Ingvild made her appearance in True Volume 1, and was singing by the fountain which Issei was killed by Raynare. While biking to his house, Issei hears her singing and follows where its coming from and as she stops singing, she realizes he’s the red dragon they get attacked by the unidentified devils and stands behind Issei. After Issei defeated the unidentified devils, Ingvild was covered in blood in her dress and face and used the handkerchief that Issei gave her to wipe the blood from her face.
