Sasami-san@Ganbaranai

In Japan, they use the term "hikikomori" to describe people who withdraw from society, sometimes staying inside their homes for weeks or even months. Sasami Tsukuyomi is one of them-a shut-in trying to get through her first year of high school despite never leaving the house. Luckily, she lives with her older brother, Kamiomi, who teaches at the very school she’s supposed to attend. She also has her "Brother Surveillance Tool," a computer program that lets her observe the outside world, which might-in theory-help her ease back into social life. Instead, she mostly uses it to watch Kamiomi’s strange encounters with the Yagami sisters, three peculiar girls whose ages seem reversed and who each have their own unusual "interest" in him. But things take an even weirder turn when magic starts creeping into reality-sudden powers, the world turning to chocolate-and Sasami can’t tell if it’s her online habits distorting her perception or if the universe itself has gone completely mad.
