Saikyou no Kensei, Bishoujo Maid ni Tensei Shi Houki de Musou Suru

The strongest Sword Saint in history, Arnoick, has died.
His sword techniques were passed on to his disciples, and it was believed that his story had come to an end—
—but not quite!
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!
