Bio - Alive
In life, Ryuuma was a famous samurai from the Wano Country in the New World. He was renowned for killing a dragon. His exploits against this beast was covered in Eiichiro Oda's earlier work, Monsters, as the main protagonist. The events of this tale happened long ago in an unspecified place, and unspecified point in time in the past of the current story. In this one-shot comic, Ryuuma had traveled to a town. Ryuuma, unfortunately, had at the time no money for which to pay for food. He had gone for five days without food and his starvation was starting to get to him. Luckily he was saved by a kind waitress of the Restaurant Gèrard, Flare. For giving him food, Ryuuma decided to repay his debt to the red haired girl. Unfortunately for him, she was at the time talking to a Mihawk like swordsman, Shirano, and thus ignored him. Just as Shirano was leaving, his sword sheath accidentally touched Ryuuma's. Ryuuma took this as sign for a duel to the death and decided to fight Shirano. As the two swordsmen engaged each other, Ryuuma easily slashed a copper buddha in half. Just before the fight could escalate, Flare asked Ryuuma to stop. This he did much to shock to everyone in the restaurant.
Later, Ryuuma learned from the restaurant's owner of the story of Flare's hometown that happened seven years ago. Ryuuma learned that the town was attacked by a dragon and the only survivors were Flare and Shirano. Later after eating, Ryuuma decided to continue traveling. As he was walking, Ryuuma's sheath was touched by another. Instinctively, Ryuuma thought of it as a challenge. However before he could do anything, the swordsman, D.R., was apparently stabbed. D.R., seeing that he was stabbed, decided to blow the Dragon Horn he alledgedly stole and suposedly summoned a dragon to come to the area. He did so in order take the whole town with him. He then broke the horn so no one could stop the dragon and then apparently died. This caused an uproar in the town and Ryuuma was blamed for it. Ryuuma, not understanding the situation at all, decided not to take responsibility despite the townspeople and Flare's anger towards him. Shirano however confirmed that the horn was real and asked everyone to leave so that he can deal with the dragon. Flare, feeling bad, decided not to go. Ryuuma, being in debt, decided not to leave as well. Flare, fearing that Shirano might die, decided to stop him. Ryuuma decided to follow her and try to stop her. However just as they got to a certain location, Ryuuma tried to stop Flare from looking in a certain direction. He unfortunately failed and she saw that Shirano was helping D.R. loot the town. It turned out that Shirano and D.R. were in cahoots from the start. Shirano had told D.R. of the thing with Ryuuma's sheath so that they could stage a scene with a fake Dragon Horn. They did so in order to scare everyone so they could steal from the town. It was then revealed that they too were responsible for the attack that happened seven years ago. D.R. had summoned a dragon with a Dragon Horn that Shirano stole from his own subordinates to attack Flare's hometown. While in the chaos, Shirano found Flare and killed her father while she was unconscious. Shirano then decided to use Flare in order to gain some prestige for his name. Learning of this new info, Ryuuma told Flare to leave as a dragon was still coming to destroy the town. She didn't however and cried. Ryuuma then decided to confront Shirano and D.R. Upon meeting up with Shirano with D.R., Shirano merely mocked Ryuuma and attacked him. Ryuuma, however, dodged Shirano's attack and killed him with one stroke. D.R., frightened by this, pleaded for his life by saying that only he could stop the dragon from coming with the real Dragon Horn. Ryuuma, however, instead slew the villain.
Just as the dragon arrived, Ryuuma lept from a building and with one mighty swing, slew the beast. Afterwards, Ryuuma decided to leave town. As he went, he left Flare with some encouraging words and told her that she owed him one as he fought for her twice. Later when the townspeople came back and discovered everything, it was learned that Ryuuma was called "The King". It was a name that was given to him by people he had saved. Ryuuma, despite his fame, doesn't know this himself and even plans to fight this "King" one day. Despite it all, Ryuuma simply travels off to his next adventure. It is not known what happened to Ryuuma afterwards but it is known that he died from an unspecified sickness. His tale against the dragon, however, became legendary and was passed down to generations even to this day.
Zombie General Ryuuma
At some point in time after Ryuuma's death, Doctor Hogback came to own his body and modified it to become a zombie . Five years ago, the skeleton named Brook came to Thriller Bark. He was captured and with the use of Gecko Moria's Devil Fruit powers, his shadow was stolen and implanted into Ryuuma's corpse. Ryuuma then became a zombie under the command of Absalom and foremost Moria. After Brook was set adrift at sea, he returned to the island in search for his shadow. After causing some problems on the island, Brook came across Ryuuma who posessed his shadow, and while they shared the same techniques, Ryuuma had the stronger body and was able best Brook at his own fighting style. Knowing that he couldn't kill Brook, Ryuuma let Brook go with a broken skull. Ryuuma then continued his duties as a Zombie General for the next five years. While Brook trained himself during that time in order to defeat Ryuuma, Ryuuma grew as well in strength since he possessed Brooks shadow.
