My Adopted Sister Is Actually a Magical Girl

Pei Yi'an has been haunted by the same dream recently. Just when he was disturbed by this strange cycle, his father suddenly dropped a bombshell: he was going to remarry, and Pei Qian'an was about to have a adopted sister. He thought it was the warm unfolding of the "sister descended from the sky" in a youth drama, but when his new sister stood in front of him, Pei Qian'an realized that reality was more bizarre than the dream - she was actually a real magical girl! The ordinary daily routine collapsed in an instant, and his fantasy world officially began.
