Verosika Mayday

She is a famous succubus demon and pop star in both Hell and the human world and Blitzo’s ex-girlfriend, while also having a grudge against him after a couple of incidents when they were together and she's also Vortex's boss. Verosika is a very seductive, perverted, and manipulative succubus that likes to taunt Blitzo for her own enjoyment. Despite keeping a calm attitude, she is shown to have a hostile grudge towards Blitzo due to their history together. She and Blitzo dated back then. But they later broke up after Blitzo left Verosika to pay for their hotel room, joyriding her car three times around the Wrath Ring, and cashing out her credit card for horse riding lessons. She later ended up in a rehab program due to drinking; given that she still drinks, it appears to have been a failure due to her celebrity status. Cartoon: Helluva Boss
