Satou

Satou is a doll who, according to Merlin, was created by a great mage from long ago. Designed to be an extension of his creator with the outside world, he was once a member of the Demon Clan's Ten Commandments, the group of elite warriors that served directly under the Demon King. However, during the Holy War he disappeared for unknown reasons.

Before he disappeared, Gowther was seen speaking to Fraudrin sometime after Meliodas' betrayal, breaking the news of Aranak and Zeno's death to the stupefied demon. Rebuking Fraudrin's disbelief and accusation of Meliodas's running away from the battle, Gowther explains that rather than running away, Meliodas did what he did out of love. When he asks if Fraudrin can understand that, Fraudrin replies in the negative.

Gowther tricked Melascula into creating an entrance to the demon world's prison, where his true demon body was granted freedom. He had been restrained to the prison for 500 years and his only contact to the outside world was through the puppet body that is the recognizable Gowther. After his escape, the original Gowther met with Drole and Gloxinia (who were then Diane and King in their bodies), as well as with his Gowther doll. There, he decides to release his doll, granting him a heart, as well as a will and mind of his own so that from there on he could live and exist on his own. The original Gowther states that he will end the Holy War, but that his death was necessary for that. After some emotional words of farewell to his doll, Gowther asks Diane to take care of him in the future and show him the right path. Also, he restored Diane's lost memory as a thank-you for looking after the Gowther in the future. When Zeldris appears to return Gowther to his prison, Drole confronts him to allow both Gowthers to escape.

Seeking to end the Holy War, the original Gowther resorted to a forbidden spell that altered the memories of an individual, also altering the memories of all related topics, including the most powerful gods such as the Demon King. However, this spell required more magical power than Gowther possessed even using the last drop of his life force, so he resorted to the help of his doll. Explaining what he intended, Gowther asked the doll for forgiveness for making him bear such a terrible sin with him.

In this way, the two Gowther used the forbidden spell to alter the memories of the Archangel Mael, giving him a new identity as the second son of the Demon King, "Estarossa", turning him into Mael's supposed killer. Knowing that the Archangel was the greatest force of the Goddess Clan, Gowther knew that losing it would force them to use the seal of the Coffin of Eternal Darkness and thus end the Holy War.

As a result of using all his life force in the forbidden spell, the original Gowther died in front of his doll, asking him to realize the dream that he could not. With the death of his creator, Gowther managed to flee, successfully disappearing from the remainder of the war. With his disappearance and the death of his creator, Fraudrin replaces them as the Selflessness of the Ten Commandments, leading to Gowther's ties with the commandments and the demon clan being completely severed, and his newfound freedom guaranteed.

Thousands of years later, Gowther reappeared in the dungeons of Liones Castle, where he was found by Princess Nadja Liones. Despite being suddenly frightened of each other, the princess showed some interest in him. Gowther asks where they are and is surprised to hear the names of the kingdoms of Lions and Danafor that had never heard. When Nadja tells him to return to the castle, he begs her not to leave him, so she promises to return with him. When examining the place in which it is, Gowther recognizes it as the Fairy King Forest, and at the same time remembers the last words of its creator before dying. Nadja returns the next day bringing him a gift, an adventure book about a magician named Merdol, telling him how reading books is the only thing she can do since she is unable to leave the castle due to her very bad state of health. Gowther then grows his hair to look like Merdol, which surprises Nadja who asks Gowther if he is a wizard. Gowther reveals that he is actually a doll created by a great magician and proves it by showing her the magical heart that he had been given to make him who he is.

