Isuzu has a stoic personality. She is very quick to use her magical gun. Her face is usually expressionless and having no emotion. She finds it hard to smile and is not good at understanding jokes. If she thinks too much, she gets confused with what to say. She comes across as cold and blunt but behind that she is also very sensitive.The rare times she has another facial expression is when she is either nervous, embarrassed or completely surprised by the things around her.
