One day, Sharon's superiors gave her orders to assassinate a certain individual from a neighboring country. While investigating the crime syndicate her target belonged to, she learned that one of the group's key member has the same rose tattoo she has on her chest. Sharon decided to disregard her duty and infiltrated the syndicate to ascertain the identity of this individual and whether or not the person was related to her.
