Daisuke Ozasa is the guitarist of Official Hige Dandism and graduated from the advanced course at Matsue College of Technology. His school was next to the school attended by the other three members; because Shimane had few live music venues, people involved in bands often crossed paths, which is how Ozasa met the others. He later formed a band with the three of them, becoming one of Official Hige Dandism's four members.

One work's credits list Daisuke Ozasa as its lyricist, composer, and arranger.

Looking back on the development of the band's sound, Daisuke Ozasa said that the four members had not initially envisioned the style of melody they would later adopt; their current song style only gradually became a defining feature of the band as they played together. During the production of another song, Ozasa considered the guitar tone particularly important, so for the first time he brought in a staff member dedicated to offering guitar advice and prepared multiple guitars and amplifiers to try out.
