The duo independently released their self-titled debut album Eufonius (2003) at the M3 dōjin music convention, followed by their independently released debut single "Guruguru" (2004) also at M3. Eufonius made their major debut on King with their second single "Habataku Mirai" (2004), which appeared on their major debut album Subarashiki Sekai (2006). "Habataku Mirai" was the first release by Eufonius to chart on the Japanese Oricon charts, peaking at No. 80. Th
