She's a goddess of poverty and part of the nobility in that divine realm. She tried to move into Kohina's house along with the other poverty gods, much to everyone's annoyance.
Like the rest of her kind, just having her around financially drains households—and she absolutely loves money, which is kind of the whole irony of her existence. Her personality is over-the-top and theatrical; fans often note she's basically a living parody of Marie Antoinette with her frivolous attitude. She's known for constantly saying things like "If you have a complaint, come to Versailles" or riffing on the "let them eat cake" line in various forms.
