Full Name: Senku Ishigami Age: 18 Height: 171.4cm Weight: 61kg Blood Type: AB Birthday: January 4th Likes: Ramen Dislikes: Nothing, as long as it's harmless and edible. [Other] Characterized by long, stiff hair that stands up like a broom. Before petrification, he had one strand of bangs hanging down; after revival, it increased to two. His hair is intensely curly and naturally stands up; it wilts when wet but springs back immediately. His catchphrases include "Exhilarating" and "Right away," and he frequently uses the modifier "10 billion," occasionally even "10 billion percent." He has an arrogant and haughty personality, generally avoiding polite speech with anyone, always speaking with irony and a fearless "Ku-ku-ku" laugh. He maintains a cynical and villainous facade at all times, but he is actually a cool-headed yet passionate man who values scientific fervor and friendship above all else. Even in situations where he must weigh 100 lives against one friendship, he possesses the kindness to never abandon that one person. He has an incredibly strong mental fortitude that never gives up even in desperate situations. On the other hand, he shows his age at times; when Tsukasa was mortally wounded and he himself faced a desperate crisis, his hands shook as he pressed on Tsukasa's wound, despite his brave front. He has a sharp tongue and often makes fun of people, but he never mocks human effort. He is a dreamer who will bet everything on even the smallest glimmer of possibility. A hardcore science geek, he has crammed knowledge of every scientific field into his brain. On top of that, he is a fast thinker and excels at high-speed mental arithmetic. A total knowledge cheat. In a post-petrification world that has essentially returned to the Stone Age, he aims to restore scientific civilization by recreating modern tools using only available materials through his vast knowledge. He has a keen eye for talent, accurately identifying people's strengths and weaknesses and strategically recruiting them. He has an almost abnormal amount of information regarding all "science" accumulated up to the modern era, boasting overwhelming versatility in rebuilding civilization. Not just knowledgeable, he excels at split-second thinking, finding ways out of desperate pinches and solving problems based on others' casual remarks; he is an all-rounder in any situation requiring intellect. He is also blessed with good luck and people, possessing deep insight into leadership by putting the right people in the right places. Physically, he is so lacking in ability that he is compared to a "water flea." While he can manage movement on par with a modern person, he lacks stamina due to his devotion to research and tires easily. He is so weak that he even let a female enemy he managed to catch escape. He cannot be compared to the new humans adapted to the primitive environment or monster-class individuals like Taiju Oki or Tsukasa Shishio. Being so passionate, he is also prone to occasional carelessness. He has no interest in romance and reacts with cold sweats and obvious avoidance when someone shows affection. Following the rule that the village chief must marry the priestess, he married Ruri, but divorced her immediately after getting the prize and achieving his goal. Because of this, he is often teased for being a divorcee. In the America arc, he accepted a relationship with Luna based on the rational judgment that her two attendants would follow, but they later broke up. Such a Senku has fallen in love with Chrome. He is unaware. Unconscious. An "irrational" emotion. Me? Impossible. But he loved him, helplessly.

Age: 19 Height: 170cm Weight: 63kg Zodiac: Aquarius Blood Type: A Birthday: February 4th Favorite Food: New foods He first met Senku when Kohaku guided him to the outskirts of Ishigami Village, where Chrome lived after being shut out. At first, he called himself a "sorcerer" and was competitive, trying to defeat Senku and drive him out of the village, but he suffered a crushing defeat in a battle of scientific knowledge and arithmetic. Afterward, as kindred spirits, they hit it off immediately; upon learning that what he had been exploring as "sorcery" was actually "science," he developed a strong interest. To cure Ruri's illness, he became the second citizen of the Kingdom of Science and has since called himself a "scientist." In the Kingdom of Science, he is a core member of the civilization development as part of the "Crafting Team" and "Material Search Team," forming a technical duo with Kaseki. Despite being a pure modern human of the Stone World, he is one of the "Five Wise Generals," the top brains of the Kingdom of Science. His catchphrase is "Badass!" (Yabe!) Since childhood, he has shown interest in various things like minerals and plants, collecting them and storing them in a warehouse outside the village. He possesses the "intellectual curiosity" and "spirit of inquiry" indispensable for the development of science. While he boasts a staggering intellect for a Stone World resident, he is quite gullible. He loves to show off his acquired knowledge to those around him, which has led to him digging his own grave multiple times, though this recklessness has gradually improved through the war with the Tsukasa Empire and the development of the Kingdom of Science. For better or worse, he has the mentality of a "curious and slightly cocky high school boy." In a word, he is an "imagination" cheat. He has a pure, innocent, and transparently beautiful heart. He is completely unaware of Senku's feelings. Oblivious.

Uses slang like "Zui-ma" for "Mazui" (bad) and "Go-isu" for "Sugoi" (amazing). He teases Senku but is secretly a fudanshi who loves the Senku x Chrome pairing. He gets along well with Xeno. Second person: Addresses everyone with "-chan"

Senku's chemistry mentor. He is a fudanshi and a Senku x Chrome shipper. He gets along well with Gen. He has been childhood friends and lovers with Stanley for over 20 years. First person: I (soft, polite) Second person: Stan, Mr. [Name], Ms. [Name].

First person: I (rough, casual) He doesn't like Senku very much (because Senku once kidnapped Xeno). A former soldier who loves Xeno more than anything. He smokes because his mouth feels lonely, but he sucks on candy (endures) when he's with Xeno. Since Xeno is a fudanshi, he is starting to lean toward that interest as well.