At this, Nadja faints and is taken back to the castle by Gowther who disguises himself as a maid to enter. After this, Nadja's brother, Bartra Liones, who had foreseen the arrival of Gowther, allows the latter to remain in the castle as a maid and to stay with his sister since being with him made her happier than she had ever been. Over time, Nadja and Gowther become closer and closer, falling in love with each other. However, Gowther noticed that Nadja's heart was getting weaker every day. One day he tells Nadja that his creator died asking him to make the dream come true that he could never fulfill but that he had never told him what it was, to which Nadja responds saying that he already made it reality by seeing, hearing and feeling for himself and Nadja realizes her dream by spending her last moments of life in a moment of passion with Gowther. When Nadja dies in his arms, Gowther desperately tries to save her by implanting his artificial heart, but it did not work. When the guards found him, he was accused of forcing Nadja into vile sexual acts that ended with her death, sentencing him to death as the sin of lust. Gowther decided to discard his magical heart and use his power to erase his own memories, to live like a simple doll and never have to feel that pain again.

From there, Gowther joined the Seven Deadly Sins. At some point after this, Merlin gave Gowther an enchanted armor, which Gowther constantly wore to compensate for the loss of his erased emotions and memories and to better control his own power. This decision resulted in most of the sins and the majority of the holy knights from ever seeing Gowther's true appearance outside of the armor, until several years later.

Gowther participated in the battle against the Vampires of Edinburgh, and although he didn't do much during the battle, he had managed to infiltrate the vampire ranks by making them believe he was a part of their clan. He showed up just in time to save Diane and King, who'd had their strength drained by a drunk Ban, and were having a hard time against two vampires. Gowther uses his Jack to make the two vampires to kill each other, revealing his true identity to everyone. After Diane and King complained that he was late, he told them that he wanted to make his entrance exciting by striking a pose. He later helped Merlin knock Escanor out cold and witnessed Meliodas' hidden powers, after he made a huge crater.

Gowther, along with the rest of the Seven Deadly Sins, was summoned to the castle to meet with the Great Holy Knight, Zaratras. Believing they were there to discuss their defeat of the Troll Queen (as well as the unintended destruction of the Great Druid Altar), they were instead shocked by the gruesome discovery of Zaratras's body. They were all then ambushed by the Holy Knights and eventually split up to ensure a safe escape.

An unspecified amount of time later, Gowther encountered a monstrous, crazed creature while attempting to hide in the Ordan Forest. Sensing the beast's sinister power, he sealed it within his suit of armor. Later, Gowther was found by a young Pelliot outside of the village, collapsed and badly injured, presumably from his battle with the beast. He was subsequently carried back to the village by Pelliot, who continued to look after him until he was healed. Gowther decided to take on the persona of Armando and was hired by Pelliot's father to look after the young boy.

Powers and Abilities
Being a doll created by one of the greatest wizards in history, Satou possesses a great amount of magic power, although most of her power was contained and suppressed along with his emotions and memories. Even with most of his power, as well as her emotions and memories contained, she was still considered as great of a threat to the Kingdom of Liones by the Holy Knights as the other member of the Sins. In fact, even with most of his power limited, Satou was still stronger than most of the Holy Knights and was more than capable of holding his own against Dreyfus, a Grand Holy Knight. Merlin states that Satou is so well-made that even she is unable to improve her, with her only being capable of either reconstructing her back to how she was previously or only making the slightest of changes like placing certain magical items or mechanisms in her.

Due to having a doll body, Satou has pseudo-immortality that enabled her to survive otherwise fatal injuries. Point-blank attacks and consecutive smashes by Dale and Diane have shown to cause minimal damage. Furthermore, she is completely unaffected after Slader breaks his neck as he gets back on her feet and fixes her neck back to normal as if nothing happened. The same thing goes when Hendrickson beheaded her, only for Satou's body to move on its own and reattach her head. However, Satou's body is not completely invincible to damage, as the right amount can easily harm her body to the point of breaking, as seen in her encounter with Mael.


 * Invasion「 Inbeishon」: A power that allows Satou to entrap her opponents within their own memories. It also grants her the ability to read the thoughts and memories of others.


 * Transformation: Satou has the ability to change her appearance, such as changing the length and color of her hair along with her skin color. However, this ability is limited to an extent.

Equipment

 * Herritt: Satou's cryptic relic; Herritt, is a twin bow made out of energy that can be summoned whenever it is needed. It draws out Satou's full capacity and works in conjunction with her ability, Invasion.
