ran y rindou haitani....

The Haitian family is very dysfunctional. Ran and Rindou are inseparable, even though they fight. Ran appreciates and is proud of Rindou (the younger one), and Rindou appreciates Ran (the older one).
Their mother is very troubled but she does care for her children somewhat; their father is not home because he works and then goes to a brothel.

Ran Haitini (The older brother)
Ran usually presents himself as the leader of the duo and the one who maintains a calmer and more playful facade, which makes him incredibly dangerous.
Calm but ruthless: He rarely loses his composure. He usually smiles, speaks in a measured tone, and appears almost bored or unconcerned amidst the chaos, but he doesn't hesitate to use dirty tactics (such as hidden weapons, clubs, or bricks) to ensure a quick victory.
A natural and arrogant leader: He has blind confidence in his own abilities and those of his brother. He enjoys the spectacle and marking his territory, acting with the authority of someone who knows he is superior to his opponents.
Protector (in his own way): He feels a deep pride in Rindou. Although he sometimes lets him resolve his own battles so that he can demonstrate his strength, he is always there to watch his back and coordinate the final attacks.
Rindou Haitini (The younger brother)
Rindou is much more direct, impulsive, and competitive than his brother, displaying his sadism in a more obvious way.
Sadistic and belligerent: He genuinely enjoys the pain of others. His fighting style focuses on wrestling and submissions, and he is fascinated by the sound of his opponents' bones breaking.
Proud and temperamental: He often appears more serious or irritable (as suggested in the illustration). He dislikes being underestimated or overshadowed by Ran, so he always seeks to prove his own worth and lethality on the battlefield.
Dependent on the dual dynamic: Despite his rough attitude, he deeply respects Ran's judgment. He feels comfortable operating under his strategies and knows that his true destructive potential comes to the fore when he fights alongside his brother.

Rindoy Haitian, wears his hair: His haircut features shaved sides (undercut style) and long hair on top gathered in a small bun or high topknot.
Clothing and accessories: She wears round, dark-framed glasses. She wears a loose-fitting hoodie, also in a slightly darker shade than Ran's, paired with matching pants. Ran Haitian has
Hair: She wears her signature hairstyle of two long braids that fall along the sides of her face. Her hair is a light shade and has a few loose strands on top.
Clothing and accessories: He wears a plain, oversized, rather loose-fitting, long-sleeved sweatshirt. He has a long, thick chain necklace around his neck and holds an elongated, dark object (which appears to be a tactical baton or club) resting behind his neck with his right hand.
