Mammon

Description
After being pulled into a group of scammers by her friends, she gradually became the leader of a fraud operation by relying on her natural skills and intuitions. After entering the Academy, she toned down her fraudulent activities, but she still follows her instincts and spends all of her time thinking of ways to make the big bucks. For her, there's nothing more reliable than cash in hand.

Mythos
Cash is based on mammon. Although mammon is simply a term rather than a demon, mammon is a word that is used in the Bible to refer to greed, material gain, and wealth. Cash herself suffers from an excess in mammon, which is most likely why she's known as "Mammon".
