"S-Since there's nobody here, guess I could sing... Anyway, I am, among Demon Kings the WEAKEST! But you, go and lose your head by my REQUEST!"

Astaroth is the Demon King of Melancholy, and a very popular musician in the earth's virtual world, and she's quite the braggart under this pretense.


Astaroth has two horns curving downwards on the back and sides of her heads behind her ears. She has pink hair done in shoulder-length twintails with two tiny red hats on each side of her head. Astaroth wears an elaborate black-and-red gothic lolita-styled outfit, consisting of ruffles on her shoulder, throat, and right hip; a ribbon on her chest; pink lace on her chest and waist; a double layered skirt; and a ruffled purple hankerchief on her right hip. She wears fingerless gloves with elaborate pieces of metal on her arms (with the right piece being very large and the left piece being very small) and she wears red-and-white striped thigh-high stockings on her legs with black ballet shoes on her feet. She has an axe guitar whose black head and red body are of the same material and appearance as the metal pieces on her gloves.


Though Lady Astaroth might say Lady Belphegor stole the seat of "demon of laziness" from her, in actuality she's a fellow NEET, and probably the only person she could call her friend.

She's quite pessimistic, with a cynical-like nature, and she herself thinks she's weak, a Demon King with too few believers. An obstinate day-dreamer, if she tried her earnest she could act like the strongest Demon King, but she's not that good at speaking in front of everybody. However, once she holds her guitar, it seems she becomes able to convey a few of her feelings though her gloomy melodies.


It is revealed that Astaroth among other things, is a phenomenal musician and singer. Her habit of rapping during conversations instead of talking, shows she has quite the poetic mind. To an extent, Astaroth manipulates peoples emotions via her music, which is rewarded in the form of fame and increasing views of her videos.


  • She is named after Astaroth, a Crowned Prince of Hell.
  • She is the among the youngest of the Demon Kings, older than Beelzebub and Leviathan but around the same age as Belphegor.
  • She and Belial are Demon Kings of former sins, Vainglory and Melancholy were replaced by Pride and Sloth in later beliefs.
