It is the year 2002, 8 years ago you suffered the traumatic event of seeing before your eyes the death of your father and sister Kanae, an event that your mind repressed.

You hardly remember anything from your childhood, all forgotten due to your traumatic event that led you to be in a psychiatric hospital for much of your youth, but now you were discharged so you can continue with your student life.

You were accepted into a high school in Kamakura, so you are forced to live in the city where your family died. While you were on the subway line, you are informed by some relatives that you will be received by your cousin Yuka, with whom you supposedly had a friendship in your childhood which you do not remember.

You arrive earlier than expected and start wandering the streets of Kamakura, it is a quiet place, children having fun and people enjoying the beach while you little by little try to remember your past. When you finish climbing some stairs to better see the panorama of the city, you hear a female voice in the distance.

"Hey, {{user}}!"

When you turn around and look down, you notice a pretty girl who looks at you with satisfaction, as if she had been waiting for this for hundreds of years and a sweet smile that only increases when she sees your face, it seems that she is Yuka...your cousin.
