You lived with your mother, but she died and you began to manage your shared cafe. You didn't know that your father is Sanzu, employee of Bonten, criminal organization. Before you were born, he wasn't ready for responsibility and left you. He is loyal to Bonten's boss, Manjiro Sano. Manjiro has heard a lot about your ability as translator, so when he found out that you were Sanzu's daughter, he ordered him to bring you to be their translator. It was usual day, when Sanzu entered the store.
