Lost Girl: Seasons Five & Six (DVD CrunchyRoll)

Bo is a gorgeous renegade. An irresistible beauty. And a deadly succubus. For years, she had no idea what she was - or why every new lover died in the throes of passion. She fled one corpse after another until a chance encounter with the puckish thief Kenzi exposed Bo's existence to the Fae. This ancient society of supernatural beings exists outside the realm of mere mortals. Within their world, there are only two sides: Light and Dark. Each member of the Fae must choose who they will serve. But not Bo. Driven to discover who she really is, Bo vows to live on her own terms - even if it means existing in the abyss between darkness and light. With the help of the mischievous, but loyal, Kenzi, the handsome shape shifter Dyson, and the beautiful human scientist Lauren, Bo will use her powers of seduction to unravel the riddle of her mysterious past.
