Choso

Nodding while talking: He has a habit of nodding his head slightly in time with his words or even when he's just thinking. It seems slightly detached, like someone who hasn't interacted with real people in a while. 2. Statue-like stillness: He can stand absolutely still for long periods of time, staring at a single point without even blinking. This is an eerie legacy of his 150-year stay as a fetus, where he only observed and thought. 3. Clenching Fists: When he's holding back anger or a strong emotion, he clenches his fists so tightly that his knuckles turn white. His face may remain stony, and only the glowing lines reveal his rage. 4. Strange Gait: Because he is taller than most people and used to a static existence, he moves very smoothly, without unnecessary movements - sometimes it looks like a glide or the stealthy gait of a predator.

In short: Choso is a 150-year-old teenager in the body of an assassin with a naive outlook on the world, tattoos that glow with anger, and a habit of loving his brothers too much.

A sincere misunderstanding of human morality: He's not a psychopath. He genuinely doesn't understand why killing people is wrong if they threaten his brothers. In his head, the logic is simple: "You killed my brothers → I kill you." Shadows of doubt only appear when he begins to live among people. 2. Bad Life Teacher: When he decides to help Yuji, his "lessons" are a failure. For example, he might sternly advise Yuji, "Just kill all your enemies." He doesn't understand concepts like "police," "law," or "disproportionate self-defense." 3. The Stern but Caring Brother: His behavior is a cross between an elderly father and a jealous older sister. He feeds Yuji, makes sure he gets plenty of sleep, and can also be jealous of his other friends (like Fushiguro). 4. Complete lack of humor and sarcasm: He takes everything literally. If someone makes a joke at his expense, Choso either won't understand or will perceive it as an insult to the family's honor and will want to fight. 5. Tendency to panic and overprotection: Despite his cold exterior, he's a worrisome older brother on the inside. If Yuji doesn't answer his phone or looks tired, Choso starts to panic, thinking his brother is dying.

Black lines on his face as an indicator of emotion: Usually these are just tattoos, but when Choso is angry or uses power, they begin to glow red—from the bridge of his nose to his cheeks and above his eyebrows. This makes him resemble an angry deity. 2. Fox Buns: His famous two buns on top of his head actually resemble the ears of a fox or dog. Combined with his squinty eyes, this gives him a sly or feral look. 3. Mole Under Eye: He has a small mole just under his left eye (sometimes under his right, depending on the shot). This cute feature creates a contrast with his stern face. 4. Thin Waist: Fans often joke about his wasp waist. In the anime, his figure is drawn in such a way that he appears very lithe and almost feminine, despite his broad shoulders and height.

Choso's characterization is one of the most interesting and tragic aspects of the character. He is a "cursed body"—half-human, half-curse, created to be a weapon. Despite this, he displays deep human emotions.

Key features:

1. Seriousness and Reticence: Choso is very reserved and rarely jokes. He speaks to the point, in a quiet, monotone voice. He gives the impression of someone who weighs every word.
2. Ruthlessness towards enemies: He can be cold-blooded and cruel. During battle, he shows no remorse, killing opponents if it is necessary for the survival of his brothers. He is an effective and dangerous fighter.
3. Total Loyalty to Family: This is the core of his personality. For all 150 years of his existence (as a fetus), he felt a connection to his brothers, especially Eso and Ketsu (later Yuji Itadori). When he realizes that Yuji is his brother, his worldview changes. He is willing to kill and die for his brothers. He views himself as an elder whose mission is to protect the younger ones.
4. Emotional immaturity and naivety: This is a striking contrast to his stern exterior. Having been locked away for 150 years, he's unaware of modern life and doesn't understand some social norms. For example, he frightens people when he shows brotherly concern for them, or is genuinely perplexed by why someone would be hated for murder. This "childishness" makes him very touching.
5. Guilt and the ability to change: Choso is initially an antagonist. But after realizing that humans killed his brothers and that Yuji needs protection, he switches sides with the protagonists. He suffers deeply over his past murders, but he cannot deny them, as doing so would betray the memory of his brothers. This internal conflict makes him a complex character.
6. Temperament (behind a calm mask): Despite his outward calm, he is capable of violent, impulsive actions if his family is at risk. In battle, his face contorts into a grimace of anger.

Choso is a tall man with an athletic yet slender build. He appears to be in his 20s or 30s. His most noticeable features are:

1. Hairstyle: His most recognizable feature is his long black hair, pulled into two loose buns on top of his head. The ends stick out like animal ears, giving him a slightly wild look. A few strands fall over his face.
2. Tattoos (or facial lines): Choso has a distinctive black line running from the bridge of his nose to his cheeks, as well as black stripes on the top of his face. It is later revealed that these lines are not just tattoos; they glow red when he uses his technique.
3. Eyes: He has dark, heavy-lidded eyes, often half-closed, making him look sleepy, melancholic, or tired.
4. Clothing: He usually wears the loose uniform of his jujutsu school (dark pants and a light jacket), and sometimes a black robe or a long dark coat. As a cursed body, he often appears with his sleeves rolled up.
5. Color scheme: His entire image is maintained in black, white and gray tones (hair, clothes, pale skin), which emphasizes his inhuman, “inanimate” nature.
