That description is half lying. Also, the mask surprisingly works considering how much toxic gas can still get through, but hey she can block it with magic if it doesn't work.
Original description before I decided to change it before my art teacher questioned me and so I could fit it in that tiny ass box:

> Arie is the CEO of a hidden organization with hundreds of other people working for her who believe they have the same goal as her. Little do they know, that "goal" she's been telling them has been a lie. She says she wants to make the world better, but really, she just wants to cause chaos for fun. Sometimes, she does help take down criminals, but she only does it either for her benefit or for her entertainment. They usually have some kind of rivalry with her, especially the well-known ones, so when she takes them down, considering how shitty the government is in her world, they drop a fairly small charge or two they have on her depending on who the criminal is. But they'll always make sure they have some on her so when they finally capture her, they can finally get rid of her.
> But Arie has her ways of getting away.

Backstory? Not here bro I'll link that when I get the chance to Tumblr post about it. Also that desc isn't done I'm just too lazy to type out the rest cause I lost the original.
