Digimon Story: Cyber Sleuth - Hacker's Memory
Ryuji Mishima is the leader of Hacker Team Hudie, a handyman group that solves cases both of Hacker's and Eden users. He is the older brother of Erika Mishima. His Digimon partner is Cyberdramon, which is his most powerful ally. Their main mission contractor is the Zaxon who is the Hacker Team lead by Yuugo Kamishiro, and infultra turn also adds Rie Kishibe as a secret contractor.

Ryuji was originally a member of Jude back when Digimon and Digimon capture was not yet founded. He was the right hand man of Arata Sanada and best friends with Chitose Imai. The Jude was disbanded after their defeat on the Ground Zero together with Arata's disappearance and Ryuji's incompetence to be the team's new Leader. After that Ryuji held a grudge towards Arata and seek to not forgive him even if the latter wanted.

After their parent's death and an irregular disease of Erika, Ryuji secretly seeks the assistance of Kamishiro Enterprise and Rie Kishibe. Erika's treatments were funded by the company with the cost of Ryuji doing the dirty works for Kishibe's schemes.

Ryuji was ordered by Rie to watch the hackers invading Ground Zero. He was stopped by Keisuke and Chitose, however Crusadermon suddenly spawned a massive group of Eaters to attack all the hackers. One of the eaters suddenly attacks Ryuji, only for Chitose to take the blow instead, leading Chitose to contract Eden Symdrome. Ryuji is disraught and spends hours standing alone in Under Zero. This winds up catching the attention of Arcadiamon, who nearly absorbs Ryuji, only for Cyberdramon to protect his partner. Ryuji is shocked, though he winds up being enveloped by a dark aura. Soon after absorbing Cyberdramon, Arcadiamon digivolves into his Rookie form. On Kowloon Lv.1, Ryuji orders him to attack Takkun and Miporin.

When Keisuke Amasawa is about to lose to K and his SkullSatamon, Ryuji and Arcadiamon (Rookie) easily defeats and absorbs it. They then go on a rampage, absorbing all sorts of Digimon all over Eden and the real world, in an attempt to eliminate all hackers in the world as revenge for an Eater eating Chitose Imai. After absorbing an IceDevimon it digivolves into its Champion form. Keisuke arrives to confront Ryuji but he just walks off. 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.

Keisuke eventually finds Ryuji and Arcadiamon (Ultimate) in Akihabara. Keisuke tells Ryuji that Chitose is now awake, as he and Erika had hacked an Eater, gone to the Eater World and acquired Chitose's data, allowing them to restore him out of his Eden Syndrome. Ryuji doesn't believe Keisuke and Wormmon and then states the two had betrayed him and attack the duo. After Keisuke manages to defeat Arcadiamon, Ryuji flees to find more Digimon to have his Arcadiamon eat so power back up. At this point, Arata Sanada in his Eater forms arrives and the three team up, searching the Akihabara Digital Shift. They find Ryuji has caused it to be an endless loop, so hack the environment and find that three random hackers have been mind controlled to cause it. After defeating them in a domination battle, the area is restored to normal and the three find Ryuji with Arcadiamon eating multiple Digimon to power back up. Ryuji then sees Arata and states that Keisuke has betrayed him after all, since he is now teaming with the guy who betrayed Ryuji by leaving Jude. Ryuji and Arata argue over it and when Arata states that it's Ryuji's fault Jude ended because he could've just continued without Arata there, Ryuji's anger causes Arcadiamon to digivolve into his Mega level. Keisuke and Arata manage to defeat Arcadiamon, leading Arata to reveal he left Jude because in the past he got friends killed and losing in Under Zero brought those memories back. He didn't want to lead any other friends into getting killed again and that he knew Ryuji would force him to be the leader again and that Ryuji would've been a good leader for Jude, due to how well he had been leading Hudie until he and Arcadiamon started murdering hackers. Arata then leaves, with Ryuji in shock. Suddenly, Chitose and Matayoshi arrive with Ryuji being amazed that Chitose is awake like Keisuke had claimed. The dark aura suddenly vanishes from around Ryuji as he's happy to see his best friend alive. Just as Ryuji states he's done too much to ever return to Hudie though, Chitose is pissed and throws Wormmon at Ryuji, screaming at him about how Ryuji has been an idiot in his actions and that attacking Zaxon pretty much screws over Hudie. After getting everything out, Chitose asks for Ryuji to return though before he can, Arcadiamon wakes up and attempts to murder Chitose. Ryuji dives in the way, protecting him in the same way Chitose had done before, leaving Ryuji to take the blow and get absobred by Arcadiamon, who then flies off with Keisuke, Chitose, Wormmon and Matayoshi shocked. Ryuji is able to talk to Arcadiamon whilst inside him with Arcadiamon stating that he will destroy Ryuji before anyone else can and before his friends abandon him for what he has done. Ryuji apologises for making his partner the way he is, though Arcadiamon still tries to kill Ryuji. Cyberdramon suddenly appears and blocks the attack, with Ryuji happy to see his old partner survive. They then decide they need to return to Hudie.

