The term hikikomori refers to individuals who have become extremely reclusive and refuse to leave their homes for extended periods of time. For Sasami Tsukuyomi, this phenomenon is more than just a word as she struggles with social withdrawal during her first year of high school. However, she has the support of her older brother Kamiomi, who teaches at the same school. Additionally, Sasami utilizes a tool called "Brother Surveillance Tool" to view the outside world through her computer and adjust to interacting with people again. While this tool primarily allows Sasami to observe her brother's interactions with three sisters named Yagami, who appear to have reversed ages and various interests in Kamiomi, things become even more bizarre as magical powers and chocolate transformations begin to occur. It is unclear whether the web is warping Sasami's brain or if the universe itself is going mad.
