Ryuuma

height: 189 cm
age: 47
hair color: black
eye color: black
appearance:
As a zombie, Ryuma is noticeably shorter than Brook. He has bandages covering part of his skull. He lacks eyes and a nose. He wears a kimono with intricate patterns on his body. He now wears a geta instead of the zori from his past life. He also wears a blue headband, but it is slightly modified. He has a blue scarf around his neck that covers part of his mouth, and his Shusui is tied to his right thigh. His hair has turned white. It is likely that it has turned gray with age. Hogback considers Ryuma's body to be quite special.
When Ryuma was alive, he had black hair that was tied in a bun. He also wore khaki clothing and Zori sandals. His facial features resembled those of Roronoa Zoro (frowning expression and narrow eyes).

In life
Additional information: Monsters.
In life, Ryuma follows a strict, personal philosophy around justice and honor. Ryuma firmly believed that saving a life was a debt that must be repaid in good faith, and that repaying that debt was the true path of a swordsman. To this end, Ryuma would sometimes follow someone's request almost blindly, even if it went against his own beliefs. He also believed that fighting should only be done in defense of something, not for the sake of fame.
As a swordsman, Ryuma had a peculiar habit. Whenever someone touched his sword sheath with their own, even if it was by accident, Ryuma was required to immediately accept it as a challenge to a duel. This behavior stems from Ryuma's belief that a swordsman is a sword. Despite his honorable intentions, this habit often led him into unnecessary and bloody confrontations. It seems that he was considered a hero in the country of Vano, because Kin'emon stated that the country was in a dire situation when his grave was robbed.
Ryuma, having heard about the "King's" reputation, hoped to one day fight against him. He believes that this king must have the greatest "Soul of a Warrior," which is possessed by the most worthy opponents. However, the irony lies in the fact that he himself was a "King." This title was bestowed upon him by the people he had saved. He didn't know that was what people called him.
Ryuma also had poor money management skills. Because of this, Ryuma often found himself poor and hungry for several days.

After the resurrection
As a zombie, Ryuma had many of the same habits as Brook, such as a twisted personality, a "Yo-ho-ho" laugh in various situations, and jokes about his undead body. This similarity exists because he possesses Brook's shadow, and as shown in the "Kora Thriller" arc, zombies acquire many of the personality traits of the person whose shadow was used to revive them.
Although Ryuma has the core of Brook's personality, he has a slightly different perspective on things. He has given up on his past as a particular and Brook, and every memory associated with it. So, for example, while Brook cherishes his afro, Ryuma only sees it as a thorn in his side. Ryuma also sees it as a weakness for Brook to exploit in their duel. He also has a distinctly sadistic undertone, behaving quite cruelly towards his "former master" Brook's shadow. It seemed that he enjoyed inflicting physical and psychological pain, as well as playing with him in battle. This was evident when he could have won quickly and easily, being the much stronger of the two. He seems to retain a fondness for combat that is a result of his birth in the land of the Samurai. He is more like Zoro than Brook in this regard, as he felt deep shame after being defeated by Zoro.

During life:
Ryouma uses a stabbing style of combat. His abilities are based mainly on the stabbing type of attacks, however, the cutting type of striking is far from alien to him. Ryouma is also able to emit cutting waves of purple energy from his sword (almost the same as Zoro's pound cannon).
Ryouma was a good swordsman. His skills resembled a mix of Japanese kenjutsu and buttojutsu. His swordsmanship skills are so great that he was able to cut through copper and easily defeated Cyrano (a top-notch swordsman). He was also able to defeat a dragon without much effort, which became a legend in the future. Ryuma is a fast runner with high endurance, and he can land on the ground with incredible precision (as seen during his landing after defeating the dragon). These skills allowed him to survive in the Monsters manga. In addition, he was known as the strongest swordsman of his time, being called the "king" of swordsmen and a samurai carrying the strongest "Soul of a Warrior".
After death
Additional information: Soul Solid.
As a zombie possessing Brook's shadow, Ryuma is capable of performing all of his techniques. However, due to having a much better body, his techniques become much stronger. The difference between them is so great that Ryuma can easily defeat Brook with only a small portion of his power. In addition to Brook's abilities, Ryuma possesses the "Power of Destruction" (破壊力, Hakairyoku?), which is a product of his superhuman strength. With this immense power, he can create cutting waves of wind (Zoro's 36-pound cannon), which can slice a building in half and break a sword in a few strikes, something that Brook cannot do.
Weapons
At some point in his life, Ryuma became the owner of the Shusui sword, one of the 21 great swords. It is distinguished by its black blade and flower-like scabbard. The sword remained with him even after his death. After being defeated by Zoro, he gives him the sword in hopes of satisfying him.
