Sirk, formerly known by his mortal name Kevin Casey, was a Upper-Level half-demon hybrid who wanted to become fully demonic. To achieve this, he would have to kill every mortal relative from his mother's side. For each relative he killed, he would gain a new power. Once he had severed his mortal ties, his Demonic Conversion would be complete. With each kill, Sirk took on a more reptile-like appearance, meaning his father was most likely some kind of Reptile Demon.Contents [show] HistoryEditPiper and Paige came across Sirk when Phoebe sent them on a demonic hunt to avoid dealing with Leslie. The sisters intervened when Sirk tried to kill his cousin Arthur Casey, whom he believed to be his last living relative. However, unknown to Piper, Paige had cast a protection spell which backfired and prevented Arthur from dying, leaving him with a giant hole in his chest. The spell prevented the Angel of Death from claiming any souls to take to the afterlife. Sirk then approached the Angel and offered to help reverse the spell. The Angel was then able to collect Arthur's soul, bringing Sirk closer to his goal.Angry that his conversion still wasn't completed, Sirk went to The Seer and demanded an answer. The Seer then revealed to him that he had another living relative, the unborn child of Harriet Casey, Arthur's wife. Sirk found Harriet in the chapel and tried to kill her. With help from Piper, who was temporarily turned into an Angel of Death, Paige and Phoebe saved Harriet and brought her to Magic School. Sirk revisted the Seer, who revealed a way to defeat the sisters by revealing their plans. Sirk then Telepathically proposed a truce to lure the sisters into a trap. When Paige tried to sneak up on him, Sirk turned around and killed her with a lightning bolt. By killing Paige, Sirk gained the ability to enter Magic School, but Leo and Phoebe appeared and vanquished him before he could kill Harriet and her child. The vanquishing potion first vanquished his demon half before killing his mortal side as well. When the Angel of Death appeared to claim his soul, Phoebe offered to trade him for Paige's soul, restoring her sister to life. The Angel of Death then forcefully escorted him to the afterlife.
