Marchosias

マルコシアス

aka Claws and Fangs of Violation

The Crimson Lord to whom Margery Daw is bound. He expresses his will through the divine vessel Grimoire, which takes the form of a book. He talks wildly, makes comments without remorse, and often teases Margery, often earning a retaliatory punch. He does genuinely care about her, however, perhaps not in the form of friendship but as a companion in battle.
