Taiju Shiba

Inupi is usually a calm and quiet person. However, he is not afraid to speak his mind and opinions, even if it ends up hurting him. He is very loyal to the Black Dragons and is loyal to Kokonoi, whom he considers his best friend. When he finds people he trusts, he devotes himself to them. He is brave, but willing to show his vulnerable side and open up.

Inui is above average height and of slender build, bearing a striking resemblance to his older sister, Akane Inui. However, he is often seen wearing a uniform, and high-heeled shoes are a common way for him to appear taller. He has pale skin, but his left eye is adorned with a deep burn scar from a childhood fire. His light hair, parted in the middle and styled in a sunflower cut, contrasts with his dark emerald eyes and neutral expression.

Personality
Coco perceives the world as a series of calculations. He acts solely in his own interests; his every move is aimed at profit. He associates with those more powerful than himself, but will turn his back on them once they lose their power.

Although he is highly materialistic by nature and obsessed with money, his penchant for financial gain stems from desperation. When Akane Inui, the girl he liked, suffered burns and severe injuries, the cost of surgery proved too much for her family. As a result, he sought every possible way to obtain money, even logically reasoning that the only way for a young man to make money was through illegal activities. However, as he continued to hire criminals for his affairs, he became consumed with the pursuit of money and gradually forgot his original purpose.

When news of Akane's death reached him, Koko couldn't come to terms with the reality and accept the fact that the love of his life was gone, and he couldn't do anything about it. Now, completely distraught, he becomes attached to Inui both as a substitute for the lost Akane and his money, and as a means of staving off his inner collapse.

Coco has a slender build and is tall. He has black hair styled in a "death hawk," falling freely on the right side of his face, while the left side is shaved in rectangular sections. He has fierce, piercing black eyes and high, arched eyebrows, giving his face a perpetually angry expression. He often wears flamboyant clothing, often matching details on his gold earrings.

Taiju's strength is among the greatest in the series. His punches have knocked opponents unconscious or sent them flying back several feet. He has lifted a bench with one hand and thrown it with ease. Takemichi noted that he has never received a punch even close to the strength of Taiju's.[8] Taiju is strong enough to overwhelm the larger Benkei and Wakasa and then slam them into the ground, knocking them out. Taiju's strength is comparable to South Terano. Taiju's strength is sufficient to knock down and incapacitate several people with a single punch. Taiju is strong enough to knock down and incapacitate opponents simply by ramming them with his body.

Taiju is cruel, violent, and religious. He enjoys the suffering of his opponents and cares little for the well-being of others, even his own family and loved ones. He doesn't care who his opponent is, even if it's a woman or a girl. He trained the 10th generation Black Dragon gang, completely reforming it to operate like an army. Taiju was very cruel to his own brother and sister, to the point of beating them for trivial reasons.

He is a proud man, believing in the superiority of his fighting abilities and the strength of his gang. Furthermore, he is incredibly charismatic, completely captivating the hearts of his followers.

Despite his appearance and violent nature, Taiju is a very devout Christian. He goes to church alone every year to pray on Christmas.

In reality, Taiju loves his brother and sister very much, but his excessive concern has resulted in domestic abuse.

Taiju is a very tall and quite muscular young man, significantly taller than his peers (on average, a head taller). He is the second tallest character shown so far. He has white-blue hair, long and styled. Taiju wears a custom-made Black Dragon uniform, but his jacket is longer and red. He keeps it open, revealing his chest. He has tribal tattoos in the form of a series of swirls on the left side of his neck down to his chest and handwritten tattoos below. On his back, he has a tattoo of a huge cross. He grins wildly and displays all sorts of unusual expressions – one eye opens wider than the other, and a vein pops out on his forehead – when he fights or when he's excited.
