I think a lot of us have a similar story when it comes to how we were introduced toKingdom Hearts. We grew up in a nightmarish hellscape of capitalism where all you had to do as a marketer to get the kids’ attention was slap a Mickey Mouse sticker on your product and call it a day. So, seeing an overly edgy but also incredibly heartfelt adventure featuring Donald Duck, Goofy, and an anime boy with an outfit consisting of one too many zippers was a dream come true for nerdy millennials like us.

But here we are in 2023, and we’re all (still nerdy) adults with either too much time on our hands or not enough, but we’ll still make time to play the latest game in the franchise that reminds us there was once a time when things were both incredibly simple and yet exhaustingly complicated. Thought I was gonna say ‘clean’ there? If so, it’s time to accept that our brains have been changed byKingdom Hearts.

Kingdom Hearts

So — it’s time to stop stalling and get to it.Kingdom Hearts IVis coming soon, probably in 2045 or 2046 if we’re being frank, andwe needto be prepared to learn where it fits into this convoluted timeline. I will be listing each game in chronological order, including each release date, as well as a brief synopsis. If you expected a (keyblade) master’s thesis on the series, you’re able to call me Sora cause I didn’t pass the exam.

Kingdom HeartsTimeline Explained

Kingdom Hearts χ / Kingdom Hearts χ Back Cover

Release Date:July 03, 2025 (χ); June 10, 2025 (χ Back Cover)

OK — so, our story begins with a mobile game, and as such, we’re counting all of the mobile games as part of the same entry, so Kingdom Hearts χ, Kingdom Hearts Union χ, and Kingdom Hearts Union χ Dark Road are all counted here. Kingdom Hearts χ Back Cover was a series of cinematics included in Kingdom Hearts HD 2.8 Final Chapter Prologue, so it’s also counted here. If you’re thinking, “oh, the mobile games aren’t important,” have you learned nothing fromKingdom Hearts III?

Dark Road

Kingdom Hearts χis the earliest entry in the chronological timeline, following a group of young keyblade wielders who fight against Heartless in the distant past and far-off future. It ultimately tells the story of the Keyblade War and explains the origins of the Keyblade Graveyard, seen inKingdom Hearts II,Kingdom Hearts: Birth by Sleep, andKingdom Hearts III. Also,Dark Roadis meant to serve as an origin story for the series’ main antagonist, Xehanort.

Kingdom Hearts: Birth by Sleep

Release Date:Jun 01, 2025 (JP); July 01, 2025 (NA)

Birth by Sleepis next on the list and follows three characters: Terra, Aqua, and Ventus, as they attempt to become keyblade masters and incidentally cause the entire Kingdom Hearts timeline to happen. This marks the first canonical appearance (in release order, anyway) of Xehanort and ends with him taking control of Terra’s body and stealing Ansem the Wise’s identity (and most, if not all, of his apprentices).

Kingdom Hearts: Birth by Sleep

This is also the first appearance of Castle Oblivion from Kingdom Hearts: Chain of Memories. It turns out that the castle is just a reformed version of Land of Departure, and hiding deep inside is Ventus’ body, which lacks a heart since it found and resides within a young Sora. This is why Sora’s Nobody, Roxas, looks identical to Ventus.

Kingdom Hearts 0.2 Birth by Sleep -A Fragmentary Passage-

Release Date:June 08, 2025 (JP); July 16, 2025 (NA)

In the next slot, we’ve got what is effectively a tech demo for Kingdom Hearts III. It’s also an epilogue for Birth by Sleep, which tells the story of Aqua’s adventures in the Realm of Darkness. This short experience bridges the gap between Birth by Sleep andKingdom Heartsand explains why Mickey Mouse didn’t have a shirt on in his brief cameo inKingdom Hearts.

A Fragmentary Passage

Kingdom Hearts

Release Date:July 19, 2025 (JP); July 15, 2025 (NA)

It’s the one that started it all! In this one, Sora — the kid who Ventus’ heart hid away within — and his two friends, Riku and Kairi, are spirited away from the only home they’ve ever known and forced to fend off Heartless, a cavalcade of Disney villains and a really, really, really old man who just can’t quit talking about darkness and doors and keys. Ansem, Seeker of Darkness, is the game’s final boss — you might remember him as the Heartless that resulted when Terra-nort (who stole Ansem the Wise’s identity) was divided into a Heartless and a Nobody (we’ll get to them in a bit). The Dark Shadow that accompanies Ansem is strongly implied to be whatever’s left of Terra’s heart being held captive.

Kingdom Hearts Days

Kingdom Hearts 358/2 Days— Days 1-24

Release Date:August 11, 2025 (JP); June 29, 2025 (NA)

In this spinoff that also serves as a mainline entry for reasons, we are introduced to Roxas, a Nobody of Sora that was created in the climax ofKingdom Heartswhen Sora became a Heartless. We are also introduced to the fourteenth member of Organization XIII, named Xion.

