Due to having no physical release outside of concert venues, the song failed to chart on the Oricon Singles Charts. "HUSH" was a hip-hop piece composed by Swedish musical composer and songwriter Louise Frick-Sveen, who had previously worked with South Korean group SF9 for their song "Fanfare" in July along with Albin Nordqvist. The lyrics to "HUSH" were written by Kumi and TEEDA from the group Back-On. The song "Guess Who Is Back" (track #9) was used as the 4th theme song for the 1st season of the anime "Black Clover." This made it the first time since 2012 that Kumi performed a theme song for an anime, the previous being "Go to the top" for the anime "Muv-Luv Alternative: Total Eclipse". Along with the music video for "Hush", three new videos were created and performed for the album: "Watch Out!! ~DNA~", "Haircut" and "Chances All". The three new videos were performed in the same location, with "Haircut" being the main promotional track. The video for "Haircut" opened with the first few seconds of the album's first track, "Introduction ~My music is designed from my DNA~". It shows Kumi with blonde hair as she makes her way to a stylist's station, where they dye her hair in rainbow colors. After she gets up, she walks behind promotional posters for the "DNA" album as her hair changes. In the video, she has several hairstyles, including platinum blonde pigtails with butterflies, before she unveils her current hairstyle of a blonde bob cut. Other scenes in the video include Kumi spray painting a wall while wearing neon boots and a black swimsuit. The video ends with Kumi cutting her hair with scissors, which began the video for "Watch Out!! ~DNA~". "Watch Out!! ~DNA~" was performed in the same location, with Kumi wearing a neon yellow raincoat over a black jumpsuit. The video was predominately a dance number, with Kumi and four background dancers. "Chances All" was composed of the multiple hairstyles she wore in the video for "Haircut", with Kumi singing directly to the camera. Short versions of all three new videos were uploaded to avex's official YouTube on August 9, 2018, to help promote the album. Credits are adapted from album's liner notes
