A large object fell from the sky onto the streets of Lovelick Town. It was a humanoid girl robot—a DigiGirl. Nail, who happened to be driving by, loaded the DigiGirl into his car and took her home. After being repaired by Nail’s younger brother, Yamaguchi-kun, the DigiGirl rebooted. With emotions and a personality of her own, the DigiGirl adapted to human society, winning everyone’s affection with her pure, kind heart and cheerful nature. Eventually, she fell in love with a human boy.
