History[]

Just like the rest of the village, Kaseki is a primitive human. Kaseki is also a descendant of Byakuya Ishigami and his crew. In his youth, Kaseki loved crafting all manner of creation. However, this made the other villagers look at him with disdain as a result. Kaseki built the bridges that connect Ishigami Village and started creating shields for the tribe.

Synopsis[]

Kingdom of Science Arc[]

Kaseki is introduced as one of the inhabitants of Ishigami Village. Upon hearing rumors of Senku, a boy from outside the village, he found it curious.[1]

Suika borrows lacquer from him to aid in making the generator.[2]

In order to create glass vessel, Chrome solicited Kaseki's assistance, tying him up and dragging him back to Senku. The old man at first refused to help them due to his treatment, but became intrigued by their attempts at glass work. When Senku and Chrome attempted to amateurishly blow glass and fail, it infuriated him to the point that he broke through his bonds and took over the process.[2]

Along with Chrome, Kohaku and Suika, Kaseki aids Senku in making gas masks in order to acquire an antibiotic for Ruri.[3]

Ginro tries to rationalize his lack of help in gathering sulfuric acid, saying that it's a given he would be scared since there's a risk of death. He criticizes them for being reckless while posing as being brave. Kaseki interrupts him by saying he's showing his own weakness by running away and saying nothing, then painting them in a bad light over it.

As Ginro tries to protest, Kaseki tells Ginro that he's not weak at all - fear being a key feeling for survival. The former adds that every human feels fear deep inside. Kinro who has a blurry disease is about to fight Magma, and Kaseki says he surely must feel fear. However, with a reason and for the sake of what's precious, someone can eventually beat that feeling of fear. Kaseki intentionally leaves the additional gas mask for Ginro.[4]

Village Games Arc[]

Kaseki plays a crucial role in village games as he suggests winning over the village tournament to acquire alcohol to Senku, prompting the latter to join himself.[5]

Kaseki comments on Ginro's selfish attempt to win the village games himself after misunderstanding Ruri's formal statement that she is indifferent about marrying the winner of the competition. He states that Ginro is even worse than Magma since he has no ill intent behind his actions.[6]

Once Senku defeats Ginro by using Suika's helmet as a fulcrum for his spear and hitting him in the groin with the other end, Chrome faints in the next round and Senku is crowned the winner of the bout. Once the latter gets hold of alcohol, he immediately divorces Ruri and snatches Kaseki so they continue working on the cure. He shows of a spinning bamboo structure he made to the group, wanting girls to praise him. Instead, he gets praised by Senku, much to his chagrin. When asked about its utility by Gen, Kaseki says he has no idea what it could be used for.

After Senku tells Kaseki to look forward to tomorrow and leaves, Kaseki grabs Gen and orders him to watch the creation along with him so he doesn't get lonely. As Gen protests, he accidentally rips Kaseki's clothes and reveals his muscle, prompting Gen to comply.[7]

Once Ruri is finally cured, Kaseki comments on her immediate tomboyishness upon recovery, concluding it must run in the family.[8]

As Suika arrives to the battle between Kinro and Magma, Kaseki is relieved to see that she is well.[9]

After Senku became the village chief, Kaseki helped in the advancement of the people in his ways. For the village's advancement, Senku, along with Kaseki, start forging Japanese swords for all their warriors.[10] Senku explains how the task of making these swords is very difficult and tedious, but Kaseki easily learns it. Kaseki was able to make enough swords to equip every capable fighter in the village.[11]

Once the village is set ablaze, Kaseki worries about the spread of the fire. As Suika leads the invaders away from the village, she is congratulated by Kokuyo and scolded by Kaseki for her recklessness.[12]

Communications Arc[]

The craftsman marvels at the possible creation of a cellphone, its properties and its usage as a wartime communication device. He enthusiastically observes the schematics for its making along with Chrome.[13] Senku briefly explains how the voice's small output of electricity is amplified by the cellphone, creating electromagnetic waves which are then received on the other end. The craftsman shares the joy of eating cotton candy made by Senku alongside the rest of the village. [14] Kaseki, along with Chrome, spends three days to build a water wheel/mill. Senku knew about the invention, but is nonetheless greatly surprised the two have achieved such level of craftsmanship without possessing any prior knowledge. The water wheel was then used, along with the cotton candy tool, to create an electrical water-powered generator.[15]

The craftsman club is getting worn by Senku more and more, with Kaseki and Chrome complaining about the amount of workload imposed onto them. Together with Senku, the duo learns about the functioning of gears, making batteries along the way. Kaseki notes that while before he was lazing around in the village, ever since Senku arrived, things have gotten more interesting and fun. The old craftsman states most of the village feels the same way.[16] Excited for new, oncoming projects, Kaseki is both delighted and exhausted with the effort, complexity and trial and error of making new tools for the Kingdom of Science.[17] Kaseki works with the village to gift Senku a present for his birthday, an observatory.[18]

