Sariel has the appearance of a child. He has light blue hair with bangs covering most of his forehead. He possesses four angelic wings on his back, the second pair smaller than the first.
Sariel wears a set of coat-like robes with a symbol of the Four Archangels in his chest, his hoodie resembles that of a halo along with a pair of shoes and black shorts underneath his clothes.
Sariel is very confident in his abilities. He displayed no fear battling the Ten Commandments and looked down on the Demon Clan, incapable of taking them seriously as a threat to himself at first. When Elizabeth explained her wish to coexist with the Demon Clan though, Sariel was willing to go against Ludociel's orders and aid her in returning Derieri and Monspeet to their original forms. He also commended Estarossa for escaping from Elizabeth's Ark uninjured. While blunt and sometimes too honest, Sariel is a person of honor who isn't afraid of standing his will: Despite needing a body for the war, he left Solaseed in order to fulfill his promise;this also proves that he is a person who keeps promises. Sariel will defend his comrades when necessary, pointing out Elizabeth's skills and actions when Deathpierce tried to question her. Unlike Tarmiel, he is calm enough to fight against his previous comrade Mael in order to save him from the Commandments' control, even joining forces with Gowther despite he casted the memory alteration spell on him.
At some point of his life, Sariel was given his Grace by the Supreme Deity. He was close to the four archangels and to the Deity's daughter. Though he didn't really insulted Mael for wanting to look like Ludociel, Sariel was blunt to point out his adoration to his older brother Ludociel, much to the younger goddess' embarrassment and Tarmiel asking him to be more sensible.
Sariel appeared 3,000 years ago during the Holy War. After Ludociel's plan to bait out the Ten Commandments was a success, he arrived along with Tarmiel and declared their intentions of wiping out the Demon Clan members present. When both of them used the Omega Ark, and they managed to kill all the demons except the members of the Ten Commandments, a battle between them begins. Sariel receives Monspeet's Gokuencho by surprise, but he manages to escape the attack unscathed thanks to his Grace. He then manages to cut Monspeet's arm with incredible speed despite the fact that Monspeet had evaded his attack, Sariel then received a blow from Fraudrin in his Full Size while trying to resume the attack, but Fraudrin is also wounded by Sariel's speed. Then, Sariel attacks Monspeet with his speed and cuts his body in half, then receives a punch from Derieri that he had initially blocked with a wall of wind but the attack ends piercing his eye, and then he is attacked by Galand with the Ark he had caught from Tarmiel.
When Ludociel joins the battle and manages to overcome the Commandments, they assume their Indura Transformation. Ludociel orders Sariel and Tarmiel to help him, but Monspeet manages to catch them and injure them severely. After healing themselves, the two Archangels preceded Elizabeth's difficulties in her attempt to save Derieri and Monspeet from their transformation.Ludociel orders them to eliminate the Commandments, but upon hearing Elizabeth's will when they claim that the Demon Clan are their enemies, Sariel and Tarmiel decide to help her with their powers to save Derieri and Monspeet.
Along with the rest of the Goddess Clan, Sariel lost his physical body in order to seal the Demon Clan at the end the Holy War. His spirit pass to inhabit inside a lute.
Sariel appears again manifesting himself from within Solaseed's lute. Revealed by him, when Solaseed was dying of an incurable disease, the Archangel formed a pact with her to cure her illness in exchange for her allowing him to use her body to fight the demons. After taking over her body, Sariel saves and heals some Holy Knights from the hands of a demon attack, claiming to the knights that they will guide them with their words of truth and actions of justice.
Sariel then goes to Liones along with Ludociel and Tarmiel in order to form an alliance between the Goddess Clan, the Sins, and the Holy Knights of Liones. After the official formation of the alliance against the Demon Clan, the Archangels lead a banquet with all the knights, showing furious when Hendrickson asks about the missing fourth Archangel. He then drinks with his companions throughout the night, being surprised by the effects of alcohol on his human body.
During the meeting to decide the battle strategy for the Holy War, both Sariel and Tarmiel are surprised to recognize Mael's Grace within Escanor. When Ludociel recalls that Elizabeth is not part of the Assault Squad to avoid confronting Meliodas, both Sariel and Tarmiel defend her by stating that they need Elizabeth on the battlefield, who gave them a grateful smile.
