->''"What mattered the most was remembered the least."''
-->-- '''Tagline'''

''Kingdom Hearts: 358/2 Days'' (said as ''Three-Five-Eight Days Over Two'') is the oddly named fourth offering in the ''Franchise/KingdomHearts'' series. It is an {{interquel}}, taking place between ''VideoGame/KingdomHeartsI'' and ''VideoGame/KingdomHeartsII'' and overlapping ''VideoGame/KingdomHeartsChainOfMemories'' at a few points. As the name implies, the game takes place over almost the entire year between ''I'' and ''II''.

A departure for the series, ''358/2 Days'' stars Roxas, Sora's Nobody introduced in ''II'', and his life as part of the unscrupulous Organization XIII. It also introduces Xion, a previously unmentioned 14th member that can also use the Keyblade and has an appearance similar to Kairi, Sora's LoveInterest. Due to game's seeming lack of a central antagonist, it largely focuses on developing Roxas' friendship with Axel and Xion and characterizing the other Organization members.

The game uses the same ActionRPG format as the main games, but modified for the portable format. Rather than simply exploring worlds in one go, Roxas is sent on various missions by the Organization that require frequent visitations, with the plot unfolding as the missions are undertaken. There's also a local multiplayer option that allows up to 4 players to take on missions together as any Organization member (or some {{Secret Character}}s), giving it the largest player cast in the series.

Many of the cutscenes were remade in HD with new voice work for the CompilationRerelease ''Kingdom Hearts HD I.5 [=ReMIX=]'', including several which were previously text-only. However, gameplay is not available.

This would be the last game in the series to feature Wayne Allwine as the voice of Mickey Mouse before Allwine's death in 2009; as well as the final performance of Creator/ChristopherLee as [=DiZ=] before the actor's death in 2015.

Has a LighterAndSofter [[Manga/KingdomHearts358DaysOver2 manga version]].
----
!!This game contains examples of:
* HundredPercentCompletion:
** Completing every mission and every mission 100%, respectively, will earn you [[spoiler:Mickey and Sora]] as Mission Mode characters.
** If you want the Secret Reports, you have to play the challenge (and special challenge) missions sooner or later.
* AdaptationExplanationExtrication: In the ''HD I.5 [=ReMIX=]'', most, if not all, of the missions are summed up in a small text display - a great deal of the Theatre Mode cutscenes take place in Twilight Town or the Castle That Never Was. Thus, various pieces like "last day to work with Xion, gotta get the Keyblade to work" are left to assumption. A sizable amount of context is lost as a result.
* AdvertisedExtra: Mickey Mouse's only story relevance is in one scene, but he is featured on the cover art.
* AllTheWorldsAreAStage: Zant Stage Rush variety. Each form of [[spoiler:Xion]] is fought in a different world: First Form is in the Bizarre Room in Wonderland, Second Form is at the Manor Ruins at Halloween Town, Third Form is in the Lamp Chamber at Agrabah, and the Final Form is at the Clock Tower in Twilight Town.
* ArbitraryMissionRestriction: The player can replay previously-completed missions as "holo-missions," simulations provided by the Organization. After a certain point in the game, an Ordeal Badge appears in most missions that, when collected, gives the player access to one of a set of holo-missions called "challenge missions." The mission can be completed normally, but it also has an optional objective that will earn the player "Challenge Sigils" that can be redeemed for in-game rewards. Challenge missions also impose mandatory restrictions such as raising the level of enemies/putting a {{Cap}} on the player's level, disabling attack magic, disabling healing, and so on. A few missions also have an "Ordeal Blazon" to collect for access to an even harder challenge.
* ArtificialHuman: [[spoiler:Xion is a Replica created by Vexen. She was designed to copy the Keyblade's power (via taking memories from Roxas) so Xemnas could have more direct control over the weapon.]]
* ArtificialStupidity: The "partner" characters have a tendency to run into walls, fall off of ledges, kill-steal (kill-stealing robs you of Heart Points they want you to get), and teleport in front of the player during jumps.
* AutoRevive: The Auto-Life Ability Panel will revive the user once per mission. The Level 1 version revives them with 1/3 of their total HP, the Level 2 version revives them with 2/3 of their total HP, and Level 3 version revives them with full HP.
* AwesomeButImpractical: The Curaga spell creates a small field of energy that will quickly restore the HP of any all ally that stands in it. Its use in combat is limited since you're forced to stay put in the small area to receive the healing, making dodging boss attacks difficult-to-impossible.
* AxCrazy: Sax in berserk mode. Subverted for [[spoiler:Xion in her transformed final boss state. She appears to be this, but she's actually feigning it so that Roxas will destroy her and she can return to Sora.]]
* BecomingTheMask: Reading the Secret Reports reveal that Axel's initial promise of friendship to Roxas was a lie and that he didn't really feel anything toward him. After coming back from the events at Castle Oblivion, he gradually became Roxas's friend for real.
* BittersweetEnding: [[spoiler:Xemnas' plan to get rid of Roxas and stop Sora's reawakening are thwarted when Xion forces Roxas to kill her, but everybody forgets she ever existed since her existence was based off of the memories of someone else.]]
