Koshi Torako is a top-level high school student, adored by classmates and recognized by society. However, under a carefully crafted honor-student mask hides a legendary delinquent. Good thing for Torako that it's in the past and no one can possibly recognize her now... or so she thought, until one day she meets an unknown creature named Shikanoko Noko (or just Nokotan for friends)! It's unclear what Nokotan is—a human girl or an elk—but in an instant she was able to see (or sniff) through Torako's game. And now it seems she is set to drive Torako crazy! Expect much hilarity in the proces..
