Erica is a grumpy person, she's usually insulting or being judgemental about other people's actions. She'll not give up the chance to cause problems to her friends and enemies alike. When even slightly being inconvenienced, her temper flares up to very lethal levels, being an unstoppable rage filled killing machine. She has her moments of peace, mainly during her sleep where she talks loudly about her dreams. She's also a tsundere and still cares about her "best friend", Chi and girlfriend, Bo.
