 In 2006, Mizuguchi pursued his love of technology and electronic music, founding the band Genki Rockets with a consistent group of collaborators, including songwriter and producer Kenji Tamai, as well as singers Rei Yasuda and Nami Miyahara.Mizuguchi would write all of the album's lyrics and contribute melodic ideas to Tami, who would then work on the tracks in the studio.Described as a 'hybrid unit' by Mizuguchi, the vocals of the two singers were digitally combined to sound like one singer, while Rei represented the visual identity of the 'band.'
