Re:ZERO Season 4 Part 2: Does Subaru Read His Own Book of the Dead?

If there is one thing Re:ZERO -Starting Life in Another World- has never been afraid to do, it is make Subaru suffer in ways that feel genuinely personal. Not just physically. Not just emotionally. The series has always been at its best when it forces Subaru to confront the parts of himself he desperately wants to ignore.

And that is exactly why the Books of the Dead storyline in Re:ZERO Season 4 Part 2 hits so hard.

The big question surrounding Subaru and the Taygeta Library is simple: Does Subaru actually read his own Book of the Dead?

The answer is yes. But honestly, saying that Subaru “reads his own book” makes the situation sound far less horrifying than it actually is.

He doesn’t simply open a dusty volume, skim through a few pages, and suddenly remember everything. Subaru is forced to confront the accumulated horror of his own existence. His deaths. His failures. His fear. His despair. The countless moments where he broke down and had no idea how he was supposed to keep moving forward.

For me, this is one of the most fascinating ideas in the entire Re:ZERO story. Return by Death has always been Subaru’s greatest weapon and his greatest curse. But the Books of the Dead take that concept and turn it into something physical. Something he can actually look at.

And that’s terrifying.

What Are the Books of the Dead in Re:ZERO?

The Books of the Dead are connected to the mysterious Taygeta Library, located within the Pleiades Watchtower. These books contain the memories and experiences of people who have died, effectively preserving a record of their lives after death.

Normally, this would already be an unsettling concept. But Subaru’s situation is completely different.

For most people, death is the end of their story. They live once, die once, and leave behind a single record.

Subaru doesn’t have that luxury.

Because of Return by Death, Subaru has died countless times across different loops. His memories remain with him, while the world itself is repeatedly reset around him. The result is a situation that completely breaks the normal rules surrounding the Books of the Dead.

Subaru isn’t just a person with one tragic story.

From the perspective of the Taygeta Library, he has accumulated a horrifying history of death after death.

That is where the concept becomes genuinely disturbing.

Imagine being Subaru and discovering that every time you thought you had escaped a nightmare, the universe had apparently kept the receipts.

The Books of the Dead represent:

• Subaru’s failed timelines and deaths.
• The memories connected to those experiences.
• The psychological trauma he has carried alone.
• The reality of Return by Death viewed from outside his own perspective.
• A record of the person Subaru was before his memories were taken from him.

The last point is especially important.

Because when Subaru encounters these books after losing his memories, he isn’t simply trying to remember his past. He is trying to understand who he was.

And that is a much more complicated question.

Why Amnesiac Subaru Is So Important to This Story

The Subaru we see after losing his memories is fundamentally different from the Subaru fans have spent years following.

He doesn’t remember Emilia.

He doesn’t remember Beatrice.

He doesn’t understand the full nature of Return by Death.

Most importantly, he doesn’t have the emotional context that made those relationships meaningful to him in the first place.

This creates one of the strangest situations in Re:ZERO. Subaru is essentially watching the story of his own life as if it belongs to somebody else.

And, honestly, I think this is where the Books of the Dead become much more interesting than a simple “memory recovery” plot device.

Amnesiac Subaru looks at the person recorded in those books and struggles to understand him.

Who was this guy?

Why did he keep getting back up?

Why did he keep throwing himself into impossible situations?

Why would someone willingly endure that much pain?

The answer is uncomfortable.

Because Subaru was never the fearless hero he imagined himself to be.

He was scared.

He cried.

He panicked.

He made terrible decisions.

He hated himself.

He wanted to run away.

But he kept choosing to move forward anyway.

That distinction is everything.

Subaru Reading His Own Deaths Is More Horrifying Than It Sounds

The idea of reading your own Book of the Dead sounds almost poetic until you remember what Subaru’s life actually contains.

He isn’t reading about some peaceful childhood or a heroic adventure.

He’s confronting the memories of deaths that include some of the most brutal moments in Re:ZERO.

And this is where I think the story really shines.

Subaru has always been the only person who remembers his deaths.

That means everyone else can look at him and say, “You survived.”

But Subaru knows the truth.

He remembers every time he didn’t.

The Books of the Dead give that invisible trauma a physical form.

For once, Subaru is forced to look at his own suffering from the outside.

That is brutal.

The Biggest Twist: Subaru Starts Seeing Himself as Someone Else

One of the most compelling aspects of this storyline is the psychological separation between Amnesiabaru and the Subaru we know.

At first, the amnesiac Subaru can look at his former self almost like a completely different person.

And that makes sense.

From his perspective, the person in those memories is unbelievably courageous. This “other Subaru” apparently endured death after death and continued fighting for people he loved.

Amnesiabaru struggles to understand how he could ever become that person.

This creates a fascinating form of imposter syndrome.

He doesn’t believe he deserves to call himself the same Subaru.

But eventually, that separation begins to collapse.

And that’s the emotional heart of the whole story.

Subaru doesn’t discover that his former self was secretly a perfect hero.

He discovers something much more important.

