Rachel is saved from an attack by Danny, the man calling himself her doctor, when Zack appears. She asks Zack to kill her, and he agrees as the two of them start to search for a way out of the building.

EP3 - I swear to God.

After arriving at the small room in the back of the reference room, Rachel encounters Eddie, the digger of graves and master of Floor B4. Eddie claims that he knows what happened to Rachel's parents and why she's in this building.

EP4 - A sinner has no right of choice.

The door to Floor B3 opens to reveal a space like a prison cell, enclosed by pure white walls and iron bars. The moment Zack strikes the locked door before them with his scythe, the duo are barraged by machine gun fire.

EP5 - Don't let me kill you just yet.

Rachel finds the key card to get them out of the poison gas room, but Zack handles it too roughly and breaks it. The hourglass announces that their time is up, and a powerful poison gas begins to pour into the room.

EP6 - Zack is the only one who can kill me.

After willingly shooting a dangerous drug into his arm so that they could move forward, Zack begins to grow overwhelmed by the urge to kill. But with the last traces of rationality left in his mind, he tells Rachel, Don't let me kill you just yet...

EP7 - Who are you?

After slashing open his own belly, Zack is left without the strength to stand, so Rachel sets off alone into Floor B2 in search of something to stop his bleeding

Rachel heads to Danny's floor with Gray, the priest, to search for something she can use to treat Zack. However, Gray tells her she must undergo a series of tests to get there.

EP9 - There is no God in this World.

Danny, who Zack thought he killed on Floor B5, shows up and offers Zack a deal: Rachel's eyes in exchange for medicine to treat his wound. Meanwhile, Rachel finds Zack's room on Floor B6 and retrieves the knife he asked for.

EP10 - The witch trial shall start

Carrying Zack's knife, Rachel sets off once more, determined to find Danny and get the medicine she needs to stop Zack's bleeding. But once again, pink smoke carries her away into a world where she can't tell illusion from reality.

EP11 'cause you are my God, Zack.

Gray proclaims himself closer to being a God than anyone else and sentences Rachel to burn alive for the things she did to the other floor masters. Hanging on her cross, Rachel insists that she's not a witch and that she only wants Zack to kill her.

EP12 - Try to know everything about her

Floor B1 looks like an ordinary residence. After following a trail of blood to what appears to be a living room, Rachel suddenly panics. She pressures Zack to kill her immediately, then passes out. Then Danny appears, only to shut Zack out of the room and tell him, If you succeed in learning everything, I'll open the door. So Zack sets off to search the floor on his own for the truth...

EP13 - I'm Not Your God.

Zack continues watching a recording of an interview between Danny and Ray, where Ray reveals that her parents were abusive and hated her and each other. One night, her father finally snapped and stabbed her mother to death, prompting her to take her mother's gun and shoot her father to death. Afterwards, she stitched their bodies together in order to create the perfect family and lived happily with them until the police arrived. Noticing her blank, blue eyes, Danny reveals to Ray that his mother committed suicide due to him having been born missing an eye, and he becomes obsessed with Ray since her eyes resemble his mother's. Angry and disgusted, Zack storms back to where Ray and Danny are and proclaims his suspicions that Ray is in fact the angel of B1, which Danny confirms, and reveals that Ray was sent to B7 after finding newfound faith in God by reading a Bible. Knowing that she lied to him, Zack angrily declares that he is not Ray's God and asks her if she will kill him, as a trespasser on her floor. Ray flees, luring Zack through more traps until he manages to corner her in the last room. He once again asks her if she intends to kill him when Danny arrives and holds him a gunpoint. Cornered by the two of them, Ray then calmly draws her gun and fires.

EP14 - Swear You Will Be Killed by Me.

Ray shoots Danny much to his surprise, claiming that Zack is hers to kill and sew up. However, she remains conflicted since she has lost her faith in her God, meaning there is nobody left to forgive her for her crimes, and hesitates in shooting Zack. Pushing her down, Zack reminds Ray that he made the promise to kill her, not her God, shaking Ray back to her senses. The two swear to each other again on their vow and attempt to continue their way out. Although B1 is Ray's floor, she is unaware of its location even after knowing every nook and cranny of the place, deducing that the exit must be on B2 due to her floor being the last to be built and the strange observation that no one ever came down from above. While on the way to reactivate the elevator, she encounters Gray, with questions her intentions and her identity, telling him that she has accepted herself and will hence take responsibility for her own actions and choices from now on. Satisfied with her answer, Gray gives her a hint that the exit is behind the huge stained glass window of his floor. When Zack and Ray reunite, they try to find her gun as well but realize Danny's body is missing once again and that Ray's gun has been destroyed. Together they warily return to B2, where Zack smashes through the stained glass window to reveal a long flight of stairs leading to the surface. Just then, the building's self-destruct sequence is initiated.

EP15 - A Vow Cannot Be Stolen.

Ray and Zack flee up the stairs as the facility begins to burn and collapse, but their way is blocked by steel bars. Zack briefly has a panic attack due to his fear of fire, but he manages to regain his senses upon seeing Ray struggling to break the bars. Overcoming his fear, Zack manages to break through the bars and all other obstacles, though he breaks his scythe in the process. They finally reach the top floor, where Ray asks Zack if he truly wants to kill her, and she wouldn't fault him if he changed his mind. Zack reaffirms the promise he made when Danny arrives and shoots Ray in the back. He reveals he was the one who activated the self-destruct sequence and holds Zack at gunpoint to watch Ray die, so he will have to live with the knowledge he couldn't fulfill his promise. Ray assures Zack that she doesn't care if their vow is fulfilled or not, only that the vow was made in the first place, and she will carry the burden of their vow so Zack doesn't need to think of himself as a liar. Jealous of Ray's affection for Zack, Danny shoots Ray again and prepares to kill Zack when Gray disables him with a crossbow. Grey orders Zack to leave through the exit, assuring him there is still a chance to save Ray. Zack picks up Ray's body and heads for the door with Danny still pointing his gun at his back.

EP16 - Stop Crying and Smile.

Gray shoots Danny again to prevent him from shooting Zack. As Zack carries Ray through the exit, Gray has a final conversation with Danny, revealing that he became fascinated with how Ray and Zack managed to change each other, and how he's come to realize that everybody is a human, both flawed and beautiful. The building then collapses, presumably killing both Danny and Gray. Zack is able to reach the surface just as the police arrive to investigate the building collapse, surrendering to the police so Ray can be taken to a hospital. After recovering from her wounds, Ray is taken to a mental care facility where the staff attempt to rehabilitate her with limited success. Deemed guilty for his murder spree as well as killing Ray's parents and kidnapping her, Ray is informed that Zack is sentenced to death. However, shortly after hearing the news, Zack breaks into Ray's room to fulfil their oath, having escaped prison. As they both leap out of the window to escape, Ray once again pleads for Zack to kill her, which Zack reaffirms by telling her to stop crying and smile. By the time the police arrive, the room is already empty with a splatter of blood on the windowsill and Zack's knife on the floor.
