Fan Xinglou (范星露), formerly known as Wang Xiaoyuan (汪小苑) while she was the second Banyuu Tenra, is the student council president of Jie Long Seventh Institute. She is later revealed to be the same person as the first and second Banyuu Tenra.
Xinglou has black (purple in the anime) hair with a portion tied into butterfly wings. She is also mentioned to have cute features and look like a child instead of a girl. While she was Xiaoyuan, she had long black hair, loose clothes, and a look that made her seem to be various ages. Xiaofei noted that she had deep eyes that seemed to draw him in.
Xinglou has an interest in training promising people herself, referring to it as "eating food and enjoying the various flavors". Despite having a considerable amount of students that she trains, she has no interest in teaching them how to correctly use their power, sometimes ending up with students such as the Li siblings.
She is referred to as an "existence of another kind" by Helga, and Sylvia was told by the previous student council president to "not get involved more than necessary with the Banyuu Tenra as anything goes". Xinglou is knowledgeable despite her age, leading to rumors about her, though as she doesn't explain anything about it, no one knows the truth. She has had an interest in Ayato ever since the Phoenix Festa and is disappointed that he didn't come to Jie Long.
Xinglou has touched on the topic of her age, once mentioning that she fought the family head of the Night Emit several generations before and lost an arm to him. Also, according to Bujinzai, people like Xinglou grow stronger over time, though she lost half her strength by changing her body to a female child. However, her Seisenjutsu is much stronger as there is more mana in the air than before. It was confirmed by the author that all three Banyuu Tenra are the same person as Xinglou has been creating new bodies using Senjutsu and moving her consciousness into them in order to obey the Stella Carta.
During the beginning years of Asterisk, Xinglou, as the first Banyuu Tenra, arrived and established the basis of what is now known as Jie Long Seventh Institute, coming to be known as its founder. Once she built the Oushinden and trained several Seisenjutsu instructors, she left Asterisk, coming back more than ten years later with a new name, Wang Xiaoyuan, and a new body, soon becoming the second Banyuu Tenra. As the second Banyuu Tenra, she accomplished the Grand Slam, and later became a teacher after graduating. Quitting her job after an unspecified amount of time, she found a six year old Wu Xiaofei in a desolated city, and took him under her wing, training him as her first apprentice. More than ten years after the second Banyuu Tenra left, Xinglou came back to Asterisk as her current self at the age of six along with Xiaofei.

It is considered to be a treasure within Jie Long and no one aside from Xinglou is allowed to touch it. She is also capable of summoning these to her whenever she needs them, which is described as the area around her warping and then the sage tools appearing out of thin air.