The Subaru he admired was just as weak as he is.

The difference was that the original Subaru kept going despite being weak.

That realization, in my opinion, is far more powerful than simply getting his memories back.

Return by Death Becomes Something Much Darker

Before this storyline, it can be easy to think of Return by Death as a strange version of a checkpoint system.

Subaru dies.

The timeline resets.

He tries again.

From a gameplay perspective, it almost looks like an infinite retry mechanic.

But the Books of the Dead completely destroy that interpretation.

Every death mattered.

Every failure left a psychological mark.

Every timeline Subaru experienced was part of his personal history, even if nobody else could remember it.

The Books of the Dead make that idea tangible.

That’s why I think this storyline changes the way we should look at Subaru’s ability.

Return by Death isn’t a free reset button. It’s a mountain of trauma that only Subaru is forced to carry.

The fact that his deaths can potentially exist as records makes the ability even more disturbing.

Subaru may be able to escape the consequences of a failed timeline, but he doesn’t truly escape what happened to him.

He remembers.

And now, in the Taygeta Library, he can literally read it.

Does Subaru Fully Recover His Old Identity?

The answer is essentially yes, but the process is far more meaningful than simply flipping a switch and restoring his memories.

Subaru’s journey through the Books of the Dead forces him to reconnect with the person he used to be.

He remembers the people he loves.

He remembers the battles he fought.

He understands the suffering he endured.

Most importantly, he begins to accept that the person who survived all those deaths was still him.

Not a legendary hero.

Not a different person.

Not some supernatural warrior who never felt fear.

Just Natsuki Subaru.

A painfully ordinary teenager who somehow kept finding the strength to stand back up.

That’s why I think the Books of the Dead storyline works so well. It isn’t really about Subaru discovering his past.

It’s about Subaru accepting himself.

Could Someone Else Read Subaru’s Book of the Dead?

This is where things get even more interesting for fans who follow the later light novel material.

The possibility of another character accessing Subaru’s recorded experiences creates an entirely different kind of danger.

Subaru’s biggest secret has always been Return by Death. The Witch of Envy’s restrictions make revealing the ability almost impossible. Subaru can’t simply sit down with Emilia’s camp and explain everything that happened to him.

But a Book of the Dead potentially changes the situation.

If someone else could experience Subaru’s memories directly, they wouldn’t necessarily be hearing Subaru explain Return by Death.

They would be experiencing his reality themselves.

That distinction is massive.

It could reveal things Subaru has spent his entire life being unable to say.

And if you know anything about Re:ZERO, you already know that giving someone access to that kind of information would have enormous consequences.

The idea is absolutely fascinating because Subaru’s greatest burden has always been his isolation. Even when surrounded by friends, he remains the only person who truly knows what he has endured.

The Books of the Dead challenge that isolation.

And that’s potentially much more dangerous than any monster in the Watchtower.

My Take: This Is Subaru’s Most Important Psychological Battle

I’ve seen plenty of discussions about whether the Books of the Dead are among the strongest concepts introduced in the Re:ZERO story, and personally, I think they absolutely belong in that conversation.

Not because they introduce the strongest enemy.

Not because they provide Subaru with some incredible new ability.

But because they attack the one thing Subaru has always struggled to understand: himself.

The Taygeta Library doesn’t just give Subaru information.

It forces him to confront his own identity.

For years, Subaru has judged himself based on his failures. He remembers the deaths, the mistakes, and the moments where he wasn’t strong enough to save everyone.

But when he reads the story of his own life, he starts seeing something different.

He sees a person who was terrified but continued anyway.

A person who failed but tried again.

A person who wanted to give up but still chose to fight.

And that is why the Books of the Dead storyline is so powerful.

Subaru doesn’t become a hero because he stops being afraid.

He becomes stronger because he finally understands that being afraid never made him a failure in the first place.

For me, that’s the real meaning behind Subaru reading his own Book of the Dead.

It’s not just about remembering what happened.

It’s about finally recognizing the person who survived it.

And considering everything Re:ZERO has put Subaru through, I can’t think of a more fitting way for him to reclaim his identity.

Re:ZERO Season 4 Part 2: Julius Juukulius and the Tragic Truth Behind the Book of the Dead Explained

Final Verdict

The Re:ZERO Season 4 Part 2 Books of the Dead storyline is one of those arcs that makes the series feel completely different when you think about it afterward.

Return by Death is no longer just Subaru’s secret weapon.

It is his history.

His trauma.

His burden.

And, ultimately, part of the person he has become.

The Taygeta Library forces Subaru to look at all of it.

And when he finally understands that the frightened, broken version of himself and the “hero” he admired were always the same person, the entire journey takes on a different meaning.

Subaru didn’t survive because he was fearless.

He survived because, somehow, despite everything, he kept choosing to get back up.

That’s what makes the Books of the Dead so unforgettable.

And honestly? In a series packed with witches, Sin Archbishops, ancient mysteries, and world-ending threats, watching Subaru finally face himself might still be the most dangerous battle of them all.
