Mystake is somewhat impolite but kind to some people. She pretends not to have or know certain things, but after being paid or recognizing people she knows, she gives them what they're asking for. She is said to have made mistakes in the past, hence her name. She had learned from her mistakes. She is wise. Mystake is also brave enough to participate in mission risky missions. Even though she's an Oni, a being of destruction, she is good. She shifts to a human form so she hides that she's an Oni