* BonusBoss: The Dustflier is an optional seventh Heartless in a mission near the end in which Roxas has to take out six. It's essentially just a supersized version of a normal enemy, and it spends the battle flying around. Every time it lands on the ground, it sends out a very large shockwave that can inflict one of thirteen status effects, including blinding you, reducing your defense to level one, and keeping you from jumping. The player is warned beforehand that it's one of the strongest Heartless in the game, but it's easy to go in unprepared and be killed within two hits (not exaggerated in the slightest bit) by this monstrosity.
* BossInMookClothing: The game ''warns'' you about a couple of these: "Caution! A powerful enemy is near!" Living Pods are a straighter example, while Invisibles are actually ''harder'' than their boss version, Orcus, mainly by virtue of having a crapton more HP.
* BossRemix: The theme that plays during the last stage of the fight against [[spoiler:Xion]], "Vector to the Heavens", is a remixed combination of [[spoiler:her]] theme, [[spoiler:Kairi's]] theme, and the series' RecurringRiff "Dearly Beloved".
* BossRush: Mission 89 on Day 353 has Roxas going around Twilight Town to take down 6 powerful Heartless: Gigas Shadow, Poison Plant, Stalwart Blade, Orcus, Veil Lizard, and Power Armor. There's also an [[BonusBoss optional fight]] against the draconic Dustflier, the strongest enemy in the game, that appears in front of the Clock Tower once the other 6 have been defeated.
* BraggingRightsReward:
** The Ultima Weapon is an Ability Panel that increases the strength bonus of weaker weapons to +100, making the early game weapons and {{Joke Weapon}}s completely viable options. It can only be obtained by completing every challenge mission, which includes some of the hardest parts of the game due to the number of {{Arbitrary Mission Restriction}}s.
** The Master's Circle accessory grants total immunity to all StandardStatusEffects and has a high Defense value, but also damages the wielder whenever this miss an attack and prevents healing once they hit critically low HP. It can only be obtained by getting every Mission Crown, which requires completing all missions in Mission Mode at least once.
* BrickJoke: A sad version with Roxas and the winner stick. He keeps forgetting to give the stick to Axel as a present, and later decides to wait until he gets a second one so Axel and Xion can both have one. [[spoiler:When he leaves the Organization, the last thing he does is give the winner stick to Axel.]]
* CallForward:
** The concept of summer vacation and going to the beach gets brought up a couple of times. The prologue of ''VideoGame/KingdomHeartsII'' takes place towards the tail end of summer vacation and has Roxas trying to go to the beach with his friends.
** When Axel asks Roxas "What's our boss's name?" to ensure the latter is following what's going on. This same question is used in the prologue of ''Kingdom Hearts II'' when Axel is trying to get Roxas to remember their friendship.
** The door statue of the Thresholder that Sora fights in ''Kingdom Hearts II'' is present in Beast's Castle.
* CameraCentering: Double-pressing the R button while no enemies are around will focus the camera directly behind the player character.
* CameraScrew: The auto camera is finicky, but it won't give you too much trouble except near walls. Unfortunately, when it does, it screws you hard, making two boss fights (Leechgrave and Ruler of the Sky) much more difficult, and making many of the in-game challenges much harder than they should be.
* CaptainObvious: Roxas's first recon mission with Vexen has him pointing out very obvious features of Twilight Town's infrastructure.
-->'''Roxas''': These tiles are different than the others... it's like a road... \\
'''Vexen''': Fascinating... And? \\
'''Roxas''': Um... \\
'''Vexen''': We'll never get anywhere if you just keep stating the obvious.
* ChekhovsLecture: During a visit to Beast's Castle, Xaldin tells Roxas that if a giant Heartless would ever attack, it would come from the bridge. During 50 Mission on Day 171, a giant Heartless does show up and it's fought on the bridge.
* ChestMonster: Some chests contain Heartless known as Cymbal Monkeys and Tricky Monkeys instead of prizes.
* CerebusSyndrome: Starting with this game the series has made liberal use of [[spoiler: PlayerPunch]].
* CloningBlues: [[spoiler:Xion is a Replica designed to absorb Sora's memories through Roxas. Once she finds out, she has an identity crisis and runs away from the Organization.]]
%%* CompetitiveBalance: The mission mode characters tend to fall under this.
* ContinuityLockout: The game assumes players already know what happens in ''VideoGame/KingdomHeartsI'', ''VideoGame/KingdomHeartsChainOfMemories'', and ''VideoGame/KingdomHeartsII'', doing little to fully explain what happened to newcomers bar a tutorial about the nature of the Heartless.
* CopyProtection: Pirated copies won't go past choosing your difficulty.
* CreatureHunterOrganization: Organization XIII spend much of their time hunting down Heartless so they can take the hearts.
* CripplingOverspecialization: Donald has the highest Magic stat out of all characters, but all of his other stats are bottom-of-the-barrel and the limited Magic system makes his bonus pretty moot. The character with the second highest Magic stat, Zexion, can actually deal physical damage with strong combo finishers due to the CriticalHit mechanics and his high Crit% stat.
* CriticalHitClass: Sax in Mission Mode. His natural Crit and Crit% stats are both the highest out of all characters, and many of his weapons supplement these with bonuses. A high leveled Sax with the right equipment can manage to have one out of every three hits be a CriticalHit, and those crits will do enough damage to take off a full HP bar's worth of health.
* DamnYouMuscleMemory: The UsefulNotes/NintendoDS and UsefulNotes/PlayStation2 have identical 4-button layouts (albeit with different labels), but this game's attack and jump buttons have swapped positions from previous titles.
