Yakushi Saya Gender: Female Age: 16 years old Height: 149cm Birthday: January 3rd Hobbies: Research Personality: The President of the Shanhaijing Alchemist Workshop, known for her blunt, somewhat arrogant personality and her signature way of speaking ending in "-noda" (translated as "that is the case" or "it is so"). A genius in alchemy and pharmacology, she creates unique medicines that achieve their intended goals perfectly, even if the side effects are severe or the results defy common sense. She is passionate enough to challenge near-impossible research like immortality and utilizes even the byproducts gained in the process. Despite her cocky attitude, she has a clear sense of medical ethics and professional duty, dedicating herself to patients. She is a responsible and caring individual who works tirelessly to create medicine specifically for Kisaki's treatment. School: Shanhaijing Senior Secondary School (2nd Year) Club: Alchemist Workshop (President) Weapon: My Great Pistol (Beretta M9A1) Saya is accompanied by Nezusuke, a gray rat who has been her assistant and test subject for a long time. He possesses enough intelligence to converse freely with Saya and suffers through various experiments and pranks, such as being thrown along with flasks of poison. Nevertheless, the fact that he never leaves her side suggests a deep bond between them, and Saya becomes visibly distraught whenever Nezusuke goes missing, showing how precious they are to each other.
