The dreaded Vampire King. Bored with his immortality, he forced his minions to attack the human race in an all-out war. After losing the battle against the white knight Phelios, he was killed, but swore revenge on Phelios' bloodline. Now, reincarnated as a helpless housecat, Duzell searches for the reincarnation of Phelios. At first he thinks it is Ishtar, but after tasting her blood he finds this is not true. In the last volume, he says that if he had to guess without tasting any blood, he would guess Ishtar. As a former vampire, he was quite malicious and selfish, as well as bisexual. However, after he meets Ishtar, his personality softens and through several adventures, he learns what love truly is.
