A certain pirate's jigoku yoichi

Trafalgar Law (full name "Trafalgar D. Vatiel Law". "D" is a pseudonym, and "Vatiel" is a taboo name), captain of the Heart Pirates, one of the Worst Generation, the user of the Ope-no-Opera Fruit, nicknamed "The Surgeon of Death".

He wore a furry winter hat with leopard spots, had unique black bags under his eyes, two small gold earrings on each ear, and a beard on his chin.

There are also black tattoos similar to the ones on his clothes on the back of his hands and between the back of his hands and elbows. There are large heart-shaped tattoos on his chest and shoulders, and a tattoo of his own pirate group's logo on his back.

There are letters on each finger of both hands, which together mean DEATH. The tattoos on the hands match the leopard spots on the pants, which makes him look very wild.

Luo was born in Flevors, a country known as the "White Town". He was guided by his parents who were doctors since he was young and learned a lot of medical knowledge.

The World Government has long deliberately concealed the fact that amber-lead will emit toxicity when developed and will accumulate toxins in the body of those who come into contact with it for a long time. Residents of Frevans, including Luo, have all suffered from the "amber-lead disease" which will make the patient and their offspring extremely pale and shorten their lifespan, and eventually even cause the patient to have no offspring. However, the residents of Frevans who were kept in the dark at the time still did not realize the dangers of the amber-lead mines and continued to develop and expand the amber-lead industry.

When he was 10 years old, Luo looked through his medical records and found out that he only had three years and two months to live due to PerkinElmer disease.

At the same time, most of the Frevans residents who suffered from Perkins disease developed complications at this time, but because the World Government deliberately ignored it, and the neighboring countries mistakenly believed that Perkins disease was a terrible infectious disease, they successively implemented isolation measures on Frevans and even killed the infected Frevans residents, which finally led to Frevans going to war with its neighbors in self-defense.

The nuns that Luo knew were preparing to flee the country with the children because the soldiers told the nuns that they would let the children go. However, Luo did not follow them because her sister Lamy was still in the hospital. At this time, the nun told Luo that "there is no despair in the world, and the light of salvation full of mercy will surely come to us."

But then the white town was massacred, and Luo witnessed his parents, who were doctors, being shot to death, the hospital where his sister worked being set on fire, and the nuns and companions who told him that they would be saved being shot by the army. Luo was heartbroken, and the country was destroyed in a sea of ​​fire. Later, he hid in a pile of corpses and escaped across the border.

童年的悲惨经历和巨大变故使得年仅10岁的罗人格变得扭曲，在得知自己的寿命仅存3年零2个月（距今16年前）的情况下找到唐吉诃德家族要求加入以在3年内杀死更多的人。

After escaping from Flavance, Law tied bombs all over his body and visited the young Donquixote Doflamingo, asking him to let him join the Donquixote family's pirate group.

Initially, Doflamingo was surprised that a child would brazenly break into his base, and Law told Doflamingo that he wanted to completely destroy everything in sight.

Doflamingo saw the shadow of his childhood self in Law, and expected that Law would become his right-hand man in ten years, so he said that he was engaged in black market trade, and stealing and selling devil fruits was a common thing, so he proposed that Law find a devil fruit that can cure his disease within three years, and agreed to let Law become a member of the Don Quixote family.

After joining the family, Luo learned swordsmanship, physical training, and artillery under the guidance of cadres Diamante, Lao G, and Gladius. Luo vowed to destroy everything within three years, but was frustrated when he was thrown out of the house when he first met Don Quixote Rocinante, and then was deeply impressed by his unique behavior.

Luo attempted to assassinate Rocinante with a knife but failed. Unexpectedly, Rocinante not only did not report Luo's actions, but also chose to cover for him. This continued until two years after the failed assassination attempt on Rocinante.

One day, Law revealed his taboo name and alias to Baby-5 and Buffalo, and was warned by Rosinante that he should not stay with Doflamingo, saying that the root of evil in Doflamingo's character was innate and that he was a veritable "monster". He also told Law that he was actually a blood member of the "D's Clan" who were opposed to the Celestial Dragons and were called the "natural enemies of God."

Seeing how Rosinante was protecting him, Luo gave up the idea of ​​informing the officials because Rosinante had helped him cover up his attempt to assassinate him two years ago.

Rosinante risked angering Doflamingo and took Law out to sea in search of a famous doctor who could cure Perkins disease.

Influenced by the Freifans War and rumors, hospitals in many countries showed discrimination and fear towards the sick Luo. However, Rosinante was still indignant and stood up for Luo, which made Luo, who lost his relatives in the war, feel the warmth of humanity again and was moved by Rosinante's selfless dedication.

Half a year after going to sea to seek medical treatment, Doflamingo suddenly called Rosinante and told them that the navy was preparing a huge transaction to buy the "Surgery Fruit" that could cure Law from the pirates, and hoped that Rosinante would take the fruit himself.

However, because Rosinante has already taken the "Silence Fruit" to become a devil fruit user, he can no longer receive the power of the second fruit, and he realizes that Doflamingo may have discovered his undercover identity.

In fact, he wanted Rosinante to sacrifice himself to perform the immortality surgery for him, so he decided to snatch the devil fruit for Law at the risk of becoming enemies with Doflamingo, the Navy, and the World Government.

Rosinante contacted Sengoku at the Marine Headquarters through Den Den Mushi and confirmed that the Don Quixote family members would be there three days before the transaction in three weeks.

Arriving at Lubeck Island in the North Sea, the navy will ambush on the nearby Svaro Island, taking this opportunity to completely annihilate the members of the Don Quixote Family, including Doflamingo.

However, Law's condition suddenly worsened at this time. The two of them took a small boat to survive the storm and successfully arrived at Mignon Island three days before the transaction, where the pirate and former naval officer Dias Barreiros who wanted to trade with the navy was stationed.

Rosinante used the power of the "Silence Fruit" to attack the pirate group to which Diaz Barrerus belonged, successfully seized the "Operation Fruit" and made Law take it, but was shot and wounded by the enemy on the way to meet up with Law.

After using up all his strength and being unable to move, he entrusted Law to deliver the key information that could save Dressrosa to a specific navy. However, he did not expect that the specific navy was actually Vergo, the first generation Red Heart "Obsession" sent by Doflamingo to the navy as a spy.

Rosinante saw that his undercover identity was exposed, and even the key information he was going to hand over to the navy was intercepted by Vergo. He was also beaten seriously by Vergo. In addition, Doflamingo instructed his cadres to arrive on the island to kill him, and used the power of the devil fruit to form a "birdcage" to trap everyone on the island. Rosinante also realized that his life was coming to an end, so he also hoped to leave his smile to Law.