In the march towards the battle, Sariel discusses with Tarmiel the benefits that Ludociel's Breath of Bless of gives them when converting the Holy Knights into their "pawns". Likewise, Sariel asks what is the reason for Ludociel to choose Hendrickson as a servant when he is not under the effects of such magic, to which Tarmiel responds that he does not know.
During the battle with the demon army, Sariel and Tarmiel release their Omega Ark, eliminating most of the enemy forces with easy. There, Sariel says that although they could not take revenge for the death of Mael 3,000 years ago, this time they will destroy Estarossa. When the demon army is finally defeated, Sariel intervene in the discussion between Elizabeth and Deathpierce, to tell him that he is actually the one who does not know a thing. He explains that Elizabeth spent most of the battle talking to the Demons and making them turn back around and avoid the fight. Deathpierce still questions the princess' abilities saying she was useless after all which causes Sariel to hush him. He explains despite the demons who have to follow Chandler and Cusack's orders, Elizabeth still managed to get dozens to lose the will to fight and turn around.
There, Derieri suddenly falls in the battlefield, followed by Estarossa, who was in search of her Commandment. After Elizabeth cuts Estarossa off by using Ark and crashing him into a mountain, Sariel and Tarmiel followed him, and commend him for taking Elizabeth's Ark unscathed. Estarossa shows false politeness as he recollects the two, asking where Ludociel and Mael were, before mockingly reminding them how easily he killed the latter. Angered, the two Archangels use Shunenbukaki Seijin on the demon, claiming how they will easily deal with him. Estarossa forces his way through their attack and slices them both in the side with Killing Saucer. As their both bodies are covered in darkness and falling to the ground, light pierces through the black shells, and they re-emerge unscathed, now looking like a mixture of their bodies and themselves.
Sariel declares their desire of vengeance over Estarossa, who claims that they are able to show their hatred before him yet are unaffected by his "Love" Commandment due to the Supreme Deity's protection against the Commandments. After Tarmiel avoids Estarossa's attack by melting into water by the effect of his Ocean Grace, Estarossa tries to attack Sariel. However, he protects himself using his Tornado Grace, cutting Estarossa's arm. There, Sariel release the full power of his Grace, gobble up Estarossa in a succession of strong wind gales. There, Sariel and Tarmiel combines their Graces to trap Estarossa in a separate dimension created by their Graces, rendering him unable to break out. Tarmiel and Sariel claim their vengeance is fulfilled as Estarossa is torn apart by Enlil no Tenbatsu, a technique combination of their Graces, that will disintegrate him down to a molecular level to the point where no demon could regenerate. Out of desperation, in a last moment before being eliminated Estarossa absorbs Galand's Commandment of "Truth".
The both Archangels returns to the battlefield claiming to have defeated Estarossa. However, he reappears at the battlefield, with half of his body covered in darkness, surprising the Archangels, saying that only someone with the same power level as theirs would be able to break free from their dimension. Estarossa quickly knocks Tarmiel off, after embracing him and using his darkness to prevent Tarmiel from using his Grace to liquidate himself. Estarossa tries to hug Sariel, but he creates a wall of wind that crushes his body, affirming that he does not mess with demons. However, Estarossa manages to break his wall and break all his bones in a hug. Sariel manages to get rid of him by using his Killing Wind Saucer to split him in half, surprised at his increased power. After Tarmiel uses his Ugatsu Mizubashira to pierce Estarossa, Sariel claims that it is over. However, Derieri claims that Estarossa has absorbed Galand's Commandment, surprising Sariel. Estarossa claims that even with two Commandments, he can not defeat the Archangels and has no chance of defeating Meliodas. He proceeds to absorb Monspeet's "Reticence" Commandment, causing him to go through a second transformation, instantly incapacitating the two Archangels. Tarmiel and Sariel manages to recover and attack Estarossa by surprise, but Estarossa instantly counters, slicing the Archangels instead.
