Nesta

Nesta is the main antagonist of the anime series, ''Dance with Devils. ''He is a vampire king and sworn enemy of the devils. He is voiced by J. Michael Tatum.

History
He was once a human who later decided to become a vampire, in order to escape death. He once pretended to fall in love with a wealthy woman named Marta Tachibana who later died, suffering from an illness after giving birth to her son, Lindo, a dhamphir.

Years later, his loyal minion, Jek brought his niece and daughter of the devil king, Ritsuka Tachibana, after promising that Nesta would left her from her burdens of the grimoire. As Nesta observed Ritsuka, he saw a bandage around her leg and believed that it was one of his vampire minions. Ritsuka tried to explain to him that she injured herself after arriving to his castle, but Nesta ignored her and killed one of his minions, after he cowardly ran away. Nesta then looked at Ritsuka again and told her that she looked exactly like his lover. He explained to her that her brother, Lindo, is actually his son and that he pretended to fall in love with Marta to learn more about the grimoire. This angered Ritsuka. She taunted him and called him a monster, for causing the chain of events, convincing Nesta that grimoire slumbers in Ritsuka's body. Ritsuka asked him how he intends to remove the grimoire from her.
