This is one of her signature songs that colored the idol scene of the 80s.
"Nagisa no Haikara Ningyo" is a beautiful song that combines seaside scenes with feelings of love, fully expressing Kyoko Koizumi's pure and lovely charm. "Kaze no Magical" takes a more dreamy approach, effectively using synthesizer sounds unique to the 1980s. Both songs were written by Yasuaki Akimoto, and are still highly regarded today as works of artistic perfection that go beyond the boundaries of idol songs.
