Chrome (Dr. Stone)/Synopsis

The story of Chrome from Dr. Stone.
==Biography==
===Kingdom of Science Arc===
After observing unusual bubbles in his village, Chrome decides to investigate and encounters Senku, introducing himself as the village's "genius sorcerer." Chrome shares some knowledge about the bubbles with Kinro and Ginro, sparking Senku's interest. Chrome challenges Senku to a sorcery battle but is unimpressed when Senku explains the science behind Chrome's tricks. Chrome attempts to shock Ginro with a sulfur ball, but Senku shows him a more efficient method using static electricity. Impressed by Chrome's scientific knowledge, Senku recruits him into the Kingdom of Science.
Inside Chrome's shed, Senku finds various minerals, medicinal herbs, and learns of Chrome's efforts to cure Ruri's illness. Chrome had tested the medicine on himself since no one else was willing. Senku shares with Chrome the world's lost scientific achievements before petrification, motivating Chrome to join their mission.
Senku outlines plans to create antibiotics and sulfa drugs, introducing Chrome to new minerals. They attempt to collect iron sand using a magnet but struggle with the physical effort. They realize that offering food, specifically ramen made from foxtail millet, will win people over. Chrome enthusiastically encourages villagers to try it, including the guard brothers, Kinro and Ginro.
As Chrome and the others work on their projects, they discover Gen's faked death and vow to find the culprit. Chrome gloats at Magma's misfortunes and explains his motivation for helping Ruri.
The group attempts to make glass for antibiotics and Suika's lenses but faces challenges. Chrome and Senku enlist the village's artisan, Kaseki, to help. With his assistance, they complete the science laboratory.
Chrome, Senku, Kohaku, and Ginro visit a dangerous spring to collect water, which contains poisonous gases. Senku decides to pass on his scientific knowledge to Chrome before attempting the dangerous task. Initially hesitant, Chrome eventually agrees, and they promise to watch over each other.
Kohaku discusses the possibility of becoming Chrome's wife if their plan succeeds, but Chrome dismisses the idea. They complete gas masks and venture to the springs, where Chrome overcomes his fear to assist Senku. When the gas mask fails, Chrome falls into the poisonous springs but is saved by Ginro's heroic intervention.
===Village Games Arc===
Chrome plays a crucial role in Senku's plan to manipulate the village games to their advantage. He practices his strategy to target Magma's groin, aiming to weaken him before he can face another opponent.
However, their plans go awry when Kinro is unexpectedly matched against Magma in the first round. Mantle, Magma's accomplice, claims Suika is drowning to distract the group, but Chrome and Senku see through his lies. Despite the slim chance of Suika drowning, Kohaku insists on checking on her. Chrome advises Mantle against cheating since Jasper is watching. To everyone's surprise, Senku reveals an arsenal of poisons, needles, and arrows to thwart Magma. After Suika returns safely, Chrome wins a match against Mantle, who throws the fight to disqualify Kohaku.
As Chrome faces Magma, he is quickly overwhelmed by Magma's attacks, sustaining severe injuries. Chrome's desperate attempt to use Suika's helmet to focus sunlight on Magma fails due to incorrect lens curvature. Despite the pain, Chrome remains determined to win and advance the Kingdom of Science's cause. Gen reappears and asks Senku how long Chrome needs to start a fire. Senku estimates 60 seconds. Gen uses his acting skills to manipulate Magma into believing he can curse him, creating a sense of urgency. Chrome's trembling hand and unstable water threaten their plan, but his resolve steadies his hand, allowing Magma's clothes to ignite.
Magma tries to extinguish the fire but only makes it worse. Chrome opts not to kill him and delivers a well-practiced kick to Magma's groin, causing him to fall into the river, making Chrome the winner and securing the Kingdom of Science's victory. After Senku wins the competition and becomes village chief, Chrome assists in gathering ingredients for Ruri's cure. He's astonished by the complexity of the formula but rejoices when the cure is finally completed.
However, they discover that Ruri's condition is due to mycobacterium tuberculosis, which the cure cannot treat. As Ruri's condition worsens, Chrome, along with the group, supports Senku's efforts to help her. When Ruri is cured, Chrome sheds tears of happiness at her recovery.
===Village Origins Arc===
Chrome expresses surprise upon learning that Senku shares the same name as their village and is taken aback when Ruri reveals her knowledge about Senku before recounting the story. He is in the company of Kohaku and Ruri when Senku deduces that the founder of Ishigami village is Senku's father, Byakuya Ishigami.
===Vs. Hyoga Arc===
Chrome collaborates with Kaseki and Senku in crafting iron weapons for the upcoming conflict against the Empire of Might, led by Hyoga during their second invasion. When Homura, a subordinate of Hyoga, sets the village on fire during this invasion, Chrome plays a role in organizing the evacuation to ensure the safety of the villagers.