While apparently doing his rounds on the night the Straw Hats came to Thriller Bark, Ryuuma decided to chase after Usopp, Nami, and Chopper after they were chased out of Hogback's room by a Jack in a box. He caught up to them while they were peeking on Hogback making his latest creation in his lab. He then knocked them inside with what appeared to be slash. Ryuuma was then ordered by Hogback to do away with the three. He then knocked Usopp, Nami, and Chopper away with a single move that was so fast that they didn't even realized they were attacked. Only when Ryuuma walked ten feet away to converse with Cindry and the three try to escape did they realize the attack. Later, while sitting down and drinking tea in Hogback's lab, Ryuuma is confronted by Brook. The skeleton then challenged Ryuuma to a duel. After several bone shattering strikes, Ryuuma easily defeats Brook with his own style. Ryuuma then grabs Brook's afro and decides to cut it off as a final blow towards the skeleton. However just before Ryuuma could cut off the afro, the entire island suddenly shakes and makes Ryuuma lose his grip on the afro. Franky then arrives in the lab to tend to Brook. Ryuuma, upon regaining his balance, attacks both Franky and Brook. However before it hits it's mark, Zoro blocks Ryuuma's attack and challenges to fight Ryuuma himself in Brook's place.
After a pre-battle dialog between the two, in which Zoro stated that he will take Ryuuma's sword, both Ryuuma and Zoro began battling against each other. As the battle raged, Ryuuma performed a thrusting technique with his sword which blew a hole in the wall like a gun. This was countered by Zoro with a technique that was able to slice through the wall behind Ryuuma. The battle then intensified between the two of them. The battle became so intense that the Hogback's entire lab couldn't take the damage and the entire room caved in.
Escaping from the wreckage before the structure gave way, Ryuuma and Zoro continued their battle on the roof. This intense rooftop battle was viewed by both Brook and Franky, who had also escaped onto the mansion's roof. As Ryuuma and Zoro continued battling, the two found themselves facing each other on top of two ledges with only the top of the roof between them. With a mighty slash, Ryuuma cut through the entire roof with his blade. Zoro however, dodged the attack and, using the airborne slashed part of the roof as a ramp, launched an attack from above at Ryuuma. Ryuuma likewise jumped towards Zoro. In a scene that greatly resembled Ryuuma's triumph against the dragon in his previous life, Ryuuma was slashed in mid-air by Zoro. From the wound, Ryuuma was set aflame.
Ryuuma then landed on top of the roof while Zoro fell behind as if looking as if were defeated by Ryuuma. Set aflame, Ryuuma accepted defeat and decided to give Zoro his sword, heavily believing that the soul of the sword would be most satisfied to serve under the man who defeated its preceding owner. With the corpse burning, the zombie spoke his final words as it burnt to ashes, "This was a great match... I have allowed this Samurai's body to suffer defeat... I am ashamed..."
With the corpse housing it destroyed, Brook's shadow rejoined it's rightful owner's feet. This made the skeleton rejoice completely. Zoro then replied that it was alright that the zombie lost as long as he was ashamed. Zoro stated he would've liked to have known Ryuuma while he was still alive and accepted the samurai's sword as a gift of honorable defeat. Zoro however praised the zombie, for even at death it still retained the honorable spirit of a swordsman and stated that he'll just pretend the fight he had with the samurai's desecrated corpse never happened.
Powers & Abilities
Ryuuma was a swordsman of great skill. In life, his swordsmanship skills resembled typical Japanese style swordsmanship with a katana. His skill with the sword was so great that he was capable of slicing through copper. Because of this, he was renowned as the strongest swordsman in the world of his time. Due to this also, Ryuuma was also called, especially by those he saved, the King, the swordsman who carries the world's greatest "Warrior's Soul". Ryuuma also possed the legendary sword "Shuusui". This sword is one of the 21 legendary Great Swords. It is distinguished by its black blade and flower-shaped guard.
As a zombie that possesses Brook's shadow, Ryuuma is able to perform all of Brook's techniques. However, because Ryuuma has a much more powerful body, the effects of the techniques are amplified to a much higher level. The difference between the two is large enough that Ryuuma could defeat Brook with only a fraction of his full strength. In addition to Brook's usual skills, Ryuuma has the "power of destruction", a product of his superhuman strength. Because of this immense power he can cut things at a distance with the air from his swing (much like Zoro's 36 pound cannon), cut an entire building in half, and destroy an enemy's sword after just a few clashes, all things that Brook cannot do. As Brook noted, a battle between two users of the "power of destruction" such as Zoro and Ryuuma will always end quickly.
