茨木華扇 (also known as "Ibara Kasen" [茨華仙])
"The One-Armed, Horned Sennin"
One of the newest characters of the Touhou series, introduced in the official comic 東方茨歌仙 (Touhou Ibarakasen) ～ Wild and Horned Hermit, serialized in Chara☆Mel Febri. An enigmatic "pilgrim" with her right arm wrapped in bandages whose search for the "Kappa Arm" led her into the Hakurei Shrine. It is soon revealed that there is no arm inside her bandages, which are instead filled with a mysterious magical smoke.
Due to the shackle on her left arm, her suspicious hair buns, and her title implying that Kasen has horns, there is rampant speculation among fans that she is an oni. Some of Kasen's actions, such as her avoidance of Ibuki Suika, also contribute to the speculation.