* DeadpanSnarker: Axel makes several snarky comments while teaching Roxas about the basics of the game.
-->'''Axel:''' See, there's this thing about chests. They have stuff in them.\\
'''Roxas:''' So I should open the chest?\\
'''Axel:''' Yes, that is generally what we do.
* DeathIsASlapOnTheWrist: Dying during the story mode places the player right before the fight that killed them, with full health and their magic and items restocked to the level they were prior to entering the room.
* DefectorFromDecadence: Roxas eventually gets so tired of not knowing anything that he ditches the Organization.
* DemotedToExtra:
** Xemnas gets surprisingly little screen time for the leader of the Organization [[spoiler:and the game's main antagonist]].
** Mickey Mouse's only appearance during the story is in one scene that's completely irrelevant to the narrative.
* DifficultyByRegion: The international versions of the game are easier than the original Japanese. Enemies have less HP, Munny is now awarded for beating missions, and some enemies deal less damage.
* DisappearsIntoLight: [[spoiler:When Xion dies, she turns into light and fades away.]]
* {{Dismotivation}}: Demyx is a total slacker who goes as far as bribing Roxas to do his work for him, because he's "not cut out" for fighting.
* DoomedByCanon: [[spoiler:Xion is never seen or mentioned in ''Kingdom Hearts II'' despite her important role in Roxas's life with Organization XIII. Roxas has no flashbacks involving Xion, so that hints at Xion being Ret Gone. Explained in-game that as Xion's essence was reabsorbed into Roxas, there was nothing left to remember Xion with. Unlike Roxas and Namin, she utterly ceases to exist.]]
%%* TheDragon: Axel to Sax.
* DragonWithAnAgenda: [[spoiler:Sax and Axel are revealed to have formed a plan to overthrow Xemnas, before Sax [[BecomingTheMask became the mask]]. However, unlike [[TheStarscream Marluxia]], who wants to overthrow Xemnas to take over the Organization, Sax and Axel sought to overthrow Xemnas to reclaim their hearts. That and the fact that Xemnas really wanted to use Kingdom Hearts's power to [[AGodAmI become a god-like being...]]]]
%%* DubNameChange: Tons and tons. The problem is, a few cases make for an InconsistentDub.
* DummiedOut: Profile sprites for ''Disney/{{Pinocchio}}'' characters, Megara, Hades, and Tinker Bell exist in the game files.
** Roxas, Axel, Xion, and Marluxia have slightly different [=HUD=] sprites that went unused.
** An enemy called Crooked Chariot was planned to appear in the game (possibly in [[Disney/{{Hercules}} Olympus Coliseum]], judging from its pegasus-like appearance). Its model can still be found buried in the data.
** There are a couple of Keyblades that have unused {{palette swap}}s, such as the Leviathan's counterpart (known as the [[http://www.khwiki.com/File:Windmaker_(Removed)_KHD.png Wind Maker]]).
* DyingAsYourself: [[spoiler:Xion transforms into... some kind of creature (presumably her true form with Sora's combat abilities) in the final battle with her, but returns to normal as she fades away.]]
* EasingIntoTheAdventure: The first 20+ days.
* EarlyBirdCameo:
** [[spoiler:Xion transforms into Ventus once.]] The same cutscene also shows that [[spoiler:Xigbar knew Ventus.]]
** A weirder, smaller, kinda-sorta example: [[spoiler:at one point, Sax calls Axel "Lea", clarifying Axel's original name just in time for Lea's appearance in ''Birth by Sleep''.]]
* EenieMeenieMinyMoai: Lexaeus's "Mystery Gear" joke weapon.
* EffortlessAchievement: The HD version gives you 6 trophies, including 3 golds for doing nothing except watching cutscenes and reading reports.
* FailsafeFailure: [[spoiler: Xion was created as a failsafe, in case Sora and Roxas were unable to fulfill their roles in the Organization's plans. However things don't go as expected when Xion discovers the truth about her existence and rebels.]]
* FakeDifficulty: Any UnexpectedGameplayChange segment -- the controls are set up for an action RPG, not faux stealth segments. Fortunately, it's the ''only'' part.
* FightingYourFriend:
** Roxas fights Xigbar in the Olympus Coliseum about halfway through the game, though it's a friendly match for the games meant to maintain a charade.
** [[spoiler:Xion and Axel face off twice during the game. Both times it's sparked by Axel needing to bring her back to the Organization against her will.]]
** [[spoiler:On Day 352, Roxas and Xion are tricked into fighting each other without realizing it (they think the other is a Heartless due to an illusion) as part of Xemnas' plan, though they're quickly stopped by Axel. They fight again on Day 357, though this time Xion is forcing Roxas into it to get him to destroy her.]]
* FramingDevice: The whole game is Roxas recalling the year on one of the last days (day 357?), before it all went down. He narrates between each major event and an image of him sitting forlorn on the tower with his head drooped accompanies it.
* {{Foreshadowing}}:
** [[spoiler:Xigbar nicknames Xion "Poppet" early on. His pseudo-lampshading ("What? Are you jealous because Poppet got the best nickname?") is practically HarsherInHindsight.]]
** [[spoiler:"Poppet" in and of itself just means she's a pretty young thing. It, as well as the Japanese equivalent, "puu-chan", are both derived from the French word "poupee", which means puppet.]]
