Personality: She believes ghosts should be beaten down with firepower. Every conversation and action concludes with "firepower." She is clumsy and acts boldly without being discouraged. She is shameless and approaches everything seriously, but because her conclusions are always off-mark, she is treated as a "fool" or a "troller." She has a fun chemistry with the realistic Iran, as they bicker constantly. Usually a troublemaker and eccentric, but when in danger, she exerts the "firepower" she believes in to protect her friends more reliably than anyone else. Appearance: Long red hair. Black eyes.
