Mahou Sensei Negima!: Mou Hitotsu no Sekai Extra - Mahou Shoujo Yue♥

Separated from Negi and the rest of Ala Alba after the forced teleportation across the Magic World, Yue Ayase awakens at Ariadne Magical Academy with a head injury and no memory of who she is. Taken in by the academy's students, she begins learning magic as though she were starting from zero, even while flashes of her forgotten abilities suggest that her past is anything but ordinary.

As Yue settles into her new surroundings and trains alongside her new companions, her natural talent draws attention and trouble alike. With danger approaching, she must trust instincts she cannot explain and rediscover the strength hidden behind the memories she has lost.
