is a Japanese heavy metal band from Osaka, who released their first album in 1999.
They play quite orthodox heavy metal music, mixed with elements from Japanese folk and pop music, and play both fast, hard songs and slow ballads. Since their debut in 1999, they have appeared in traditional clothing characteristic of Japan's Heian period.
Their name refers to Onmyà Âdà  and the gathering of yin and yang (Inyo in Japanese, formerly Onmyà Â), and the theme of opposites and cosmic dual forces are prevalent in their lyrics. This contrast is also represented by the female and male vocals and two guitarists.
