Satsurō Jin

Satsurō going into battle

“Berserker”

“Flame Emperor”

## Backstory

Born in Wano, Satsurō’s immense talent with the sword was obvious from the time he began walking at merely four months old. At the age of 5, Satsurō was sent to a samurai training academy where the average age for a student to start studying there was 13. Satsurō quickly became the strongest student and had swordplay that was greater than that of even his teachers. However, Satsurō ended up killing both a fellow student in an altercation and a teacher who had tried to stop him from killing the student. He was expelled and sentenced to death after being put in prison. In a fit of rage, Satsurō slaughtered all of the prison guards with his bare hands and snuck into the shogun’s estate, where he stole the supreme grade sword Zanka no Tachi as well as the Berserker-Berserker fruit before leaving Wano on a small rowboat. Satsurō rowed for seven days and seven nights before finally reaching an island with a marine base. He killed all of the inhabitants (including the innocent citizens and a vice admiral who had been stationed on the island) and a single marine recruit managed to escape, telling his higher ups of the terrifying figure that was Satsurō, as well as the fiery hell that he left in his wake. Satsurō was given a starting bounty of 250 million. Eventually, many swordsmen gathered themselves behind Satsurō and appointed him as their captain, along with making him a gigantic pirate ship of wood from the Treasure Tree Adam. When the government found out about both Satsurō’s sword and fruit, his bounty skyrocketed to 2 billion. Eventually, his bounty reached a massive 4.5 billion beri, and he was given the title of Yonko.

## Weapons

Known as the sword collector, Satsurō has a collection of all of the swords of notable enemies he has killed. This collection includes the supreme grade swords Yoru and Murakumogiri. However, Sasturō doesn't use these blades, instead preferring to use his own supreme grade sword, Zanka no Tachi.

### Zanka no Tachi

The Zanka no Tachi is a supreme grade sword with cutting power that rivals that of Yoru. It also has an effect where if you imbue the sword with haki, all of it's attacks will have a flame effect that will set whatever it cuts aflame even if it's not flammable, as well as the extra heat causing the swords cutting power to be magnified even further. The flames created by Zanka no Tachi can only be extinguished.

The Zanka no Tachi is a longsword. It's hilt is black with a red grip and it's blade is a sleek, jet black color. On the sides of the blade are two dragons, one golden and one silver, that swirl around each other, forming a double helix. When the sword is imbued with haki, it lights up, and it's blade becomes a fiery red color, as well as beginning to let off steam due to the sheer heat of the blade.

## Devil Fruit

The Berserker-Berserker no mi is a paramecia type fruit with a few effects. The first effect is a passive ability that makes all of the users physical attributes be multiplied by 2, making the user stronger, faster, and more durable. There is also an active ability that allows the user to change the multiplier to 5x for 3 hours a day. The second effect is that the users lifespan is doubled, and the effects of aging on physical attributes are slowed down by 50%. This does not slow down the effects of aging, just the effects it has on his physical attributes. So while Satsurō may look like he's 102, he has the physical capabilities that a 50 year old would have, but doubled due to the first effect of his fruit. The third effect is that with each enemy the user of the fruit kills, their bloodlust and aura increase a little bit, making them stronger, faster, and have better sensory capabilities for each person they kill. The third effect resets after each battle.

## Haki

Satsurō is a master of all types of haki, and has all of the advanced types of haki other than that of observation haki.

### Observation Haki

Despite not having advanced observation haki, Satsurō is still regarded as being fairly proficient with it. When he uses his observation haki, Satsurō becomes able to see small details for things that are located up to a mile away. however, he is not at the advanced level yet because he believes it to be a waste to time to train something that doesn't directly boost his strength. However, this belief may may have changed ever since his battle 16 years ago. Maybe when he emerges once again things will be different...

### Armament Haki

Satsurō is one of the most proficient users of armament haki in the entire world, and is capable of using advanced armament haki at a nearly unrivaled level. He can use a wide array of advanced armament techniques and has even been the pioneer for the development of many new ones.

### Conquerors Haki

Satsurō has been shown to have used imbuement, an extremely advanced technique using conqeurors haki. An anonymous observer of one of his battles states that his sword wasn't even touching the opponents, but their clash was so great that it split the sky in two.

## Swordsmanship

Satsurō is tremendously skillful with the sword, and is known throughout the world for his skill, not just his sheer strength. At merely 5 years old, he was branded as a generational talent, something that has truly been made obvious to this day. He is commonly regarded as one of, if not the strongest swordsmen in the world.

## Sword Collection

Satsurō's sword collection formerly had a grand total of 41 graded swords, with 2 supreme grades and 10 great grades. However, these were all stolen while he was in hiding, leaving him only having one supreme grade sword in his possession, being the Zanka no Tachi, the sword he primarily uses.

## John D. Silver

Sixteen years ago, Satsurō and his fellow yonko John D. Silver battled. It was an intense battle that lasted for an entire month, ending in a stalemate. After this battle, both Satsurō and John both went into hiding for a sixteen year period. However, unlike John, Satsurō is yet to emerge once again and is still in hiding.

## Crew

Satsurō is the captain of the Berserker Pirates, a group made up of swordsmen who gradually gathered behind him due to his strength on his journeys. His second in command is a swordsman named Noir who has a bounty of 2.3 Billion.
