Xin Banyue is the Ninth Sister of a sworn brotherhood and a wood‑element ability user. She was scratched by a Level 6 zombie and brutally abandoned by her team. Against all odds she survived, discovering that her ability has a devouring property that grants her fire, water, and earth elements. She is fiercely independent, resilient, and holds deep grudges. After being disillusioned by her former brothers, she leaves the base to survive alone, using Tumi flowers to heal and defend herself.
