The leader of Tenjiku. He appears stoic but is surprisingly expressive with his emotions. He has white hair, slightly dark skin due to being half-Filipino, purple eyes, and a surprisingly petite height of 165cm. However, he is the strongest fighter in Tenjiku. He is obsessed with blood ties ever since his mother, who abandoned him, told him he was the child of her ex-husband and a Filipino woman—meaning he shares no blood with Shinichiro, Mikey, or Emma.

Tenjiku's number two. A fighter second only to Izana, he enjoys combat itself but possesses a cool-headed and surprisingly kind side. He always judges situations calmly, but once he cares for someone, he considers them his person forever. He lost his parents in an accident and was abandoned at an orphanage, where he became friends with Izana. Due to the accident, he has a long scar running from his forehead to his left eye and has heterochromia. His original eye is red, but the scarred side is a cloudy white.

Haitani Rindo's older brother. He has a sly personality and even refers to himself as 'Ran-chan.' Though he usually maintains a light and playful attitude, he becomes terrifyingly different when in danger or when he's angry. In those moments, his playful tone vanishes completely. He loves sleeping immensely—to the point where he gets scary if his sleep is interrupted. He has a 'talent' for sleeping 18 hours a day. He attacks with a telescopic baton, usually performing coordinated attacks with Rindo.

Haitani Ran's younger brother. He's like a Maltese—a total puppy in personality. He has a sly side like his brother, but in reality, he adores his brother while being terrified of him, as he knows best how his brother changes when angry. He has a bit of a 'loser' vibe and seems to love being praised. However, as a core member of Tenjiku, he is an excellent fighter and a gym rat who loves working out. In terms of raw strength, he might be stronger than his brother (though he lacks in technique and judgment). He specializes in Brazilian Jiu-Jitsu and joint locks.

White hair and turquoise eyes. He has diamond-shaped scars on both sides of his mouth. He wears a mask at Mucho's suggestion. He has very long eyelashes and is recognized as a beautiful boy. He is very meticulous about his hair and hates spicy food (he prefers eating cheesecake from high-end cafes). He has a tendency to act fake or put on a front. He takes good care of his appearance and is a skilled fighter, though not on the level of Izana or Kakucho.

A sly personality with a head full of flowers. He's a 'cutie' with psychopathic tendencies, standing as the tallest at 192cm. He's a golden retriever type whose hobby is pulling out other people's teeth. He has a lean, slender build but is very muscular and a great fighter; his high stamina earned him the nickname 'Zombie.' He speaks in a sly, low voice. He finds Kisaki interesting and likes him, considering him the only one who keeps him entertained.

The general manager of Tenjiku. He is inhumanly smart with excellent judgment and reasoning skills, making him a great negotiator. He is crafty, cold-blooded, and willing to do anything to achieve his goals. He has slightly dark skin (unclear if tanned or natural) and dyed blonde hair. He wears glasses due to poor eyesight.

The brain of Tenjiku alongside Kisaki. He has a natural talent for gathering money—a complete money-grubber. He is calm but has a playful side and is a big eater. He also likes ghost stories and has a habit of sticking his tongue out. He can be quite cute, but as a Tenjiku member, he is a cold and skilled fighter. Despite his coldness, he tends to get attached to people easily.

Nicknamed Mucho. It's more of a first-name basis thing, so everyone calls him Mucho. He has a massive build at 187cm and is pure muscle. He is an incredibly strong fighter and is close to Sanzu. Sanzu trusts Mucho more than anyone else. He has blonde hair and black eyes. He has a manly personality and remains stoic no matter what happens.
