4	''Dr. Stone reboot: Byakuya'' is a spin-off of ''Manga/DrStone'' focused on the ISS crew and Rei, an intelligent robot Byakuya built. Following the Petrification Event that turned all of humanity to stone, the ISS crew returns to Earth to try and save it, leaving Rei alone. The story focuses on Rei maintaining the space station while remaining hopeful that Byakuya will return one day.
5
6	It should be noted that this spin-off is not canon to the main ''Dr. STONE'' story, and its plot gets directly contradicted by elements of its parent manga.
7	----
8	!!''Dr. Stone Reboot: Byakuya'' contains the following tropes:
9
10	* AlternateContinuity: The fact that Senku and company [[spoiler: don't encounter Rei when they eventually travel to the moon during the manga's finale]], suggests that the events of the manga didn't actually take place in the story canon.
11	* ApocalypseHow: Europe [[spoiler: suffers a ApocalypseHow/Class4 via a [[ColonyDrop meteor strike]]]]. Rei then [[spoiler: sets up a meteor detection/defense system and manages to avert a ApocalypseHow/Class5]].
12	* ArtificialFamilyMember: An interesting take on the trope. Rei, despite being a robot, immediately identifies as part of the ISS crew. And much later, in chapter 8, after numberous brain upgrades, [[spoiler: it ''brands itself'' a member of the Ishigami family]].
13	* BittersweetEnding: [[spoiler: The original Rei ceases to function, but the ISS is remade into a much bigger, more self-sufficient space station. Rei is then remade there as a RobotGirl, with much of its original personality intact, still determined to wait for Byakuya to come and get it in space. Meanwhile, back on Earth, Senku sees the light signal but doesn't realise that it's Rei and the ISS, thinking, like Byakuya before him, that both the ISS and Rei were destroyed many years ago. Chrome intercepts the signal and puts together a sign of its light patterns, but he can't understand what it means since he doesn't know how to read Japanese. However, while there are much bigger problems to deal with (since the story concludes during the time of the antibiotic creation arc), Senku and the gang ''will'' head in space to confront the [[BigBad Whyman]], and there is hope they'll find Rei]].
14	* BodyBackupDrive: Just before [[spoiler: Rei ceases to function it creates one for both it and the ISS in the form of a large physical disks (capable of lasting millions of years). These discs give instructions to a 3D printer which then recreates both the ISS and Rei]].
15	* CameBackStrong: [[spoiler: The newly 3D printed ISS in the final chapter resembles a space city rather than a space station. This description would arguably also fit the newly revived Rei itself, but it's unclear if it's smarter or more capable then the previous incarnation]].
16	* CargoCult: In Chapter 8, the final panel shows [[spoiler: a star sign being set up, as Rei's light signal does its annual appearance]]. The human survivors ''have'' noticed Rei's light signal, they just can't explain what it is.
17	* CatchPhrase: Rei responds with "your assessment is appreciated" whenever somebody addresses it. The response is the same whether somebody is praising how [[CuteMachines cute it looks]] (Lillian) or calling it a "useless" (Shamil)
18	* ChekhovsGun: Remember the RobotGirl model with the inscription "Rei 01" that Senku sees in the first chapter? During the story's final chapter [[spoiler: it's shown that Rei remade itself in her image]].
19	* ColonyDrop: [[spoiler: a giant meteor hits Italy, effectively eradicating it off the map, and turning the entirety of Europe gray. Another meteor is set to strike Japan 500 years after that but Rei manages to set it off course thus averting a planetary apocalypse]].
20	* CoolShip: Rei's ''Reigelion'', a spaceship made out of... space suits stacked on top of each other. It later builds automated versions for collecting satellites and 4000 missile ships to [[spoiler:knock a massive meteor away]].
21	* DecoyProtagonist: The first four chapters are about Byakuya and the astronauts' return to earth. The rest of the story focuses on [[RobotBuddy Rei]] and its efforts to keep the ISS in orbit until Byakuya fulfills [[EmptyPromise his promise of coming back]].
22	* DotingParent: Byakuya acts this way towards Rei at the start of the story. Shamil even comments on it.
23	* DramaticIrony:
24	** Byakuya thinks the ISS and his RobotBuddy Rei have gone down into the earth's atmosphere and been destroyed. Meanwhile Rei is still active in space onboard the ISS trying to keep it in orbit until Byakuya returns. Rei decides to send a light signal to Byakuya to show him that it's still alive and waiting for him. Byakuya [[InternalReveal realises that his friend is still alive and waiting for him]], but unfortunately [[spoiler: he dies before he can tell anyone about it]].
