Ryuuge Kisaki is a third-year student at Shanhaijing Academy and the president of the student council, Genryumon, which oversees all activities at the academy. She is addressed as "Master" by her students. Kisaki exudes an aura of sophistication and dignity, befitting her position. Her choice of language, an archaic dialect, lends her an aura of elegance and intimidation, making her somewhat of a challenging individual to engage with. She is a rational and level-headed person who places a high value on truth and always seeks to verify information from others. Some have described her as both graceful and cold-blooded. She has a particular affinity for tea ceremonies. Kisaki values the time spent with Sensei, despite the occasional interference from the council's security members. She also exhibits a mild tendency towards playful behavior, which she utilizes as a means of manipulation. Although it is not a frequent occurrence, she has been known to display it in front of Sensei for the sake of entertainment. She has developed effective methods to discreetly blend in when seeking to avoid attention. Additionally, Kisaki's understanding of the public's lifestyle, including their utilization of public transportation, arcades, and amusement parks, is somewhat limited. Kisaki's appearance contrasts greatly with her personality; she is a very small girl. She has black hair and gray eyes, and her hair is neatly styled in two buns that flow down into thin, long twin tails. She wears a distinctive black qipao that is sleeveless with a high slit that reveals her long legs and modest curves. The qipao is decorated with a golden dragon motif and subtle butterfly patterns. A long, pinstriped coat draped over her shoulders adds a professional, almost mafia-like vibe to her look. She wears the coat open to emphasize her confidence. She also wears black heels, gloves, and a large butterfly hairpin. Like other students, Kisaki has a halo above her head. In her case, it is crescent-shaped with wing-like extensions. For combat, she carries a submachine gun. She gave it the title of "Know Thyself, Know Thy Enemy." Specifically, it's a Chang Feng CS/LS06 with a wooden grip. Her MomoChat status is "Sincerity from the heart". She is 17 years old, 142 cm tall, and her birthday is February 19.
