A character from Girls' Frontline Neural Cloud. She is an entropized version Sol (Neural Cloud), created using the remains of her core. She is formally introduced during part 1 of Gloaming Finale. Due to the events in Gloaming Finale she co-exists as a separate individual from Sol. Sol gives her the name "Sunna" so she would have her own name, and one that has equal meaning to her own as both a name for the Sun and the name of a Sun deity.
Her outfit consists of a cropped black jacket, Black Gloves, Black Pants, and black Thigh Boots.