When Chrome asks how they are gonna make a pinpoint device for molding tungsten, Senku states that Chrome has come far enough to think for himself, and that he doesn't need a "professor" to order him around anymore. This motivates Chrome who enthusiastically accepts the job. Kaseki says that he's rather envious of their friendship, saying that he has done craftsmanship all alone and desires a friend like them. Surprised, Chrome responds that Kaseki has already got him and Senku, which prompts the old craftsman into tears. Eventually, Chrome and Kaseki make the tungsten melting device, thereby readying the process of making a tungsten filament.[19] Kaseki is pumped up once more when Senku delegates the task of making a vacuum device for the cellphone to him. He plays an instrumental role in finishing up the project, and celebrates with the rest of the village.[20] The craftsman then aids in the extension of the phone's cords so Chrome and Ruri could test it out.[21] When the record player is made, Kaseki is amazed to hear the recording of Senku's father, the founder of the village. He is left in awe at the song of Lillian Weinberg.[22]

He aids in making a tank to attack Tsukasa's forces.

He later aids Senku in freezing Tsukasa to save his life.

Afterwards, he is especially excited when Senku plans to create a hot air balloon. However, he is disappointed by the simple design but perks up after Senku lists the items needed. He and Senku have Yuzuriha Ogawa complete the cloth while promising aid. He is amazed by her hard work. When Yuzuriha uses the leftover cloth to make modern clothing, Kaseki is used as a model for this.[25]

When the balloon actually flies, Kaseki is very amazed and shed tears at how humanity's desires make inventing possible.[26]

He makes a car to travel with Minami and is shown wearing modern clothing. However his outfit is destroyed after he is told to create mirrors and cameras for Minami Hokutozai.

After a year of construction, the Perseus is finally finished. He joins the Perseus as part of the crew.

Much later, he and the others are petrified by Kirisame under the orders of Ibara. Kaseki's body is shattered and tossed into the sea by Ibara and his men.

He is rescued by Taiju, Ryusui, and Soyuz and is the third member of the Kingdom of Science to be depetrified. Kaseki is excited at witnessing petrification and his rejuvenated body before he is disappointed at the state of his vehicle.[27] He is recruited to help Senku make a drone.[28]

He and Ryusui notice Chrome and asks what his plan is, after he starts to dash ahead.[29]

He is later petrified again by Ibara but not before playing his part in Chrome's plan.[30]

New America City Arc[]

Kaseki is later seen remarking on Chrome's speculation of the Why-man, bringing up the matter on why the Petrification Weapon was on the island. After a new warrior was revived, Kaseki is seen running with Chrome, Ryusui, and Senku back to the ship. He asks Ukyo if the signal of the enemy is nearby and Senku reveals he is on the moon.[32]

As the Perseus sets sail to return home, Kaseki questions whether the ship will be huge and Senku tells him that they will travel the world to gather materials suitable for space travel. [33]

Working with Yuzuriha, the two are tasked with creating a globe. The two recall Senku's remarks and feeling energized at his audacity, they create a massive diagram, complete with cities. Seeing this unbelievable display, Senku remarked they went overboard.[34]

He is very excited to reach land.[35]

Kaseki is later excited at the thought of modifying the enemy aircraft, once the others are worried after learning they had a second one. He and Senku also decide to build a runway for the ship.[36]

While working on the ship, he joins the discussion of Luna with Senku and Ryusui. He remarks on Senku's logical way of dealing with her. He is later seen excited by the recreation of ice cream. After Senku expresses familiarity with Zeno, Kaseki wonders how Senku knows him.[37]

When Senku is shot, he and the others put the plan into action after Suika brings the last bottle of revival fluid. He joins Gen and Chrome in stopping Stanley Snyder from interfering with their plan.[38]

New Stone World Arc[]

Three years later, Kaseki's statue is collected by Suika who was revived earlier. She places Kaseki with her other collected allies.[39]

After the revival of everyone else, Senku revives Kaseki, along with Max, Carlos, Chrome, and Ukyo. He remarks that being petrified always leaves his body feeling more vibrant and if they petrify him countless times, he might live to see the end of their voyage. Chrome jokingly considers that but says they need him for the ship. He watched as Tsukasa and Hyoga later hunted several animals and used their pelts to make new outfits for everyone. That night, he joined the others at the celebration. [40]

Kaseki later works with his allies in building alloy. He is dismayed by how the Perseus got ruined after half a decade and swore to rebuild it, only to be horrified when the others dismantle it for parts to make alloy. However, he moves past his depression once Senku says that they will rebuild it into something faster and better, as Gen remarks on how Senku knew how to comfort Kaseki. After several days of construction, the group construct a factory to build more alloy and Superalloy City is founded with several people being revived to inhabit. [41]
