In a Japan where the Taisho Era didn't end after 15 years but went on for another 10 additional years the eldest daughter of the financially declining Kuze family, Tsugumi, resolves herself to a marriage she doesn't desire for the sake of her family. However, Hitaki, her younger brother, vehemently opposes the marriage and after a fight with Tsugumi, shuts himself away in his room and attempts to kill himself. Tsugumi blames herself for her brother's suicide, but two mysterious men appear identifying themselves as part of the Imperial Library Intelligence Asset Management Bureau and reveal that her brother's suicide might not be as clear-cut as it seems.
