However, Reiko is very particular about winning and will use whatever method she can for her clients, thus causing her to have many enemies inside and outside the law firm. One day, Reiko was sued by a client for extortion and was given a bonus cut. Angered by the treatment, she decides to take a leave of absence and spends her time sending random emails to her acquaintances. The only one who responded to her is Eiji Morikawa, Reiko's ex-boyfriend. However, the email replied that Eiji has passed away. The sender of the email is a mysterious person named Keitaro Shinoda. Reiko later found out that Eiji has left a strange will that says all of my properties will be handed over to the person who killed me.
