A playable character from Genshin Impact, she is a ninja of the Shuumatsuban in Inazuma. She is capable of summoning or transforming into Muji-Muji Daruma.
Despite being a particularly skilled and capable ninja, Sayu mainly uses her ninjutsu to hide from her work and avoid a certain shrine maiden, allowing her to spend as much time sleeping as possible. While she is renowned for her laziness, other Shuumatsuban members know that she is still very loyal to their cause. Her short height is something Sayu is very unsatisfied with, believing that sleeping will help her grow taller and will not allow people to headpat her as she believes it will impede her growth.
