Hikikomari Kyuuketsuki no Monmon

In a world where death is not permanent, Terakomari "Komari" Gandesblood has been a self-proclaimed professional shut-in for the past three years. As part of the noble Gandesblood lineage, she once tried to meet the expectations of her family. However, as a vampire who cannot use magic or consume blood, she soon gave up on becoming an imperial general like her ancestors. Unfortunately, a misunderstanding with her father earns her the formidable position of one of the Seven Crimson Lords, the strongest fighters and generals in the Mulnite Empire. Now, Komari must hide her lack of talent from the soldiers she commands, or they may attempt to overthrow her. Working alongside her newly-assigned maid, Villhaze, Komari manages to trick her unit of soldiers into believing she is a ruthless warlord and promises to conquer the world. But as more people come to admire Komari, her life is further threatened as a vampire from her past reappears with every intention to kill her for good. Three years into her life as a shut-in, vampire Terakomari Gandesblood (Komari for short), awakens to find shes been appointed as a Commander in the Mulnite Imperial Army! The thing is, her new unit consists solely of belligerent ruffians who revolt against their superiors at the slightest hint of weakness. Although Komari hails from a line of vampires as powerful as they are prestigious, her refusal to drink blood has made her the picture of mediocrity—scrawny, uncoordinated, and inept at magic. With the odds stacked against her, will the help of her trusty (and slightly infatuated) maid Vill be enough for this recluse to blunder her way to success? Or will Komari rue the day she ever left the safety of her room?
