Plot
Hirose searches for the location of Chief Karasuma with Kenzaki continuously asking where he is. She tells him she can't get in because she cannot figure out the password. The hologram begins to glitch and shuts off.

Tachibana who is hiding the Chief in a building, is trying to figure out how to wake him up himself in order to ask him numerous questions. He starts to cough and then dreams of turning into a green monster and disappearing. He leaves the room. Hirose continues attempting to crack the password but is not having any success. Kotarou suggests trying his computer downstairs as it holds data on BOARD and could provide hints as to what the password is. Kenzaki agrees to try it.

At the Jacaranda, Amane questions why the appearance of the Undead at the Observatory wasn't included in the newspaper. Her mother (Haruka) explains that the police say that they still investigating. Hajime tells Amane that humans are like that: They don't acknowledge what they are unable to understand and that they prefer to remain in the dark about it. Amane tells him that he is acting like he isnt human. Hajime tells her jokingly that he is a monster and attempts to scare her. Amane tells him that even if he was a monster, she would be fine with that. Haruka tells her to go do her homework. Haruka thanks Hajime for coming when he did as she couldn't really tell Amane the truth about her father. Hajime freezes for a few seconds while she tells him that when he died, she became depressed. She asks him what is wrong but he says that nothing is wrong. Hajime leaves for his room and finds Amane in there. She asks him if he is trying to be a great photographer like her father. He doubts his talents but she disagrees and tells him that she thinks he is similar to her father. She questions why her father died. Hajime remembers back to a time when he was in the middle of a blizzard. A man (Amane's Father) who is dying, holds out a photo of his family for Hajime to take. Amane drops the conversation and goes to bed. Hajime pictures a monster calling for him.

At a house, A female doctor tells Tachibana that one again, there is nothing wrong with him. He tells her about the dream and how it is getting stronger. She asks him he had been participating in any experiments at board. Tachibana tells her that he has, and that the originally believed that it was for the sake of humanity, but in the end, it was a cover-up and that he was just being used. The woman tries to get more information out of him but he falls asleep rather quickly. She reveals that she was one of Tachibana's classmates and that him coming to visit her was good.

Hirose continues to type in passwords overnight to no avail. Kotarou comes and tells her to stop trying to find it because they need to eat. Hirose thinks that she nearly has it and types in the phrase "Double J". Meanwhile, just as Tachibana is leaving the doctor, he tracks an Undead from his cell-phone. Hirose manages to crack the password. she says that in Kotarou's Research, there was an assumption of a Trump and that Double Joker is it. They type it in and it works perfectly, restoring the hologram of Chief Karasuma.

The Undead that Hajime pictured before appears and kills a few workers at a dam. Tachibana intercepts the monster telling himself in the process that if he doesn't fight, he doesn't believe his body will recover from the issues that it has.

Karasuma telepathically speaks to the three and congratulates Hirose on finding him. She asks him where he currently is, however, he doesn't know where he is either. He tells them however the story of the Undead. He tells them that 10,000 years ago, there were 53 Undead and that in the pursuit of an immortal body, a battle began to find a winner. Humans won and the other 52 Undead were sealed in Cards. He tells them that 3 years ago however, the seal was removed and instead of beginning another battle, the Undead strayed from their original path and fought rather to eradicate humanity instead. He explains that it is the purpose of the rider system, to seal the Undead.

Hirose asks him why the Undead were unsealed in the first place. Karasuma takes full responsibility for it just as the hologram glitches out. Kenzaki gets angry at Kotarou for wasting the Chief's Time with Pointless questions. Hirose and Kenzaki theorize that Tachibana must be hiding Karasuma and that Tachibana might have been the one that undid the seal on the Undead. Hirose tells Kenzaki however that saving Karasuma is their priority. Tachibana continues to battle the monster, but it jumps away. Tachibana cancels his transformation and chases it on his bike.

Hirose, Kenzaki & Kotarou all go to the Building where the First Humanity's Foundation lab was. The lab was abandoned two years ago. Kotarou attempts to link together the unsealing of the dead (3 years ago) and the abandoning of the lab (2 Years ago). Kenzaki, who is still annoyed at Kotarou stares at him grimly as if warning him against saying something stupid. Kotarou asks him why he became a rider but once again gets stared at grimly by Kenzaki. Hirose tells Kotarou that Kenzaki was scouted and tells him that Tachibana, who was a Research became the user of the Original Garren System. However, Karasuma did not believe it was enough and after creating the Blade System, searched for a person who would be able to use it. Kotarou unintentionally questions Kenzaki being the best person for the Blade System which once again attains staring from Kenzaki. Hirose tells them to search as it is like that Tachibana hid the Chief somewhere in the lab. Just as they begin to search, Hirose gets alerted by the Undead Tracker. Kenzaki rides off to fight the monster with Kotarou and Hirose attempting to follow closely behind. However, Kotarou's car fails to start.

Kenzaki tells himself that he doesn't matter who it is that released the dead, what matters is that he defeats them. He transforms and continues to rider to his destination. Tachibana continues to chase the Undead and transforms to fight it. After causing lightning bolts to hit around Tachibana, the Undead begins to take control while Tachibana rolls down a hill. Kenzaki appears right at that moment and goes to help Tachibana who instead tell shim to say back, saying that he will be the one to defeat the Undead. Kenzaki goes into fight anyway. Meanwhile, Hamije watches the two getting dominated by the Undead. He analyses their movements and calls them too slow and questions if this tis all the power that humans really have. The Undead manages to hit Tachibana and knocks him to the ground. Kenzaki fights back and knocks an antler off of the Undead's Head. He scans his Kick Card and kicks the monster destroying it. Hajime realises that a human's power is greatest when it is trying to save someone and He walks off.

Kenzaki uses one of his cards to seal the Undead giving him the Thunder Card. Tachibana cancels his transformation and tries to get away but collapses in the snow. Kenzaki comes to his aid but changes his mind and starts asking him if he was the one who attacked BOARD and kidnapped Chief Karasuma. Tachibana tells him to think what he wants as he wont give him any excuses. Kenzaki demands that he let Karasuma go. He tells Tachibana that he doesn't want to fight but that he is beyond salvation. Kenzaki accuses him of unsealing the Undead and Tachibana starts laughing in denial. He tells Kenzaki that Karasuma and others were responsible for the unsealing. Kenzaki doesn't believe him. Tachibana tells him that the Rider System was created and then the Undead were released so that they could be sealed again. He concludes to Kenzaki that in the end they were simply used by BOARD. Kenzaki asks for proof. Tachibana tells him that his body is proof of it and that after using the Rider System for so long, it will make his body fall apart. After finally telling him to prepare himself for his body becoming like that as well, Tachibana staggers off while Kenzaki falls to his knees, worrying at the aspect of his body falling apart. He has a premonition similar to Tachibana's where he turns green and disappears.

Hajime returns to the Jacaranda to find no-one home. He hears something and runs downstairs to find the two girls being showered in sparkling dust. Haruka questions what it is... It suddenly stops before everything in the room lights in a pink flame. Amane tries to save a photo of her father but Hajime pulls her back before she touches the flame. The Undead responsible for it floats down from the sky outside as Hajime senses it.
