Ran and Rindo

Ran has a lanky build and a small face with purple, drooping eyes and light eyebrows. His shoulder-length hair is alternately dyed black and light blonde, with the roots and ends being black and the middle part being light blonde. When in battle, Ran often wears his hair in two neatly braided pigtails, but lets it down on occasion. He also has a matching tattoo of his younger brother on the left side of his back and chest, extending from the back of his neck and collarbone down to his torso and the tip of his foot. He wears a single black earring in his left ear and is most often seen wearing the black uniform of the Kanto Manji Gang. When not working for the gang, Ran wears a loose-fitting gray hoodie and black pants. Ran and his brother were known as the most stylish of the gang, causing Takashi Mitsuyu and fashion-loving people to greatly admire them when he was younger. The uniform he wears, which is always a different color than the rest of the members, symbolizes the Haitani brothers' independence, how they never have to or want to be officially part of any gang and solely adhere to themselves as a duo. While in the Skylands, Ran wore a black version of the gang's uniform with a skull design on the collar, as well as a light-colored belt and gloves. In Rokuhara Tandai, Ran wore a black version of the uniform with contrasting white stitching and belt. In Tokyo, Ran also wore a white version of the uniform, instead of the official black color. At the age of 13, Ran's hair was pure blonde.

Ran is capricious in nature towards others, making him seem enigmatic; he is also independent in his own right and only respects his younger brother, with whom he used to rule the Roppongi district,[3] aside from Izana Kurokawa and Kakuchō, who he once served under in the Overworld.[4] This shows the limits of Ran's subordination and respect, as he and his brother as a collective duo were widely known for their exceptional power in Roppongi for much of their childhood, hence his inability to obey and follow orders from his superiors. The limited number of people Ran trusts and respects also contributes to his indifference towards others when engaging in battle. He is indifferent to using clever strategies when eliminating opponents and cares little about the extent of damage inflicted on them. Ran can also be teasing and rather overconfident at times. He enjoys speaking with feigned sympathy when asking for forgiveness from his opponent. During fights, he is very violent and will sometimes resort to tactics that involve using weapons, such as a metal club or bricks, to mercilessly beat his opponent.[6] He also tends to be the center of attention when it comes to any activity he and his brother are involved in. Ran cares deeply for his younger brother, becoming very worried and enraged when he sees him get hurt and often cheering him on during their fights together.

Despite fighting with his fists as a child, Ran often resorts to underhanded tactics in combat, using a club or any other weapon that can cause injury and ensure victory.[9][10] Ran is known to never fight fairly, and justifies this stealthy approach as a means to defeat much stronger opponents.

Rindō is of average height and slim build, with light, neck-length hair styled in a "curtain" style that he often wears down but sometimes wears in a bun.[2] He has purple, droopy eyes, light eyebrows, and he and his brother have a matching tattoo located on the right side of their back and chest, starting from the back of their neck and collarbones and ending at their feet.[3] Rindō often wears round glasses, a silver earring in his left ear, and a black uniform of the Kanto Swastika. Rindō also wore a black version of the Skyward Sword uniform with a skull design on the collar, as well as a light-colored belt and a pair of gloves. In Rokuhara Tandai, Rindō also wore a black uniform with contrasting white stitching and belt. At the age of 13, Rindō wore his short blonde hair in a bun. Around 2003, his hair was alternately dyed black and blonde in layers. At the age of 18, Rindō gained light blue streaks in his short, wavy blonde hair.

Rindō has a very sadistic nature; he takes pleasure in fighting and has no problem with causing injuries of any severity. This was the main reason he ended up in a juvenile detention center at a young age.[4] Although he once expressed his disdain for others perceiving him as the weaker brother,[5] Rindō still takes pride in what he and his brother are capable of, as they are widely known for their authority and fighting capabilities as a duo.[6] However, his arrogance in displaying this confidence was later shown to be the cause of his reckless decision-making, which lost him at least a fight against a much stronger opponent.[7][8] Rindō prefers to maintain a more composed demeanor compared to his brother's rather playful demeanor, making sarcastic remarks and ridiculing his enemies during duels.[9][10][11][12]

As one of the strongest members of the Celestial Empire, Rindō has proven himself to be an expert in fighting, as he was able to knock down or injure some of Tokyo Swastika's more notable members, namely Hakkai Shiba and Soya Kawata.[18] His signature fighting tactic is to lock his opponents' joints and break their limbs,[19] and sometimes use his fists.[20]