After having absorbed Ryuji, Arcadiamon is shown appearing from inside a lake in Odaiba in his Ultra form. Keisuke and Erika arrive to try and fight it but find their Digimon unable to hurt the building sized monster. With no way to win, Wormmon wants to flee, only for Erika to send her Eater Bits to attack it instead. This slows down Arcadiamon, with Keisuke's Digimon now able to hurt the giant Digimon. They manage to defeat it after a long fought battle. After being defeated, Arcadiamon explodes with Ryuji and Cyberdamon being released in the air. Cyberdramon flies Ryuji down to the bridge, with Makiko Date charging in to arrest him, though changing her mind when seeing him injured, instead getting him am ambulance. Erika then collapses due to overexerting herself, which leads to her baby Eaters attacking her, merging with he body to create Eater Legion and then flying off, with everyone shocked at what just happened. As a result of what he had done, Ryuji decides to leave his post for a while as the leader of their group and gave the leadership role to Keisuke. He then stands in Ikebukuro and demands for all of the hackers to beat him up for what he had done. They refuse though, so he then demands for Cyberdramon to beat him up instead. At this point, Fei Wong Tomoe Ignacio and TigerVespamon arrive and she states she will fight Ryuji to teach him a lesson, though he only needs to return to his old self to truly apologise. When he realises this is the truth, he decides to return to his old ways. This then leads to Cyberdramon digivolving into Justimon. Ryuji, Chitose Imai and Keisuke Amasawa then defeat Fei and two other hackers in a Domination Battle then decide it's time to go rescue his sister.

Just as they plan to rescue Erika however, they find that Eden is no longer accessible, as Eater Legion had caused thousands of Eaters to appear there. They then decide to infiltrate the Metropolitan Underground Laboratory to hack the machine Yuuko Kamishiro used to act as Yuugo, as it allows access to Eden. Ryuji accompanies Chitose, Wormmon, and Keisuke to save Erika however she states it is too late and that she is fully assimilated with it and tells the boys to kill the eater. Suddenly Erika's memory banks appears as Erika, then fuses with Wormmon to create Hudiemon. Hudiemon helps to kill Eater Legion and then Eater EDEN who also merges with some of Erika's memory bank data right after Legion's defeat. Just as they're all reunited, the world suddenly starts to reset as Aiba and her friends had saved the world. Hudiemon states that as a Digimon, so can no longer return with them and will instead go to the Digital World. She states that if she does return, she will just die soon anyway so will prefer to live her life as a Digimon. Everyone has a tearful goodbye, with the world reseting to cause humans and Digimon to never meet. In the alternate universe, Ryuji is an only child and celebrates getting a job with Kamashiro. Yu Nogi is now a member of Hudie and Keisuke, Chitose and Ryuji ended up all being friends anyway. None of them retain their memories of Erika, though Keisuke is implied to have when he opens what used to be her bed room and begins to cry.