** [[spoiler:Xigbar also says, "Ain't Xion just a peach now? The face of an angel. Just gotta be careful -- girls her age have many faces." It can be taken as Xigbar knowing she's living off Roxas's energy, but since Xion is a SequentialBoss...]] It may also foreshadow the fact that [[spoiler:Xion is seen differently by different people. Xigbar knows this, as he sees her as Ventus.]]
** [[spoiler:Xion's multi-faced nature is hinted at throughout the game in a ''very'' subtle way. Within any given cutscene, her hood will randomly appear as up or down depending on who's speaking, with only a camera angle change to disguise the sudden transition. It's easy to mistake this for a bug if you don't already know.]]
** There's also some mild foreshadowing to ''Birth by Sleep'', because Tinker Bell is actually pretty nice to Roxas and seems to be trying to get his attention. How does this fit? [[spoiler:She knew Ventus, the Roxas lookalike, in ''Birth by Sleep'' and probably thinks Roxas is Ven! She was probably trying to tell him to rejoin the Lost Boys.]]
* GenderBender: Believe it or not, [[spoiler:Xion is an incomplete Roxas clone created from Sora's memories. She's female because Kairi's face and personality are Sora's strongest memories, but near the end of the game, with Sora's memories nearly reconstructed by that point, she ends up looking exactly like him just before going OneWingedAngel on Roxas (where "she" looks pretty much like a fully armored Sora with an echoing female voice).]]
* GetBackHereBoss:
** Multiple fights with the Emerald Serenade, which just flies around, out of reach, never attacking. Subverted in all but one such fight, as it speeds up as it takes damage and forces you to ambush it (the game even warns you that chasing it is "an exercise in futility").
** Ditto with "The Stranger" in Twilight Town, except it's played straight.
** The boss fight with Ruler of the Sky, which mostly acts like the Emerald Serenade until it TurnsRed.
** Inverted in mission mode as "Get Away From Me Boss" when playing as Xigbar, Zexion, or Vexen, since they're long-range (by virtue of their weapon for Xigbar, and magic orientation for the other two).
* GettingCrapPastTheRadar: Two examples, both revolving around [[DarkActionGirl Larxene]].
-->'''Larxene:''' What are you looking at? ...Oh, dream on. It's not gonna happen, pipsqueak.\\
'''Demyx:''' [[WitchWithACapitalB Man, why's Larxene gotta be such a witch?]]
* GiveMeYourInventoryItem: The other Organization members in the Gray Area sometimes ask you for a specific common panel. If you hand one over, they'll give you a different panel in exchange. Whether this is worthwhile varies, as the panels they give you are also common drops, and they never tell you what you're trading for beforehand.
* GlassCannon: The "Extreme" accessory allows you to turn Roxas (or any character in mission mode) into one. "Extreme" sets your HPToOne, giving you unlimited use of your LimitBreak, but causing you to [[OneHitPointWonder die from a single hit]] (or two, if you have Auto-Life installed).
* GoingThroughTheMotions: Among other examples, the "sea salt trio" all have very particular ways of sitting down at the clock tower whenever they meet there.
* GoMadFromTheRevelation: [[ZigZaggingTrope Zigzagged]]. [[spoiler:Xion initially resists such a proposition despite the pain she feels, until Xemnas interferes in an attempt to force her to absorb Roxas. Not that he actually succeeded -- she's only [[ObfuscatingInsanity feigning insanity]] because she needed Roxas to destroy her artificial body so she could return to Sora, where she (quite lucidly) decided that she belonged.]]
* GoOutWithASmile: [[spoiler:Xion.]]
* GratuitousFrench:
** All of Larxene's knives have French names. [[KeepItForeign Except in the French version]], where they instead have [[GratuitousGerman German names]].
** Xion's theme is officially called "Musique pour la tristesse de Xion," which means 'music for Xion's sadness'.
* GridInventory: The panel system.
* GuestStarPartyMember: Some missions have Roxas team up with the other Oragnization members to help complete the objective. Each member except for Xemnas and Sax joins him at least once.
* HeadsIWinTailsYouLose: Due to Roxas being DoomedByCanon, the absolute final battle [[spoiler:against Riku]] is this.
* HowWeGotHere: The game begins on Day 255, with Roxas and Axel on the clock tower. Then the game goes back to Day 7 to start the tutorial, showing the friendship of Roxas, Axel and Xion as the story moves on. Once you get to Day 255 again, things steadily go downhill.
* IKnowYourTrueName: Sax pulls this on Axel as a not-so-subtle reminder of where the latter's loyalties ought to lie.
* ImmuneToFlinching: All 4 forms of [[spoiler:Xion]] cannot be stunned at all regardless of how much you hit her. Even when you interrupted her heal, she doesn't even react to being hit, instead she just flew down and continue the fight.
* ImprobablePowerDiscrepancy: A certain challenge mission increases the levels of enemies by '''60'''.
* ImprobableWeaponUser: Equipping the Mystery and Casual Gears give the Organization XIII members bizarre items to use as weapons, such as a huge sandwich for Zexion or a banana for Sax.
* InfinityPlusOneSword: Well, it depends on the character which one is better, but equipping the Pandora Gear+, Omega Gear+, or the Zero Gear will result in one of these for each character. Notably, those three are the only gears that actually change the weapons given to the non-Organization characters. For Roxas, the Zero Gear can even change his fighting style entirely.
