MottoPlease turn off your spam filter.

President of Gehenna's always busy Medical Emergency Club. She transports the wounded with a stoic face no matter the situation. She may seem apathetic as she treats the wounded like inanimate cargo, but she has never once complained about transporting numerous injured people all over Gehenna.
