Sten is a large man with a heavily muscled build, similar to Ibara. He has a long braided hairstyle, with hair sticking far out at the sides, and bald at the top of his head. He has a long bushy beard and mustache, bushy eyebrows, and dark prominent circles around his eyes. Similar to his fellow Rakshasa Demons, he wears armor plating on his forearms. He also wears a large Iron pauldron on his left shoulder.
Sten is a serious person who was willing to kill anyone who are the Prime Minister's enemies even innocent bystanders. He also had a tendency to say that whenever he kills a person, he prefer to call it "release their souls".
Some time in the past, Sten trained Prime Minister Honest in martial arts. Sten is first seen along with the other Rakshasa Demon to guard Bolic. While surveying the town for intruders, Sten and Mez manage to see through Lubbock's disguise and the two of them attack the Night Raid member together. He was killed after Lubbock used Cross Tail to crush Sten's heart.