* InstrumentOfMurder: Equipping Xigbar with the Mystery Gear makes him wield a pair of trumpets in the stead of his Arrowguns. They shoot musical notes, accompanied by the appropriate sound effects.
* InventoryManagementPuzzle: A far more literal interpretation of the "puzzle" aspect. Roxas's inventory, leveling system, skills, and equipment are represented by "panels" which are slotted into a grid. Some things take up more space than others, and in various shapes. You'll need a keen eye to assemble everything efficiently.
* JackOfAllStats:
** Roxas, Xion, and Sora have an average 5/10 in every stat. This makes them the most versatile characters due to the minor stat customization given by the Panel System, but far from the strongest or most specialized.
** Axel has his stats ranging from a slightly below-average 4/10 to a slightly above-average 6/10, while his chakrams give him both decent ranged and melee options without specializing in either. This gives him a good amount of flexibility without being dedicated to one style.
* {{Jerkass}}:
** Sax is just downright cruel to poor Xion. [[spoiler:It makes the near-endgame boss fight with him rather cathartic.]]
** Vexen flat-out calls Roxas an idiot to his face and spends most of his tutorial with Roxas insulting the kid's intelligence, even though Roxas's spaciness isn't really his fault.
** For the Limit Break tutorial, Lexaeus demonstrates the optimal health amount by punching Roxas in the face.
** Larxene. Every time you go on a mission with her, she gripes about being a babysitter. She does so in her [[spoiler:only Secret Report, too.]] Jerkass she may be, [[LaughablyEvil some of her dialogue is funny]], given that they're not allowed to swear. And to her credit, her last interaction with Roxas is [[PetTheDog surprisingly nice, by her standards anyway.]]
* JokeItem: Equipping the Mystery or Casual Gears will give an Organization XIII members a silly weapon will weak stats. For example, Zexion gets a huge bologna sandwich and Sax will wield a giant banana.
* JustifiedTutorial: Roxas is a newly-born Nobody, and new to the Organization. Since he knows nothing, his fellow members have to inform him about the nature of the Heartless and how to fight.
* KneelBeforeZod: [[spoiler:Sax]] will occasionally yell "Grovel before me!" at Roxas during his BossBattle.
* LastRequest: [[spoiler:As Xion lays dying in Roxas' arms after their fight at the end of the game, she asks him to "set Kingdom Hearts free" from Organization XIII.]] He fails due to being captured by Riku on the way over to the Organization's castle, though it's implied that she knew that would happen and made the request as a trap.
* LateArrivalSpoiler:
** Roxas is a Nobody. This is a massive twist in ''VideoGame/KingdomHeartsII'' that the game tells you within a couple of minutes.
** The only Organization member to return from the Castle Oblivion mission is Axel.
* {{Leitmotif}}: Roxas and Xion each get one of their own. There's also a theme that plays whenever Axel, Roxas, and Xion eat ice cream after missions; a different arrangement of it shows up in ''Birth by Sleep'' when Ven and Lea meet in Radiant Garden.
* LethalJokeWeapon: The various {{Joke Weapon}}s become viable options when equipped with the [[BraggingRightsReward Ultima Weapon panel]], as it increases their damage output dramatically.
* LetsYouAndHimFight: [[spoiler:The Organization tries to get rid of either Roxas or Xion by pitting them against each other.]]
** In the games at Olympus Coliseum, [[spoiler:Xigbar]] shows up as a surprise boss. You're expected to fight him seriously and he doesn't disappoint, but after about a minute or so, TheUsualAdversaries interrupt.
* LevelDrain:
** A standard status ailment.
** Fairly late in the game there's a mission where Roxas's level is halved because he's having an "off day". [[spoiler:This is justified when you learn later that Xion had drained a lot of Roxas's power at that point.]]
* LimitBreak: If a character's HP bar gets low enough so the green part is gone and the orange part is all that's visible, holding down the attack button will activate their ultimate move. They can use it for a period of time relative to how much HP is left (less HP means more time), and equipping the Final Limit panel will double that duration while upgrading the attack during the second half. Each character has their own unique move (except for Roxas and Xion, who share theirs), with some requiring spamming the A button, others requiring precise timing when pressing it, and a couple not requiring the attack button at all.
* LipLock: A pretty bad case of it, but it thankfully doesn't come up too often due to text-box dialogue using character portraits. The ''HD I.5 [=ReMIX=]'' theater mode, however, gets hit with this one ''hard'', with gameplay models being generated for a series of cutscene ''with no gameplay''.
* LongSongShortScene: "Vector to the Heavens" is quickly tossed into the cutscene preceding the final battle with [[spoiler:Xion]] in the ''HD I.5 [=ReMIX=]'' cutscene movie instead of having no music like the original game. Since the movie does not recreate any of the in-game fight scenes, the decently long battle theme is only heard for about 40 seconds before it's cut out by the switch to [[spoiler:Xion's death scene]].
* LossOfIdentity: Roxas.
* LostInTranslation:
** Unless you happen to know Japanese or know enough about culture, Xion being pronounced "Shion" will probably mean absolutely ''nothing'' to you. [[spoiler:Shion is actually the name of a plant associated with memories in Japan.]]
** Axel's speech about why the sun sets red at the beginning. [[spoiler:Roxas spends a lot of time wondering who the "boy in red" is. And the Japanese word for sky? Sora.]]