===Communications Arc===
Chrome is filled with wonder at the prospect of creating a cellphone, exploring its properties, and considering its potential as a wartime communication device. He eagerly studies the blueprints for making it alongside Kaseki. Senku briefly explains how the cellphone works, converting voice into electricity and transmitting electromagnetic waves. Chrome and the village enjoy cotton candy made by Senku.
Concerned for the safety of Taiju and Yuzuriha, who are now in Tsukasa's territory, Chrome worries about their well-being. Senku reassures him that they are being held as hostages and won't be mistreated. After observing the functionality of gears in cotton candy making, Chrome has a revelation and spends three days constructing a waterwheel with Kaseki. They use the waterwheel, along with the cotton candy tool, to create an electrical hydro-powered generator. The crafting group faces growing demands from Senku, including making batteries and learning about gear mechanisms. Chrome realizes that the light bulbs they produced can aid in exploring the caves they've previously investigated.
Chrome brags about his cave exploration skills, but Senku dismisses the need for additional materials. Chrome insists that future devices will require more resources, like copper, prompting him to impulsively search for them. He returns with the metal needed for their next project, a vacuum tube, and impresses Senku. In the caves, Chrome expresses concern about Magma's intentions, fearing he might stage an accident to eliminate them. However, Senku dismisses this idea. When they come across a fragile stone formation called mica, Chrome is awed by its properties. Magma accidentally pushes Senku into a pit, and Chrome mistakenly believes it was an attack.
Both Chrome and Senku fall into the pit, and Chrome tries to pour water to help them escape. Senku guides Chrome in creating a water transfer device, but Senku begins showing signs of hypothermia. Magma uses his strength to propel Senku out of the pit, surprising Chrome. They discover rare materials, and Chrome apologizes to Magma for misjudging him. When Senku is seemingly kidnapped, Chrome is bewildered but later learns it's a birthday surprise.
Senku entrusts Chrome with more responsibilities, and he works with Kaseki to create a tungsten melting device. Chrome's curiosity about various chemical processes continues, and he helps with crafting plastic and maintaining heat during the winter. When the cellphone is completed, Chrome makes a humorous boast to Ruri instead of the expected confession. He later visits the founders' graves and retrieves a record player for Senku. Chrome listens to Byakuya's speech and is captivated by Lillian's singing. He is also surprised to learn that Senku's father founded Ishigami village.
Captured by the Tsukasa Empire, Chrome tries to impress them with science but ends up hanging above a waterfall. Tsukasa offers him a chance to join their side, but Chrome refuses and is dropped. Ukyo saves him with an arrow and he ends up in a cage. He signals Suika and manages to escape with Ukyo's help. Chrome is amazed to witness depetrification for the first time when Senku revives Tsukasa's sister.
===Age of Exploration Arc===
Upon learning about a flight device, Chrome rushes from the village to Roppongi Hills Mori Tower, surprising everyone with his enthusiasm. He expresses his strong desire to witness flight firsthand and insists on selecting a card from Gen's hand, with the intention of them letting him choose the correct one. He, along with Senku and Ryusui, embarks on a journey in a hot air balloon. Chrome is filled with excitement as he encounters various new inventions such as mirrors, bread, and other innovations.
Later, he experiences a ride on a newly constructed motorboat and communicates with Ruri through it until the signal is lost. He's taken aback when a mysterious individual contacts him, and he demands answers while Ryusui and Ukyo try to restrain him. Senku suspects this individual might be connected to the petrification event. Chrome is eventually recognized as one of the Five Wise Generals of the Kingdom of Science, although Kohaku playfully teases him about his position, which annoys him. They discuss their new adversary, referred to as Why-man by Ryusui, and Chrome speculates that Why-man might be an ally.
Using a radar and a pole, Chrome discovers iron ore, effectively creating a metal detector. This discovery leads to the establishment of an iron mine. After a year of diligent work, the Kingdom of Science successfully constructs the Perseus, their own ship.
===Treasure Island Arc===
During their voyage, Chrome becomes perplexed when he discovers that Soyuz hails from another tribe of Stone World humans on Treasure Island. With guidance from Senku and Ryusui, Chrome comes to realize that some individuals from the island had traveled to Japan in the past and are the ancestors of the present residents of Ishigami Village. 
He also speculates about the possibility of Why-man being a member of this newly revealed human tribe, prompting others to consider this notion, leading to a brief interrogation of Soyuz. However, tensions ease, and Chrome eagerly anticipates their arrival at Treasure Island, remarking on how swift their journey is compared to their ancestors.
