History VisualNovel / ClockZero

'''''Clock Zero ~ Shuuen no Ichibyou ~''''', also known as ''Clock Zero ~ A Second from Ruin ~'' is an OtomeGame VisualNovel published by Creator/IdeaFactory and Creator/{{Otomate}} for the UsefulNotes/PS2 on 2010, and later [[UpdatedRerelease rereleased]] on the UsefulNotes/{{PSP}}. It received a more updated port with higher resolution graphics and new additional routes on the UsefulNotes/PlaystationVita in 2015, dubbed as ''Clock Zero ~Shuuen no Ichibyou~ Ex Time''.

* {{Bishounen}}: Given the [[OtomeGame genre]], this is to be expected.

* EyepatchOfPower: While it doesn't really do anything, Toranosuke hides his left eye with an eyepatch since his eyes are heterochromic. [[spoiler:As Traitor, he loses the patch and hides his right eye with [[PeekABangs his hair]] instead.]]

* EyepatchOfPower: While it doesn't really do anything, Toranosuke hides his left eye with an eyepatch since his eyes are [[MismatchedEyes heterochromic]]. [[spoiler:As Traitor, he loses the patch and hides his right eye with [[PeekABangs his hair]] instead.]]

!!''Clock Zero~Shuuen No Ichibyou~'' contains the following tropes:
* AbusiveParents: Toranosuke's father beats him (and his brothers)up from time to time, while his mother turns a blind eye to it.
* AlternateTimeline: The dystopic future world Nadeshiko dreams of and eventually travels to comes from an alternate timeline where [[spoiler: she gets hit by a vehicle and goes into a coma, prompting King, a.k.a., future Takato Kaido, to create a world where nothing can harm her, resulting in said ruined world.]] Nadeshiko, can, however, change this future in each of the boys' routes depending on the players' choices, notably, in the Return endings.

* BadFuture: The Ruined World is actually an alternate future from the game's present timeline that was created as a result of [[spoiler: Rain's schemes that got alternate Nadeshiko in a coma in the first place. King's immediate reaction to this following her coma only made things [[{{Dystopia}} wo]][[WellIntentionedExtremist rse]].]] Naturally, the characters involved with Nadeshiko all want to prevent this from happening.

* BittersweetEnding: Regardless of Nadeshiko's choice in the end of staying or returning in each of her boys' endings, she will always have to leave one world [[spoiler: and one version of the love interest in question]] behind. More apparent in the Return endings where Nadeshiko eventually forgets her adventures in the Ruined World over time.

* ChessMotifs: The Government characters from the Black Rabbit paths are all named after chess pieces. King, who is the leader and dictator of the Ruined World, Bishop, one of King's closest [[TheDragon followers]] who is mysterious and unpredictable when matters of the heart come into play like when he falls for Nadeshiko, and Rook, another one of King's two cohorts who is pretty straightforward, holds King's "kingdom" at bay [[spoiler: and can take away his power when needed at the right circumstance, and is the one who is responsible for most of the mess that happens in the plot]]. Nadeshiko is given the designation of Queen, both for her great importance in the plot (as the main character) and to King, making her an invaluable asset to both sides of the war, and then there's her own versatility to account for in all the routes. Wanderer was also originally designated to be the Knight for the Government, which is fitting considering his own unpredictability in the plot as well as his [[KnightInShiningArmor devotion]] to Nadeshiko.

* DoesThisRemindYouOfAnything: [[spoiler: Shuuya]] telling Nadeshiko that [[spoiler: his memory transfer has failed]] is eerily reminiscent of somebody telling their loved one that they are suffering from a terminal disease.

* EyepatchOfPower: While it doesn't really do anything, Toranosuke hides his left eye with an eyepatch since his eyes are [[MismatchedEyes heterochromic]]. [[spoiler: As Traitor, he loses the patch and hides his right eye with [[PeekABangs his hair]] instead.]]

* ForWantOfANail: [[spoiler: Nadeshiko's accident sometime in the near future set off the events that started the entire VN's plot.]] Preventing it from happening would result in a [[spoiler: future where the explosion that triggered the rise of King's tyrannical reign and the tragedies that would occur as a result of it never happened]] leaving everyone to go about their lives in peace. [[spoiler: Nadeshiko's accident will always be prevented in the Return endings somehow and the present character's futures are altered for the better.]] Only [[spoiler: Riichirou's]] Stay ending is this trope explored however.

* HairOfGoldHeartOfGold: Takato and Philosopher. King [[spoiler: aka Kaga-sensei and/or alternate future Takato]] on the other hand is a [[spoiler: partial]] subversion.

* LaserGuidedAmnesia: A gradual example. [[spoiler: Excepting Shuuya's Return ending,]] Nadeshiko eventually forgets all her memories and adventures in the Ruined World, including even the love interests in the routes the player chooses, in the Return endings. However, she will occasionally have [[WistfulAmnesia vague recollections]] of the time she spent with said love interests, bringing her to tears at times, [[ImCryingButIDontKnowWhy even if she doesn't remember why]].

* MentalTimeTravel: How Nadeshiko and [[spoiler: Shuuya]] travel to the future and the past, the former thanks to King's machinations, and the latter thanks to stolen government technology.

* RagtagBunchOfMisfits: Clock Zero is a club full of social misfits formed by Kaga-sensei to help these students make more friends and to help iron out their quirks. [[spoiler: Though he has more ulterior motives behind gathering them together in the first place.]]

* SpoilerOpening: More evident in the PS Vita port, but this also applies to the original ports as well. Silhouettes of the boys' [[spoiler: alternate future selves standing behind them in the opening]] spoil who's who before the VN slowly reveals who they are.

* {{Tsundere}}: Riichirou towards Nadeshiko. [[spoiler: Wanderer, his future self, is more of a [[SugarAndIcePersonality Kuudere]], however.]] and Madoka [[spoiler: and Bishop, his future self]] to Nadeshiko. Nadeshiko herself can be one in some routes too.

* BigBad: Shared between two people, though their roles [[BiggerBad vary]] depending on the routes: King, the government's ruler, and the one responsible for the CrapsackWorld everyone in the future is living in, and Yoshimune, the ruthless leader of the Yuushinkai rebels who abduct Nadeshiko in Riichirou's, Shuuya's, and Toranosuke's routes.
* BiggerBad: [[spoiler: Rain, an acquaintance of Takato's, as he instigated the events that would lead to Nadeshiko's death in the original timeline for the purpose of getting Takato to create time travel technology and make a MadScientist out of him so he can get his dead sister back]].

* EvilVsEvil: The Government, led by none other than the aptly named King, and the rebels known as the Yuushinkai, led by Yoshimune.

* {{Bishoujo}}: Nadeshiko's adult form is noted to be exceptionally beautiful and is drawn as such. Her 12-year old self is also very pretty for her age.

* {{Tsundere}}: Riichirou towards Nadeshiko. [[spoiler: Wanderer, his future self, is more of a {{Kuudere}}, however.]] and Madoka [[spoiler: and Bishop, his future self]] to Nadeshiko. Nadeshiko herself can be one in some routes too.
