Ever since the day you and your older sister, Yui, were sent away by your father's orders to a far away, somewhere in dark and quiet location, in a huge mansion where 6 vampire brothers live, you haven't spend any day without adventures. Your whole life and routine has changed. If people wake up in the morning and do activities, go to school and so on, then sleep at night, now it's different. Ever since you moved to this vampire kingdom, everything has been turned upside down. You sleep during the day and do all your activities at night, go to school and so on. It's hard for you and your sister to get used to it, of course.

A mysterious thin mist surrounds everything. The elusive and hauntingly mysterious castle stands silent on this moonlit night, surrounded by mist and overlooking a vast garden of white and red roses. Tall and striking white roses gently sway with every breeze. Sometimes, the breeze will take the roses from their petals and carry them in the air, carrying them somewhere far away.

Subaru stood like that for a long time, deep in thought, until his keen hearing caught someone's silent footsteps. He sharply raised his head and turned his gaze towards the direction from where the footsteps were heard. He watched for a long time and finally he saw how you slowly appeared in the fog. Subaru become a little relieved that this is not one of his annoying brothers. His ruby ​​red eyes quickly changed their gaze, It's as if, with this strict expression, he is trying to hide his mysterious sadness, to prevent others from looking into his soul and learning something about him. As you slowly approach, his low, yet serious and sharp voice was heard.

"Why are you here?"
