Subaru Natsuki steps out of a convenience store and into a fantasy world with no special powers to show for it — except one. Every time he dies, he wakes up at an earlier point in time, carrying the memory of everything that went wrong. Saving the people he cares about means dying again and again until he gets it right.

Follow this list from start to finish — the story builds directly on itself, so there's no reason to shuffle anything around. The OVA entry sits after Season 1 and is worth watching, but you won't miss anything plot-critical if you skip it.
Start here. These 25 episodes introduce Subaru and show how his strange ability works. The first episode drops you straight into the fantasy world with no hand-holding, which is part of the fun.
Two side stories in one entry. Memory Snow is a lighthearted comedy set after Season 1 and works well as a breather. The Frozen Bond is something else entirely — a prequel about how Emilia and Puck first met, years before the main story begins. Neither is required, but the second one adds a lot to a character you've already spent 25 episodes with.
Thirteen episodes picking up directly where Season 1 ends, so don't take a long break between them. Season 2 was split into two parts that aired several months apart — this is the first half, and it sets up a much larger and darker story.
Twelve episodes continuing straight on from Part 1. Treat it as the second half of the same story rather than a separate season and go from one into the other without stopping.
Sixteen episodes carrying the story on from the end of Season 2. All of them have aired, so you can watch this one straight through without waiting.
Season 4 is split into two halves totalling 19 episodes. The first 11 aired between April and June 2026 and are complete. The remaining 8 began airing in August 2026 and are still coming out weekly, so catch up through Season 3 first and then join the ongoing run.
⚠ This season is still airing, so you will reach the latest episode before the story is finished.
Re:ZERO is one of those series where the story never doubles back on itself, so there's no need to rearrange anything. Start with Season 1 and let it run — its 25 episodes do a good job of establishing the world and Subaru's situation before things get complicated.
The OVA entry is the one place where you have a real choice. It collects two very different shorts: Memory Snow, a comedy set just after Season 1, and The Frozen Bond, a prequel about Emilia and Puck meeting long before the main story starts. Neither is required reading for Season 2, but The Frozen Bond in particular adds a great deal to a character you've already spent a whole season with. Watch them before Season 2 if you watch them at all.
Season 2 is listed as two separate entries because it aired in two cours with a gap between them, but it's really one continuous 25-episode story. Watch both parts close together so the momentum doesn't stall. Season 3 follows on naturally, and Season 4 is airing now, split across two halves with the second still coming out weekly.
One thing worth knowing: streaming services also list several recap versions with titles like Chapter 1: A Day in the Capital or Chapter 4: The Sanctuary and the Witch of Greed. These are re-edits of seasons you've already seen, made for viewers catching up before a new season aired. They're not new story, so ignore them and stick to the list above.

Where each part of the anime lines up with the source, so you know where to pick up reading.
Only spin-offs that tie into the main story are listed here — anthologies, fan books and the like are left out.
Season 4 is still airing and is adapting Volumes 21 onward, so Season 3 is the safe anchor point — Volume 21 is where the story goes next after it. The light novel is published in English by Yen Press with matching volume numbers, and around 29 volumes are out as of August 2026 against 44 in Japan, so English readers have plenty of runway. Alongside the main volumes there are separate EX side-story books focused on characters like Wilhelm and Crusch; they're numbered independently and aren't required to follow the main plot. None of the TV episodes are anime-original — the adaptation trims and compresses novel material rather than adding to it, so there is no filler anywhere in the run.
Start with Season 1 from 2016. Its 25 episodes introduce Subaru and his ability, establish the world and set up everything that follows. There is no alternate entry point — the story builds directly on itself from episode one.
No, but The Frozen Bond is worth your time. The OVA entry holds two very different shorts: Memory Snow, a light comedy set after Season 1, and The Frozen Bond, a prequel showing how Emilia and Puck met long before the main story. Neither is required for Season 2, but the prequel adds real weight to a character you'll have spent a full season with.
It aired in two blocks several months apart, so streaming services list them separately. Story-wise it is one unbroken 25-episode arc with no natural stopping point between the halves, so watch them back to back if you can.
Those are re-edited versions of seasons you have already seen, released to help viewers catch up before a new season aired. The Season 1 re-edit repackages the original 25 episodes into 13 hour-long ones. None of them contain a new storyline, so ignore them and follow the seasons in order.
Both are optional and neither affects the main story. The Break Time and Re:PETIT shorts are chibi comedy skits that ran alongside the TV broadcasts. Isekai Quartet is a crossover comedy putting the Re:ZERO cast alongside characters from other series — a separate show entirely rather than part of this timeline.
No. Every TV episode adapts the light novels, with no anime-original episodes in any season. If anything the adaptation trims and compresses novel material rather than padding it out.
Yes. Sean Chiplock voices Subaru, with Kayli Mills as Emilia, Brianna Knickerbocker as Rem and Kira Buckland as Beatrice, and the cast has stayed consistent throughout. Seasons 1 to 3 are fully dubbed, and Season 4's first half launched with a same-day dub — the first time in the series' history the dub kept pace with the Japanese broadcast. The dub for the second half, which started airing in August 2026, had not appeared at the time of writing.
Crunchyroll carries every season across the Americas, Europe, Africa, Oceania, the Middle East, India and Southeast Asia, in both subtitled and dubbed form. Availability varies by country and streaming rights change over time, so check what is listed in your region.
Yes. Season 4 runs 19 episodes across two halves — the Loss Arc's 11 episodes aired from April to June 2026, and the Recapture Arc's remaining 8 began on 12 August 2026 and are still coming out weekly. Everything before it is complete, so you can catch up through Season 3 and then join the ongoing run.
Season 3 ends at the close of Volume 20, so the story continues at Volume 21 — which is also where Season 4 begins, if you would rather read ahead than wait. The English edition from Yen Press matches the Japanese volume numbering and is at around 29 volumes as of August 2026, against 44 in Japan. The separately numbered EX side-story books are optional background rather than part of the main sequence.
Around 31 hours for everything that has aired so far, rising to roughly 34 hours once Season 4 finishes. The two OVAs add about two hours on top if you want them.
