雨の魔女と灰公爵 ～白薔薇が咲かないグラウオール邸の秘密～

"A witch becomes a real person when she knows love." This is a story of witches' secrets and love. A hundred years ago, the kingdom of Astrid was founded by four witches supporting the first king. The Rain Witch Lill's magical powers were unstable due to the shock of her predecessor's death. This is also the reason for the continuous rain. At that time, Duke Leolart visits her and asks her to "find the person who gave her sister's keepsake." Lill accepts the request out of gratitude for her past kindness, but it seems he has another purpose...? "A witch becomes a real person when she knows love." A story of witches' secrets and love that weaves together the past and the present.
