Coolstreak Cartoons's Leroy Douresseaux comments on how the "love between two people" takes priority over everything else in the manga.[5] Pop Shock Culture's Katherine Dacey commends the manga for "emphasizing steamy encounters between beautiful men in period costume over long-winded political discussions".[6] Mania.com's Nadia Oxford commends Fumi Yoshinaga's artwork but criticises the backgrounds that "remain disappointingly sparse".[7]
