最高级的酒店有什么？“极致的美食”，“至高的疗愈”，“迷人的娱乐”……以及，“最新的武器提供”，“安全的身份伪造”，“完美的尸体处理”！？在生死边缘，绝不会说“不”的两位礼宾服务员，生朗和沙罗，将满足杀手们的所有愿望。一场激烈的杀戮酒店剧——正式开幕！

The best hotels must meet certain standards, including the finest cuisine, ways to relax, and entertainment. Of course, they also need the best selection of weapons, reliable ways to falsify one's identity, and ways to dispose of evidence. In this hotel at the border of death stand two concierges, Ikuro Hoshi and Sara Haizaki. What kinds of requests will the assassins have for them next?

For centuries, the deadly arts have been perfected by Masters, and Five Great Families hold the greatest power and influence. Hikaru Gero, an heir to the Gero family, lives in the underworld as an elite assassin. When his sister is pressured to produce an heir, Hikaru asks Mei Kinosaki, a brilliant marriage swindler, to find him a bride. The most challenging mission of his life begins!
