keisuke to capture the Digimon. They then team up and defeat the salesman, then force him to release the other two Digimon back into the wild. Ryuji then offers Keisuke a job as a member of Hudie, which Keisuke accepts, making him team mates with Ryuji, Chitose Imai and Erika Mishima. Hudie works directly under Yuugo Kamashiro's Zaxon, doing various missions for the group, usually being assigned them by second in command, Fei Wong Tomoe Ignacio. Hudie also directly get involved, sometimes helping and sometimes unintentionally making things worse for them, with the various missions of Aiba and their friends, Nokia Shiramine, Arata Sanada, Kyoko Kuremi, Yuuko Kamishiro, Makiko Date, Gorou Matayoshi and Mirei Mikagura as well as Aiba's enemies, Jimmy KEN, Akemi Suedou and Rie Kishibe - Keisuke however, is on friendly terms with Jimmy Ken and Suedou and considers them friends. Keisuke also finds himself involved with the Royal Knights and Seven Deadly Demons, though unlike Aiba who becomes acquainted with every single member of both group, Keisuke only befriends Omnimon, Alphamon, Veevee, Craniamon and Beelzemon, whilst Crusadermon is a direct enemy to both Keisuke and Aiba. Despite befriending all of Aiba friends, Keisuke himself never meets Aiba.
Following the leads of K, Keisuke deals with various hackers and eventually finds out that K himself was responsible for stealing Keisuke's account and had been using it the entire time. Keisuke later learns that K was actually his best friend, Yu, who was madly in love with Keisuke and was being manipulated into doing evil things to get Keisuke's attention by a Matadormon posing as a mask. Keisuke defeats the Matadormon, freeing Yu from it's clutches, though Yu, embarrassed by everything he's done ignores Keisuke.
Similar to Aiba and their friends, Hudie also had to deal with the Eaters. In Under Zero, Crusadermon summons a giant group of them, which attack countless numbers of hackers, causing them to acquire EDEN Syndrome. Ryuji is seconds away from being attacked, being pushed out of the way at the last second by his best friend, Chitose. This shocks the leader of Hudie, who goes into a deep depression from seeing his best friend sacrifice himself for him. This dark depression winds up attracting the attention of Arcadiamon, who teams up with Ryuji in his mission to murder all hackers as revenge for Chitose's sacrifice. Ryuji would kill the hackers, whilst Arcaidamon would kill their Digimon. Digivolving all the way up to the Mega level, whilst absorbing multiple Digimon and humans, Ryuji and Arcadiamon cause massive trouble all over Eden and the real world. Whilst doing so, Erika tasks Keisuke to track down an Eater. After defeating it, they hack it and use it's data to reach the Eaters home world, where they come across the real Yuugo Kamishiro. Explaining that they had come to locate Chitose's memory data, Yuugo allows them to do so, which they find due to the help of Chitose's Ankylomon. They restore Chitose's mental data, causing him to be the only person to awaken from Eden Syndrome. Keisuke attempts to inform Ryuji, only for Ryuji not to believe him, leading to Keisuke defeating Arcadiamon. Chitose then arrives and yells at Ryuji for his actions, the shock of Chitose actually being back alive shocking Ryuji out of his depression. However, Arcaidamon has woken back up and attempts to murder Chitose. Like Chitose had done before, Ryuji pushes Chitose out of the way and takes the attack instead, before flying off to Odaiba. Keisuke and Erika locate Arcadiamon, who was now in it's Ultra stage. They are unable to harm it, leading Erika to have her Eater Bits, which she had created using the previous hacked Eater data, attack it which slows it down enough to harm it. Keisuke then kills Arcadiamon, freeing Ryuji and Cyberdramon. Erika however had overexerted herself and passes out, which leads to her Eater Bits attacking her and merging with her to become Eater Legion.