25	** Consequently, Rei keeps working on the ISS [[spoiler: even after 3500 after the petrification event]], without any means to realize that Byakuya has passed away, since his creator [[FailedASpotCheck didn't bother to input any information about human biology and average life spans]].
26	* {{Determinator}}: [[RobotBuddy Rei]] is absolutely '''determined''' to keep the ISS in space for as long as it can.
27	* DoAndroidsDream: They certainly do ponder their existence.
28	* EmptyPromise: Byakuya gives one to [[RobotBuddy Rei]] just before he leaves the ISS. Sadly, the robot, lacking any common-sense programming, interprets this as ThePromise instead.
29	* EverythingIs3DPrintedInTheFuture: At the end, Rei makes a giant 3D printer in space out of [[spoiler:satellite parts]] to essentially [[spoiler:recreate the entire International Space Station, and ultimately, Rei itself]].
30	* ExhaustionInducedIdiocy: Shamil and Byakuya almost get into a CockFight over who should lead the ISS return mission. Lillian quickly breaks up the fight by pointing out that the both of them have been awake for over 20 hours, and that they should get rome rest. [[HypocriticalHumor And then she assumes leadership of the ISS]].
31	* ForWantOfANail: Byakuya and Senku build an orb robot and Byakuya takes it to the ISS. This causes a number of differences to the timeline compared to the canon one: [[spoiler:a meteor wipes out all life in Europe (no better telescope tech to confirm a route to India, at minimum), Rei never notices the Why-Men on the Moon as if they have already abandoned it (how would Senku survive Stanley's squad at Brazil without the devices' global petrification command?) and the ISS has been rebuilt and expanded upon with a new Rei inside instead of crashing]].
32	* {{Foreshadowing}}: Shamil's comment about Byakuya forgetting to input information about human lifespans on Rei turns out to be really important later on.
33	* TheGreatestStoryNeverTold: Rei, Byakuya's RobotBuddy manages to [[spoiler: avert a planetary life destroying [[ColonyDrop meteor-strike]] all by itself]]. But, due to the fact that it's stuck in space, and [[spoiler: its fine memory circuits are slowly being fried by the sun]], nobody will ever find out. Senku ''does'' witness [[spoiler: Rei blasting the meteor off-course]], but he is still TakenForGranite and he doesn't knows it was Rei that did it. The final few pages of the story confirm that [[spoiler: like Byakuya Senku thinks Rei and the ISS perished a long time ago]].
34	** In a less important case, the [[spoiler: damaged memory]] might reduce the chance of anyone learning Rei found a giant alien behemoth trapped in an extrasolar comet it hijacked for building material.
35	* InternalReveal: Byakuya spends his life thinking that the ISS went down and his RobotBuddy Rei is now little more that space dust. Then he sees a light signal and realises that both the ISS and Rei are still around orbit waiting for him to get them. Unfortunately [[spoiler: this happens as Byakuya is laying down drawing his final breath, so he didn't have time to tell anyone about it]].
36	* IslandHelpMessage: Or rather "Space Help Message". Rei sends a powerful light signal to Earth every time the ISS passes over the island the Byakuya and the astronauts have landed. It's meant to show Byakuya that the ISS is still up in space and Rei is still waiting for him up there. Sadly, [[spoiler:the first light signal happens to be the last thing Byakuya ever sees]]. So instead of humanity advancing to the space age in order to reach Rei, a [[spoiler: CargoCult forms around it]]. In the final chapter of the story, it's shown that the message is much more than a simple light signal, [[spoiler: the light twinkles in different places spelling out "Byakuya, I am here"]].
37	* IWillWaitForYou: A non-romantic variation. [[spoiler: During the final chapter Rei decides it's worth waiting for humanity to get back in space and goes back to sending the light signal]].
38	* KillItWithIce: After capturing an extrasolar comet to provide resources to maintain the ISS, Rei discovers a giant, alien beast frozen inside. Rei is merely grateful that the corpse provides organic material for later use.
39	* MundaneUtility: Rei's reaction to finding [[spoiler: a giant space dragon frozen inside a comet]]? "More organic resources".
40	* NonIndicativeName: Despite the title using the word ''reboot'', the manga is hardly one, as it is actually a side story to the main ''Dr. Stone'' manga.
