Terakomari, or Komari for short, a shut-in vampire, awakens from her slumber to find herself promoted to army commander! Her new squad, on the other hand, has a reputation for being violently insubordinate. Despite being born into a prominent vampire family, Komari’s hatred of blood has left her scrawny, uncoordinated, and magically inept. With the odds stacked against her, will her faithful maid’s assistance be enough to propel this recluse to success?
