An upper-class young man named Kō "Riku" Ichinomiya meets a beautiful homeless girl named Nino from the banks of Arakawa River, where many of Tokyo's most unusual residents live. The denpa-kei sub-genre of stories revolves around quirky people's lives; the sub-genre is named after the premise that bizarre behaviors are caused by electromagnetic waves (denpa).