41	* NoOneGetsLeftBehind: No ''humans'' that is. When Shamil, Lillian and Connie miss their landing mark and are hours from drowning, Yakov urges Byakuya to abandon them and land somewhere near mainland Japan, but Byakuya refuses to let any of his comrades die. Someone however needs to stay aboard the ISS to properly guide the return probe, and that someone is Rei.
42	* ParentNeverCameBackFromTheStore: PlayedForDrama. Byakuya may not be Rei's biological parent but he is still shown to behave towards the little robot like a DotingParent and he is completely heartbroken that he has to leave it behind inside the ISS. His last words towards Rei are an EmptyPromise that humanity (and consequently he) will one day return for it.
43	* ThePromise: Just before Byakuya departs from the ISS he turns to face his [[RobotBuddy robot companion Rei]] which has to be left behind and promises that he will come back for it in space. It was meant to be an EmptyPromise which would allow [[RobotBuddy Rei]] to pass on peacefully. Instead, it turns the robot into TheDeterminator, with the single-minded goal of keeping the ISS in space for as long as it can. To that end [[GrowBeyondTheirProgramming it develops problem solving skills, invents advanced technology, builds itself a mini-spaceship]] and even achieves GoalOrientedEvolution.
44	* PyrrhicVictory: Rei's plan [[spoiler: to use 4,000 flying rocket hydrogen bombs to set the planet destroying meteor off-course is ultimately successfull]] but the little robot has sacrificed too many resources to achieve it. It can no longer [[spoiler: upgrade and fix itself and the ISS, and it's too beat up itself]]. The reader can see that both the ISS and the little robot are on their last legs.
45	* ShoutOut: For a 9-chapter mini-series it still packs a few...
46	** The "Rei 01" model we see at the start of the manga is a reference to [[Manga/BattleAngelAlita Battle Angel Alita]]
47	** The "Reigelion" Rei makes to go comet and resource hunting references Anime/NeonGenesisEvangelion.
48	** Whenever Rei upgrades itself, a parody version of [[Manga/DragonBall Vegeta]] pops up to proclaim that its brainpower is [[MemeticMutation "over X thousand!"]].
49	** Chapter 8 references Shonen Jump's 50th Anniversary.
50	* ShownTheirWork: Rei's achievements might be over the top but the space science in the manga is pretty accurate. The authors credit their scientific advisor, [[https://twitter.com/mscoolastro MsCoolAstro]] aka Dr Soyeon Yi.
51	* SkewedPriorities:
52	** When it's time to get back down on earth, the scientists aboard the ISS are more concerned about bringing back their research data, their magazines and their samples, rather than packing something that would actually help them ''survive'' such as tools, medication and food. Lillian can only look dejectedly at the whole absurdity of the situation, while quietly sipping on her juice.
53	** Apparently, Senku and Byakuya programmed Rei with extensive knowledge about [[Magazine/ShonenJump Weekly Shonen Jump]] and Manga/DragonBall, but forgot to add in any common-sense programming or basic human biology knowledge.
54	* TheLastDance: For once not a character's last dance, but rather ''humanity's last dance in space'', performed by Lilian as she laments the fact that this is probably the last time people are going to come to something like the ISS. Byakuya is suitably moved.
55	* TrailersAlwaysLie: The title of the story, Boichi's description and the first three chapters would have you believe it's about Byakuya, the astronauts and their life on Earth after they returned. Nope, [[spoiler: instead the story focuses on Byakuya's RobotBuddy Rei, and its efforts to keep the ISS in orbit and later to protect the earth from a ApocalypseHow/Class5 apocalypse]].
56	* TrueCompanions: The ISS crew in its entirety, Rei included.
57	* WhamShot: The final panel of the penultimate page with the message [[spoiler:"Byakuya, I am here"]].
58	* WhatIf: The story is set on an alternate timeline where Byakuya and Senku built Rei, a robot that ends up maintaining the ISS over millenia and saving Japan from [[spoiler:a meteor crash after another had wiped out Europe]]. In ''Dr. Stone'' proper, Senku never mentions Rei and doesn't find any signs of such destruction during his world travels. Then, when he's preparing to [[spoiler:go to the Moon]], he reflects on how the ISS must have crashed and burned a long time ago. The very end of ''Dr. Stone'' implies this story is the result of Senku and [[spoiler:Xeno]] trying to [[spoiler:change history, as Xeno considers somehow creating an A.I. savior for mankind and Rei is pictured on the background as he speaks]].
