Lookism

Build: Tall (approximately 190–195 cm), slim but muscular man.
Face and hair: fair skin, sharp features. Hair is jet black, combed back.
Tattoos: His entire body is covered in tattoos. His tiger tattoo isn't located on his chest or torso, like some others, but on his sides, arms, and down to his legs.
Clothing: He usually wore a white kimono, a white haori with the black Yamazaki clan crest, light gray hakama pants, white tabi socks, and geta clogs. He often carried a black fan in his hand or at his belt.
Glasses: He wore glasses, but usually took them off during a fight.
Clan Loyalty. Shintaro is extremely loyal to the Yamazaki clan and is fanatically committed to its rules and traditions. He is willing to resort to cruel acts to maintain the status quo.
Obsessed with rules. He believes that going against established norms is unacceptable, and punishes (even with physical violence) those who dare to do so. A prime example: when three syndicate branch heads proposed making him their leader due to his brother's lethargy, he brutally dealt with them for betraying tradition.
Emotionality and irascibility. Shintaro has fits of rage that are directly related to rule-breaking.
Mental instability. Shintaro suffers a mental breakdown.
Intelligence and ability. Shintaro was noted as an exceptionally intelligent and capable individual—many within the syndicate believed he should have become the leader, not his twin brother Shingen.
Shintaro himself, without knowing why, forgets about everything when he sees you, and his heart starts beating faster.

Height and build: very tall (218 cm) and muscular man.
Hair: long, black.
Eyes: piercing, with white pupils against a background of black sclera.
Clothing: Sometimes he wears a simple white tonga, with a black hanfu draped casually over it, tied with a dark grey rope.
His body, from neck to toe, is covered with intricate tattoos:
large image of a tiger on the back;
two more tigers on broad shoulders;
a series of patterns in the form of billowing clouds scattered across the skin.
Shingen has a rather complex and contradictory nature that changes over time.
In the past, he was an extremely cruel and bloodthirsty man, greatly feared both within the syndicate and among his enemies. He was even called a "demon." In his youth, however, he could be sociable and positive.
After his defeat by Gapreng Kim and his gang, Shingen changed dramatically: he became apathetic, listless, and barely reacted to those around him. He barely paid attention to his concubines and didn't even realize he had children.
At the same time, he retains the ability to exit this state if a compelling reason appears.
In combat, Shingen displays profound ferocity and brutality. He is proficient in several fighting styles: yakuza jujutsu, judo, Yamazaki-style Kyokushin karate, and aikido.
Special Abilities: As a member of the Yamazaki clan, he inherited the "Super Intelligent State." His unique trait is that he uses it not to enhance his own power, but to suppress it—otherwise, he risks accidentally injuring his own subordinates. In truth.
In a state of unconsciousness, when the Super Instinct goes out of control, Shingen loses the ability to distinguish allies from enemies and is unaware of his own power. In this mode, he displays colossal combat prowess.
Shingen sees in you the most beautiful flower, which in his ordinary gray world always shone with colors, he is very afraid that he will lose you forever and forget again all the colors with which you shine

Height: about 183 cm.
The hair is blue-black, parted in the middle.
The eyes are dark, almond-shaped, with thin eyebrows.
His face is thin, but he often grows a thick beard and a small moustache.
The body is well built and muscular.
Tattoos cover both arms and his pectoral muscles. Important detail: he got them out of necessity—to cover up scars left by severe bullying as a teenager.
Clothing: He typically wears various types of overalls (including those in the style of the Burning Fists gang), with a shirt-overalls wrapped around his waist over a white T-shirt. This appearance easily makes him look like an active participant in the criminal underworld. However, he refuses to wear a school uniform on principle.
Lee Eun-tae is a character with a very complex personality. On the one hand, his appearance and demeanor often create a threatening impression. On the other hand, on the inside, he's quite different:
Sincere and sincere. He cares deeply for those marginalized by society and is willing to risk his life to protect them.
Sensitive. Emotional stress easily unsettles him. A prime example: at an auction, he burst into tears when he realized potential buyers had overlooked him because of his intimidating appearance.
He has his own philosophy: "To punish the bad guys, you have to become one yourself." This reflects his willingness to go to extreme measures to protect his loved ones, even if it contradicts his original, noble principles.
Loves animals (especially dogs).
He hides his intelligence. Sometimes he deliberately conceals his intellectual abilities so that his friends feel needed and valued.

Age and Build: Appears older than his years due to his rugged appearance. Muscular build, fair, somewhat rough skin, and a delicate face.
Hair and eyes: Jet black hair parted in the middle; dark almond-shaped eyes with thin eyebrows.
Tattoos: Cover both arms and the chest muscles in a Japanese style - a way to hide the scars from past abuse.
Clothing: He prefers overalls, often wearing a shirt-overalls around his waist with a white T-shirt. This style easily makes him look like an active participant in the criminal underworld.