* LowLevelRun: Levels, like everything else, are panels, and thus if you don't equip any, you're reduced to level 1.
* MadeOfIron:
** In the LimitBreak tutorial, Lexaeus cuts Roxas's HP down by hitting him square in the face. Lexaues is the physically strongest member of the Organization, and ''[[VideoGame/KingdomHeartsChainOfMemories Chain of Memories]]'' shows him being able to shatter boulders with his fists.
** During a mission in Halloween Town, Roxas takes three exploding pumpkins to the face with no adverse effects. These Pumpkins are later shown to be able to blast holes in a stone wall.
* MagicKnight: Xemnas is the best example due to his strength and magic both being near the max, when other specialists have one field with all other stats really low.
* MarathonBoss:
** The fight against Leechgrave takes a significant amount of time, as it's only safe to attack for a short period after its Tentaclaws have been destroyed.
** The Ruler of the Sky is fought while airborne in a huge area, and at some points requires Roxas to [[GetBackHereBoss chase it down]] to hit it.
** The BonusBoss Dustflier has nine and a half health bars and a ton of defense. You spend quite a bit of time running around dodging its near one-shot attacks.
* MeaningfulName:
** Xion's name was liked by Nomura because of its many meanings:
*** ''Shio'' (tide), which connects her to Kairi and Namin.
*** ''Shion'', which is a flower given to someone to mean "remembrance". [[spoiler:Which is [[RetGone tragically ironic]].]]
*** [[spoiler:Her original name, No. ''i'': In mathematics, ''i'' is used to denote the square root of negative one and is often referred to as an "imaginary number".]]
*** [[spoiler:Lowercase Roman Numerals, like i, used to denote subsections or footnotes underneath the capital ones.]]
*** [[spoiler:Roman numeral I is one... No I... No one...]]
* MechanicallyUnusualClass: Xigbar has an ammo counter that determines how many shots he can take before he needs to reload his clips, with the exact number of shots varying between Gears. If he's in the middle of a combo and runs out of ammo, he will continue to attack without firing any shots.
* MindScrew: Indeed it is.
** The existence of the protagonists themselves is based upon a vaguely defined concept of Nothingness, which is anomalous and shouldn't exist, and the plot revolves around rectifying this.
** Most of your main playthrough of the game is told from Roxas's POV. Unfortunately, Roxas is ridiculously, [[{{Egregious}} egregiously]] left out of the loop.
** The Snarl of Memories cutscene.
* MultiplayerDifficultySpike: The game has the Mission Mode, which has a multi-player option. The enemies have buffed stats compared to story mode whether you have multiple players or not.
* MyFriendsAndZoidberg: Non-comedic version. [[spoiler:'Count the chairs. When have we ever been more than thirteen?']]
* ObstructiveCodeOfConduct: The Organization is better about following their Prime Directive than Sora and co. are. 1: Do not reveal the Organization. 2: Remain out of sight of natives. 3: The mission comes before everything. Roxas eventually violates the Directive about the third time [[Disney/PeterPan Tinker Bell]] needs his help.
* OffscreenTeleportation: Zig-zagged. There are a few times where you can see your ally appearing right behind you despite stopping to kill a heartless or getting stuck on something. However, there are other occasions in which you can see them teleport right next to you. [[AcceptableBreaksFromReality Helps keep them from getting stuck on an obstacle.]]
* OneExtraMember: Xion is the the fourteenth member of Organization XIII. [[spoiler:She isn't actually a member or a Nobody, just a Replica designed to absorb Sora's memories. By the end of the game, she was RetGone'd from everyone's memories]].
* OneHitPointWonder: The Extreme accessory will reducer the wearer's max HP to one, though it also allows them to spam {{Limit Break}}s indefinitely.
%%* OneWingedAngel: As expected for Squeenix final bosses at this point. [[spoiler:Xion]] is a good example.
* PetTheDog:
** Larxene is a huge {{Jerkass}} and a sadist, but her last interaction with Roxas involves her almost nearly giving him compliment.
** Vexen's tutorial mission gives him a more teacherly role than most other members and portrays his [[SurroundedByIdiots attitude]] somewhat sympathetically.
* PoisonousFriend: Axel becomes obsessed with keeping Roxas and Xion "safely" in the Organization... whether they like it or not.
* PoorCommunicationKills: Roxas leaves the Organization because no one is willing to tell him who Sora is, where he comes from, and why he can wield the Keyblade.
* PostFinalBoss: [[spoiler:The "real" final boss is Xion, whose destruction is the emotional climax of the narrative. The fight with Riku afterwards is significantly easier and shorter, and is more of a formality to lead the game's ending into the prologue of ''Kingdom Hearts II''.]]
* PowerTrio: Roxas, Xion and Axel.
* PreviousPlayerCharacterCameo: Sora is mentioned multiple times throughout the game. And when you fight [[spoiler:her, Xion calls on Sora's memories to power herself up.]] But Sora himself is only seen through instances of dj vu Roxas feels as he visits the different worlds. The bottom screen shows Sora in the same pose Roxas is in through a haze of static.
%%* PunchClockVillain: Demyx and Luxord are portrayed this way. [[ObfuscatingStupidity Xigbar]] is debatable.
* RageAgainstTheMentor: [[spoiler:Roxas isn't happy when he learns Axel had been keeping the truth about Xion from him.]] "Didn't have it memorized, huh?"
