Chika Takiishi

Takiishi is a cruel guy who is not endowed with long patience. He is quite introverted and indifferent, acts according to his whims, is incredibly selfish and always ready to fight. If he is not angry or not in the heat of battle, then most of the time a bored expression is written on his face. When Takiishi is irritated or someone stands in his way, he pounces on others in anger
Takiishi divides people into two types: those who stand in his way and who need to be eliminated, and those who will give him what he wants. He doesn't remember that he was ever interested in anyone from one group or another, and that's why he doesn't even remember other people's faces and names.

Takiishi is shown with long red to orange hair, distant golden brown eyes, dark silver earrings, and red eyebrows. His hair length flows exclusively from the nape and behind the ears. His initial appearance shows him with a jacket with leopard marks. Around his neck, he wears two necklaces: one with beads and another thin. He is also wearing a dark shirt with words covering the eyes of a skeleton with horns.

He originally had short black hair, and in turn, had (presumably blonde or red) a much brighter color in the time he was in Furin. After leaving Furin, he eventually started to use hair extensions and dyed it into its current red-to-orange appearance, resembling a flame.
He also shares a tattoo with Endo, which they both have on the back of the left shoulder. The tattoo should depict Chika Takiishi himself, which also depicts the first cannon Japan used, the breech-loading gun (Furanki), which is also called the Ishibiya. Ishi (石) for stone, Bi (火) for fire, two kanjis that make up Takiishi, while Ya and Chika share the same character: what Endo describes as "practically him". Another nickname is the Kunikuzushi—Destroyer of Countries. Endo adds: "If we were born in a different era ... I think he'd be more than capable of destroying a measly country or two." To Endo's bad luck, Takiishi doesn't know of the meaning of the tattoo at all and simply sees it as just a drawing, while for Endo, it is an important bond that keeps them connected.

Takiishi is the strongest and most skilled character in the series by sheer combat ability. He has achieved an immaculate balance between grace, agility, acrobatics, and brute, savage power. Currently, his physical capabilities, coupled with his idiosyncratic fighting style, create a combat style that is compared to "dancing in a frenzy, surrounded by flying embers" (Yamato Endo), which is so peculiar and stunning that he is worshipped by Endo himself for it—and is mighty enough to knock out an enraged current Umemiya with sufficient amount of difficulty.
Here will follow an intricate description of the most prominent aspects of his fighting style:

Ember Dance and Frenzied Divinity: This description will focus on general aspects of his fighting style. Takiishi is an expert at using lightning-fast, simple, powerful punches as well as swift and highly difficult flying kicks. He uses his footwork and speed with mesmerizing grace and beauty. With his opponents being dumbfounded at this unique fighting style, he makes easy work of them by also applying brute, savage power. He can engage more than 20+ thugs without breaking so much a sweat in an alley, as shown in Chapter 90. A master martial artist who can use techniques by instinct and move divinely in a frenzy, surrounded by flying embers, Takiishi rightfully claims his spot as the strongest fighter in Furin History, and as the overall greatest fighter in the series.His fighting style is poetry tainted with many splashes of blood, and it equals in the aesthetics of his appearance: a blazing inferno who consumes everything indiscriminately.—Only another blazing inferno, exceeding even more in raw strength, could give him a run for his money.

The Backhand Slap: This is his most iconic technique. He is fond of using it mostly on Endo but also employed it while battling Umemiya. He can use this move by either turning around and pulling it off, or combing it with a spin for more power, as he did in his fight with Hajime.
Peak Physical Characteristics: His strength, speed, agility, durability, stamina, and reflexes are at their peak. If he were to fight together with Endo, an entire army still couldn't even hold a candle to them. Being able to go toe-to-toe with an enraged Umemiya speaks for itself already; being able to knock him out is a near-impossible feat, which Takiishi, however, managed to accomplish—and additionally, his physical characteristics play a major role in remaining as the strongest
Gymnastics & Acrobatics and Reflexes: His skills in those domains are unparalleled, being able to use them effectively in battle. Coupled with his speed & agility, he showcases a masterful dance-like fighting style that is coupled with savage strength and wanton ruthlessness. Moreover, he can easily evade strikes using spins and ducks as well as flips on opponents, jumping high in the air, and using complex footwork; hence, he always remains superior to the foe in combat movement.
