The Flower Princess of Sylph

シルフの花姫

Natalia lost her family, and succeeded the throne to be the King of Ventfleur. She was known as the princess blessed by the spirits--people loved her. However, she was deep in her grief… the only thing that comforted her now was "Sylphide", the holy sword blessed by the wind spirit Sylph. The sword marked her succession to the throne, and it was said that the wielder could see the memories of the past kings by touching the sword. However, Natalia couldn't see anything… although she felt better by holding onto it. One day, a nun named Sara came to her and told her that she will make her healthy. Natalia rejected her first, but Sara won't give up. She was worried about Natalia, but also had a reason she must be by her side. (Source: Kadokawa) Note: Includes two extra chapters.
