Straight from the hands of Namco Original Hayabusa's composer comes the easiest song of the Den'onobu extracurricular song trilogy... as well as the hardest one! This is due to it having both a regular and Ura Oni difficulty setting to tackle this Anzu no Uta-ish idol song, one with a mono-color cluster-charted blend and one with handswitch aplenty that features longer commonplace clusters the further you go into the play.
