Tithe to Tartarus

Inflicted with amnesia, Yumiko Ume Moth has managed to discover the identity of the lost love whom she cannot remember. And she has learned the truth of her mother's murder. The party responsible for the absence of the one and the death of the other appears to be the same: the Supreme Council of Anarchists.
Now she hopes to rescue the brilliant young man who may or may not be her fiance while seeking vengeance for her mother, the Grail Queen. But her only allies are a scatter-brained fairy and the Last Crusade, which consists of a young knight and his dog. Nevertheless, the Foxmaiden will not turn from her path, though all the dark forces of Tartarus stand in her way.
