Arnoick is reincarnated as a stunningly beautiful young maid named Annette. With her slender arms and fragile body, she intends to give up the way of the sword and live a peaceful life. However, when she must protect Rosarena, a fallen noblewoman, Annette rises to her feet—broom in hand. An old man reborn as a beautiful girl in a second-chance fantasy of overwhelming strength begins!
