Lucifer of Pride, one of the Seven Stakes of Purgatory

Aha... It's Lucifer of Pride.

Lucifer is the eldest sister of the Seven Stakes of Purgatory. When Beatrice needs somebody killed and doesn't want to get her hands dirty, Lucifer is the first to answer the call. She's high-ranked furniture, not an easy demon to summon. She acts tough, but it's a dog-eat-dog world. If she shows the slightest hint of weakness, the other sisters will bully her.

When dealing with the Seven Stakes, you have to watch out for two abilities. First off, Lucifer can summon a beam sword on one arm, like something straight out of a shounen anime. Secondly, she can transform into a stake, bouncing around the room at tremendous speeds like she'd been fired from some sort of gun. All in all, I'd rather not fight her. Still, when someone calls herself 'Lucifer of Pride,' it just kind of makes you want to bully them, doesn't it? Maybe my Pink Trigger will grant me an opening.

At this point in the story, she's probably just waiting on Beatrice's command. I'd imagine she's a little antsy. No one will be killed until late tonight, unless I screw up first.

I have no idea how old she is, but she has the ass of a girl in the prime of her life. Battler was right to comment upon it.
