Jois is an alchemist who is employed as a special effects artist at Titania's Cabaret. She is in her mid to late-twenties, rather plain, with brown hair and odd, pale grey eyes. She is very quiet, but very talented. She works closely with Valerien Evrall, so he probably knows her better than anyone, and even he says he doesn't know very much about her personal life or background. Based on a few details, like her tastefully expensive clothing, it is possible she comes from money.
