Lance "Galahard" Astaroth is a devil from Nocte Regem, Avernus, almost always seen naked riding a Varanid named "Disco Stick". He worked as a porn star, and as a gigolo to some extent. He loved to say his famous catchphrase, "Want to take a ride on my Disco Stick?" while riding his Disco Stick and stroking his spear. He maintained a good relation with Dantalion family, especially Renn which makes Renn's friend grow even more suspicious about his line of work. Renn once said that Astaroth's nickname name is tasteless, but Astaroth replied that his name sells in his line of work.

Astaroth's name and design were taken from the Lesser Key of Solomon. His color scheme was a homage to Shin Megami Tensei. He is 178 cm tall and weighs 65 kg.
