Sasami Tsukuyomi

Sasami Tsukuyomi is a first-year high school student who lives with her older brother Kamiomi. She is a hikikomori (shut-in) and initially refuses to even go to school, but she later begins attending school in February near the end of her first year in high school. At home, Sasami uses a "Brother Surveillance Tool" on her computer to view the outside world. She possesses the power of Amaterasu, unconsciously causing powerful gods to protect her and her brother. For a while, she believed that the power of Amaterasu was transferred to her brother, just to find later that she never lost it at all...