Chrome is petrified by Kirisame for trespassing and is admired by Minister Ibara for his attire. He is the first to be restored from his petrified state and, after being reassembled by Taiju and others, fully revived by Yuzuriha. He displays excitement at witnessing petrification and gets updated on their plans. Chrome witnesses Gen's successful negotiation with Moz.
When the Kingdom of Science creates a gun and entrusts it to Yo, Chrome expresses concerns about him potentially using it for personal gain based on their past experiences. However, he observes Amaryllis using her charms to influence Yo's behavior. During a confrontation with Ibara, Chrome witnesses Senku revive Hyoga. He initially harbors internal resentment toward Hyoga for his demeanor but is relieved when Hyoga decides to side with them.
Recalling his first experience with petrification, Chrome begins formulating a plan and rushes ahead, prompting Ryusui to inquire about his intentions. He is petrified once more, but not before signaling for Senku after Ibara petrifies the entire island. Chrome is eventually depetrified by Senku, and he deduces that Senku has won. During the celebration that ensues, Chrome and the others are contacted by Why-man, who shocks them by possessing Senku's voice and attempting to petrify them.
=== New America City Arc ===
He dismissed Suika's hypothesis that Why-man could be Senku since Senku was present with them. Shortly after, he formulated a theory suggesting that Why-man might be mimicking Senku, basing it on the latter's use of the Petrification device. However, the team struggles to unravel more aspects of the mystery. The following day, they revive Matsukaze, who discloses the existence of several other petrification devices.
Senku's announcement that they will journey to the moon to confront Why-man exhilarates Chrome, and he revels in his awe of science. The subsequent day, Chrome actively participates in reviving all those who were petrified. When Matsukaze expresses a desire for his people to have the formula to combat the devices, Chrome inquires about their whereabouts, and the warrior reveals that his lord destroyed them. Chrome sets sail with his companions on the expedition to America.
Chrome participates in the revival of Tsukasa and comments to Nikki about Ruri's assertiveness in encouraging Minami to speak to Tsukasa. Chrome attributes Ruri's behavior to being the older sister of Kohaku, the gorilla, leading to a swift scolding. Subsequently, Chrome embarks on the journey to America with his companions. Amidst a storm, Chrome conceives a plan to navigate safely across it. He collects a rock from their aglomeration and enlists Kohaku to carve it into a prism. Placing the prism into a viewing device with a rocket-shaped hole, Chrome takes it to the deck. By using his device to locate the sun, Senku excitedly identifies the prism as made of calcite, a naturally transparent stone. Ryusui recalls the discovery of calcite in Viking longship wrecks, and Ukyo remarks that the legend appears to be true. The team eventually hits their destination - America, leaving Chrome in awe.
Upon arriving at San Francisco, the Perseus crew splits, with the warrior team trailing the exploration team in case of an attack. Chrome is thrilled at the prospect of exploring America to find corn. While navigating the river, the Mobile Lab is attacked by alligators. The Warriors, driven by hunger and anxious for a contest, successfully fend off most of the predators, making them to run off out of terror. Subsequently, François turns the deceased alligators into burgers to feed the crew, a development that brings him happiness. Chrome is particularly intrigued by the uncovering of corn and Senku's plan.
Following crossing the river, Senku is assisted by Chrome to make a rope for Kirisame. 
Upon Senku's announcement to track the enemy, Chrome is chosen, along with Gen and Kohaku, to embark on the pursuit. Excitement fills him as they prepare to explore foreign lands. He contemplates the dynamic of the group, noting the combination of a mentalist and warrior, and refrains from insulting Kohaku. However, when Gen discerns that the enemy is luring them in and takes offense at being underestimated, Chrome witnesses the determined mentalist instructing him and Kohaku to stand back before venturing forth, making a line that follows.
Following Gen's trail, Chrome, along with Kohaku, discovers the American Fortress. They update the Perseus on the situation, only to be abruptly cut off by Tsukasa. While surveying the fortress, they realize that radio waves can cause them to be located by others.
Tsukasa and his group join them, offering much-needed assistance. However, they receive shocking news that Senku has been shot. Realizing the responsibility now falls on him as the last scientist, Chrome proposes the idea of creating a drill, only to find out that Ukyo and Tsukasa are already familiar with it.
With the help of Hyoga, they create a hole in the fortress. Taiju arrives with the drill, surprising everyone. They receive a Morse code message from Luna, revealing that Senku is her boyfriend. Chrome stays behind to ensure a bomb goes off, causing a cave-in. Stuck with Xeno, Chrome refuses the tempting offer to join forces. He escapes, captures Xeno, and contacts Senku.
Senku and Ryusui arrive, and the group escapes with Xeno. Chrome suggests Dr. Brody as a potential ally, and they contact him, revealing the revival formula ingredients. After escaping Stanley, Chrome bids so long to his comrades, aware of the risks involved.
