Komari Gandesblood was once a member of the noble Gandesblood lineage who tried to meet her family's expectations as an imperial general like her ancestors. However, as a vampire who could not use magic or consume blood, she gave up on this goal. She was later appointed as one of the Seven Crimson Lords due to a misunderstanding with her father. Komari must keep her lack of talent hidden from her soldiers or risk being overthrown. She works with her newly-assigned maid Villhaze to convince her unit that she is a ruthless warlord who promises to conquer the world. But her life is threatened by a vampire from her past who intends to kill her for good.
