The Pleiades of the Azure Sky「蒼天の六連星, Sōten no Rokurensei」 are a group of Holy Knights of the Kingdom of Liones led by Denzel Liones, the Assistant Great Holy Knight. They were assigned to guard the borders of the kingdom by the two Great Holy Knights, Dreyfus and Hendrickson.
During the award ceremony held in honor of the Seven Deadly Sins' liberation of the kingdom, three of the Pleiades of the Azure Sky, Deathpierce, Dogedo and Waillo, stepped forward in objection. Having been assigned to the borders of the kingdom, they wished to witness the strength of those who saved the kingdom firsthand. Bartra reluctantly agrees to a friendly match between Meliodas and Dogedo.
Meliodas easily dodges Dogedo's attacks and retaliates with his own. Death Pierce concludes that they've seen enough and leaves, revealing that Dogedo's close friend had lost his life during the battle with Hendrickson.
When Fraudrin of the Ten Commandments arrives at a town near the borders of the Kingdom of Liones, two members of the Pleiades of the Azure Sky, Arden and Deldry, ambush him using their Powers, Vain and Love Drive, to weaken him. Waillo then knocks out the weakened Fraudrin, and the three drag him away while Grayroad watches them unknowingly.
While Denzel and Deathpierce take care of interrogate Fraudrin, Deldry, Arden and Waillo are tricked by Grayroad to allow her to release Fraudrin with their Incantation Orb. Before leaving, Fraudrin stabs Deldry and attacks the rest with Break.
After Dogedo manages to prevent their deaths, the Pleiades reunites with some Holy Knights from Liones to talk about the situation of the Ten Commandments.
During the invasion of the Ten Commandments in Liones, the Pleiades helps to protect the royal family. During the subsequent battle, two members, Denzel and Dogedo lost their lives. Denzel is killed by Derieri after being possessed by the goddess Nerobasta and Dogedo falls victim of Grayroad's Pacifism commandment.
When the Four Archangels form an alliance with Liones to face the Demon Clan, the Pleiades shows their discomfort because of the death of their leader at a goddess's fault. In order to get their loyalty, Ludociel uses Breath of Bless on them, giving them a power boost but, at same time, brainwash them to turn them into his pawns.
As the new Holy War begins, the Pleiades form part of the Search-and-Destroy Force that will directly face the Demon Clan army and clear the way to Camelot.

- The Pleiades of the Azure Sky share a number of similarities with the Seven Deadly Sins:
- As seen in their fights with Fraudrin, the Pleiades emphasizes teamwork and coordination. This is in contrast to the Seven Deadly Sins, whose greatest strength is their lack of teamwork, according to Meliodas.
- Both groups directly serve royalty of the Kingdom of Liones. The Seven Deadly Sins serve Bartra Liones, King of Liones, while the Pleiades serve Denzel Liones, his brother.
- In Greek mythology, the Pleiades represent the Seven Sisters, daughters of Pleione and Atlas, who were turned into stars to comfort their father.
- In Celtic mythology, the Pleiades were associated with mourning and funerals, which may have served as inspiration for Denzel's ability, Judgement, enabling him to bring forth the ghosts of the dead to haunt his enemies.
- Deldry is the only female in the Pleiades of the Azure Sky.