%%* RedOniBlueOni: Axel and Sax, respectively.
* RegionalBonus: Interestingly enough, ''Days'' has a feature in America it doesn't in Japan: In Japan, you ''must'' play Mission Mode with other people in order to get the reward, but in America, you can earn the Mission Crowns in Solo Mission Mode. You also get a varying greater-than-normal amount of them the first time you beat the mission, ranging from 3-4 with normal "kill stuff and report back" missions to 8-10 for major bosses.
* ResignationsNotAccepted: TropeNamer. Towards the end of the game, Roxas decides he's done with Organization XIII and decides to leave. The Organization still needs him, so Dusks, Samurai, and eventually Sax show up to prevent his departure by force.
-->'''Sax:''' We don't accept resignations.
* RetGone: [[spoiler:Once Xion is destroyed, everybody who knew about her forget she ever existed because. The reason this happens is explained as her existence being based off of Sora's memories, so once she's gone the memories will go back to him and any trace of her will disappear.]]
* RoaringRampageOfRevenge: In the end of the game, [[spoiler:Roxas]] goes on a pretty heated one, with his goal being no less than the total destruction of the Organization and the release of all the hearts in Kingdom Hearts. [[spoiler:Riku]] takes him out before he can even get back to the castle, though.
* RunningGag: [[Disney/{{Aladdin}} Agrabah]] has a ''lot'' of sand.
* SadBattleMusic: [[spoiler:Xion's fight theme, "Vector to the Heavens".]]
* SailorEarth: A ''canon'' example. Secret reports reveal that Xion's name comes from [[spoiler:her Organization number, No. i. As in the ''[[MeaningfulName imaginary]]'' number.]]
* SecretCharacter: Characters other than the core members of Organization XIII can be unlocked for Mission Mode.
** Progressing through the game automatically unlocks Xion, Riku, Donald, and Goofy over time.
** King Mickey can be unlocked by completing every story mission and purchasing "The King's Return" from the Moogle shop.
** Sora can be unlocked by completing every story mission 100% and purchasing "Sora's Awakening" from the Moogle shop.
** To play as DualWielding Roxas, equip him with the Zero Gear with 3 Ability Units.
* SequentialBoss: [[spoiler:Xion]], who has four different forms.
* SheFu: Larxene.
* ShipperOnDeck: Xigbar teases Roxas about his relationship with Xion, at one point telling him that "No girl wants a guy who's weaker than her". [[spoiler:It's heavily implied that Xigbar was just screwing with Roxas, as he knew Xion's true nature as a Replica from the start and she looks like Ventus to him.]]
* ShipTease: The Roxas/Xion subtext is paper-thin, and the subtext between the two of them and Axel isn't much better. Xion herself says she loves them in one of the reports, and while Axel's feelings are a bit more complex, Roxas' friendship with Xion is about as close to love as a Nobody can get. One of their mutual Keyblades is even named after a poem dedicated to parting lovers.
* ShootTheShaggyDog: [[spoiler:The protagonists can never accomplish ''anything'', or else the BigBad wins and the universe ends. Ouch.]]
%% ShoutOut isn't Trivia. Don't go misplacing it in the Trivia tab.
* ShoutOut:
** If Luxord has the Casual Gear equipped, he wields a "deck" of CD(-ROM?)s called (at least in the English versions) "Finest Fantasy 13". [[VideoGame/FinalFantasyXIII Take a wild guess what the name sounds like?...]]
** One of Demyx's {{Joke Weapon}}s is a giant tennis racket. Its name? [[Manga/ThePrinceOfTennis Prince of Awesome]]. Which might also be a ShoutOut to WebAnimation/AwesomeSeries (one of which was actually called "Prince of Awesome"). Which, if true, is definitely... awesome. (Note that the weapon is called Prince Custom in the Japanese version, so this would entirely be a ShoutOut on the part of the translators if it were true.)
** More Demyx: his Ultimate Gear weapon is called [[Film/ThisIsSpinalTap "Up to Eleven"]].
** Roxas has a weapon called "Total Eclipse," a possible reference to the Bonnie Tyler song "Total Eclipse of the Heart."
** Lexaeus has a weapon called "[[Literature/{{Discworld}} Octiron]]."
** The ring that offers 100% illusion resistance is called "Lose Your Illusion", probable shoutout to the Music/GunsNRoses double album ''Use Your Illusion''.
* SmashingSurvival: The Hover Ghost's special attack quickly drains your health unless you mash a bunch of keys to escape.
* SoundtrackDissonance: [[spoiler:Xion]]'s final battle theme -- in stark contrast to the epic orchestral OminousLatinChanting-packed themes of the previous game, this one is a melancholy piano-heavy BossRemix of [[spoiler:her theme]] that truly emphasizes the tragedy of the circumstances.
* SprintShoes: The "Haste" ability.
* StandardStatusEffects: ''358/2 Days'' introduces a number of these, including very standard ones like Blinded and Silenced, as well as some unorthodox ones like [[FireIceLightning Ignited, Frozen, Shocked]], Air-Tossed, "Shoe-Glued", and Rewound Defense (sets defense to what it was at Level 1).
* TheStarscream: Sax and Axel planned to betray the Organization, sending nearly half of them to Castle Oblivion so they could be killed by Axel and/or Sora and seeking the Chamber of Awakening in the Castle to find out what Xemnas is up to. They don't go through with it due to the rift that forms between them and Axel's lack of interest after becoming friends with Roxas and Xion.