After Estarossa leaves the battle along Elizabeth, Sariel and Tarmiel manages to heal themselves from the injuries. There, everyone, including Sariel, is surprised when Solaseed's body becomes that of an adult woman. Sariel explains that harboring a high-ranking goddess can be stressful for a human body, causing that kind of transformation and suddenly grown up. He also reveals how Solaseed became his vessel, when Howzer asks about the human bodies' safety, Sariel reveals the truth that by continuing to use their Graces, the bodies of Solaseed and Margaret will end up being destroyed. Due to this, Sariel decides to leave the body of Solaseed, having partially regenerated his original body. He claims that he preferred to wait to have his body completely reformed, but he stats that he has a sense of duty to fulfill his promise. Upon emerging in their original form, Sariel and Tarmiel decide to take advantage of the short time they have to rescue Elizabeth from Estarossa and finally kill him. Even knowing that Estarossa is now too powerful, the two claim that the Holy War will not end while he is still alive. He then healed Guila's wounds so that she can continue to fight. King and Derieri then joins them as they want to save Elizabeth.
On the way, Sariel says that he can only think of Estarossa's face, to which Tarmiel says that he mu
st be nervous for take revenge for Mael. However, when Sariel says that he can not remember Mael's face, Tarmiel is surprised because he is exactly the same.
When arriving at the Heaven Theater and finding Estarossa wrapped in darkness with Elizabeth locked up, the four face him. While defending himself from the attacks of an unstable Estarossa with Ark, Sariel is increasingly questioned about not remembering Mael's face and the fact that can't stop of seeing Estarossa's face on his head. There, Tarmiel, Sariel and Derieri end up recovering their true memories that had been altered 3000 years ago. When Estarossa comes out of the darkness with goddess wings on his back, Tarmiel can not believe that "Estarossa" is actually Mael whose pure white wings were tainted with black feathers.
When King attacks Mael after he tried to kill Gowther, Sariel tells Tarmiel that they must join the battle, to which Tarmiel agrees that they must back up Mael, but ends up astonished when Sariel declares that they must help the Sins. Tarmiel recriminates that King protects Gowther when this one was responsible for turning Mael into Estarossa. Sariel says that Mael has control of the Commandments that he absorbed since he regained his power as the strongest of the Four Archangels, but that his soul is corrupted every time he uses his power since the power of darkness opposes the power of Goddess. When Tarmiel refuses to fight his comrade Archangel, Sariel tells him that he must save Mael as a comrade. In the end, Tarmiel and Sariel joins Gowther and King in the battle against Mael.
As the battle begins, Sariel and Tarmiel try to reason with Mael, telling him to give up his Commandments, but Mael refuses, as he tells them that the Commandments are his last hope. Gowther then uses Broadcast to tell everyone Derieri's plan, apart from Mael. Sariel, along Tarmiel, uses his Grace in order to render him immobilized while Derieri attacks him to put him in the condition to remove the Commandments. Everything goes according to the plan, but Mael appeals to Tarmiel, who could not stand seeing his friend being hurt once again, and stops his attack, giving Mael the chance to destroy Derieri's last heart. Mael extracts the Commandment from Derieri and recites the spell to absorb it. Sariel tries to warn him that if he absorbs another Commandment, he will not even be the same again, however, Mael ignores his words and those of Tarmiel and absorbs the Purity Commandment.
The released energy sends Sariel away, being found wounded by Tarmiel who asks him to resist. Sariel's body begins to fade and he affirms that they have failed in their mission. Sariel tells Tarmiel that what he did in spite of having Mael captive was a screw up, and that was his only chance to stop him since the powers of light and darkness will have no effect on him. Sariel says that only a fairy, human or giant could defeat him, but King lacking enough power even to be healed of his wounds and even the possibility that Gowther could attack his soul and spirit will not happen because he is not the same coldblooded unfeeling of the Ten Commandments.
Looking at the huge sphere of light in which Mael locked himself, Sariel affirms that there inside a huge demonic incarnation tries to be born and whatever it is, it is no longer the Mael they know. Sariel states that as much as it hurts, they have failed in everything to save Mael as well as to protect Elizabeth.
As his last words, Sariel asks for forgiveness to the Supreme Deity.
