Music videos

The music videos for these 4 songs are interconnected starting with Juicy to With Your Smile to I'll Be There to Ningyo-hime. The clearest similarities are among the first three music videos, following a plot regarding Kumi distracting a group of men via seduction and stealing a treasure map, only to be chased while looking for whatever treasures the map leads to. Ningyo-Hime, the final music video in the saga, shows where and what the "triad-treasure" lead to.
