Powers & Abilities
She's too strong as mention that she is the one who try to usurp the royal throne in the Demon World. Seems like she's the one who gives power to Shinobu Takamiya. As seen on chapter 207 page 9, Lucifer put up her hand showing that she is releasing power but as you can see in the manga, Shinobu Takamiya is the one who made the attack and this attack made Oga and Beel throw up. But the worst thing she did is taking Furuichi's heart by her hands. This move do not use any spell. Lucifer is truly have possess a great power that most of the demons don't have.