Eater Legion attempts to get to the Digital World, as do the massive amount of Eaters, which causes EDEN to shut down. Needing to get into Eden to free Erika, Fei allows Hudie to use Yuuko's personal EDEN computer, which with the help of Yu and the various hacker groups Keisuke had fought against, manage to gain access, though only enough power existed to allow Keisuke, Chitose and Ryuji to enter. Finding Eden to be infested with countless amount of Eaters, they fight their way through, eventually finding Eater Legion. They attempt to defeat it without killing the body, but this proves to be impossible and Erika instructs them to kill Eater Legion as her body was too assimilated with it. Erika's non corrupted memory data from her server merges with her Wormmon to become Hudiemon and she aids in killing her original body. A large group of Eaters then merge with the rest of her corrupted memory banks, creating Eater EDEN, which Hudie manage to kill as well. Due to the actions of Aiba in the Digital World, the world is reset and changed so that EDEN never existed, which in turn means that Digimon never arrived in the real world to interact with humans. Erika makes the choice to remain as Hudiemon, rather than return as Erika because should she return to a human world without EDEN, she will die due to EDEN being the only reason she was still alive. In addition, she was directly responsible for the death of her parents in a car crash, which is what caused her illness in the first place, so erasing herself out of existence will not only remove all burdens from her brother but will also cause her parents to stay alive. Keisuke leaves his Digimon with Erika, as do Chitose and Ryuji. Hudie return to the real world, with their memories of Digimon and Erika erased. With no Erika in the new world, Ryuji is an only child with his parents still alive. He still however, is the leader of Hudie - with Chitose and Keisuke working for him. Without the influence of Matadormon, Yu is also a member of Hudie and remains on good terms with Keisuke. Unlike the rest of the group however, Keisuke retains his memories and cries in what used to be Erika's bedroom.
Digimon Story: Cyber Sleuth - Hacker's Memory (Manga)
Keisuke Amasawa goes to the DigiMarket, where he remembers how he got his partners, Betamon, Tentomon and Gotsumon. Not happy, he challenges the owners of the market and has to fight against their Triceramon, Tyrannomon and Monochromon. Keisuke is close to losing, only for his partners to digivolve to Seadramon, Kabuterimon and Golemon. Ryuji Mishima, Chitose Imai, Erika Mishima and Wormmon arrive and Ryuji has his Cyberdramon help fight. They defeat the hackers, then force them to release all the Digimon they were keeping locked in cages.
The Zaxon hires Hudie to infiltrate Kamashiro's Server in order to find any hidden secrets of the company, leading to a a mission for Chitose Imai and Keisuke to convince and gain access to Yuuko's account. Chitose tries to flirt with her, an fails, but Keisuke succeeded by accompanying her to a restaurant at Nakano Broadway and helping her eat a gigantic rice ball. However Yuuko states that Yuugo has contacted her and is already aware of their plans. Keisuke logs into Yuuko's account and realizes he is now Yuuko while Wormmon hangs onto his back. Before he can do anything, Erika Mishima quickly calls and tells Keisuke that she'll kill him if he attempts to do anything dirty, and that Wormmon will see him through the end of their mission. Keisuke accesses Kamishiro's server but finds Rie Kishibe is also there. When she asks why Yuuko is also there, Keisuke responds with: "I am tired and ended up here by accident". Rie accepts his answer and leaves the server allowing Keisuke to download all the hidden information on the server. After that, he leaves the server and gives Yuuko back the access for her account
Ryuji Mishima come back to Net Cafe Hudie to give their team info for their newest mission: to infiltrate the Tokyo Metropolitan Police Server. The group come up with a plan to have Keisuke pretend to be a Poyomon with malware installed. Inside EDEN, Ryuji would lure Matayoshi while Keisuke would try to 'accidentally' touch the latter, which would copy the access rights of the detective's avatar to Erika and to be used later on by Keisuke. They ask Yu Nogi to pretend that Poyomon is his pet and access that server. They meet up with Matayoshi, but before Keisuke can touch him, Makiko Date steps in the way, noting Poyomon's cuteness and hugs him tightly to her chest, prompting Erika to call a Keisuke a "Perv". Matayoshi, Date and Ryuji take off to pursue a fugitive hacker and Keisuke follows them. After Ryuji and Keisuke defeat the hacker, they are still unable to gain Matayoshi's access, however Erika was able to copy the access rights of Date's account, which is sufficient for their next mission.
