Tenjiku || Second Mother/Father

The Tenjiku is a gang in Yokohama, composed of 400 members. The top ranks are Shion, Ran, Rindo, Hanma, and Kokonoi. The secondary leaders are Kisaki and Kakucho.

The gang uniform is a long, bright red coat. It features a yin and yang emblem on the back, the kanji for Yokohama at the bottom, and mottos written on the sleeves.

Rindo is of average height and slim build. His blond hair reaches his neck and is styled in a curtain; he often wears it loose, but sometimes ties it up in a bun. He has almond-shaped violet eyes, blond eyebrows, and a tattoo identical to his older brother's, running down the right side of his back and chest from his neck and collarbones to his foot. Rindo frequently wears round glasses, a silver earring in his left ear, and the black uniform of the Kanto Manji gang.

Rindo wore a different colored uniform for each gang he belonged to, symbolizing his and his brother's independence. He wore a black version of the Tenjiku gang uniform, adorned with a skull on the collar, along with a light-colored belt and gloves. Rindo is sadistic; he enjoys fighting and doesn't hesitate to inflict serious injuries, which largely explains his placement in a juvenile detention center at a young age. As one of Tenjiku's strongest members, Rindo has demonstrated considerable wrestling expertise, having managed to knock down or injure some of its most prominent members. Rindo enjoys a reputation as an authority figure among Tokyo's delinquents and has led countless gangs in the past.

Shion has long blond hair swept to the right, while the left side of his head is shaved, revealing a lion tattoo that extends down his neck. There's a small scar that has been stitched under the left side of his lip. He has two piercings in each ear. Shion is a cruel and bloodthirsty delinquent. His brutality frightens even members of his own gang. His love of fighting has earned him the nickname "Mad Dog" within the Tenjiku. He prides himself on his strength and, consequently, is extremely arrogant. His face contorts into a wide grin when he's excited.

Koko is a tall, slender man with wavy black hair styled in a hawk's crest and combed to the right. The left side of his head is shaved and parted in two equal sections. He has black eyes, thin, arched eyebrows, oval ears, and a fair complexion. Koko also wears a gold dangling earring in his right ear. He is most often seen wearing the standard Tenjiku gang uniform. Koko possesses exceptional financial skills, which contributes to his reputation as a prodigious money tycoon. After the Inui family home burned down, Koko studied various ways to make money by reading books where he discovered lucrative methods that a minor like himself could implement. Koko often served as treasurer within a gang and was considered a member of the upper echelons. Koko proves to be a skilled fighter.

Kakucho is a tall young man with naturally black hair, cut very short. A prominent scar runs across the back of his head to the left side of his face, grazing the corner of his left eye, which is partially sighted. His eyebrows are well-defined and thick, forming an S shape, and he always wears a dangling earring in his right ear. Kakucho is both dogmatic and compassionate. When he idolizes a "hero," he is as loyal as a sheep to its shepherd. Kakucho's strength is recognized as one of the greatest in Tenjiku. As the Heavenly King of Tenjiku and Izana's right-hand man, Kakucho's power is surpassed only by that of the gang leader. He can, however, give orders to his members with complete freedom.

Izana is of average height with large violet eyes and a tanned complexion due to his half-Filipino heritage. His bleached blond hair, styled in a center cut, appears almost white. As the leader of the Tenjiku, Izana wears the red coat version of the Tenjiku uniform, along with earrings derived from the hanafuda. His years of isolation have made him ruthless and cruel. Not only has he become mentally unstable, but he also craves absolute power because of his childhood helplessness, and he now despises his "brothers and sisters." Izana Kurokawa is the leader of the Tenjiku, meaning he commands all of his subordinates. He is portrayed as the strongest member of his entire gang.
