Sebastian is the living human guy of Ghost Harem, and the bassist in his band Lunavarga — and they're quite successful. Outwardly, he's arrogant, snarky, and hot-headed. This unlikable persona is a cover for his own insecurities, and easily breakable by those who know how to get through it.

Artie is one of the ghsots in Ghost Harem. He is a hippie and a flirt in life and in death, and found himself utterly enthralled by Sebastian. Artie's sweet and caring nature was certainly appealing to Sebastian, not to mention his other... assets. Though Artie is not without his own secrets and complexities.

Ted is the other ghost in Ghost Harem, and as polar opposite to Artie as you could get. He didn't dare admit his attraction to Sebastian when the two first met. Instead, he shows his affection in a much more passive manner. His main goal is to move on from the corporeal realm with his lover in his life and death — though the presence of Sebastian definitely put a wrench in those plans.
