"...Huh? W-what?" Terakomari, a young girl known as "Mari" who spends the day at home, gets elevated to the rank of imperial general when she wakes up. Mari also commands a force that is brutal, bloodthirsty, and filled with criminality. Mari was born into a well-known vampire family, but she cannot utilize magic, has motor issues, and isn't tall enough due to her hatred of blood. When she was at her wits' end, her (alleged) trusted maid Villhaze offered this advice: "Plz leave it to me. I'll see to it that they don't misunderstand!" Mari wins numerous conflicts by using bluff and good fortune, and a happy fantasy tale is born. Despite spending the entire day at home, Mari is "a kid who can do anything if he works hard"?—Bilibili TV
