Natsume was the one responsible for creating the siblings: Serateed, Branowen, Kiara, and Baroqueheat. Although she was supposedly loved by all of the siblings, Serateed had a strong dislike of her. The reasoning is that she blackmailed Serateed into allowing her to experiment the Angel Text on him. If Serateed did not agree, she would instead get another one of the siblings to take his place. Baroqueheat was in love with Natsume, and she was the one who gave him the tattoo which transforms into a sword. Natsume was later killed by her lover, Second.
