Azusa is a new idol who performs under the stage name Happimelily. She suffers from extreme stage fright that causes her to transform into a cold and ruthless idol the moment she steps on stage. One day she comes across a one-horned magical beast named Pechimo and decides to keep it. With Pechimo's help, Azusa tries to overcome her nervousness and become a proper idol. The volume collects the full five-chapter title story along with thirteen additional comedy one-shots by the same author, each featuring rapid-fire wordplay and absurd situations.
