A superb collaboration between two of the greatest electro-swing artist in the Vocaloid world! The lyrics were written by "Yuri Kuriyama" and composed and arranged jointly by "Yuri Kuriyama" and "Nuyuri," resulting in a top-notch electro-swing song while utilizing the characteristics of each."Flower" and "KAFU" sing alternately in a style that matches the complex arrangement, and the chorus, which develops in two stages of mutual unison, is the highlight of the song, raising the tension whether you like it or not. Other highlights are scattered throughout the song, including a thrilling flow of odd time signatures and dubstep in the latter half of the song, and the arrangement by the members of Van de Shop ("Haku Hitoi" on piano and "Koh Hashikura" on brass) is very effective. The lyrics by Yuri Kuriyama also express the pure joy of this collaboration, which is conveyed to the listener. The jacket design was done by Harumotsu, who is also well known for his work on the music videos for "Van de Shop" and "Nanashi Hachiya". Everything is produced with high quality and impeccable workmanship.
