Helluva Boss is a spin-off adult animated web series and sister show of the Hazbin Hotel franchise.
The series takes place within the same universe as Hazbin Hotel but features a new cast of characters, a new tone, and a new story.

The series follows the employees of I.M.P. (Immediate Murder Professionals), an imp-run assassination company in Hell, on their
many different jobs. The members of I.M.P. include Blitzo (pronounced "Blitz"), the boss of the venture, along with weapons specialist Moxxie,
powerhouse Millie, and receptionist hellhound Loona. With the help of an ancient book obtained from Stolas,
a Goetial demon of Hell, they access the human world to complete their tasks.

Verosika Mayday

"Alright, Spring Breakers! Y'all ready to get fucked up and make some bitchin' bad choices?!"

Verosika Mayday is a succubus demon and a famous popstar in both Hell and the living world. She is also an ex-girlfriend of Blitzo, making her debut as the main antagonist in "Spring Broken".

As a succubus demon, Verosika is actively seductive and flirtatious, attributes she intigrates into her famous popstar persona as a means of manipulation. Despite her star-status, fame and confidence, she also appears somewhat jaded and is nursing a drinking problem, something she has previously been to rehab for.

Verosika is highly competitive, but she also is petty and mean-spirited. She doesn't take losing well, particularly to Blitzo, with whom she shares a romantic history - a relationship that did not end well and it is implied to be a source of bitterness for her. Despite being Succubi, Verosika and her group appear to have certain standards when in comes to sexual partners.

PS: Ok i get it. She's literally a succubi. I SEE YA-
