What is the plot?

The episode opens with Takopi explaining everything to Azuma, but Azuma is unable to understand the complex situation Takopi describes. This sets the stage for the emotional and narrative climax of the story.

Following the emotional collapse from the previous episode, Shizuka runs away to Tokyo, overwhelmed by guilt and loneliness. She is depicted as isolated and struggling with her feelings, which have been building up throughout the series.

Naoki, another central character, confesses his sins and is utterly broken by the consequences of his actions. His confession adds to the heavy emotional atmosphere and highlights the depth of the characters' suffering.

Takopi, witnessing the fallout of his well-meaning but misguided actions, realizes that he must take drastic measures. He decides to use his Happiness Power to reset the entire timeline, not just to undo specific events but to rewrite reality itself. This decision is the pivotal moment of the episode, showing Takopi's willingness to sacrifice himself for the happiness of others.

The timeline reset creates a new reality where everything appears normal and peaceful. Shizuka now has a family, Hina is safe, and Naoki has not spiraled into despair. The past traumas never happened in this version of the world because Takopi was never present in it.

Despite the reset, Shizuka experiences a faint smile and a flicker of sadness as she looks at the sky, suggesting that although she does not remember Takopi, some emotional imprint of his sacrifice remains within her. This subtle detail underscores the bittersweet nature of Takopi's sacrifice.

The episode closes on this note of quiet sacrifice and healing. Takopi is not remembered, nor is he missed, but his choice brings peace and hope to the others. The story ends without resurrection or reunion, emphasizing the selflessness of Takopi's ultimate act of love.

Throughout the episode, the narrative carefully unfolds the themes of healing, selflessness, and forgiveness, culminating in Takopi's unseen sacrifice that allows others to heal themselves. The six-year time jump reveals Shizuka and Marina as best friends, purchasing pens together, symbolizing that trauma does not have to define one's future.

What is the ending?

At the end of Takopi's Original Sin Season 1, Episode 6 "To All of You in 2016," Takopi makes the ultimate sacrifice by using his Happiness Power to reset the entire timeline, erasing himself from existence to undo the traumas suffered by Shizuka, Hina, and Naoki. In the new timeline, the characters live peaceful lives without the dark past, though Shizuka retains a faint, inexplicable feeling of sadness and a vague memory of Takopi despite not remembering him directly.


The episode opens in the aftermath of the previous episode's emotional collapse. Shizuka, overwhelmed by guilt and despair, runs away to Tokyo, isolated and broken. Naoki, similarly shattered, confesses his sins and the weight of his actions. Takopi watches these consequences unfold, realizing that his earlier attempts to fix things have only caused more pain.

Takopi wrestles with the moral burden of his original mission--to kill Shizuka to prevent a tragic future--but now understands that such drastic measures are not the answer. Shizuka confronts Takopi, consumed by anger and despair, demanding a gadget to exact revenge. This confrontation is tense and charged, highlighting the depth of her pain and transformation from innocence to rage.

Naoki and another character, Anogus, intervene, offering Takopi a nuanced perspective on human nature, emphasizing that people are neither purely good nor evil. This conversation takes place against a stark, muted Tokyo backdrop, underscoring the bleakness of the situation and Takopi's role as an unwitting catalyst for hope.

With tearful sincerity, he apologizes to Shizuka, acknowledging his failure to understand her pain fully. The atmosphere is heavy with muted colors and shadows, amplifying the sense of despair and the gravity of his decision.

The climax sees Takopi use the repaired gadget to reset the entire timeline, not just undoing specific events but rewriting reality itself. This act erases Takopi's existence from the world, but it also erases the traumas that plagued Shizuka, Hina, and Naoki. In the new timeline, Shizuka has a family, Hina is safe, and Naoki has not spiraled into despair. The past horrors never occurred because this version of the world never included Takopi.

The final scenes show Shizuka and Marina as friends in this new 2016 timeline, bonded by a faint, inexplicable memory of Takopi. Shizuka looks at the sky with a faint smile tinged with sadness, suggesting that while she does not consciously remember Takopi, his emotional imprint lingers.

  • Shizuka: Lives a peaceful life in the reset timeline with a family, free from the previous pain and guilt, though she feels a subtle, unexplained sadness.
  • Hina: Safe and unharmed in the new timeline, her suffering erased.
  • Naoki: Does not spiral into despair or guilt in the reset timeline, living a stable life.
