Plot
Sasami Tsukuyomi, a first-year high school student who is a hikkikomori, lives her life mainly alone, apathetic towards everything (to the point changing and eating became a menial task for her) in a room with her brother, Kamiomi Tsukuyomi. But with all the strange phenomenon caused by ya-o-yorozu no kami, along with "Evil 3 sisters of the Yagami family", it seems that she will be living an unusual daily life even with her shut-in attitude.