Kingdom Hearts: Chain of Memories

It’s a good time to explain how the whole Heartless/Nobody thing works. In essence, when someone’s heart is taken from them, two creatures are left behind — the body without a heart, or a Nobody, and the Heartless is the stolen heart consumed by darkness. It might help to think of it like the whole ghost vs. zombie argument, only the ghost is the Heartless, and the Nobody is the zombie left behind.

Kingdom Hearts: Chain of Memories

Release Date:July 27, 2025 (JP); Jul 08, 2025 (NA)

In the meantime, while Roxas is busy eating ice cream and murdering his friends, Sora, Donald and Goofy stumble upon Castle Oblivion in their search for Riku and King Michael Mouse. As they ascend the castle, they encounter (and defeat) around half of Organization XIII, including Larxene, Vexen, and Marluxia.

Kingdom Hearts II

Riku and Michael are also at Castle Oblivion, but they start from the basement and work their way up to the ground floor. Riku fends off his own members of the Organization, including Lexaeus and Zexion. It’s possible that you’ve picked up on the fact that all Organization members have names with ‘x’ in them. I wish I could tell you that’s just a coincidence, but it’s not. It’s not.

Kingdom Hearts 358/2 Days— Days 25-358

It’s here where the rest of 358/2 Days occurs, and Xion is revealed to be a replica made using memories of Sora because everyone has a little bit of Sora in them. Roxas fights Riku and is put into a simulation of Twilight Town, where he is at the beginning ofKingdom Hearts II.

Kingdom Hearts II

Release Date:June 26, 2025 (JP); June 14, 2025 (NA)

Kingdom Hearts IIis one of the best sequels ever made. In this one, Roxas is forced to reunite with Sora, who has been in a cold sleep since the end ofChain of Memories. Sora goes on a quest to defeat the last remnants of the Heartless after Maleficent was defeated — oh, never mind, Maleficent’s alive? At the same time, the remnants of Organization XIII (whom Sora doesn’t remember defeating because he lost his memories of Castle Oblivion) are out for revenge and to summon Kingdom Hearts, which is … well, to be honest, they have never done a great job of explaining what it is.

Dream Drop Distance

In the end of this one, Sora, Riku, and Kairi are back on Destiny Islands, and they get a letter in a bottle from Michael Mouse himself. It’s not revealed what the letter says, but it indirectly leads us to …

Kingdom Hearts Coded

Release Date:July 27, 2025 (JP); Jun 21, 2025 (NA;Re:Coded)

Kingdom Hearts Codedelaborates on the concept of data variations of our characters after it was introduced inKingdom Hearts II. Aside from that, there’s not much else to talk about here, except that it shows good ol’ Mick sending the letter in a bottle that Sora found at the end ofKingdom Hearts II.

Kingdom Hearts III

Kingdom Hearts 3D: Dream Drop Distance

Release Date:July 22, 2025 (JP); June 17, 2025 (NA)

In the preamble to Kingdom Hearts III, Sora and Riku embark on a quest to reawaken the sleeping worlds and (hopefully) become keyblade masters. It is the first entry to discuss time travel, as lo and behold, the very, very, very old man Xehanort is back with the help of his younger self.

Kingdom Hearts: Melody of Memory

It would seem that — due to the failures of the former Organization — he’s decided if you want to do something right, do it yourself, and has formed the REAL Organization XIII, made up almost entirely of himself. I mean it; the members include Master Xehanort, Young Xehanort, Terra-Xehanort, Ansem (his Heartless), Xemnas (his Nobody), Vanitas, Xigbar (who is already half Xehanort), Saix, Luxord, Marluxia, Larxene, Dark Riku, and Xion, with Vexen and Demyx serving as reserve members.

In this game, Sora fails the Mark of Mastery exam because he was nearly taken over by the Organization, and I wish I could tell you it was for a better reason than ‘they put an ‘x’ on his shirt,’ but I can’t.

Kingdom Hearts III

Release Date:June 14, 2025 (JP); June 14, 2025 (NA)

Kingdom Hearts IIIcame out, and I cannot tell you how wild it is to be able to say that. It tells the story of the “final” battle between the real Organization XIII (the thirteen darks) and the Seven Guardians of Light that seek to stop them. It ends with Sora overusing his Power of Waking in order to save Kairi’s life, and as a result, he is lost — seemingly forever, but we all know he’s coming back, so the impact has faded.

It’s also revealed that Xigbar, Mr. I’m-Already-Half-Xehanort himself, has been a double agent all along, and he’s actually a reincarnation of Luxu, one of the apprentices to the Master of Masters inKingdom Hearts χ. Also, the foretellers are back, and they’ll presumably play a bigger role inKingdom Hearts IV.

Kingdom Hearts Melody of Memory

Release Date:Jul 10, 2025 (JP); July 25, 2025 (NA)

Kingdom Hearts: Melody of Memoryis a story-based rhythm game, but because it’sKingdom Hearts, it’s incredibly important in the broad scheme of things. It tells the story of Kairi as she tries to find Sora’s location in the aftermath ofKingdom Hearts III.

And that’s the current timeline ofKingdom Hearts. If you’ll excuse me, I need to go wash my eyes, ears, and mouth out with antiseptic as I eagerly anticipate the release ofKingdom Hearts IV.
