Also known as: 瀬笈葉
A fanmade Touhou character originally appearing in the fangame Touhou Shizenyu. She was able to fire her own Master Spark without a Mini-Hakkero, which led to her becoming Kirisame Marisa's student in order to learn how to better control it. Later on it's revealed that she was created by Kazami Yuuka in order to absorb the willpower of plants and eventually return it after detoxifying them of the poison they've accumulated from past incidents, causing the wilting incident she was trying to solve.