* {{Tagline}}: "What mattered the most was remembered the least."
* ATasteOfPower: Odd example at the ''end'' of the game: [[spoiler:Day 358 is Deep Dive; you'll play as Roxas dual-wielding Oathkeeper and Oblivion, capable of killing Neoshadows in one hit.]] With the right panel configuration, you can use him in Mission Mode, though not with quite the same level of strength.
* ThankingTheViewer: The credits give a specific mention, along the lines 'to all Kingdom Hearts fans'.
* TitleThemeDrop: During the battle with [[spoiler:Xion]]'s final form.
* TomeOfEldritchLore: Judging from their titles, ''all'' of Zexion's lexicons apart from his joke weapons, which consist of a sandwich and what sounds like a SecretDiary but turns out to be a laptop computer.
* TookALevelInJerkass:
** Sax. He was never the nicest guy around in ''Kingdom Hearts II'', but he's just plain brutal here.
** This applies to pretty much everyone (especially Xaldin) with the exceptions of Luxord, who is the most [[AffablyEvil polite]] member of the group, and Marluxia and Larxene, who aren't ''quite'' as nasty as they were in ''Chain of Memories'' ([[DemotedToExtra but then, they didn't have]] ''[[ForegoneConclusion time]]'' [[TheyWastedAPerfectlyGoodPlot to be.]])
** Zexion isn't exactly mean, he just falls into the category of a harsh teacher. He only insults Roxas once when Roxas suggests returning to the castle instead of going beyond the quota he was given.
* TrademarkFavoriteFood: Taken to an almost ridiculous degree where roughly 30% of the cutscenes will involve watching 1-3 people sitting at the top of a clock tower and eating ice-cream.
** AuthorAppeal, apparently.
* TragicMonster: [[spoiler:Xion at the end of the game, depending on your interpretation.]]
* TraumaCongaLine: Xion and Roxas both get their turns.
* {{Troll}}: Xigbar knows everything about what's really going on but doesn't have a lot to actually do, so he spends most of his time screwing with other members of the Organization. He teases Roxas about his relationship with Xion [[spoiler:knowing that she's his/Sora's Replica that is likely to eventually kill him]], and baits Sax with vague comments about Xemnas's own dark secrets.
* VancianMagic: The panel system works this way. You can only use whatever spells/items you have loaded when you accept a mission (you can pick up more items, but there's a limit to Backpack space).
* VillainProtagonist: Played with. Org. XIII are the villains of the series, but you're playing as their TokenGoodTeammate.
* VillainsOutShopping:
** So much in this game. Demyx spends his time writing songs, Luxord organizes the poker league, and the others like to lounge around in the couches in the Grey Area.
** The manga also provides a panel of Xaldin, Demyx, and Zexion playing [[http://kh13.com/zenphoto/manga/358-2-days/preview/05.png.php Twister]].
** The manga actually has this in ''spades.'' Even members of an evil organization are not immune to the effects of [[http://kh13.com/zenphoto/manga/358-2-days/chapter-11/001.png.php boring monologues]] by their superiors, it seems.
* VisibleSilence
* VoiceGrunting: There are a couple of totally voiced cutscenes, however.
* {{WAFF}}: Most of the game, until the WhamEpisode.
* WatchingTheSunset: Quite a number of the cutscenes involve this. Well, it ''looks'' like this anyway. They're in Twilight Town, which is eternally in those few minutes between day and night, and as such the sun technically isn't setting per se. Just eternally really low on the horizon.
* WeirdnessCensor: Twilight Town appears to be a ghost town whenever you visit. In fact, [[spoiler: Xion, in her AttackOfThe50FootWhatever form, doesn't attract anyone's attention and she's not only in front of the train station, but is in ''broad daylight''.]]
* WhamEpisode: Once [[spoiler:Xion's]] role in the story is revealed, everything gets much darker.
** WhamShot: Xion removing her hood in front of Roxas to reveal [[spoiler: ''Sora's face''.]]
* WhatIsThisThingYouCallLove: Just one of the many emotions Roxas sees (and doesn't understand) in the Disney Characters throughout the game.
* WhatMeasureIsANonHuman:
** Sax falls squarely into this trope with his treatment of Xion, for reasons better left unspoiled.
** So does [=DiZ=], though that was true in the second full title as well.
* WitchWithACapitalB: Demyx on Larxene.
* WolverinePublicity: Mickey Mouse is very prominent on the cover, yet only shows up in one scene that's not even relevant to the story.
* WordSaladTitle: It sounds like one, especially to those who haven't played it. It's so named because the plot describes the events that happened during Roxas's 358 days in the Organization with those days shared by two people.
* YouHaveOutlivedYourUsefulness: [[spoiler:Towards the end of the game, Kingdom Hearts nears completion and Xemnas decides that he doesn't need two Keyblade users anymore. He tricks Roxas and Xion into fighting each other with an illusion that makes them look like a Heartless to each other, hoping that one would kill the other.]]
* TheWorfEffect: When [[Disney/BeautyAndTheBeast BEAST]] of all people is tossed over a castle gate by an unseen Heartless, it's enough to make some players [[BringMyBrownPants really, really scared]]. The fact that this boss is considered ThatOneBoss, particularly in its challenge mission, does ''not'' help.
