Waillo

is a Platinum-ranked Holy Knight and a member of the Pleiades of the Azure Sky, who serve under the assistant to the Great Holy Knight, Denzel.

Appearance
Wayeo is a short man with a strong build of his size and has black hair and mustache. He wears a loose version of a regal knight uniform.

Personality
Wayeo is a silent person, speaking few words and an observant type being able to deduce as to what Meliodas did against Dogget in their match. Although he was a flirter towards Deldrey and often said "marriage" in his vocabulary.

Post-Kingdom Infiltration arc
During the award ceremony held in honor for the Seven Deadly Sins, sans Ban and King who are at the Fairy King's Forest and Escanor who is still missing, Wayeo and his two comrades, Death Pierce and Dogget, come forward after Meliodas calls out those Holy Knights whispering their doubts and complaints behind his back.

Wayeo watches as Dogget faces Meliodas, and during the fight, Wayeo notes that Meliodas defended and attacked simultaneously, incapacitating Dogget's hands. Wayeo stands by as Dogget is defeated and sent flying back to Death Pierce, who easily catches him, and Meliodas asks who's next to face him. However, Death Pierce, carrying an unconscious Dogget, decides that they've seen enough and they leave the scene. As they depart, Hawk, through Balor's Power Eye, reads their Power Levels.

Ravens arc
Later at Fersen, Wayeo suddenly appears in front of Fraudrin, who is attacking Arden close-range, and blocks the attack with ease, despite the impact destroying part of the town. He flirts with Deldrey about being getting married now, much to her disturbance. He then knocks out Fraudrin with one swing of his blade while shouting, "Marriage!" With their mission complete, the three Pleiades leave along with their captured Commandment.

Abilities/Equipment
Due to being a Platinum-ranked Holy Knight, Wayeo is presumed to be very powerful. He was shown to be strong enough to withstand a formidable karate chop from Fraudrin with his arm and then quickly defeated one of the Ten Commandments with one attack of his weapon although this was probably due to his teamwork with Arden and Deldrey.

Wayeo's Power Level is revealed to be 1710.

Weapons
Wayeo wields a broadsword that he carries on his back.
