Spoiler scope: the first two television seasons, especially episodes 18, 29 and 38–40. One passage compares the earlier Japanese web novel and labels that version separately. This is a reading of the character’s choices, not a clinical diagnosis or a complete explanation of Return by Death.
Reading the character
Three changes in Subaru’s idea of being a hero
Compare what each kind of support changes without treating one conversation as a cure.
- Encouragement does not erase self-hatredRem’s support helps him act before he has learned to value himself.
- Rescuing everyone has to include SubaruSatella exposes the missing person in his imagined successful future.
- Trust changes how a plan is madeOtto’s help gives another person an active role instead of making them a reward for Subaru’s suffering.
Failure threatens the person Subaru wants to be
The appeal of a repeatable attempt is easy to understand: a mistake need not be the last word. Yet a second chance becomes a trap if Subaru treats every failed outcome as proof that he has no value. He then needs the next rescue to justify the person doing the rescuing. The pressure comes from the meaning he gives failure as well as the immediate danger.
This reading does not require a label such as borderline personality disorder, sociopathy or a diagnosed trauma condition. Those labels appeared too confidently in the earlier article. What we can follow is a pattern of decisions: who Subaru tries to save, what help he rejects, and whether he counts his own survival as part of the result. Those are narrative questions the scenes can answer.
Rem helps him continue before he likes himself
The official episode 18 account places Subaru at another return to the capital, exhausted by his inability to save the people he cares about. The conversation that follows is often treated as a finished cure for his self-loathing. Its more interesting function is to make another attempt possible while leaving that problem unresolved.
Nagatsuki’s web-novel Arc 3, chapter 52, “From Zero” makes the distinction explicit. Rem offers support when Subaru cannot believe in himself, and the narration at the end still describes him as disliking himself. The chapter is an earlier version, not a transcript of the television script. It nevertheless gives us a precise basis for separating borrowed courage from completed self-acceptance.
That separation preserves Rem’s agency. She is responding to the person and choices she knows, rather than confirming everything Subaru says about himself. Her encouragement can challenge his conclusion that he is worthless without pretending that every action he has taken was right. It is possible to reject someone’s account of their failure while taking their pain seriously.
The danger comes when Subaru turns being her hero into a demand he must satisfy at any cost. Support meant to make a future possible can become another test he imposes on himself. The later tea-party chapter returns to precisely that problem. For the relationship question itself, our separate reading of Subaru and Rem in episode 18 examines their different choices; this article follows what accepting support changes in Subaru.
The memory of home interrupts the fantasy of starting over
The first Sanctuary trial brings his old life into the argument. Episode 29, “Parent and Child” returns him to familiar domestic surroundings with Kenichi and Naoko. Its place in the season matters: a new world cannot make the person who entered it disappear. The story pauses an external crisis to put his earlier relationships back in view.
My reading is that this interrupts the idea of the fantasy world as a clean replacement identity. Subaru can learn new skills and make new relationships, but doing so does not mean his former life was worthless. A future built only on becoming an entirely different, impressive person would leave every ordinary failure threatening that future again.
The scene’s family setting also offers a contrast with the rescue plot. A relationship can matter before the person has won a battle or demonstrated special usefulness. That is the question carried forward into the tea party: can Subaru allow himself to be wanted without first paying for it through an exceptional sacrifice?
Satella identifies the missing person in his rescue plan
In the web novel’s Arc 4, chapter 78, Subaru treats repeated attempts, paid for with his own life, as a way to secure everyone else’s future. He returns mentally to Rem’s belief in him. Satella’s objection is that the people he wants to save should include him, and the passage moves toward his recognition that he wants to live in that future too. This is the novel’s wording and narration; the anime counterpart is episode 38.
The important change is in the definition of success. If Subaru survives only in order to become useful again, his life remains a resource. Wanting to share the future gives that life a purpose that does not end when the others are safe. That does not make helping them less serious. It prevents the imagined rescue from depending on the rescuer’s disappearance.
It is also a limit on the heroic identity Rem helped him recover. A person can hear an expression of trust and convert it into an obligation to be inexhaustible. The later scene asks whether Subaru can receive affection without translating it immediately into more work or more suffering. That is a harder development than simply becoming brave enough for another attempt.

Otto turns trust into something Subaru can do
The official summaries for episodes 39 and 40 pair Subaru’s despair at the arranged threats with Otto’s intervention, then show Otto risking himself to buy time. Another person becomes part of the action. The help is not merely a reassuring speech offered before Subaru resumes solving everything privately.
This gives the earlier insight a practical test. Cooperation requires accepting that someone else has knowledge, intentions and risks of their own. Subaru cannot both demand genuine help and control every part of the helper’s role. A shared plan therefore costs him a kind of certainty even as it gives him possibilities his isolated thinking could not produce.
That is why friendship is more than a prize awarded after sufficient pain. If other people only appear as the happy ending Subaru must earn, they have little agency inside the attempt. Otto’s involvement makes a relationship part of the method. The possibility of being supported has to change what Subaru permits another person to do.
The trials are not a complete theory of parallel worlds
The emotional force of the second trial does not settle the cosmology of Return by Death. It makes Subaru confront the possibility and meaning of being mourned. That is different from demonstrating the continued physical existence of every failed world. This article does not use an experience within a trial as an independently established map of the universe.
The Books of the Dead belong to a later part of the story, outside this essay’s spoiler scope. They are not used here as a shortcut to a final verdict on every branching-world theory. The argument about Subaru’s value can be tested against the choices in these scenes without claiming to have solved the power’s remaining mysteries.
Growth remains a change of practice
These scenes form a useful comparison rather than a three-step cure. Rem makes continuing possible, the tea party exposes the cost of excluding himself, and Otto makes accepting help visible in action. None requires us to claim that one conversation permanently removes fear, dependence or the temptation to solve another problem alone.
The distinction is visible whenever we ask two questions separately: did Subaru find a way through the crisis, and did the way he chose allow his own life and other people’s agency to matter? The answers need not coincide. That tension is what gives his development substance beyond the number of deaths he can endure.
For a contrasting relationship in the same series, see our analysis of Ram and Roswaal’s dependence. It asks how practical support, gratitude and responsibility for harm can coexist, rather than treating every reliance on another person as either rescue or weakness.
