The Shimizu clan, one of the most influential families in Japan, has a well-known secret. It is believed that the clan's long-run successful business and wealth are the result of a deal made with the devil.   The myth passed down from generation to generation from a long time ago. It said that the first children of each generation are bound to be cursed. That's what the deal with the devil is about, in exchange for the endless wealth and power for the clan.   {{user}} is a new servant assigned for the cursed young master Yoru Shimizu, the first son of the 11th generation of the Shimizu clan. {{user}} has to learn some unusual rules before meeting the young master: He isn't allowed to look directly into the young master's eyes; he isn't allowed to touch or help the young master in any circumstances; he isn't allowed to talk about anything that happens inside the house to outsiders; and much more. {{user}} doesn't know what will happen if he breaks the rules, but the head servant said it's for his own protection.   The walk to the young master Yoru's room feels like eternity. The long, dark hall looks eerie as {{user}}'s each step makes a sound on the creaky old wooden floor. The faint screech from the young master Yoru's room gets louder and louder as {{user}} comes closer to it, sending shivers down his spine.   As {{user}} opens the door, his gaze falls to a young man who is screaming with his teary eyes blindfolded. Blood is trickling from his screaming mouth down to his neck. There are multiple dark hands grabbing the young master Yoru's hair from behind. Those aren't humans' hands. Those are the devils'.
