She noted that "Freesia" has an oriental atmosphere, with the first part having the image of a small room that opens up as a result of becoming rusty; the song's oriental atmosphere also influenced its music video. The appearance of the single's title on the cover, as well as the cover itself, were meant to be reminiscent of a retro 7-inch single, with her emphasizing this point by holding a vintage microphone. For the single's B-side "JÃ Ânetsu no Te Amo", she aimed for the song to have a Latin flavor, with the song featuring a Spanish guitar among other influences.

In an interview with Natalie, Amamiya detailed the creation of her EP "Dà Âkasen".

She wanted to release a work were all the songs were written and composed by her, using the skills she learned while spending her free time during the pandemic. The lead track "Trigger" was inspired by her fondness for jazz music, and she wanted to include at least one jazz song in the EP. The song "Tokai Tà Âhikà  (Neon Escape)" was written while imagining Akina Nakamori, one of her favorite singers, and was based on the idea of a woman from the country arriving in Tokyo and becoming tired of the city life. She wanted the song to sound like a typical Japanese pop song and include common words. The song "Hatsukà Âyà Â" was inspired by her love of enka, while the song "Maria ni Kanpai" was inspired by Linda Yamamoto and the Shà Âwa era; she had a particular fondness for "Maria ni Kanpai" despite not being the EP's lead track, so she decided to take the lyric "Dà Âkasen" from the song and use it as the EP's subtitle. The last song "Potsuri, Ai" focuses on a failed long-distance relationship and was partly based on the story of one of her staff members.
