What is the plot?

Yuki wakes up in a luxurious black-and-white bedroom inside a windowless Western-style mansion, dressed in a classic maid uniform, with no memory of how she got there. After orienting herself in the room, she leaves and enters a monochrome hallway lined with closed doors, where the strange, staged atmosphere makes it clear this is not an ordinary building. She goes into a dining room and finds five other girls already gathered there, all dressed the same way and all equally confused about how they arrived.

The group begins to piece together that they have been placed into a death game inside the mansion. The setting is filled with lethal traps, and the objective is to escape the building alive. Yuki immediately stands out from the others because she reveals that this is her twenty-eighth game, making her the only participant with significant experience. She explains the basic structure of the game from that experience: there is no visible time limit, the food supply is limited, the players are being recorded, and the prize money differs from person to person. She presents herself as calm and practical, and the others react to her as someone who understands the system far better than they do.

As the situation develops, Yuki continues outlining how these games work and how survival usually depends on cooperation, while also making clear that she is prepared to protect herself first if necessary. The others, most of whom are still in panic or disbelief, have to decide whether to trust her guidance or treat her as another danger inside the mansion. The episode establishes that Yuki's experience is not just background detail but the central reason the group begins to follow her lead at all.

The first major sequence of danger centers on an escape challenge inside the mansion involving a key and a room with traps. As the girls try to progress, the game's structure forces them into a situation where they must keep a key moving or risk being cut down by buzz saws. The pressure creates immediate desperation, and the group's fear turns into frantic competition over survival. The escape mechanics also reveal that this is not a simple puzzle but a lethal timed ordeal in which hesitation can mean mutilation or death.

The game then escalates into a harsher survival problem involving an elevator with a weight limit. At this stage, only a limited number of the girls can continue, so the group is forced to make an impossible decision about who will remain behind and how much of each body can be spared. The girls realize that escaping together is no longer possible for everyone, and they begin to calculate survival in purely physical terms. The situation becomes grotesquely practical, with the participants forced to consider amputations as the only way to reduce weight enough to proceed.

Kinko ultimately makes the decisive sacrifice in this sequence. As the others struggle with the weight-limit problem, she chooses to give up her own body so the remaining survivors can move forward. The resulting mutilation is severe: three of the girls lose a leg, and Kinko is cut down further than the others, with half of her body removed to satisfy the elevator's requirements. The scene makes clear that her sacrifice is not symbolic but a literal physical payment for the others' survival.

Yuki is the one who finishes the game's final violent act. Once the elevator problem is resolved and the group is reduced to the last viable survivors, Yuki kills Kinko by using her crutch against Kinko's face and pushing it through, finishing her off to complete the game. The episode makes clear that this is not done in hesitation or confusion; it is the final step that allows Yuki to survive the round and leave the building's deadly sequence behind.

The episode ends with Yuki having survived her twenty-eighth death game while the mansion's first trap-filled ordeal is concluded, leaving the surviving participants changed by what they were forced to do to escape.

What is the ending?

Yuki is the only main participant who makes it out alive. In the end, she kills Kinko to trigger the final clear condition, then leaves the mansion alone and returns to her apartment.

Scene by scene, the ending unfolds like this: after the earlier killing game and the room reset, the group is left trapped in the mansion with the exit still locked. They search for another way out, but the game forces them into a brutal calculation around the elevator's weight limit. To reduce the load, the girls agree to amputate their legs in a controlled order so they do not attack one another in panic. Each of them loses a leg, and then they continue trimming anything else they can--cutting hair and shortening their maid outfits--to get lighter. Kinko is carried because she has lost both of her legs, and Yuki bears her weight as the group strains to reach the required limit.

When they finally get under the limit, the game reveals its last condition: a third death is needed to clear the stage. Yuki then turns on Kinko. She points her crutch at Kinko's face and drives it forward, killing her and activating the third indicator light. The exit opens immediately after that, and Yuki walks out of the building as the only one who clears the game.

Afterward, Yuki is taken back to her apartment. She checks the time, sets a timer for three minutes, and quietly goes through her post-game routine while thinking about the players who died during the game. Kinko's fate is death at Yuki's hands, while Yuki survives and returns home alone.

Is there a post-credit scene?

There is no clear evidence in the available sources of a separate post-credit scene in Episode 1. The most specific Episode 1 source describes the ending as Yuki clearing the game, returning to her apartment, and performing her post-game routine of silently thinking about the dead players, but it does not mention any extra scene after the credits.

What the source does confirm is that the episode ends on Yuki's aftermath: Kinko is killed during the final stretch of the game, the exit opens, Yuki leaves the building, and then she is transported home and immediately sets a three-minute timer for her routine reflection. A fan discussion also describes the ending as Yuki killing Kinko and "que sera sera" playing over the end, again without indicating a distinct post-credit stinger.

So, based on the available material, the safest answer is: no confirmed post-credit scene is documented for Episode 1.

Is this family friendly?

No, this show is not family-friendly; it is rated TV-MA and is explicitly intended for mature audiences due to its graphic depiction of lethal scenarios and psychological horror.

Potentially objectionable or upsetting aspects for children or sensitive people include:

  • Graphic Violence and Death: The core premise involves "death games" where approximately one-third of participants die in each round, with blood explicitly shown turning into a cotton-like substance upon contact with air .
  • Lethal Traps and Mazes: Scenes feature characters navigating deadly mazes with locked rooms, traps, and escape challenges that result in fatal consequences .
  • Psychological Horror and Mind Games: The show is categorized as horror and psychological, featuring intense mind games, chilling atmospheres, and the desperate prioritization of one's own survival over others .
  • Forced Participation: The narrative includes instances where players are forced to participate in the games rather than volunteering, adding a layer of distress and coercion .
  • Injury and Cybernetics: Characters suffer severe injuries that are either healed or replaced with cybernetics by the organization, which may be visually disturbing .
  • Overall Tone: The series is described as "scary," "chilling," and "visually striking" with a focus on the grim reality of surviving lethal competitions .

Viewers with a low tolerance for graphic violence may find the "preservation treatment" of the blood (turning into cotton) slightly spares them from the most visceral gore, but the overall context of death and lethal traps remains highly intense .
