Ayato Sakamaki (逆巻 アヤト Sakamaki Ayato) is the fifth son of the Sakamaki household. Ayato along with Laito and Kanato, the triplets, are the sons of Cordelia, daughter of the Demon Lord and the first wife of Karlheinz, the Vampire King.
Ayato has a messy reddish-brown hair with hints of purple color on his nape, with lighter shades of ash brown or light blond to the tips. His eyes are green like Laito's but have narrow pupils like Cordelia's. He also wears a black stud on his right ear.
In Haunted Dark Bridal, he usually wears a white shirt that has brown bordering the top and bottom of the shirt with a black jacket and brown scarf. He wears it with blue jeans with a belt attached to both sides of his pants that hang down and go around his pants. In MORE,BLOOD, he wears a black jacket with a red hoodie underneath. Under the hoodie is a white shirt with a black V collar. He wears it with black pants. He also wears a chain necklace.
His school uniform consists of the black school blazer with an unbuttoned white dress shirt and a untied red tie around part of his neck and the right collar of the shirt. He wears it with the black uniform pants with the right pant leg rolled up to his knees and a pair of red and black sneakers.
Known as the troublemaker of the household, Ayato is an attention seeker and loves mischief. He looks down on others and loves to bully and tease people. He refers to himself most of the time as ore-sama (yours truly) and he calls Yui, chichinashi (breastless).
Ayato is quite the rebel and has a passion for torture device; like the iron maiden and such device can be found in his room. He is also the type who always brags about himself; sometimes commanding everyone to call him Ayato-sama. It is also noted that he eats a lot, although Ayato stated that vampires need to drink blood to savor the taste. His favourite food is takoyaki and gets very angry if someone eats his food.
He is a narcissistic prankster who has an obsession of being the best due to his childhood problems with his mother. Ayato is the youngest of the triplets along with Laito and Kanato. His mother, Cordelia, abused him a lot as a child. Ayato's actions is the mere reflection of Cordelia's harmful punishment and how he has been affected by it, that is why his cocky attitude can be compared to that of Cordelia's.
Ayato uses vulgar language at times. Ayato would insult his mother (even after her death) and his brothers by telling them off and calling them names (almost always giving other nicknames) like calling Kanato as hysteric and Reiji as tableware otaku. He also tends to be arrogant as he always calls himself the strongest and the best. And whenever things go his way, he acts unsurprised.
Ayato is very playful and loves sports; basketball being his favorite. Ayato has stated that anything is fine as long as there's a goal to reach for and that sports is his strong point.
