"I'm here to have some fun, that's all. I'm just an adrenaline junkie on a power high."

Character 3 of the Superhero Project

Mariko Lupin didn't start out calling herself Ghosttrick, but it was better than the names she came up with so when the media started calling her that she shrugged and rolled with it. A self-proclaimed adrenaline junkie on a power high, she has the ability to phase through objects which she leverages to "borrow" the money of some of the wealthiest people in the world. To the public she's a menace who steals from honest mens fortunes like a leech, to the superhero community she's an anomaly, yet there's some who see her as a better hero than the state-sanctioned superheros. Despite her claims of doing this for nothing more than thrill, she has a strange habit of going out of her way to handle subduing other criminals herself, even ones that aren't direct competition to her. She's even been known to leave clues for heros to help them stop the schemes of other supervillains. Why would someone who commits crimes solely for selfish thrill-seeking be so inclined to have a selfless streak?
