It happened with a slip. Koyomi Araragi thought he was done with the supernatural after his recent brush with vampires but that belief is short lived when Senjyogahara, the aloof girl in school, is as light as a feather. The cause? A crab God with a penchant for the vulnerable. But thats just the tip of the iceberg as shes not the only individual suffering from the effects of their brush with the paranormal. A lost snail who cant find their way home no matter how hard they try, and a mysterious deadly arm that can only bring misery despite how hard one wishes. The forever Mr. Nice Guy Koyomi, cant help but embroil himself into their lives to fix their problems with the aid of Meme Oshino, an expert on these matters.
