Kuradeel was a man with pony-tailed,[5] long, black hair.[6] According to Kirito, Kuradeel was a man who looked to be in his early twenties, but due to the wrinkles on his face, he looked much older.[7] He wore a standard white and red KoB uniform with a white and red metal chestplate, greaves and shoes, as well as white metal bracers, brownish-gray gloves and a white cape.[6] After joining Laughing Coffin, he had an insignia of the guild tattooed on his right hand, hidden under his bracers.
Personality
Kuradeel first appeared to be a man who overstepped his bounds to protect the vice-commander of the KoB, Asuna, whether she liked it or not.[5][7] He was also prideful and emotional, exemplified by him challenging Kirito to a duel when the swordsman claimed he could do a better job at protecting Asuna.
Kuradeel was later revealed to be a sadistic killer, illustrated by his enjoyment in murdering Godfree and harming Kirito. A small hint of his dark personality was shown when Kuradeel was about to strike Kirito with a murderous intent during their duel.
Kuradeel came with Asuna to Algade as a bodyguard. He was extremely upset when he learned that Asuna was bringing Kirito into her home, in order to cook the Ragout Rabbit's Meat. He became even more suspicious when he learned that Kirito was a Beater. He made a rash comment about Kirito being a Beater, causing an angry Asuna to order him to leave.
Kuradeel and Kirito's duel
The next morning, he was watching Asuna's home, causing her to run away. He explained that he had been doing so since a month ago because it was a part of his duty. He forcefully grabbed Asuna to go back to Knight of Blood HQ, but Kirito intervened and stopped him. Angered by Kirito's declaration of being a better protector, he challenged Kirito to a 1-on-1 duel. During the duel, Kirito used «Sonic Leap» aimed at Kuradeel's weapon's weak point, destroying the sword that lacked durability. Despite Kirito allowing him to use another weapon, Kuradeel admitted defeat, but made a comment of wanting to kill Kirito. He was then ordered by Asuna to return to their headquarters and to stay there until further orders. He accepted the order and teleported to Granzam.
After Kirito joined the Knights of the Blood, Kuradeel underwent obligatory training with him, Godfree and another KoB member by heading to the 55th Floor's Labyrinth and fighting their way to the top of it. On their way to the Labyrinth, he tried to kill Kirito by setting a paralyzing trap in the drink. After killing Godfree and the unnamed KoB member, he revealed himself as a member of the Laughing Coffin PKer guild. Kuradeel then started stabbing Kirito with his sword several times. When Kirito's HP was about to reach zero, Asuna reached the scene in time and attacked him. She healed Kirito with a crystal, and continued to fight Kuradeel, easily overpowering him. However, when his HP was nearing depletion, he fooled Asuna into lowering her guard by pleading for his life and telling her that he did not want to die and then used the opening to attack and disarm her. However, Kirito had recovered from his paralysis by then and he sacrificed his own left hand, which would respawn after a few minutes, and defeated Kuradeel with his Martial Arts Skill Embracer. With his final breath, Kuradeel called Kirito a murderer before dying.
