Shut-in vampire Terakomari, or Komari for short, awakens from her slumber to find she's been promoted to a commander of the army! The thing is, though, her new squad has a reputation for being violently insubordinate. And although Komari was born to a prestigious vampire family, her hatred of 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 maid be enough for this recluse to blunder her way to success?

An unexplored dungeon, filled with monsters and traps. An expert thief, searching for her lost father. When Clay delves into the dungeon deeper than any adventurer has ever gone, she is offered a job by the dungeon's caretaker! Now, instead of exploring, Clay must learn how to interview new monsters, set traps and position slimes around the dungeon. Will this new career path bring her any closer to finding her father?
